Do schooling reforms improve long-term health?
It is difficult to find consistent evidence that schooling reforms provide health benefits

A statistical association between more education and better health outcomes has long been observed, but in the absence of experimental data researchers have struggled to find a causal effect. Schooling reforms such as raising school leaving age, which have been enacted in many countries, can be viewed as a form of natural experiment and provide a possible method of identifying such an effect. However, the balance of evidence so far is that these reforms have had little impact on long-term health. Thus, policymakers should be cautious before anticipating a health effect when introducing reforms of this nature.

  • Promoting internal whistleblowing in organizations

    Internal whistleblowing results in reduced fraud, a better brand image, and a higher overall performance

    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.

  • Fertility decisions and alternative types of childcare Updated

    Relative costs and family characteristics determine the effectiveness of different forms of childcare

    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 economy in industrial countries Updated

    Reducing the size of the shadow economy requires reducing its attractiveness while improving official institutions

    Dominik H. Enste , October 2024
    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 and their impact on jobs and economic growth Updated

    Productive entrepreneurs can invigorate the economy by creating jobs and new technologies, and increasing productivity

    Alexander S. Kritikos , October 2024

    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.

  • Using instrumental variables to establish causality Updated

    Even with observational data, causality can be recovered with the help of instrumental variables estimation

    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.

  • Estimating the return to schooling using the Mincer equation Updated

    The Mincer equation gives comparable estimates of the average monetary Returns of one additional year of education

    Harry Anthony Patrinos , August 2024
    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.

  • Does increasing the minimum wage reduce poverty in developing countries? Updated

    Whether raising minimum wages reduces—or increases—poverty depends on the characteristics of the labor market and Households

    T. H. Gindling , August 2024
    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.

  • Sexual harassment in the workplace Updated

    The #MeToo movement brought heightened attention to sexual harassment and a search for new approaches to combat it

    Joni Hersch , July 2024
    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.

  • Unemployment benefits and unemployment Updated

    The challenge of unemployment benefits is to protect workers while minimizing undesirable side effects

    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.

  • The effects of public sector employment on the economy Updated

    The size and wage level of the public sector affect overall employment volatility and the economy

    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.

  • Public or private job placement services — Are private ones more effective? Updated

    Outsourcing to the private sector can only be effective if the service quality can be contracted on

    Gesine Stephan , May 2024
    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.

  • Entrepreneurship for the poor in developing countries Updated

    Well-designed entrepreneurship programs show promise for improving earnings and livelihoods of poor workers

    Yoonyoung Cho , May 2024
    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.

  • The labor market in Brazil, 2001–2022 Updated

    Brazil’s long-lasting recession has hurt the poor and has reversed inequality trends

    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.

  • The importance of informal learning at work Updated

    On-the-job learning is more important for workers’ human capital development than formal training

    Andries De Grip , March 2024
    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.

  • Compensating displaced workers Updated

    Job displacement is a serious earnings risk and the displaced are typically poorly insured

    Donald O. Parsons , February 2024
    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.

  • Trans people, well-being, and labor market outcomes Updated

    Transitioning across gender is related to greater life and job satisfaction but also affects acceptance in one’s society

    Nick Drydakis , January 2024
    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.

  • Labor market institutions and policies in old and new EU members Updated

    After three recessions, a new emphasis on the importance of collective institutions and social dialogue is emerging

    Riccardo Rovelli , January 2024
    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: Career pathway or dire straits? Updated

    Moonlighting responds to economic needs, but can generate new skills and careers

    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.

  • Rethinking the skills gap Updated

    Better understanding of skills mismatch is essential to finding effective policy options

    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.

  • Climate change, natural disasters, and migration Updated

    The relationship between climate change, natural disasters, and migration is not straightforward and presents many complexities

    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.

  • Employers and the gender wage gap

    Sorting across workplaces, and unequal rewards within them, are major causes of the gender wage gap

    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.

  • How are minimum wages set? Updated

    Countries set minimum wages in different ways, and some countries set different wages for different groups of workers

    Richard Dickens , September 2023
    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.

  • Should the earned income tax credit rise for childless adults? Updated

    The earned income tax credit boosts income and work effort among low-income parents, especially single mothers, and has contributed to the steep rise in employment among single mothers in the 1990s.

    Harry J. Holzer , September 2023
    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.

  • Do institutions matter for entrepreneurial development? Updated

    In post-Soviet countries, well-functioning institutions are needed to foster productive entrepreneurial development and growth

    Ruta Aidis , August 2023
    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.

  • How should job displacement wage losses be insured? Updated

    Wage losses upon re-employment can seriously harm long-tenured displaced workers if they are not properly insured

    Donald O. Parsons , July 2023
    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.

  • Instruction time and educational outcomes

    The quality of instruction and the activities it replaces determine the success of increased instruction time

    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.

  • How to support adult caregivers?

    Caregiving for older adults is detrimental to caregivers’ well-being and requires policy interventions to support them

    Joan Costa-Font , June 2023
    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.

  • The widespread impacts of remittance flows Updated

    Remittances have the potential to lift developing economies

    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.

  • Unions and investment in intangible capital Updated

    When workers and firms cannot commit to long-term contracts and capital investments are sunk, union power can reduce investment

    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.

  • Eliminating discrimination in hiring isn’t enough

    Firms interested in workplace diversity should consider the post-hiring stage and why some minority employees choose to leave

    Mackenzie Alston , May 2023
    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.

  • Maternity leave versus early childcare—What are the long-term consequences for children? Updated

    Despite increasingly generous parental leave schemes their advantages over subsidized childcare remain unclear

    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.

  • Female education and its impact on fertility Updated

    Additional female educational attainment generally lowers fertility, but the relationship is complex

    Jungho Kim , May 2023
    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.

  • The Danish labor market, 2000–2022 Updated

    The Danish flexicurity model has proven its resilience to large shocks, with favorable overall labor market performance

    Torben M. Andersen , April 2023
    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.

  • Trust in management in organizations

    Employee trust in their managers allows a firm to delegate decision-making, aiding both productivity and profitability

    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.

    Leora Klapper , April 2023
    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.

  • Performance measures and worker productivity Updated

    Choosing the right performance measures can inform and improve decision-making in policy and management

    Jan Sauermann , April 2023
    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.
