Skills and training programs

Economists have long believed that firms will not pay to develop occupational skills that workers could use in other, often competing, firms. Researchers now recognize that firms that invest in apprenticeship training generally reap good returns. Evidence indicates that financial returns to firms vary. Some recoup their investment within the apprenticeship period, while others see their investment pay off only after accounting for reduced turnover, recruitment, and initial training costs. Generally, the first year of apprenticeships involves significant costs, but subsequently, the apprentice's contributions exceed his/her wages and supervisory costs. Most participating firms view apprenticeships as offering certainty that all workers have the same high level of expertise and ensuring an adequate supply of well-trained workers to cover sudden increases in demand and to fill leadership positions.

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.

As the number of secondary school graduates rises, many developing countries expand the supply of public and private universities or face pressure to do so. However, several factors point to the need for caution, including weak job markets, low-quality university programs, and job–education mismatches. More university graduates in this context could exacerbate unemployment, underemployment, and overeducation of professionals. Whether governments should regulate the quantity or quality of university programs, however, depends on the specific combination of factors in each country.

Productivity differences across firms and countries are surprisingly large and persistent. Recent research reveals that the country-level distributions of productivity and quality of management are strikingly similar, suggesting that management practices may play a key role in the determination of worker and firm productivity. Understanding the causal impacts of these practices on productivity and the effectiveness of various management interventions is thus of primary policy interest.

Developing countries have long been struggling to fight informality, focusing on instruments such as labor legislation enforcement, temporary contracts, and changes in taxes imposed on small firms. However, improvements in the labor force’s schooling and skill level may be more effective in reducing informality in the long term. Higher-skilled workers are typically employed by larger firms that use more capital, and that are more likely to be formal. Additionally, when skilled and unskilled workers are complementary in production, unskilled workers’ wages tend to increase, adding yet another force toward reducing informality.

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.

The rural non-farm sector plays an important role in diversifying income for rural households in developing countries and has the potential to emerge as a major source of employment. In some cases it has outgrown the agricultural sector, in part due to the expansion of credit through microfinance institutions that are supported by governments, donor agencies, and businesses. However, future expansion of the rural non-farm sector requires increased flexibility in credit contracts, as well as decreasing the cost of credit and the delivery of complementary inputs, e.g. skills training.

Teachers are perhaps the most important determinant of education quality. But what makes a teacher effective? Developing countries expend substantial resources on certifying teachers and retaining those who become certified; moreover, policymakers and aid donors prioritize increasing the prevalence of certified teachers. Yet there is little evidence that certification improves student outcomes. In fact, augmenting a school's teaching corps with contract teachers hired outside the civil service and without formal qualifications may be more effective in boosting student performance.

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.

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.
