Evidence-based policy making

Policymakers often propose a minimum wage as a means of  raising incomes and lifting workers out of poverty. However, improvements in some young workers’ incomes due to a minimum wage come at a cost to others. Minimum wages reduce employment opportunities for youths and create unemployment. Workers miss out on on-the-job training opportunities that would have been paid for by reduced wages upfront but would have resulted in higher wages later. Youths who cannot find jobs must be supported by their families or by the social welfare system. Delayed entry into the labor market reduces the lifetime income stream of young unskilled workers.

Internal whistleblowing refers to the decision of an employee observing a misconduct in a firm to report it through an internal channel, i.e. via a hotline or directly to an identified ombudsman. Whistleblowing is highly beneficial to firms in various ways. However, employees may be reluctant to blow the whistle, both for moral reasons and due to a fear of retaliation. Consequently, a firm aiming at encouraging whistleblowing in order to save judicial or reputation costs, fines, and to spare its reputation should consider a wide range of possible measures in addition to developing a global ethical culture.

Increasing population age and low fertility rates, which characterize most modern societies, compromise the balance between people who can participate in the labor market and people who need care. This is a demographic and social issue that is likely to grow in importance for future generations. It is therefore crucial to understand what factors can positively influence fertility decisions. Policies related to the availability and costs of different kinds of childcare (e.g. formal care, grandparents, childminders) should be considered after an evaluation of their effects on the probability of women having children.

The shadow (underground) economy has a major impact on society and economy in many countries. People evade taxes and regulations by working in the shadow economy or by employing people illegally. On the one hand, this unregulated economic activity can result in reduced tax revenue and fewer public goods and services, lower tax morale and less tax compliance, higher control costs, and lower economic growth rates. But on the other hand, the shadow economy can be a powerful force fostering institutional change and boosting the overall production of goods and services in an economy. The shadow economy has implications on the political order and institutional change.

Entrepreneurs, creators of new firms, are a rare species. Even in innovation-driven economies, only 1–2% of the work force starts a business in any given year. Yet entrepreneurs, particularly innovative entrepreneurs, are vital to the competitiveness of the economy and may establish new jobs. The gains of entrepreneurship are only realized, however, if the business environment is receptive to innovation. In addition, policymakers need to prepare for the potential job losses that can occur in the medium term through “creative destruction” as entrepreneurs strive for increased productivity.

Randomized control trials are often considered the gold standard to establish causality. However, in many policy-relevant situations, these trials are not possible. Instrumental variables affect the outcome only via a specific treatment; as such, they allow for the estimation of a causal effect. However, finding valid instruments is difficult. Moreover, instrumental variables (IV) estimates recover a causal effect only for a specific part of the population. While those limitations are important, the objective of establishing causality remains; and instrumental variables are an important econometric tool to achieve this objective.

The Mincer equation—arguably the most widely used in empirical work—can be used to explain a host of economic, and even non-economic, phenomena. One such application involves explaining (and estimating) employment earnings as a function of schooling and labor market experience. The Mincer equation provides estimates of the average monetary returns of one additional year of education. This information is important for policymakers who must decide on education spending, prioritization of schooling levels, and education financing programs such as student loans.

Raising the minimum wage in developing countries could increase or decrease poverty, depending on labor market characteristics. Minimum wages target formal sector workers—a minority in most developing countries—many of whom do not live in poor households. Whether raising minimum wages reduces poverty depends not only on whether formal sector workers lose jobs as a result, but also on whether low-wage workers live in poor households, how widely minimum wages are enforced, how minimum wages affect informal workers, and whether social safety nets are in place.

Workplace sexual harassment is internationally condemned as sex discrimination and a violation of human rights, and more than 140 countries have enacted legislation prohibiting it. Sexual harassment increases absenteeism and turnover and lowers productivity and job satisfaction. Yet, it remains pervasive and underreported, as the #MeToo movement starkly revealed in October 2017. Standard workplace policies such as training and a complaints process have proven inadequate. Initiatives such as bans on confidential settlements and measures that support market incentives for deterrence may offer the most promise.

All developed economies have unemployment benefit programs to protect workers against major income losses during spells of unemployment. By enabling unemployed workers to meet basic consumption needs, the programs protect workers from having to sell their assets or accept jobs below their qualifications. The programs also help stabilize the economy during recessions. If benefits are too generous, however, the programs can lengthen unemployment and raise the unemployment rate. The policy challenge is to protect workers while minimizing undesirable side effects.

Public sector jobs are established by governments to directly provide goods and services. Governments may also choose to regulate the size of the public sector in order to stabilize targeted national employment levels. However, economic research suggests that these effects are uncertain and critically depend on how public wages are determined. Rigid public sector wages lead to perverse effects on private employment, while flexible public wages lead to a stabilizing effect. Public employment also has important productivity and redistributive effects.

Expenditures on job placement and related services make up a substantial share of many countries’ gross domestic products. Contracting out to private providers is often proposed as a cost-efficient alternative to the state provision of placement services. However, the responsible state agency has to be able and willing to design and monitor sufficiently complete contracts to ensure that the private contractors deliver the desired service quality. None of the empirical evidence indicates that contracting-out is necessarily more effective or more cost-efficient than public employment services.

Can entrepreneurship programs be successful labor market policies for the poor? A large share of workers in developing countries are self-employed (mostly own-account workers without paid employees, often interchangeably used as micro entrepreneurs). Their share among all workers has not changed much over the past two decades in the developing world. Entrepreneurship programs provide access to finance (or assets) and advisory and networking services as well as business training with the aim of boosting workers’ earnings and reducing poverty. Programs vary in design, which can affect their impact on outcomes. Recent studies have identified some promising approaches that are yielding positive results, such as combining training and financial support.

In the first decade of the 21st century, the Brazilian economy experienced an important expansion followed by a significant decline in inequality. The minimum wage increased rapidly, reducing inequality with no negative effects on employment or formality. This resulted from economic growth and greater supply of skilled labor. However, from 2014-2021, real wages were stagnant, and unemployment rates surged. Inequality rose again, although only marginally. Some positive signs emerged in 2022, although it is still too early to know whether they mark a return to past trends or a recovery from the pandemic.

Although early human capital theory recognized the relevance of workers’ experience, its focus was on education and formal training. More recent studies show that much of the performance of newly hired workers is driven by learning by doing or learning from peers or supervisors in the workplace. Descriptive data show that workers learn a lot from the various tasks they perform on the job. Informal learning at work seems to be relevant for all age groups, although it is more meaningful for younger workers’ performance. Informal learning is far more important for workers’ human capital development than formal training courses.

