Directly unproductive schooling: How country characteristics affect the impact of schooling on growth

The rapid rise in schooling in developing countries in recent decades has been dramatic. However, many cross-country regression analyses of the impact of schooling on economic growth find low and insignificant coefficients. This empirical ‘puzzle’ contrasts with theoretical arguments that schooling, through raising human capital, should raise income levels. This paper argues that poor results are to be expected when regression samples include countries that vary greatly in their ability to use schooling productively. Data on corruption, the black market premium on foreign exchange and the extent of the brain drain for developing countries are used as indicators of an economy's productive use of schooling. Regression analysis shows that the impact of schooling on economic growth is substantially higher in countries that are adjudged to use schooling productively.     

Cronyism and education performance

Recent research suggests that some countries may be unable to use productively their schooling output because of the scope of cronyism or corruption. We investigate further and demonstrate that, in a stylised model, cronyism in the labour market, (e.g. the ability to exert influence to gain high wage positions without merit), may impact heavily on the relationship between schooling inputs and cognitive skills, due to incentive effects. We then use a two-stage DEA approach to identify factors affecting inefficiency in education performance of OECD countries, as measured by PISA scores. Along with other well known factors, a proxy measure for cronyism from the World Value Survey, explains a substantial fraction of the inefficiency. This result suggests that, as in our model, in the presence of cronyism, incentives to cognitive skills acquisition are dampened. The best way to improve education performance may be to increase transparency in labour access.     

The effect of fair trade affiliation on child schooling: evidence from a sample of Chilean honey producers

We evaluate the impact of Fair Trade (FT) affiliation on child schooling within a sample of Chilean honey producers with a retrospective panel data approach. From a theoretical point of view, we argue that FT should have a positive effect on child schooling since it generates a short-run pure income effect together with a medium-run productivity effect on both adult and child wages. On the other hand, because of the higher productivity generated by the medium-run effect, the opportunity cost of child education increases if they work with their parents. The direction of the impact of FT affiliation on child schooling is therefore uncertain and requires empirical testing. Our econometric findings document a positive and significant impact of affiliation years on child schooling after controlling for endogeneity and heterogeneity between the treatment and control sample.     

Long-term impact of investments in early schooling — Empirical evidence from rural Ethiopia

We examine the cumulative impact of early schooling investments on later schooling outcomes using enrollment status and relative grade attainment as short-run and long-run measures of schooling. Using a child-level longitudinal data set from rural Ethiopia, we estimate a dynamic conditional schooling demand function where the coefficient estimate on the lagged dependent variable captures the impact of all previous period schooling inputs and resources. We find that a child who is enrolled in the prior period is 33 percentage points more likely to be enrolled currently. These lagged effects are stronger for girls and for children from higher income households.     

Children's schooling in Nicaragua: What is the link between educational achievement,borrowing, and gender?

The impact of credit has been widely studied, and yet little is known about the effect of formal versus informal loans. In this paper, we contrast the two and their impact on children's schooling using longitudinal data from Nicaragua. To address endogeneity, we utilize both household fixed effects and locality–year fixed effects. Our results indicate that, on average, children from borrowing households fare worse than children from nonborrowing households, with male borrowers having a disproportionately negative effect on boys, and vice versa for girls and female borrowers. Informal credit is found to have a protective effect on school attendance, but the effects of formal and informal credit on cumulative schooling are found to be statistically equivalent. However, this appears to mask considerable heterogeneity within informal borrowing.     

Schooling choices: Preferences, discount rates, and rates of return

This paper develops an empirical model to identify the structural parameters of schooling preferences and human capital production. Our model distinguishes between consumption and investment motives with regard to schooling. The results show that both motives matter. Preferences for schooling vary with social background and ability. Children from poorer social backgrounds and of lower ability have a lower preference for schooling. The discount rate that enters the net value of lifetime income varies with social background as well. The marginal rate of return to schooling decreases with ability and schooling. On average the marginal rate of return is 7.3 per cent, which can be contrasted with a `Mincerian' rate of return equal to 4.8 per cent. This indicates that the usual OLS estimate underestimates the true rate of return. First version received: November 1997/Final version received: February 1999     

Life expectancy and human capital: long-run evidence from a panel of countries

This article examines the long-run impact of life expectancy on human capital investment for a panel of 14 countries over the period 1870–2010. Using recently developed panel time series techniques, we find (i) that life expectancy at birth has a statistically significant long-run effect on schooling and (ii) that long-run causality is unidirectional from life expectancy to schooling.     

Endogenous Farmer Schooling and the Application of High-Yielding Variety Technology in a Less-Developed Country

The paper uses data from the World Bank's Pakistan Integrated Household Survey to study the effect of farmer schooling on the application of high-yielding variety technology in Pakistan in 1990–91. Unlike previous studies of the role of schooling in agriculture in less-developed countries, it emulates estimation of Mincer earnings functions to treat schooling as an endogenous variable. This purges the estimates of inconsistency arising from positive correlation between unobserved farmer ability and schooling, and measurement errors in observed schooling. A measure of access to schools identifies the true causal effect of schooling on the use of improved seeds.     

