Search equilibrium and social and private returns to education

Social and private returns to education are computed using the structural estimates of an extended Burdett-Mortensen search equilibrium model. The extension includes different skill groups linked via a production function with variable degree of homogeneity, allowing thereby for a unimodal earnings density with a decreasing right tail. We find that the decreasing unemployment risk for higher skill groups and the absence of tuition fees in Germany increase private returns and lead to a too large share of high skilled individuals in the workforce, which is suboptimal from the social point of view.     

A microfoundation for increasing returns in human capital accumulation and the under-participation trap

This paper considers educational investment, wages and hours of market work in an imperfectly competitive labour market with heterogeneous workers and home production. It investigates the degree to which there might be both underemployment in the labour market and underinvestment in education. A central insight is that the ex post participation decision of workers endogeneously generates increasing marginal returns to education. Although equilibrium implies underinvestment in education, optimal policy is not to subsidise education. Instead it is to subsidise labour market participation which we argue might be efficiently targeted as state-provided childcare support.     

Economic transition, higher education and worker productivity in China

We investigate the role of education on worker productivity and firms' total factor productivity using a panel of firm-level data from China. We estimate the returns to education by calculating the marginal productivity of workers of different education levels based on estimates of the firm-level production function. We also estimate how the education level of workers and CEO contributes to firms' total factor productivity. Estimated marginal products are much higher than wages, and the gap is larger for highly educated workers. Our estimate shows that an additional year of schooling raises marginal product by 30.1%, and that CEO's education increases TFP for foreign-invested firms. Estimates vary substantially across ownership classes, the effect of schooling on productivity being highest in foreign-invested firms. We infer that market mechanisms contribute to a more efficient use of human capital within firms.     

The Cultural Revolution and returns to schooling in China: Estimates based on twins

This paper investigates the returns to schooling in China for the Cultural Revolution (CR) cohort and the non-CR cohort using a new set of Chinese twins data. Applying the fixed-effects model on twins data, which helps to control for the genetic and family background effects, this paper examines whether the CR cohort has smaller economic returns to schooling than the non-CR cohort. The empirical results in this paper indicate that the Cultural Revolution has not played a significantly adverse role in the returns to schooling.     

Estimating returns to education using twins in urban China

This paper empirically estimates the return to education using twins data that the authors collected from urban China. Our ordinary least-squares estimate shows that one year of schooling increases an individual's earnings by 8.4%. If we use a within-twin fixed effects model, the return is reduced to 2.7%, but rises to 3.8% after the correction of measurement error. These results suggest that a large portion of the estimated returns to education is due to omitted ability or the family effect. We further investigate why the true return is low and the omitted ability bias high, and find evidence showing that it may be a consequence of China's education system, which is highly selective and exam oriented. More specifically, we find that high school education may mainly serve as a mechanism to select college students, but as a human capital investment per se it has low returns in terms of earnings. In contrast, both vocational school education and college education have a large return that is comparable to that found in the United States.     

Long-run costs of piecemeal reform: Wage inequality and returns to education in Vietnam

In this paper, we examine changes in wage structure and wage premia during Vietnam’s transition from command to market economy. Relative to other work in this literature, our paper is unique in that we identify the policies that lead to such changes. By examining skill premium trends along the two dimensions of particular importance to the transition—state or non-state firms, and traded or non-traded industries—we are able to separate the contribution of external liberalization to wage growth and rising skill premia from that of domestic labor market reforms, and to examine potential interactions between the two types of reform. The results point to the high cost of incomplete reform in Vietnam. Capital market segmentation creates a two-track market for skills, in which state sector workers earn high salaries while non-state workers face lower demand and lower compensation. Growth is reduced directly by diminished allocative efficiency and reduced incentives to acquire education, and indirectly by higher wage inequality and rents for workers with access to state jobs.     

Occupations and the evolution of gender differences in intergenerational socioeconomic mobility

This paper analyzes intergenerational mobility experiences of daughters and sons with respect to their fathers’ occupational status and documents changes in gender differences over time. While women have been in occupations with lower overall earnings potential, men are more likely to be in occupations characterized by long hours and low returns. The mobility gap in earnings has been closing and a mobility advantage with respect to education has been emerging.     

Tenure, business cycle and the wage-setting process

We analyze the interaction between job tenure and external labor market conditions in wage determination. First, we introduce a model that combines job matching with business-cycle effects. As the employment relationship progresses, the worker appropriates a portion of the value of the match-specific human capital she accumulates, gradually becoming shielded from the cyclical variations in external labor market conditions: the employment relationship is progressively “internalized”. Then, we present empirical evidence supporting this prediction: the elasticity of wages to the unemployment rate decreases with tenure. This finding is robust to different specifications that allow for job heterogeneity, and it contributes to the interpretation of recent evidence of changes in the effect of the business cycle on wages.     

Human capital values and returns: Bounds implied by earnings and asset returns data

We provide theory for calculating bounds on both the value of an individual?s human capital and the return on an individual?s human capital, given knowledge of the process governing earnings and financial asset returns. We calculate bounds using U.S. data on male earnings and financial asset returns. The large idiosyncratic component of earnings risk implies that bounds on values and returns are quite loose. However, when aggregate shocks are the only source of earnings risk, both bounds are tight.     

Returns to education in professional football

After three years in college, football players face a trade-off between spending more time in college and pursuing a career in the National Football League (NFL). We analyze the salaries for rookies in the NFL and instrument the endogenous decision to enter the professional market with the month of birth (relative age effect). A player enjoys a 6 percent higher starting salary in the NFL for each additional year with the college team. The returns to education in professional sports are sizable and similar to returns to formal education.     