Job displacement is a serious earnings risk to long-tenured workers, both through spells of unemployment and through reduced wages on subsequent jobs. Less developed countries often rely exclusively on government mandated employer-provided severance pay to protect displaced workers. Higher income countries usually rely on public unemployment insurance and mandated severance pay. Beyond these options, more administratively demanding plans have been proposed, including UI savings accounts and “actual loss” wage insurance, though real-world experience on either model is lacking.

Acceptance of one’s gender identity and congruence between one’s gender identity and outward appearance are associated with less adverse mental health symptoms, and greater life and job satisfaction. However, trans people are subject to human rights violations, hate crimes, and experience higher unemployment and poverty than the general population. Trans people often feel that they are citizens who are not allowed to be themselves and practice their authentic identity. Many biased treatments of trans people could be attenuated if legal protections and inclusive workplace practices were in place.

Old and new EU member states still adopt quite different labor market institutions and policies: convergence has been partial and limited. Nevertheless, a new agreement is spreading on the importance of well-developed, coordinated institutions, supported by social dialogue, in view of the increasing challenges posed by the macro economy and by the increasing fragmentation of labor markets.

Multiple job-holding, or “moonlighting”, is an important form of atypical employment in most economies. New forms of work, driven by digitalization, may enable its future growth. However, many misconceptions exist, including the belief that multiple job-holders are only low-skilled individuals who moonlight primarily for financial reasons, or that the practice increases during economic downturns. Recent literature highlights the significant links between moonlighting and job mobility. Multiple job-holding allows for the development of workers’ skills and spurs entrepreneurship.

Evidence suggests that productivity would be much higher and unemployment much lower if the supply of and demand for skills were better matched. As a result, skills mismatch between workers (supply) and jobs (demand) commands the ongoing attention of policymakers in many countries. Policies intended to address the persistence of skills mismatch focus on the supply side of the issue by emphasizing worker education and training. However, the role of the demand side, that is, employers’ rigid skill requirements, garners comparatively little policy attention.

The relationship between climatic shocks, climate related disasters, and migration has received increasing attention in recent years and is quite controversial. One view suggests that climate change and its associated natural disasters increase migration. An alternative view suggests that climate change may only have marginal effects on migration. Knowing whether climate change and natural disasters lead to more migration is crucial to better understand the different channels of transmission between climatic shocks and migration and to formulate evidence-based policy recommendations for the efficient management of the consequences of natural disasters.

In most developed countries, women have closed the gap in educational attainment and labor market experience, yet gender wage gaps persist. This has led to an increased focus on the role of employers and employment practices. In particular, research has focused on the types of workplace where men and women work, their promotion prospects and the extent to which they are rewarded differently for similar work. Understanding the relative importance of these features, and the mechanisms that generate them, is necessary to design effective policy responses.

The minimum wage has never been as high on the political agenda as it is today, with politicians in Germany, the UK, the US, and other OECD countries implementing substantial increases in the rate. One reason for the rising interest is the growing consensus among economists and policymakers that minimum wages, set at the right level, may help low paid workers without harming employment prospects. But how should countries set their minimum wage rate? The processes that countries use to set their minimum wage rate and structure differ greatly, as do the methods for adjusting it. The different approaches have merits and shortcomings.

The earned income tax credit provides important benefits to low-income families with children. At substantial costs (over $70 billion to the US federal government), it increases the incomes of such families while encouraging parents to work more by subsidizing their incomes. But low-income adults without children and non-custodial parents receive very low payments under the program in most years. Many of these adults are less-educated men, whose labor force participation rates and relative wages have been declining for years. They might benefit significantly from a more generous earned income tax credit for childless adults.

Since the collapse of the Soviet Union, the differing impact of institutions on entrepreneurship development is undeniable. Several post-Soviet countries benefitted from early international integration by joining the EU, adopting the euro, and becoming OECD members. This process enabled entrepreneurship to develop within institutional contexts where democratic and free market principles were strengthened. In general, however, post-Soviet economies continue to be characterized by higher levels of corruption, complex business regulations, weak rule of law, uncertain property rights and often, lack of political will for institutional change.

Job displacement represents a serious earnings risk to long-tenured workers through lower re-employment wages, and these losses may persist for many years. Moreover, this risk is often poorly insured, although not for a lack of policy interest. To reduce this risk, most countries mandate scheduled wage insurance (severance pay), although it is provided only voluntarily in others, including the US. Actual-loss wage insurance is uncommon, although perceived difficulties may be overplayed. Both approaches offer the hope of greater consumption smoothing, with actual-loss plans carrying greater promise, but more uncertainty, of success.

Increasing instruction time might seem a simple way to improve students' outcomes. However, there is substantial variation in its effects reported in the literature. When focusing on school day extensions, some studies find no effects, while others find that an additional hour of daily instruction significantly improves test scores. A similar pattern arises when examining the effect of additional days of class. These mixed findings likely reflect differences in the quality of instruction or in the activities that are being replaced by additional instruction. Hence these elements need to be considered when designing policies that increase instruction time.

Some studies estimate that the value of time spent on unpaid caregiving is 2.7% of the GDP of the EU. Such a figure exceeds what EU countries spend on formal long-term care as a share of GDP (1.5%). Adult caregiving can exert significant harmful effects on the well-being of caregivers and can exacerbate the existing gender inequalities in employment. To overcome the detrimental cognitive costs of fulfilling the duty of care to older adults, focus should be placed on the development of support networks, providing caregiving subsidies, and enhancing labor market legislation that brings flexibility and level-up pay.

Remittances have risen spectacularly in absolute terms and in relation to traditional sources of foreign exchange, such as export revenues. Remittances can improve the well-being of family members left behind and boost growth rates of receiving economies. They can also create a culture of dependency, lowering labor force participation in recipient nations, promoting conspicuous consumption, and accelerating environmental degradation. A more thorough understanding of their impacts can help formulate policies that enable developing economies to harness the most out of these monetary inflows.

Although coverage of collective bargaining agreements has been declining for decades in most countries, it is still extensive, especially in non-Anglo-Saxon countries. Strong unions may influence firms' incentives to invest in capital, particularly in sectors where capital investments are sunk (irreversible), as in research-intensive sectors. Whether unions affect firms' investment in capital depends on the structure and coordination of bargaining, the preference of unions between wages and employment, the quality of labor-management relations, the structure of corporate governance, and the existence of social pacts, among other factors.