Schooling and Citizenship in a Young Democracy: Evidence from Postwar Germany

This paper examines whether schooling has a causal impact on individuals' political behavior. Between 1949 and 1969, the number of compulsory years of schooling in the Federal Republic of Germany was gradually increased across all federal states. These legislative changes provide an opportunity to investigate the causal impact of schooling on political behavior. Years of schooling are found to be positively correlated with several political outcomes. However, there is little evidence of a causal effect. This study conjectures that there is ample historical evidence to support the hypothesis that the fundamentals of democracy were already learned earlier in school, potentially outweighing the political returns of schooling in Germany.     

The causal effects of parents’ schooling on children's schooling in urban China

Parental schooling is widely thought to improve child outcomes. But most studies on parental-child relations are associative, without control for estimation problems, such as unobserved intergenerationally-correlated endowments, if causality is of interest. The few exceptions are relatively recent studies that focus on high-income countries (HICs), with their much different contexts than the low- and middle-income countries (LMICs) in which the vast majority of children globally are growing up. This paper estimates the causal (conditional on the assumptions for the model) relationships between parents’ schooling and their children's schooling in the most populous LMIC, using adult identical (monozygotic, MZ) twins data from urban China. Our ordinary least-squares estimates show that one-year increases in maternal and paternal schooling are associated, respectively, with 0.4 and 0.5 more years of children's schooling. However, if we control for genetic and other endowment effects by using within-MZ fixed effects, the results indicate that mothers''and fathers’ schooling have no significant effects on children's schooling. Our main results remain with various robustness checks, including controlling for measurement error. These results suggest that the positive associations between children's and parents’ schooling in standard cross-sectional estimates in this major LMIC are mainly due to the correlation between parents’ unobserved endowments and their schooling and not the effects of their schooling per se.     

Gender‐specific Human Capital,Openness and Growth: Exploring the Linkages for South Asia

Using data covering 1970–2008 for South Asia, this study investigates the influence of human capital disaggregated by gender, on economic growth. We use an extended version of the Solow growth model with per capita gross domestic product (GDP) a function of the key variables, viz. physical capital accumulation, human capital accumulation, trade openness and capital flows, fiscal policy and financial development. The key contribution of this study is to show that openness when interacted with the human capital stock disaggregated by gender, has differential impacts on economic growth. While the positive impact of male secondary schooling captures the direct skill effect relative to primary schooling, the marginal influence of female primary/secondary schooling fails to show a positive impact on growth at higher levels of openness. An implication stemming from this study is that educational opportunities for females at the secondary level should be increased for South Asia.     

Individual heterogeneity in the returns to schooling: instrumental variables quantile regression using twins data

Considerable effort has been exercised in estimating mean returns to education while carefully considering biases arising from unmeasured ability and measurement error. Recent work has investigated whether there are variations from the “mean” return to education across the population with mixed results. We use an instrumental variables estimator for quantile regression on a sample of twins to estimate an entire family of returns to education at different quantiles of the conditional distribution of wages while addressing simultaneity and measurement error biases. We test whether there is individual heterogeneity in returns to education and find that: more able individuals obtain more schooling perhaps due to lower marginal costs and/or higher marginal benefits of schooling and that higher ability individuals (those further to the right in the conditional distribution of wages) have higher returns to schooling consistent with a non-trivial interaction between schooling and unobserved abilities in the generation of earnings. The estimated returns are never lower than 9 percent and can be as high as 13 percent at the top of the conditional distribution of wages but they vary significantly only along the lower to middle quantiles. Our findings may have meaningful implications for the design of educational policies.     

Social learning,neighborhood effects,and investment in human capital: Evidence from Green-Revolution India

This paper empirically identifies social learning and neighborhood effects in schooling investments in a new technology regime. Social learning implies that learning is most efficient when observed heterogeneity in schooling is greatest. The estimates of learning-investment rule, from farm household panel data at the onset of the Green Revolution in India, show that (i) agents learn about schooling returns from income realizations of their neighbors, and (ii) the speed of learning is high when the variation of schooling is large. Thus, schooling distribution of the parents' generation in a community has externalities to schooling investments in children. Simulations show that the variations in schooling within and across communities generate variations in child enrollment rate and average household income.     

