  • How does grandparent childcare affect labor supply?

    Childcare provided by grandparents helps young working mothers, but reduces the labor supply of older women

    Giulio Zanella, March 2017
    Older people in developed countries are living longer and healthier lives. A prolonged and healthy mature period of life is often associated with continued and active participation in the labor market. At the same time, active grandparents can offer their working offspring a free, flexible, and reliable source of childcare. However, while grandparent-provided childcare helps young parents (especially young mothers) overcome the negative effects of child rearing on their labor market participation, it can sometimes conflict with the objective of providing additional income through employment for older workers, most notably older women.

  • Does broadband infrastructure boost employment?

    Broadband infrastructure has differing effects on workers of different skills

    Oliver Falck, March 2017
    Broadband infrastructure enables fast access to the internet, which, evidence suggests, has significant effects on economic growth. However, labor market related issues have not received as much consideration. These include quantifying employment effects of broadband infrastructure roll-out and questions about who exactly are the winners and losers in the labor market, and whether skills in information and communication technologies (ICT) are reflected in labor market outcomes such as wages. Understanding these complementary issues allows for policy conclusions that go beyond simply encouraging the subsidization of broadband internet infrastructure.

  • For long-term economic development, only skills matter

    Economic growth determines a nation’s long-term economic well-being and crucially depends on skills

    Eric A. Hanushek, March 2017
    Politicians typically focus on short-term economic issues; but, a nation’s long-term economic well-being is directly linked to its rate of economic growth. In turn, its growth rate is directly linked to the economically relevant skills of its population. Until recently, however, economists have found it hard to confirm this through empirical analysis because of difficulties in measuring the skills of different societies. International tests of mathematics and science achievement now offer reliable measures of a population’s relevant cognitive skills.

  • Do payroll tax cuts boost formal jobs in developing countries?

    Payroll tax cuts in developing economies might be beneficial to the formal sector, even when the informal sector is large

    Carmen Pagés, March 2017
    Informal employment accounts for more than half of total employment in Latin America and the Caribbean, and an even higher percentage in Africa and South Asia. It is associated with lack of social insurance, low tax collection, and low productivity jobs. Lowering payroll taxes is a potential lever to increase formal employment and extend social insurance coverage among the labor force. However, the effects of tax cuts vary across countries, often resulting in large wage shifts but relatively small employment effects. Cutting payroll taxes requires levying other taxes to compensate for lost revenue, which may be difficult in developing economies.

  • Identifying and measuring economic discrimination

    Using decomposition methods helps measure both the amount and source of economic discrimination between groups

    Differences in wages between men and women, white and black workers, or any two distinct groups are a controversial feature of the labor market, raising concern about discrimination by employers. Decomposition methods shed light on those differences by separating them into: (i) composition effects, which are explained by differences in the distribution of observable variables, e.g. education level; and (ii) structural effects, which are explained by differences in the returns to observable and unobservable variables. Often, a significant structural effect, such as different returns to education, can be indicative of discrimination.

  • Female poverty and intrahousehold inequality in transition economies

    An unequal distribution of resources within the family is a special concern for female poverty

    Luca Piccoli, March 2017
    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 intra-household 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.

  • Can firms oversee more workers with fewer managers?

    Firms need to tailor their allocation of talent and responsibility, and their managerial structure, to fit their competitive situation

    Valerie Smeets, February 2017
    Managers are supervising more and more workers, and firms are getting flatter. However, not all firms have been keen on increasing the number of subordinates that their bosses manage (referred to as the “span of control” in human resource management), contending that there are limits to leveraging managerial ability. The diversity of firms’ organizational structure suggests that no universal rule can be applied. Identifying the factors behind the choice of firms’ internal organization is crucial and will help firms properly design their hierarchy and efficiently allocate scarce managerial resources within the organization.

  • Do institutions matter for entrepreneurial development?

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

    Ruta Aidis, February 2017
    Supportive institutional environments help build the foundations for innovative and productive entrepreneurship. A few post-Soviet countries have benefitted from international integration through EU membership, which enabled the development of democracy and free market principles. However, many post-Soviet economies continue to face high levels of corruption, complex business regulations, weak rule of law and uncertain property rights. For them, international integration can provide the needed support to push through unpopular yet necessary stages of the reform process.

  • Does religiosity explain economic outcomes?

    Understanding religiosity is crucial to informed policy making

    Olga Popova, February 2017
    Most religions in transition economies were marginalized by their former communist regimes. Today, some of these countries are experiencing a revival of religiosity, while others are prone to secularization. Religious norms affect individual decision making with respect to human capital investment, economic reforms, marital stability, employment, and other contexts. This implies that the interests of both religious and non-religious communities may differ and must be taken into account when designing and implementing economic policies, which is a challenge for policymakers.

  • Using linear regression to establish empirical relationships

    Linear regression is a powerful tool for estimating the relationship between one variable and a set of other variables

    Marno Verbeek, February 2017
    Linear regression is a powerful tool for investigating the relationships between multiple variables by relating one variable to a set of variables. It can identify the effect of one variable while adjusting for other observable differences. For example, it can analyze how wages relate to gender, after controlling for differences in background characteristics such as education and experience. A linear regression model is typically estimated by ordinary least squares, which minimizes the differences between the observed sample values and the fitted values from the model. Multiple tools are available to evaluate the model.