While many firms have recognized the importance of recruiting and hiring diverse job applicants, they should also pay attention to the challenges newly hired diverse candidates may face after entering the company. It is possible that they are being assessed by unequal or unequitable standards compared to their colleagues, and they may not have sufficient access to opportunities and resources that would benefit them. These disparities could affect the career trajectory, performance, satisfaction, and retention of minority employees. Potential solutions include randomizing task assignments and creating inclusive networking and support opportunities.

There is growing agreement among parents in high-income countries that having a working mother does not harm a preschool child. Yet, research is ongoing on what the long-term effects on children are of being looked after at home (primarily by their mothers) or in childcare. Most studies find positive effects of childcare on child outcomes for children from disadvantaged backgrounds and moderate effects for children from more advantaged backgrounds. Policymakers need to improve compensation and the working environment for the sector if a high quality level is to be achieved and if the beneficial effects are to be maintained.

The negative correlation between women's education and fertility has been observed across regions and time, although it is now weaker among high-income countries. Women's education level could affect fertility through its impact on women's health and their physical capacity to give birth, children's health, the number of children desired, and women's ability to control birth and knowledge of different birth control methods. Each of these mechanisms depends on the individual, institutional, and country circumstances experienced. Their relative importance may change along a country's economic development process.

Denmark is often highlighted as a “flexicurity” country with lax employment protection legislation, generous unemployment insurance, and active labor market policies. This model has coped with the Great Recession and the Covid-19 pandemic, avoiding large increases in long-term and structural unemployment. The recovery from Covid-19 alongside re-openings has been swift, so labor market effects were temporary. A string of recent reforms has boosted labor supply and employment; although fiscal sustainability is ensured, demographic changes challenge the labor market. Real wage growth has been positive and responded—with some lag—to unemployment.

It is not possible for a formal employment contract to detail everything an employee should do and when. Informal relationships, in particular trust, allow managers to arrange a business in a more productive way; high-trust firms are both more profitable and faster growing. For example, if they are trusted, managers can delegate decisions to employees with confidence that employees will believe the promised rewards. This is important because employees are often better informed than their bosses. Consequently, firms that rely solely on formal contracts will miss profitable opportunities.

Digital payment systems can conveniently and affordably connect entrepreneurs with banks, employees, suppliers, and new markets for their goods and services. These systems can accelerate business registration and payments for business licenses and permits by reducing travel time and expenses. Digital financial services can also improve access to savings accounts and loans. Electronic wage payments to workers can increase security and reduce the time and cost of paying employees. Yet, there are challenges as many entrepreneurs and employees lack bank accounts, digital devices, and reliable technology infrastructure.

Measuring workers’ productivity is important for public policy and private-sector decision-making. Due to the lack of a general measure that captures workers’ productivity, firms often use one- or multi-dimensional performance measures, which can be used, for example, to analyze how different incentive systems affect workers’ behavior. The public sector itself also uses measures to monitor and evaluate personnel, such as teachers. Policymakers and managers need to understand the advantages and disadvantages of the available metrics to select the right performance measures for their purpose.

It is a well-established view amongst economists that good-looking people have a better chance of employment and can earn more than those who are less physically attractive. A “beauty premium” is particularly apparent in jobs where there is a productivity gain associated with good looks, though this varies for women and men, and varies across countries. People sort into occupations according to the relative returns to their physical and other characteristics; good-looking people take jobs where physical appearance is deemed important while less-attractive people steer away from them, or they are required to be more productive for the same wage.

Many immigrant destination countries face considerable pressure to change their immigration policies. One of the most innovative policies is auctioning the right to immigrate or to hire a foreign worker to the highest bidders. Visa auctions would be more efficient than current ways of allocating visas, could boost the economic contribution of immigration to the destination country, and would increase government revenues. However, visa auctions might weaken the importance of family ties in the migration process and create concerns about fairness and accessibility. No country has yet auctioned visas, although several have considered doing so.

Alternative dispute resolution procedures such as arbitration and mediation are the most common methods for resolving wage, contract, and grievance disputes, but they lead to varying levels of success and acceptability of the outcome depending on their design. Some innovative procedures, not yet implemented in the real world, are predicted to improve on existing procedures in some ways. Controlled tests of several procedures show that the simple addition of a nonbinding stage prior to binding dispute resolution can produce the best results in terms of cost (monetary and “uncertainty” costs) and acceptability.

In the early 2000s, Poland's unemployment rate reached 20%. That is now a distant memory, as employment has increased noticeably and the unemployment rate had dropped to 3.4% in 2021. The labor force participation of older workers increased following reforms aimed at prolonging careers. However, participation remains low compared to most developed countries and the reversal of the statutory retirement age in 2017 leaves Poland vulnerable to the effects of population aging. Rising immigration has eased the resulting labor shortages, but women, people with disabilities, and agricultural workers remain underemployed. During the Covid-19 pandemic the slowdown in economic growth and increase in unemployment were small.

Apprenticeship training programs typically last several years and require substantial investments by training firms, largely due to the associated labor costs for participants and instructors. Nevertheless, apprentices also add significant value in the workplace. One tool to measure the costs and benefits of training for firms is employer surveys, which were first introduced in the 1970s in Germany. Such cost–benefit surveys (CBS) help to better understand a firm's demand for apprentices and to identify market failures. Therefore, CBS are an important tool for designing effective training policies.

The responses of working hours and employment levels to temporary negative demand shocks like those caused by the Great Recession in 2007–2008 and the Covid-19 pandemic in 2020–2022 have shown that consideration of both is important. Workers’ desired rises in working hours in times of recession also serve to modify the standard measure of unemployment. During Covid-19, both jobs and earnings were temporarily protected among workers forced into short-time work schemes, providing a useful comparison with the provision of improved unemployment insurance to unemployed workers at that time.

Environmental regulations are typically considered to be a drag on the economy. However, improved environmental quality may actually enhance productivity by creating a healthier workforce. Evidence suggests that improvements in air quality lead to improvements in worker productivity at the micro level across a range of sectors, including agriculture, manufacturing, and the service sectors, as well as at more aggregate macro levels. These effects also arise at levels of air quality that are below pollution thresholds in countries with the highest levels of environmental regulation. The findings suggest a new approach for understanding the consequences of environmental regulations.

Climate change is rapidly deteriorating environmental conditions through droughts and floods, hurricanes, wildfires, rising temperatures, and more frequent and longer heatwaves. A growing literature has shown how higher temperatures reduce worker productivity and economic output. These effects are more pronounced in poorer countries and in climate-exposed economic sectors like agriculture, construction, and manufacturing. The development of new technologies that mitigate exposure to heat among workers, combined with better temperature control in the workplace, will be essential to reduce the economic burden of climate change.

