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.     

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.     

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.     

Child labor and schooling responses to anticipated income in South Africa

Forward looking, unconstrained households make child labor and schooling decisions considering their permanent income and weighing the relative returns to child time in various potential activities. The timing of anticipated changes in income should have no effect on child labor and schooling in a setting where households can borrow against permanent income. However, this study documents large increases in schooling attendance and declines in total hours worked when black South African families become eligible for fully anticipatable social pension income. As an explanation, the data are most consistent with liquidity constraints for black elder males forcing rural families into less schooling for boys than they would choose absent the constraint, perhaps because of schooling costs.     

Estimating returns to education in urban China: Evidence from a natural experiment in schooling reform

Whereas there is a large literature on estimating returns to education in China, few studies have attempted to address the endogeneity of schooling choices. We explore the arguably exogenous changes in the duration of secondary education as the instrumental variable to identify the causal effect of years of schooling in urban China. The schooling years in most middle schools were reduced from three years to two years during the Cultural Revolution. The Chinese government gradually restored the middle school education years from two years to three years after 1978. An important feature of these policy changes is their large geographic variations. From local gazetteers, we find out the exact years when education years were reduced from three to two and when they were restored from two to three. Using the exogenous variation in schooling reform, we estimate that the returns to education are 12.7% for both monthly wage and disposable income.     

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 gender difference in wages and the returns to schooling over the great recession in the U.S.

This paper examines the effects of the Great Recession on the gender difference in hourly wage and the rate of return to schooling in the United States. Using data from American Community Survey 2000–2015, we find that the male-female difference in hourly wage declined during and after the recession. The Great Recession decreased earnings for both men and women, especially for those with more education. We also find there is a significant gender difference in the effects of the Great Recession on the returns to schooling. The Great Recession increased the rate of return to schooling for both men and women, and the female-male difference in the returns to schooling decreased by 0.4 percentage points in the post-recession period. The change of the gender difference in the returns to schooling can be explained by the wage structure change for men and women over the recession.     

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.     

ARE COGNITIVE SKILLS RELEVANT IN GENDER EARNINGS DECOMPOSITIONS?

While cognitive skills are known to play an important role in labour market success, empirical evidence is mainly concentrated in its effect on returns to schooling. Evidence on the role of cognitive skills in gender earnings gap decompositions is virtually absent. I use two approaches to investigate the potential for cognitive skills to affect the size and pattern of the unexplained component of the earnings gap (‘relative discrimination’) across the wage distribution, using data from the International Adult Literacy Survey (IALS). It has been shown that when the raw cognitive score is used to control for cognitive skills, the return to schooling cognitive skills is generally underestimated. Once a distinction is made about the origins of cognitive skills (acquired in school versus outside the school), the returns to cognitive skills can vary depending on their origin. I find that using the raw score to control for cognitive skills does not result in any significantly different estimates of the unexplained component of the gap compared to when cognitive skills are not controlled for. However, once cognitive skills by origin of skill are used in place of total cognitive skills, the results change substantially for three of the five countries examined.     

Heterogeneity in the economic returns to schooling among Chinese rural–urban migrants, 2002–07

This paper analyses the returns to schooling among Chinese rural migrants using data from the 2002 and 2007 China Household Income Project. Our non‐parametric estimates show substantial heterogeneity in the schooling rates of return among migrant workers. While the returns to schooling for the overall sample have increased over time, this result is driven by the substantial increases in the schooling coefficients of female migrants. We expect the endogeneity biases in the estimated schooling returns to be decreasing after considering the change in the ability distribution of migrant workers during 2002–07.     

“文化大革命”在日本（1966～1972）——中国革命对日本的冲击和影响

从“文革”发端的1965年到日中恢复邦交的1972年，“文化大革命”的浪潮席卷日本。本文以当时日本综合性杂志的有关中国报道为素材，从日本论坛的“中国论”的变迁过程来探讨“文革”对日本的影响和）中击，同时也回顾了“文革”之火在日本，从学生运动到工人阶级，从“全共斗”到新左翼各派，从学园纷争到个别斗争的阵地战的变迁过程。本文认为，研究“文革”对日本的冲击与影响，不能仅仅将其作为一个时期研究中国的成果总结来认识，还要将其置于战后日本精神史的高度进行深入认识。     

Adaptability, productivity, and educational incentives in a matching model

We study the connections between the labour market and the education sector in a matching framework with ex-post wage bargaining. Workers have multidimensional skills and the search market is segmented by technology. Education is a time-consuming activity and determines jointly the scope - or adaptability - and intensity - or productivity - of individual skills. We establish three main results. First, unemployment provides incentives to schooling by raising the need for adaptability. Second, private returns to productivity are below social returns, but no hold-up phenomenon is involved. Third, due to wage and congestion externalities, private returns to adaptability exceed social returns. As a consequence, both over- and under-education may take place in equilibrium.     

