Economic returns to education

In many transition countries, the collapse of communism ushered in language reforms to adapt to the newfound independence from the Soviet Union and openness to the rest of the world. Such reforms may have implications for individuals’ economic opportunities, since foreign language proficiency may enhance or signal productivity in the labor market. Recent empirical evidence documents positive labor market returns to English language skills in transition countries. However, Russian language proficiency also remains economically valuable, and nationalist language policies may lead to future loss of economic opportunities.

The level of financial literacy in developed countries is low and contributes to growing wealth inequality. Benefits from increasing the level of financial literacy include more effective saving for retirement and better debt management. However, there are significant costs in terms of time and money of acquiring financial literacy, which imply that the net value of acquiring financial literacy is heterogeneous in the population. This potentially makes designing effective interventions difficult.

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’ wage-setting practices, garners comparatively little policy attention.

Compulsory schooling laws are a common policy tool to achieve greater participation in education, particularly from marginalized groups. Raising the compulsory schooling requirement forces students to remain in school which, on balance, is good for them in terms of labor market outcomes such as earnings. But the usefulness of this approach rests with how the laws affect the distribution of years of schooling, and the wider benefits of the increase in schooling. There is also evidence that such a policy has an intergenerational impact, which can help address persistence in poverty across generations.

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.

The quantity and quality of educational investment matter for labor market outcomes such as earnings and employment. Yet, not everyone knows this, and navigating the education system can be extremely complex both for students and their parents. A growing economic literature has begun to test whether interventions designed to improve information about the costs and benefits of education and application processes have an effect on students’ behavior. So far, findings have been mixed, although the positive findings arising from some very carefully targeted interventions give cause for hope.

Universal completion of secondary education by 2030 is among the targets set by the United Nations’ Sustainable Development Goals. Higher expected adult wages traced to schooling may play a major role in reaching this target as they are predicted to induce increased school enrollment for children whose families wish to optimally invest in their children’s future. However, low incomes and the obligation to meet immediate needs may forestall such investment. Studies suggest that school enrollment in developing countries is positively correlated with higher expected future wages, but poor families continue to under-enroll their children.

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.

Laws on age at school entry affect student achievement and often change for a number of reasons. Older students are more mature and ready to learn. This can have positive impacts on academic, employment, and earnings outcomes. The costs of holding children back include another year of childcare expenses or income forgone by the caregiver parent. Entering the workforce one year later also has implications for lifetime earnings and remittances to governments. School-entry policies could be a useful tool in increasing student achievement, but the short- and long-term impacts need to be better understood.

Policymakers in many OECD countries are increasingly concerned about high and rising inequality. Much of the evidence (as far back as Adam Smith’s ) points to the importance of skills in tackling wage inequality. Yet a recent strand of the research argues that (cognitive) skills explain little of the cross-country differences in wage inequality. Does this challenge the received wisdom on the relationship between skills and wage inequality? No, because this recent research fails to account for the fact that the price of skill (and thus wage inequality) is determined to a large extent by the match of skill supply and demand.