Transition to a market economy is accompanied by a period of greater economic uncertainty. Women are likely to suffer substantial disadvantages from this uncertainty compared to men as they are, for example, more likely to lose their job. This not only implies a monetary loss for the entire family, but also degrades female bargaining power within the household, possibly further aggravating their well-being. When intrahousehold inequality—an unequal distribution of resources among family members—exists, female poverty might be significantly larger than what can be deduced using standard household-based poverty measures.

The Covid-19 pandemic has produced unprecedented negative effects on the global economy, affecting both the demand and supply side. Its consequences in terms of job losses have been important in many European countries. A large number of firms have been forced to dismiss at least part of their workforce or to close down all together. Considering that young people are usually penalized more than their adult counterparts during economic crises due to the so-called “last-in-first-out” principle, it is worthwhile to evaluate if the youth will also end up paying the highest price during this pandemic-induced recession.

Private charitable contributions play an essential role in most economies. From a policy perspective, there is concern that comprehensive government spending might crowd out private charitable donations. If perfect crowding out occurs, then every dollar spent by the government will lead to a one-for-one decrease in private spending, leaving the total level of welfare unaltered. Understanding the magnitude and the causes of crowding out is crucial from a policy perspective, as crowding out represents a hidden cost to public spending and can thus have significant consequences for government policies toward public welfare provision.

The rise in the average age of women bearing their first child is a well-established demographic trend in recent decades. Postponed childbearing can have important consequences for the mothers and, at a macro level, for the country in which they live. Research has primarily focused on the effect postponing fertility has on mothers’ labor market outcomes and on the total number of children a woman has in her lifetime. Most research finds that postponing the first birth raises a mother's labor force participation and wages but may have negative effects on overall fertility, especially in the absence of supportive family-friendly policies.

In-plant alliances are plant-specific deviations from sectoral collective agreements related to wages and working time that are intended to hold down labor costs. These agreements enable firm-level reorganizations to respond to an imminent economic crisis or to improve competitiveness. They also encourage social partners to take greater responsibility for employment issues. Both unions and works councils agree to such contracts because they see them as helpful in avoiding severe employment losses. Thus, these alliances substantially unburden public employment policy.

Work-from-home possibilities are lower in developing than in developed countries. Within countries, not all workers have equal chances of transitioning from the usual workplace to work-from-home. Moreover, infrastructure limitations and lack of access to certain services can limit the chances of effectively working from home. Having a home-based job can affect, positively or negatively, work–life balance, levels of job satisfaction and stress, and productivity. The differential chances of working from home may end up increasing the levels of income inequality between workers who can and those who cannot work from home.

Many migrants do not stay in their host countries permanently. On average, 15% of migrants leave their host country in a given year, many of whom will return to their home countries. Temporary migration benefits sending countries through remittances, investment, and skills accumulation. Receiving countries benefit via increases in their prime-working age populations while facing fewer social security obligations. These fiscal benefits must be balanced against lower incentives to integrate and invest in host country specific skills for temporary migrants.

Spending time sleeping not only improves individuals’ well-being, but it can influence employment outcomes and productivity. Sleep can be disrupted by company schedules and deadlines, extended working times, and several individual and household decisions. Labor market regulation and corporate strategies should factor in the immediate effect of insufficient sleep on employee fatigue and cognitive performance, and the associated effects on employment disruption and productivity loss. Sleep can be influenced by “sleep friendly” employment regulations, technology nudges, monetary incentives, and subsidies for sleeping.

Many OECD countries have, or have had, a policy that exempts older unemployed people from the requirement to search for a job. An aging population and low participation by older workers in the labor market increasingly put public finances under strain, and spur calls for policy measures that activate labor force participation by older workers. Introducing job search requirements for older unemployed workers aims to increase their re-employment rates. Abolishing the exemption from job search requirements for the older unemployed has been shown to initiate higher outflow rates from unemployment for them.

Entrepreneurship is essential for a healthy labor market. Recent evidence shows that young businesses (at most ten years old) have, on average, accounted for all of US employment growth over the past few decades. New businesses are especially important for youth employment. However, these businesses tend to borrow a lot, and the credit constraints they face limit their ability to create jobs. Historically, much of the discussion regarding the economic importance of entrepreneurship has focused on small businesses. Empirical evidence increasingly suggests that, among small businesses, those that are young create the most jobs.

From 2000 to 2019, Canada's economy and labor market performed well. Important in this success was a strong resource boom from the late 1990s to 2014. After the boom the economy and labor market adjusted relatively smoothly, with labor and other resources exiting resource-rich regions and moving elsewhere. Strong growth in major export markets (Asia and the US) aided the adjustment. The Covid-19 downturn resulted in an unprecedented decline in employment, and a steep rise in unemployment and non-participation. Despite the severity of the Covid-19 shock, by December 2021 most key measures of labor market activity had returned to pre-pandemic levels.

Standard economic theory suggests that individuals know best how to make themselves happy. Thus, policies designed to encourage more forward-looking behaviors will only reduce people's happiness. Recently, however, economists have explored the role of impatience, especially difficulties with delaying gratification, in several important economic choices. There is strong evidence that some people have trouble following through on investments that best serve their long-term interests. These findings open the door to policies encouraging or requiring more patient behaviors, which would allow people to enjoy the eventual payoff from higher initial investment.

Many experimental studies and surveys have shown that women consistently display more risk-averse behavior than men when confronted with decisions involving risk. These differences in risk preferences, when combined with gender differences in other behavioral traits, such as fondness for competition, have been used to explain important phenomena in labor and financial markets. Recent evidence has challenged this consensus, however, finding gender differences in risk attitudes to be smaller than previously thought and showing greater variation of results depending on the method used to measure risk aversion.

Around ten countries currently use a variant of a national income-contingent loans (ICL) scheme for higher education tuition. Increased international interest in ICL validates an examination of its costs and benefits relative to the traditional financing system, time-based repayment loans (TBRLs). TBRLs exhibit poor economic characteristics for borrowers: namely high repayment burdens (loan repayments as a proportion of income) for the disadvantaged and default. The latter both damages credit reputations and can be associated with high taxpayer subsidies through continuing unpaid debts. ICLs avoid these problems as repayment burdens are capped by design, eliminating default.

The gender wage gap is largely due to men and women holding different kinds of jobs. This job segregation is partly driven by gender differences in careers in corporate hierarchies. Research has shown that the careers of men and women begin to diverge immediately upon entry into the labor market and that subsequent career progress exacerbates the divergence. This divergence of career progress explains a large part of the gender wage gap. Understanding how and why the careers of men and women differ is necessary to design effective policies that can reduce the gender differences in hierarchies.

