Using data from China's Urban Household Survey and exploiting China's mandatory retirement policy, we use the regression discontinuity approach to estimate the impact of retirement on household expenditures. Retirement reduces total non-durable expenditures by 19%. Among the categories of non-durable expenditures, retirement reduces work-related expenditures and expenditures on food consumed at home but has an insignificant effect on expenditures on entertainment. After excluding these three components, retirement does not have an effect on the remaining non-durable expenditures. It suggests that the retirement consumption puzzle might not be a puzzle if an extended life-cycle model with home production is considered.

We find that the increased supply of college graduates resulting from college enrollment expansion in China increases college premiums for older cohorts and decreases college premiums for younger cohorts. This finding is inconsistent with the canonical model that assumes substitution among workers of different ages. We subsequently build a simple model that considers complementarities among workers of different ages and different skill levels. Our model predicts that the college premium of senior workers increases with the supply of young college graduates when skill is a scarce resource. The model's predictions are supported by empirical tests.

In this paper, we consider the sources and prospects for economic growth in China with a focus on human capital. First, we provide an overview of the role that labor has played in China's economic success. We then describe China's hukou policy, which divides China's labor force into two distinct segments, one composed of rural workers and the other of urban workers. For the rural labor force, we focus on the challenges of raising human capital by both increasing basic educational attainment rates as well as the quality of education. For the urban labor force, we focus on the issues of further expanding enrollment in college education as well as improving the quality of college education. We use a regression model to show the typical relationship between human capital and output in economies around the world and demonstrate how that relationship has evolved since 1980. We show that China has made substantial strides both in the education level of its population and in the way that education is being rewarded in its labor markets. However, as we look ahead, our results imply that China may find it impossible to maintain what appears to be its desired growth rate of 7 percent in the next 20 years; a growth rate of 3 percent over the next two decades seems more plausible. Finally, we present policy recommendations, which are rooted in the belief that China continues to have substantial room to improve the human capital of its labor force.

This study examines the effects of fertility on household structure and parental labor supply in China. To solve the endogeneity problem, we use a unique survey on households with twin children and a comparison group of non-twin households. The ordinary least squares estimates show a negative correlation between fertility and parental labor supply in rural China. Using twinning as a natural experiment, we do not find evidence on the negative effects of fertility on parental labor supply. By contrast, we find that the twinning-induced increase in fertility significantly enhances the coresidence of grandparents in rural China. We suggest that the negative effects of fertility on parental labor supply are mitigated by the childcare provided by grandparents in rural China. We also find that fertility does not induce coresidence of grandparents in urban China. Our results have important implications for population and public childcare policies.

China’s land reform in 1978–84 unleashed rapid growth in farm output and household income. In new data on reform timing in 914 counties, we find an immediate trend break in the fraction of male children following the reform. Among second births that followed a firstborn girl, sex ratios increased from 1.1 to 1.3 boys per girl in the 4 years following reform. Larger increases are found among families with more education. The land reform estimate is robust to controlling for the county-level rollout of the One Child Policy. Overall, we estimate land reform accounted for about 1 million missing girls.

China is the world's largest user of industrial robots. In 2016, sales of industrial robots in China reached 87,000 units, accounting for around 30 percent of the global market. To put this number in perspective, robot sales in all of Europe and the Americas in 2016 reached 97,300 units (according to data from the International Federation of Robotics). Between 2005 and 2016, the operational stock of industrial robots in China increased at an annual average rate of 38 percent. In this paper, we describe the adoption of robots by China's manufacturers using both aggregate industry-level and firm-level data, and we provide possible explanations from both the supply and demand sides for why robot use has risen so quickly in China. A key contribution of this paper is that we have collected some of the world's first data on firms' robot adoption behaviors with our China Employer-Employee Survey (CEES), which contains the first firm-level data that is representative of the entire Chinese manufacturing sector.

Using a recently constructed dataset that draws on the China Employer–Employee Survey, this paper provides new evidence on the earnings gap between rural migrant and urban manufacturing workers in the People's Republic of China. When we only control for province fixed effects, we find that rural migrant workers are paid 22.3% less per month and 32.2% less per hour than urban workers. We find that the gap in hourly earnings is larger than the gap in monthly earnings because rural migrant workers tend to work an average of 5.6% more hours per month than urban workers. Using these data, we also find that 87.4% of the monthly earnings gap and 73.9% of the hourly earnings gap can be attributed to differences in the individual characteristics and human capital levels of rural migrant and urban workers. Furthermore, we find that this unexplained earnings gap varies among different groups of workers. The earnings gap is much larger (i) for workers in state-owned enterprises than in nonstate-owned enterprises, (ii) for college-educated workers than workers with lower levels of educational attainment, and (iii) in Guangdong province than in Hubei province.

Drawing on data from a random sample of manufacturing firms collected in 2016 for the China Employer-Employee Survey (CEES), we examine differences in measures of productivity and financial returns between state-owned enterprises (SOEs) and private firms in China. The summary statistics show that labor productivity and total factor productivity are generally higher at SOEs than at private firms, but the productivity advantage of SOEs can mostly be explained by the higher levels of human capital of their workers, greater market power, and better management. Furthermore, SOEs’ advantage in productivity exists only in industries with higher SOE concentrations. In contrast, measures of financial returns—return on assets and return on equity—are lower for SOEs than for private firms. We believe that these results may reflect the fact that SOEs generally have easier access to capital, human capital, and markets than other types of firms in China.

Policymakers in developing countries have prioritized the mass expansion of vocational education and training (VET). Evidence suggests, however, that the quality of VET can be poor. One possible reason given by policymakers for this is a lack of resources per student. The goal of this study is to examine whether the quality of VET in developing countries increases by investing greater resources per student. To achieve this goal, we examine the impacts of attending model schools (which have far more resources per student) compared with non-model schools (which have fewer resources) on a range of student cognitive, non-cognitive, and behavioral outcomes. Using representative data from a survey of approximately 12,000 VET students from China, multivariate regression and propensity score matching analyses show that there are no significant benefits, in terms of student outcomes, from attending model vocational high schools, despite their substantially greater resources.