The human capital consequences of civil war: Evidence from Guatemala

We combine data from the 2002 National Population Census and the distribution of the number of human rights violations and victims across 22 departments to examine how Guatemala's 36-year-long civil war affected human capital accumulation. The year of birth and the department of birth jointly determine an individual's exposure during school age to three different periods of the civil war, namely the initial period (1960-1978), the worst period (1979-1984), and the final period (1985-1996). We find a strong negative impact of the civil war on the education of the two most disadvantaged groups, namely rural Mayan males and females. Among rural Mayan males, those who were school age during the three periods of the civil war in departments where more human rights violations were committed completed 0.27, 0.71, and 1.09 years less of schooling respectively whereas rural Mayan females exposed to the three periods of the war completed 0.12, 0.47, and 1.17 years less of schooling respectively. Given an average of 4.66 and 3.83 years of schooling for males and females, these represent declines of 6, 15, and 23% for males and 3, 12, and 30% for females. Our results are robust to the inclusion of indicators for department of residence, year of birth, and controls for different trends in education and human development in war-affected and peaceful departments of Guatemala and suggest that the country's civil war may have deepened gender, regional, sectoral, and ethnic disparities in schooling.     

Is wealth found in the soil or in the brain? Investing in farm people in Malawi

Should a typical developing country invest more in agriculture or education? At what stage of development is it optimal to invest more in each of these sectors? These are important questions that governments of developing countries grapple with when designing investment plans. In this paper, I propose a soil–human capital conceptual framework of development and use it to explain estimates of agricultural returns to schooling in Malawi. I use panel survey data for Malawi and rely on the exogenous education policy changes and spatial variation in access to schooling to identify effects of schooling on agricultural incomes. In addition, I correct for selection into income activities within a panel data and instrumental variables estimation framework. I find annual agricultural returns to schooling in Malawi of 3%–4% after correcting for selection and unobserved heterogeneity and 7% in the uncorrected specifications. I also find consistently higher returns to schooling in the nonagricultural sector for those not living in the village of birth and higher returns in the agricultural sector for those living in the village of birth. Given the size of the farm sector, wealth in Malawi is still in the soil, but that future growth in wealth depends on human capital investments.     

城镇居民教育收益率的地区差异及其解释

利用中国社会科学院经济研究所"中国城乡居民收入分配"课题组1995年和2002年的家庭抽样调查数据,本文使用分层线性模型重新估计了1995年、2002年我国居民的教育收益率,得到了不同于OLS估计的结果:(1)我国城镇居民教育收益率的地区差异很大,差异主要来源于省内各城市之间,来源于省间的差别并不显著;(2)计算了省内城市劳动力市场化程度对当地教育收益率的边际影响,发现劳动力市场的发育确实有利于提高教育收益率,而且劳动力市场化程度的差异在一定程度上为各地教育收益率的差异提供了解释。     

Have the returns to education really increased in Vietnam? Wage versus employment effect

Many studies have analyzed changes in the returns to education in globalizing economies using the Mincerian framework. These studies have typically estimated the returns to education in terms of changes in wages rather than employment, effectively ignoring the fact that during globalization not only wages but also employment patterns are affected. In this paper we use four large-scale representative household surveys from the transition economy Vietnam for the period 1998–2006 to estimate the returns to education taking into account both changes in wages and employment. The results show that the estimated increases in returns to education are lower once changes in employment patterns are taken into account.     

Optimal Schooling Investments and Earnings: An Analysis Using Australian Twins Data

The potential impact that unobserved ability can have on both schooling and earnings outcomes has been modelled by Ashenfelter and Rouse (1998). This paper applies their model to the Australian Twins Sample. The best estimate of the return to schooling for genetically identical (or MZ) twins is 8.9 per cent. Measurement errors in the schooling data are shown to constitute a more serious problem than the omission of the family effects that impact on ability. Individuals from higher ability families receive a lower marginal benefit from their investment in human capital.     

Managerial ability and capital flows

Capital flows with low intensity and flows to middle-income countries. Physical and human capital alone cannot explain this pattern. I present a model to show how managerial ability—the ability to run risky projects—can increase total factor productivity and explain the pattern of capital flows. The model implies that countries with more high-ability managers use more risky projects and have higher productivity. I define proxies for managerial ability with data on physical and human capital, schooling, and entrepreneurship. Consistent with the pattern of capital flows, the model predicts similar returns to capital across countries and higher returns in middle-income countries.

The impact of rustication on sent-down cohorts�� income

We estimate the impact of rustication on sent-down cohorts during the decade period of the Cultural Revolution, relying on econometric methods and policy reviewing. The data used from the Chinese Household Income Project (CHIP) for the years 1995 and 2002 show that the average income of sent-down cohorts is higher than those who were not sent-down, which seems to conflict with the human capital theory that predicts that education increases future expected returns. This paper separates the impact of ability, family background, and policies on intellectual youth and finds that their rustication had a significant negative effect for the sent-down cohorts. Correction for sent-down cohorts’ working experience from the year they went to the countryside decreases the income inequality among low-income sent-down cohorts, and compensates for the negative effects of the sent-down experience.