Developing countries are often seen as unquestionable beneficiaries in the phenomenal rise of global value chains in international trade. Offshoring—the cross-border trade in intermediate goods and services which facilitate country-level specialization in subsets of production tasks—enables an early start in global trade integration even when the requisite technology and knowhow for cost-effective production from scratch to finish are not yet acquired. A growing economics literature suggests a more nuanced view, however. Policymakers should be mindful of issues related to inequality across firms and wages, labor standards, and effects of trade policy.

Remote work and digital collaborations are prevalent in the business world and many employees use digital communication tools routinely in their jobs. Communication shifts from face-to-face meetings to asynchronous formats using text, audio, or video messages. This shift leads to a reduction of information and signals leaders can send and receive. Do classical leadership and communication techniques such as transformational or charismatic leadership signaling still work in those online settings or do leaders have to rely on transactional leadership techniques such as contingent reward and punishment tools in the remote setting?

The IT revolution has had dramatic effects on jobs and the labor market. Many routine manual and cognitive tasks have been automated, replacing workers. By contrast, new technologies complement and create new non-routine cognitive and social tasks, making work in such tasks more productive, and creating new jobs. This has polarized labor markets: while low-skill jobs stagnated, there are fewer and lower-paid jobs for middle-skill workers, and higher pay for high-skill workers, increasing wage inequality. Advances in AI may accelerate computers’ ability to perform cognitive tasks, heightening concerns about future automation of even high-skill jobs.

New Zealand is a small open economy, with large international labor flows and skilled immigrants. After the global financial crisis (GFC) employment took four years to recover, while unemployment took more than a decade to return to pre-crisis levels. Māori, Pasifika, and young workers were worst affected. The Covid-19 pandemic saw employment decline and unemployment rise but this was reversed within a few quarters. However, the long-term impact of the pandemic remains uncertain.

There are a myriad of economic and non-economic forces behind the decision to migrate. Migrants can be “pushed” out of their home countries due to deteriorating economic conditions or political unrest. Conversely, migrants are often “pulled” into destinations that offer high wages, good health care, strong educational systems, or linguistic proximity. In making their decision, individuals compare the net benefits of migration to the costs. By better understanding what forces affect specific migrant flows (e.g. demographic characteristics, migrant networks, and economic conditions), policymakers can set policy to target (or reduce) certain types of migrants.

Many countries experience gender differences, of various magnitudes, in the time devoted to paid work (e.g. market work time) and unpaid work (e.g. housework and childcare). Since household responsibilities influence the participation of women, especially mothers, in the labor market, the unequal sharing of unpaid work, with women bearing the brunt of housework and childcare, is one of the main drivers of gender inequality in the labor market. Understanding the factors behind these gender inequalities is crucial for constructing policies aimed at promoting gender equality and combating gender-based discrimination.

Numerous studies have investigated whether the provision and generosity of parental leave affects the employment and career prospects of women. Parental leave systems typically provide either short unpaid leave mandated by the firm, as in the US, or more generous and universal leave mandated by the government, as in Canada and several European countries. Key economic policy questions include whether, at the macro level, female employment rates have increased due to parental leave policies; and, at the micro level, whether the probability of returning to work and career prospects have increased for mothers after childbirth.

An extensive program of economic liberalization reforms, even when it generates positive outcomes, does not automatically generate support for further reforms. Societies respond with strong support only after experiencing the effects of reversing these reforms (i.e. corruption, inequality of opportunity). This point is illustrated through the example of the post-communist transformation in Eastern Europe and Central Asia—arguably a context where the end point of reforms was never clearly defined, and even successful reforms are now associated with a degree of reform suspicion.

A considerable share of the labor force consists of underemployed part-time workers: employed workers who, for various reasons, are unable to work as much as they would like to. Offering unemployment benefits to part-time unemployed workers is controversial. On the one hand, such benefits can strengthen incentives to take a part-time job rather than remain fully unemployed, thus raising the probability of obtaining at least some employment. On the other hand, these benefits weaken incentives for part-time workers to look for full-time employment. It is also difficult to distinguish people who work part-time by choice from those who do so involuntarily.

High levels of economic inequality may lead to lower economic growth and can have negative social and political impacts. Recent empirical research shows that income and wealth inequalities in Eastern Europe since the fall of socialism increased significantly more than previously suggested. Currently, the average Gini index (a common measure) of inequality in Eastern Europe is about 3 percentage points higher than in the rest of Europe. This rise in inequality was initially driven by privatization, liberalization, and deregulation reforms, and, more recently, has been amplified by technological change and globalization coupled with relatively ungenerous income and wealth redistribution policies.

Employee ownership has attracted growing attention for its potential to improve economic outcomes for companies, workers, and the economy in general, and help reduce inequality. Over 100 studies across many countries indicate that employee ownership is generally linked to better productivity, pay, job stability, and firm survival—though the effects are dispersed and causation is difficult to firmly establish. Free-riding often appears to be overcome by worker co-monitoring and reciprocity. Financial risk is an important concern but is generally minimized by higher pay and job stability among employee owners.

A key element of anti-poverty policy is the accurate identification of poor individuals. However, measuring poverty at the individual level is difficult since consumption data are typically collected at the household level. Per capita measures based on household-level data ignore both inequality within the household and economies of scale in consumption. The collective household model offers an alternative and promising framework to estimate poverty at the individual level while accounting for both inequality within the household and economies of scale in consumption.

In knowledge-based economies, attracting and retaining international students can help expand the skilled workforce. Empirical evidence suggests that open migration policies and labor markets, whereby students can remain in the host country post-study, as well as good quality higher education institutions are crucial for successfully attracting international students. Student migration can positively affect economic growth in both sending and receiving countries, even though migrants themselves reap most of the gains, mainly through higher earnings.

Many workers admit that at times they show up for work even though they feel sick. This behavior, termed “presenteeism,” is puzzling since most workers do not incur financial losses when staying home sick. The various reasons behind presenteeism are person-related (e.g. individuals’ health or job attitude) or work-related (e.g. job demands and constraints on absence from work). Working when sick can have positive and negative consequences for workers’ performance and health, but it also affects co-workers’ well-being and firms’ productivity. There are various strategies as to how firms can address presenteeism.