Mismatches in the Spanish Labor Market: Education vs. Competence Match

The accuracy of the match between a workers talents, skills, and capabilities and those required by his or her job has seldom been addressed in the empirical literature. However, a number of analyses on the match between workers education levels and those required by jobs have been published over the last 10 years. Obviously, the level of formal education completed by workers is more easily observed than their levels of human capital competences. Indeed, the latter would be rather difficult to observe. Nonetheless, this approximation is not straightforward, since formal education is only a mean for the acquisition of some human capital competences. We cross-examine the education match and the competence match between the supply and the demand of labor in Spain with data from 1998. Our results suggest that both types of matches do differ in their incidence, determinants, and wage consequences.     

Wage bargaining and turnover costs with heterogenous labor and perfect history screening

We study effects of mobility costs in a model of (Nash) wage bargaining between workers and firms, with instantaneous matching, heterogeneous workers, identical firms and free firm entry, and where firms can screen workers perfectly according to their previous work history but not their actual productivity. We derive the employment level and the minimum worker quality standard, in the market solution, and in the efficient solution established by a social planner. When workers have positive bargaining power, there is always some inefficient unemployment among desired workers in the market solution. The lowest hiring standard chosen by firms is higher than the planner's standard when firing costs are high relative to hiring costs, but may be lower in the opposite case. We show that any higher established hiring standard corresponds to a market equilibrium. The model explains a tendency for a high initial unemployment rate to remain high, particularly for low-skilled workers.     

Why Some Firms Train Apprentices and Many Others Do Not

Abstract. The latest study investigating the cost–benefit ratio of apprenticeship training for Swiss companies has shown that most apprentices offset the cost of their training during their apprenticeship on the basis of the productive contribution of the work they perform. Given this outcome, it is worth investigating why so many firms choose not to train apprentices. Maximum-likelihood selection models were used to estimate the net cost of training for firms without an apprenticeship programme. The models show, firstly, that non-training firms would incur significantly higher net cost during the apprenticeship period if they would switch to a training policy and, secondly, that this less favourable cost–benefit ratio is determined less by cost than by absence of benefit. For the apprenticeship system as such the results indicate that, as long as training regulations and the market situation permit a cost-effective training of apprentices, companies do not need specific labour market regulations or institutions to offer training posts. In this respect, the Swiss findings might be of interest for the ongoing German discussion about the expected repercussions of a more general labour market deregulation on the apprenticeship training system.     

The welfare costs of union wage compression

This paper calculates the quantitative significance of the welfare costs of union wage compression. This is done in a dynamic general equilibrium model with overlapping generations where agents choose both schooling (human capital) and assets (physical capital). The labor market in this model is characterized as a right-to-manage contract, which allows unions to compress wage differentials between high- and low-skilled workers, by implementing a binding minimum wage. This paper shows that when labor markets are competitive even low levels of wage compression lead to large welfare losses, since wage compression creates costly unemployment among low-skilled workers. The effect of wage compression on the supply of skilled labor, however, is rather small, since the disincentive effect of a lower, high-skilled wage is, to a large extent, offset by a lower opportunity cost of schooling due to higher unemployment.     

Technology and outsourcing: An explanation to the rising wage gap

The recent phenomenon of widening skilled–unskilled wage gap in both North and South has been either explained by a technological change or by increasing trade or globalization. The paper provides a new explanation and emphasizes that it is neither technology nor trade alone but both that have contributed to the widening wage inequality. It argues, using a two-country occupational choice model, that any technological improvement in North results in a rise in the skilled–unskilled wage gap in North via an increase in the productivity of skilled labor followed by a rise in the same in South via trade or the outsourcing activities of the northern firms. The extent of outsourcing or the number of northern firms that outsource jobs to South is endogenously determined in the model. The paper also analyzes some major economic impacts of such a technological upgradation in North on the southern economy.     

Parameter estimates comparison of earnings functions in the PSID and CPS data, 1976–2007

Comparing earnings equations in the Panel Study of Income Dynamics (PSID) and the Current Population Survey, we find that the PSID considerably underestimates the returns to education during the 1992–2007 period. Non-random selection in the PSID sample appears to be the reason.     

College Quality and Wages in the United States

Abstract. We estimate the effects of the quality of the college a student attends on their later earnings using data from a cohort of US college students from the late 1970s and early 1980s. We rely on a linear selection on observables identification strategy, which is justified in our context by a very rich set of conditioning variables. We find economically important earnings effects of college quality for men and women, as well as effects on educational attainment, spousal earnings and other demographic variables. These effects remain roughly constant over time and result primarily from effects on wages, rather than from effects on hours or labor force participation. We find that, over the lower part of the range of college quality, increases in college quality (which entail higher expenditures per student) pass a simple social cost–benefit test.     

OCCUPATIONAL AND INDUSTRY SPECIFICITY OF HUMAN CAPITAL IN THE BRITISH LABOUR MARKET

This paper builds on the recent literature on the importance of occupational and industry experience on wages and extends Kambourov and Manovskii's (2002) study using British data. Occupational experience is estimated to make a significant contribution to wage growth, while the evidence on industry specificity is not very supportive. The second contribution of the paper is that it assesses whether there is heterogeneity in the estimated returns to work experience across one-digit industries and occupations. The findings suggest that industry and occupational experience is important for individuals in professional and managerial jobs or jobs in the banking and finance sector.     

Effects of Health on Wages of Australian Men

This study uses the Household, Income and Labour Dynamics in Australia (HILDA) survey to investigate the effect of health on wages of working-age Australian men. A simultaneous equation model of health and wages is estimated to account for the endogeneity of health. The results confirm the findings in the literature that health has a significant and positive effect on wages; it is also found that treating health as exogenous underestimates the effect substantially. Although the reverse effect of wages on health is found to be insignificant, there is evidence on the endogeneity of health arising from unobserved factors.
