Schooling and higher education

In addition to the traditional education system targeting children and youth, one potentially important vehicle to improve literacy and numeracy skills is adult literacy programs (ALPs). In many developing countries, however, these programs do not seem to achieve these hoped for, ex ante, objectives and have therefore received less attention, if not been largely abandoned, in recent years. But, evidence shows that ALPs do affect other important socio-economic outcomes such as health, household income, and labor market participation by enhancing participants’ health knowledge and income-generating activities.

Developing countries often face two well-known structural problems: high youth unemployment and high inequality. In recent decades, policymakers have increased the share of government spending on education in developing countries to address both of these issues. The empirical literature offers mixed results on which type of education is most suitable to improve gainful employment and reduce inequality: is it primary, secondary, or tertiary education? Investigating recent literature on the returns to education in selected developing countries in Africa can help to answer this question.

Since the 1970s, many countries have established free or highly subsidized education for all preschool children in the hope of improving children’s learning and socio-economic life chances and encouraging mothers to join the labor force. Evaluations reveal that these policies can increase maternal employment in the short term and may continue to do so even after the child is no longer in preschool by enabling mothers to gain more job skills and increase their attachment to the labor force. However, their effectiveness depends on the policy design, the country context, and the characteristics of mothers of preschoolers.

Reaching the policy goal of improving student achieve­ment by adding resources to the school system has often proven elusive. By contrast, ample evidence indicates that central exit exams constitute an important feature of a school system’s institutional framework, which can hold students, teachers, schools, and administrators accountable for student outcomes. While critics point to issues such as teaching test-only skills, which may leave students ill-prepared for the real world, the evidence does not bear this out. Overall, central exams are related to better student achievement, favorable labor market outcomes, and higher economic growth.

Numerous economic studies have considered the relationship between class size and student achievement, the majority of which have focused on elementary schools in the US and Europe. While the general finding is that smaller classes are associated with increased student achievement, a few high-quality studies find no relationship. Further, empirical research on the costs and benefits of smaller classes concludes that other education policies, such as tutoring, early childhood programs, or improving teacher quality would be better investments.

Formal schooling increases earnings and provides other individual benefits. However, societal benefits of education may exceed individual benefits. Research finds that higher average education levels in an area are correlated with higher earnings, even for local residents with minimal education. Science, technology, engineering, and mathematics (STEM) graduates appear to generate especially strong external effects, due to their role in stimulating innovation and economic growth. Several strategies to test for causality find human capital externalities do exist.

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.

Many countries around the world are making substantial and increasing public investments in children by providing resources for schooling from early years through to adolescence. Recent research has looked at how parents respond to children’s schooling opportunities, highlighting that public inputs can alternatively encourage or crowd out parental inputs. Most evidence finds that parents reduce their own efforts as schooling improves, dampening the efficiency of government expenditure. Policymakers may thus want to focus government provision on schooling inputs that are less easily substituted.