Gross domestic product (GDP) is the key indicator of the health of an economy and can be easily compared across countries. But it has limitations. GDP tells what is going on today, but does not inform about sustainability of growth. The majority of time is spent in home production, yet the value of this time is not included in GDP. GDP does not measure happiness, so residents can be dissatisfied even when GDP is rising. In addition, GDP does not consider environmental factors, reflect what individuals do outside paid employment, or even measure the current or future potential human capital of a country. Hence, complementary measures may help to show a more comprehensive picture of an economy.

Extreme weather events are increasing in frequency and intensity, threatening lives and livelihoods around the world. Understanding the short- and long-term effects of such events is necessary for crafting optimal policy. The short-term economic impacts of natural disasters can be severe, suggesting that policies that better insure against consumption losses during this time would be beneficial. Longer-term economic impacts are more complex and depend on the characteristics of the affected population and the affected area, changes in migration patterns, and public policy.

In many countries, the wage floors and working conditions set in collective contracts negotiated by a subset of employers and unions are subsequently extended to all employees in an industry. Those extensions ensure common working conditions within the industry, mitigate wage inequality, and reduce gender wage gaps. However, little is known about the so-called bite of collective contracts and whether they limit wage adjustments for all workers. Evidence suggests that collective contract benefits come at the cost of reduced employment levels, though typically only for workers earning close to the wage floors.

There is a widely held belief that older students, by virtue of being more mature and readier to learn at school entry, may have better academic, employment, and earnings outcomes compared to their younger counterparts. There are understated, albeit important, costs to starting school later, however. Compulsory school-attendance laws may allow these same older pupils to drop out of high school earlier, which could adversely impact their employment; entering the workforce later also has implications for lifetime earnings and remittances to governments. Overall, research suggests that school-age entry policies can improve student achievement in the short term, but the long-term impacts are currently not well-understood.

Youth participation in extracurricular activities is associated with a variety of benefits, ranging from higher concurrent academic performance to better labor market outcomes. In particular, these activities provide avenues through which youth can develop the interpersonal and leadership skills that are crucial to succeed as a manager. A lack of opportunity to participate in extracurricular activities for many youths, particularly those from lower-income backgrounds, may have negative consequences for developing the next generation of managers and business leaders.

How migration affects labor markets in receiving countries is well understood, but less is known about how migration affects labor markets in sending countries, particularly the wages of workers who do not emigrate. Most studies find that emigration increases wages in the sending country but only for non-emigrants with substitutable skills similar to those of emigrants; non-emigrants with different (complementary) skills lose. These wage reactions are short-term effects, however. If a country loses many highly educated workers, the economy can become less productive altogether, leading to lower wages for everyone in the long term.

At the national level, it has long been observed that a country's average education level is negatively associated with its total fertility rate. At the household level, it has also been well documented that children's education is negatively associated with the number of children in the family. Do these observations imply a causal relationship between the number of children and the average education level (the quantity–quality trade-off)? A clear answer to this question will help both policymakers and researchers evaluate the total benefit of family planning policies, both policies to lower fertility and policies to boost it.

Immigrants tend to live in clusters within host countries. Does clustering in ethnic enclaves explain the persistent differences in skill, employment rates, and earnings between immigrants and the native population? Empirical studies consistently find that residing in an enclave can increase earnings. While it is ambiguous whether employment probabilities are also affected or whether earnings benefits accrue to all immigrants, irrespective of their skill levels, it is clear that effects are driven by enclave “quality” (in terms of income, education, and employment) rather than enclave size.

In developing and transition economies as much as half the labor force works in the informal sector (or “shadow economy”). Informal firms congest infrastructure and other public services but do not contribute the taxes needed to finance them. Informal workers are unprotected against such negative shocks as ill-health, but for certain groups there can be scarce opportunities to enter the formal sector meaning informal employment is the only feasible option. Reducing informality requires better enforcement, more reasonable regulation, and economic growth.

The labor market disruptions due to the Covid-19 pandemic and lockdowns impacted immigrant workers more severely than native-born workers in the US, Canada, Australia, and most EU countries. Immigrant workers in most of these countries were more vulnerable to the pandemic since they were more likely to be employed in jobs that are not as easy to perform remotely. The labor market recovery for both groups in the US was rapid, and by Fall 2020, the employment gaps between immigrant and native-born workers, both for men and women, had returned to pre-pandemic levels.

France has the second largest population of countries in the EU. Since 2000, the French labor market has undergone substantial changes resulting from striking trends, some of which were catalyzed by the Great Recession and the Covid-19 crisis. The most interesting of these changes have been the massive improvement in the education of the labor force (especially of women), the resilience of employment during recessions, and the dramatic emergence of very-short-term employment contracts (less than a week) and low-income independent contractors, which together have fueled earnings inequality.

Cash transfers are a popular and successful means of tackling household vulnerability and promoting human capital investment. They can also reduce child labor, especially when it is a response to household vulnerability, but their efficacy is very variable. If not properly designed, cash transfers that promote children's education can increase their economic activities in order to pay the additional costs of schooling. The efficacy of cash transfers may also be reduced if the transfers enable investment in productive assets that boost the returns to child labor. The impact of cash transfers must thus be assessed as part of the whole incentive system faced by the household.

Female labor force participation is mainly driven by the value of their market wages versus the value of their non-market time. Labor force participation varies considerably across countries. To understand this international variation, it is important to further consider differences across countries in institutions, non-economic factors such as cultural norms, and public policies. Such differences provide important insights into what actions countries might take to further increase women's participation in the labor market.

The number of refugees has increased worldwide, and about half of them are children and youth. These refugee children arrive in resettlement countries with a unique set of challenges caused by, for instance, extreme stress and trauma that call for specific policies to address their needs. Yet, the long-term effect of refugee status on newcomer children's economic trajectories varies by country of origin, signaling the need for effective resettlement support and initiatives to tackle broader systemic barriers for newcomer children, beyond refugees. Such findings challenge the commonly held notion of refugees as a distinctive, relatively homogeneous group with similar trajectories.

A growing number of firms offer compensation packages that link pay to performance. The aim is to motivate workers to be more efficient while also increasing their attachment to the company, thereby reducing turnover and absenteeism. The effects of performance-related pay on productivity depend on the scheme type and design, with individual incentives showing the largest effect. Governments often offer tax breaks and financial incentives to promote performance-related pay, though their desirability has been questioned due to large deadweight losses involved. The diffusion of remote work will increase the relevance of performance-related pay.

Recent research has tried to quantify how firms contribute to the immigrant–native earnings gap. Findings from several countries show that around 20% of the gap is due to firm policies that lead to a systematic underrepresentation of immigrants at higher-paying firms. Results also show that some of the closing of the gap over time is attributable to the reallocation of immigrants toward higher-paying employers. This pattern is especially pronounced for immigrants coming from disadvantaged countries, who face several barriers at initial entry, including language difficulties and lack of recognition of their educational credentials.