International migration,remittances, and schooling: evidence from El Salvador

We examine the effect of remittances from abroad on households' schooling decisions using data for El Salvador. Following the massive war-related emigration of the 1980s, remittances became a significant source of household income throughout the 1990s. We use the Cox proportional hazard model to examine the determinants of school attendance. Measuring income from a source that is uncorrelated with parental schooling—remittances—, we find that remittances have a large, significant effect on school retention. We estimate that while household income net of remittances has a small, though significant, impact on the hazard of leaving school in rural and urban areas, remittances have a much larger impact on the hazard of leaving school. In urban areas, the effect of remittances is, at its smallest, 10 times the size of the effect of other income. In rural areas, the effect of remittances is about 2.6 times that of other income. Our finding is of interest in that it suggests that subsidizing school attendance, particularly in poor areas, may have a large impact on school attendance and retention, even if parents have low levels of schooling.     

Proxying Ability by Family Background in Returns to Schooling Estimations is Generally a Bad Idea*

When schooling is measured with error and data on ability are lacking, return to schooling estimates will be subject to positive omitted variable bias (OVB) and negative measurement error bias (MEB). We investigate how these biases are affected when ability is proxied by family background variables. We show that the effect on OVB is uncertain, while MEB invariably increases in magnitude. Our empirical analysis demonstrates that MEB generally dominates OVB. With more background variables or increased measurement error, the total bias rapidly becomes negative and increasing in magnitude, thereby driving the return estimate further and further away from the true value.     

Impact of individual characteristics and sociocultural environment on academic success

This article aims at ascertaining the factors of academic success and failure of 1,980 freshmen enrolled for the first time at the University of Brussels in 1987, by means of an ordered probit methodology. The results confirm the impact of variables characterizing social as well as cultural capital of the students. They highlight the significant impact of schooling record prior to attending a university and suggest the importance of variables such as sex and nationality. The results illustrate the respective roles of mothers in transmitting verbal skills and of siblings in conveying "inside information" on university life. Finally, they stress the essential role played by ability, which is proxied by a filtered measure of high school results.The authors would like to thank A. de Palma, F. Thys-Clément, and A. Micomibi for their comments, as well as R. Kurgan-Van Hetenryk.     

Indian residential schools: Height and body mass post‐1930

We study the effects of Canadian Indian residential schooling on two anthropometric measures of health during childhood: adult height and body weight. We use repeated cross‐sectional data from the 1991 and 2001 Aboriginal Peoples Survey and leverage detailed historical data on school closures and location to make causal inferences. We find evidence that, on average, residential schooling increases adult height and the likelihood of a healthy adult body weight for those who attended. These effects are concentrated after the 1950s, when the schools were subject to tighter health regulations and students were selected to attend residential school based partly on their need for medical care that was otherwise unavailable. Residential schooling is only one policy in Canada that had an impact on the health of status First Nations peoples, so our results must be understood in the broader social context. Taken in context, our results suggest that health interventions in later childhood can have significant impacts on adult health. We also document significant increases in height and body weight for status peoples born after the 1960s, suggesting substantial changes in diet and living conditions during this period.     

A note on schooling and wage inequality in the public and private sector

The few studies that have examined the wage impact of education across the earning distribution have focused on high-income countries and show education to be more profitable at the top of the distribution. The implication is that education may increase inequality. Extending the analysis to 16 East Asian and Latin American countries, in Latin America we observe a pattern similar to that of Europe/North America (increasing wage effects), while in East Asia the wage effects are predominantly decreasing by earnings quantile. However, once the analysis is performed separately for the public and the private sector, it is revealed that the strongly decreasing impact of schooling on earnings in the public sectors of East Asian countries is responsible for the overall observed decreasing pattern, while the impact of schooling on earnings in the private sectors of these countries is non-decreasing.     

Labor Income Taxation,Human Capital,and Growth: The Role of Childcare*

In this paper, we examine the effects of labor income taxation on growth in an overlapping generations model in which schooling and childcare play a role in the production of human capital. We compare such effects with those obtained in a model in which only schooling matters for skill formation. We show that the omission of childcare from the technology of skill formation can bias the results related to the impact of labor income taxation on growth.     

Lower and upper bounds of returns to schooling: An exercise in IV estimation with different instruments

Several recent studies based on `exogenous' sources of variation in educational outcomes show IV estimates of returns to schooling that are substantially higher than the corresponding OLS estimates. Card (1995a, Earnings, schooling, and ability revisited. Research in Labor Economics 14, 23–48) suggests that these results are explained by the existence of heterogenity in individual returns and by the fact that these studies are based on instruments that influence only the educational decision of individuals with high marginal returns due to either liquidity constraints or to high ability. This conclusion is consistent with the local average treatment effect (LATE) interpretation of IV (Imbens and Angrist (1994, Identification and estimation of local average treatment effects. Econometrica 62, 467–475) according to which IV identifies only the average returns of those who comply with the assignment-to-treatment mechanism implied by the instrument. We show evidence for Germany suggesting that returns to schooling are heterogeneous, instruments matter and the LATE interpretation of IV makes sense. With an appropriate choice of instruments we also show how IV can be used to approximate the range of variations of returns to schooling in Germany.