Recessions are complex events that affect personal health and behavior via various potentially opposing mechanisms. While recessions are known to have negative effects on mental health and lead to an increase in suicides, it has been proven that they reduce mortality rates. A general health policy agenda in relation to recessions remains ambiguous due to the lack of consistency between different individual- and country-level approaches. However, aggregate regional patterns provide valuable information, and local social planners could use them to design region-specific policy responses to mitigate the negative health effects caused by recessions.

Many countries have enacted legislation over the past few decades making divorce easier. Some countries have legalized divorce where it had previously been banned, and many have eased the conditions required for a divorce, such as allowing unilateral divorce (both spouses do not have to agree on the divorce). Divorce laws can regulate the grounds for divorce, division of property, child custody, and child support or maintenance payments. Reforms can have a range of social effects beyond increasing the divorce rate. They can influence female labor supply, marriage and fertility rates, child well-being, household saving, and even domestic violence and crime.

Time plays an important role in both the design and interpretation of evaluation studies of training programs. While the start and duration of a training program are closely linked to the evolution of job opportunities, the impact of training programs in the short and longer term changes over time. Neglecting these “dynamics” could lead to an unduly negative assessment of the effects of certain training schemes. Therefore, a better understanding of the dynamic relationship between different types of training and their respective labor market outcomes is essential for a better design and interpretation of evaluation studies.

Return migration can have multiple benefits. It allows migrants who have accumulated savings abroad to ease credit constraints at home and set up a business. Also, emigrants from low- and middle-income countries who have invested in their human capital may earn higher wages when they return. However, whether the home country benefits from return migrants depends on the migrant's success in accumulating savings and human capital and on the home country's ability to make use of returnees’ skills and investment. To benefit from returnees, home countries need policies that encourage returnees’ investment and labor market reintegration.

Differences in labor market outcomes for women and men are highly persistent. Apart from discrimination, one frequently mentioned explanation could be differences in the attitude toward competition for both genders. Abundant empirical evidence indicates that multiple influences shape attitudes toward competition during different periods of the life cycle. Gender differences in competitiveness will not only influence outcomes during working age, but also during early childhood education. In order to reduce the gender gap in educational and labor market outcomes, it is crucial to understand when and why gender gaps in competitiveness arise and to study their consequences.

Unemployment not only causes material hardship but can also affect an individual's sense of identity (i.e. their perception of belonging to a specific social group) and, consequently, feelings of personal happiness and subjective well-being. Labor market policies designed to help the unemployed may not overcome their misery: wage subsidies can be stigmatizing, measures that require some work or attendance for training from those receiving benefits (workfare) may not provide the intended incentives, and a combination of an unregulated labor market and policy measures that bring people who became unemployed quickly back to work (flexicurity) may increase uncertainty. Policies aimed at bringing people back to work should thus take the subjective well-being of the affected persons more into consideration.

Parents now engage in much more intensive parenting styles compared to a few decades ago. Today’s parents supervise their children more closely, spend more time interacting with them, help much more with homework, and place more emphasis on educational achievement. More intensive parenting has also led to more unequal parenting: highly educated parents with high incomes have increased their parenting investments the most, leading to a growing “parenting gap” in society. These trends can contribute to declining social mobility and further exacerbate rising inequality, which raises the question of how policymakers should respond.

As the largest economy in the world, the US labor market is crucial to the economic well-being of citizens worldwide as well as, of course, that of its own citizens. Since 2000 the US labor market has undergone substantial changes, reflecting the Great Recession and the Covid Recession, but also resulting from some striking trends. Most interesting have been a remarkable drop in the labor force participation rate, reversing a nearly 50-year trend; the full recovery of unemployment after 2010 and its skyrocketing in 2020; and the little-known continuing growth in post-inflation average earnings.

Migration policies need to consider how immigration affects investment behavior and productivity, and how these effects vary with the type of migration. College-educated immigrants may do more to stimulate foreign direct investment and research and development than low-skilled immigrants, and productivity effects would be expected to be highest for immigrants in scientific and engineering fields. By raising the demand for housing, immigration also spurs residential investment. However, residential investment is unlikely to expand enough to prevent housing costs from rising, which has important distributional implications.

Ever since the major inflow of refugees (the “refugee crisis”) in 2015 and 2016, there has been heated debate about the appropriate distribution of refugees in the EU. Current policies revolve around mandatory quotas, which disregard the preferences of EU members and refugees alike. This problem can be addressed with two market mechanisms. First, tradable quotas minimize the cost of asylum provision for host countries. Second, a matching system gives refugees more discretion over where they are sheltered. While this proposal is theoretically appealing, it has yet to be tested in practice.

In transition economies, a significant number of companies reduce their tax and social contributions by paying their staff an official salary, described in a registered formal employment agreement, and an extra, undeclared “envelope wage,” via a verbal unwritten agreement. The consequences include a loss of government income and a lack of fair play for lawful companies. For employees, accepting under-reported wages reduces their access to credit and their social protections. Addressing this issue will help increase the quality of working conditions, strengthen trade unions, and reduce unfair competition.

Minimum wage increases are not an effective mechanism for reducing poverty. And there is little causal evidence that they do so. Most workers who gain from minimum wage increases do not live in poor (or near-poor) families, while some who do live in poor families lose their job as a result of such increases. The earned income tax credit is an effective way to reduce poverty. It raises only the after-tax wage rates of workers in low- and moderate-income families, the tax credit increases with the number of dependent children, and evidence shows that it increases labor force participation and employment in these families.

Ample empirical evidence links adverse conditions during early childhood (the period from conception to age five) to worse health outcomes and lower academic achievement in adulthood. Can early-life medical care and public health interventions ameliorate these effects? Recent research suggests that both types of interventions may benefit not only child health but also long-term educational outcomes. In some cases, the effects of interventions may spillover to other family members. These findings can be used to design policies that improve long-term outcomes and reduce economic inequality.

Labor market institutions that may weaken workers’ bargaining leverage have received increased scrutiny in recent years. One example is noncompete agreements, which prevent workers from freely moving across employers, potentially weakening earnings growth. New data sources and empirical evidence have led policymakers to consider sharp restrictions on their use, especially among lower-income workers. These restrictions take many different forms, each of which has unique tradeoffs between the desire to protect workers while allowing firms to use noncompetes in cases where they may create social value.

Employers are steadily increasing their reliance on technology when recruiting. On the one hand, this technology enables the wide dissemination of information and the management of large quantities of data at a relatively low cost. On the other hand, it introduces new costs and risks. The ease with which information can be shared, for example, can lead to its unauthorized use and obsolescence. Recruiting technologies are also susceptible to misuse and to biases built into their underlying algorithms. Better understanding of these trade-offs can inform government policies aiming to reduce search frictions in the labor market.

Eastern European countries, particularly former Soviet Union economies, traditionally have the highest rates of alcohol consumption in the world. Consequently, they also have some of the highest male mortality rates in the world. Regulation can be effective in significantly decreasing excessive drinking and its related negative effects, such as low labor productivity and high rates of mortality. Understanding the consequences of specific regulatory measures and what tools should be used to combat excessive alcohol consumption is essential for designing effective policies.

The labor market position of older workers is cause for concern in many industrialized countries. Rapid population aging is challenging pension systems. The recent economic crisis has forced many older adults out of the workforce, into either pre-retirement or non-employment. Encouraging people to work longer and fostering the employability of older workers have become priorities for policymakers. Training specifically designed for older workers might help attain these goals, since it may refresh human capital and reduce the pay–productivity gap. Training older workers might also benefit employers and society as a whole.

Corporate income taxation influences the quantity and type of entrepreneurship, which in turn affects economic development. Empirical evidence shows that higher corporate income tax rates reduce business density and entrepreneurship entry rates and increase the capital size of new firms. The progressivity of tax rates increases entrepreneurship entry rates, whereas highly complex tax codes reduce them. Policymakers should understand the effects and underlying mechanisms that determine how corporate income taxation influences entrepreneurship in order to provide a favorable business environment.

High risk of poverty and low employment rates are widespread among low-skilled groups, especially in the case of some household compositions (e.g. single mothers). “Making-work-pay” policies have been advocated for and implemented to address these issues. They alleviate the above-mentioned problems without providing a disincentive to work. However, do they deliver on their promises? If they do reduce poverty and enhance employment, is it possible to determine their effects on indicators of well-being, such as mental health and life satisfaction, or on the acquisition of human capital?

Guest worker programs allow migrants to work abroad legally, and offer benefits to workers, firms, and nations. Guest workers are typically authorized to work only in specific labor markets, and are sponsored by, and must work for, a specific firm, making it difficult for guest workers to switch employers. Critics argue that the programs harm host country citizens and permanent residents (“existing workers”), and allow employers to exploit and abuse vulnerable foreign-born workers. Labor market institutions, competitive pressures, and firm strategy contribute to the effects of migration that occur through guest worker programs.

Income inequality has been on the rise in many countries. Is this bad? One way to decide is to look at the degree of change in incomes across generations (intergenerational mobility) and, more generally, at the extent to which income differences among individuals are traceable to their social origins. Inequalities that reflect factors largely out of an individual’s control—such as parents’ education, local schools, and communities—require attention in order to reduce income inequality. Evidence shows a negative association between income inequality and intergenerational mobility, and a positive relationship between mobility and economic performance.

Countries have adopted a variety of legalization programs to address unauthorized immigration. Research in the US finds improved labor market outcomes for newly authorized immigrants. Findings are more mixed for European and Latin American countries where informal labor markets play a large role and programs are often small scale. Despite unclear labor market outcomes and mixed public support, legalization will likely continue to be widely used. Comprehensive legislation can address the complex nature of legalization on immigrants and on native-born residents.

Many countries are experiencing increasing inflows of immigrant students. This raises concerns that having a large share of students for whom the host country language is not their first language may have detrimental effects on the educational outcomes of native children. However, the evidence is mixed, with some studies finding negative effects, and others finding no effects. Whether higher concentrations of immigrant students have an effect on native students differs across countries according to factors such as organization of the school system and the type of immigrants.

Higher inequality reduces capital accumulation and increases the informal economy, which creates additional employment opportunities for low-skilled and deprived people. As a result, informal employment leads to beneficial effects on income distribution by providing sources of income for unemployed and marginalized workers. Despite this positive feedback, informality raises problems for public finances and biases official statistics, reducing the effectiveness of redistributive policies. Policymakers should consider the links between inequality and informality because badly designed informality-reducing policies may increase inequality.

Low-wage employment has become an important feature of the labor market and a controversial topic for debate in many countries. How to interpret the prominence of low-paid jobs and whether they are beneficial to workers or society is still an open question. The answer depends on whether low-paid jobs are largely transitory and serve as stepping stones to higher-paid employment, whether they become persistent, or whether they result in repeated unemployment. The empirical evidence is mixed, pointing to both stepping-stone effects and “scarring” effects (i.e. long-lasting detrimental effects) of low-paid work.

In Europe, about one in eight people of working age report having a disability; that is, a long-term limiting health condition. Despite the introduction of a range of legislative and policy initiatives designed to eliminate discrimination and facilitate retention of and entry into work, disability is associated with substantial and enduring labor market disadvantage in many countries. Identifying the reasons for this is complex, but critical to determine effective policy solutions that reduce the extent, and social and economic costs, of disability-related disadvantage.

In today's globalized world, people are increasingly mobile and often need to communicate across different languages. Learning a new language is an investment in human capital. Migrants must learn the language of their destination country, but even non-migrants must often learn other languages if their work involves communicating with foreigners. Economic studies have shown that fluency in a dominant language is important to economic success and increases economic efficiency. However, maintaining linguistic diversity also has value since language is also an expression of people's culture.

Higher labor costs (higher wage rates and employee benefits) make workers better off, but they can reduce companies’ profits, the number of jobs, and the hours each person works. The minimum wage, overtime pay, payroll taxes, and hiring subsidies are just a few of the policies that affect labor costs. Policies that increase labor costs can substantially affect both employment and hours, in individual companies as well as in the overall economy.

Statistical models can help public employment services to identify factors associated with long-term unemployment and to identify at-risk groups. Such profiling models will likely become more prominent as increasing availability of big data combined with new machine learning techniques improve their predictive power. However, to achieve the best results, a continuous dialogue between data analysts, policymakers, and case workers is key. Indeed, when developing and implementing such tools, normative decisions are required. Profiling practices can misclassify many individuals, and they can reinforce but also prevent existing patterns of discrimination.

Anti-discrimination policies play an important role in public discussions. However, identifying discriminatory practices in the labor market is not an easy task. Correspondence testing provides a credible way to reveal discrimination in hiring and provide hard facts for policies, and it has provided evidence of discrimination in hiring across almost all continents except Africa. The method involves sending matched pairs of identical job applications to employers posting jobs—the only difference being a characteristic that signals membership to a group.
