This paper's findings suggest that an arbitrary Chinese policy that greatly increases total suspended particulates (TSPs) air pollution is causing the 500 million residents of Northern China to lose ...more than 2.5 billion life years of life expectancy. The quasi-experimental empirical approach is based on China’s Huai River policy, which provided free winter heating via the provision of coal for boilers in cities north of the Huai River but denied heat to the south. Using a regression discontinuity design based on distance from the Huai River, we find that ambient concentrations of TSPs are about 184 μg/m ³ 95% confidence interval (CI): 61, 307 or 55% higher in the north. Further, the results indicate that life expectancies are about 5.5 y (95% CI: 0.8, 10.2) lower in the north owing to an increased incidence of cardiorespiratory mortality. More generally, the analysis suggests that long-term exposure to an additional 100 μg/m ³ of TSPs is associated with a reduction in life expectancy at birth of about 3.0 y (95% CI: 0.4, 5.6).
This paper finds that a 10-μg/m³ increase in airborne particulate matter particulate matter smaller than 10 μm (PM10) reduces life expectancy by 0.64 years (95% confidence interval = 0.21–1.07). This ...estimate is derived from quasiexperimental variation in PM10 generated by China’s Huai River Policy, which provides free or heavily subsidized coal for indoor heating during the winter to cities north of the Huai River but not to those to the south. The findings are derived from a regression discontinuity design based on distance from the Huai River, and they are robust to using parametric and nonparametric estimation methods, different kernel types and bandwidth sizes, and adjustment for a rich set of demographic and behavioral covariates. Furthermore, the shorter lifespans are almost entirely caused by elevated rates of cardiorespiratory mortality, suggesting that PM10 is the causal factor. The estimates imply that bringing all of China into compliance with its Class I standards for PM10 would save 3.7 billion life-years.
We link industry-level data on trade and offshoring with individual-level worker data from the Current Population Surveys from 1984 to 2002. We find that occupational exposure to globalization is ...associated with significant wage effects, while industry exposure has no significant impact. We present evidence that globalization has put downward pressure on worker wages through the reallocation of workers away from higher-wage manufacturing jobs into other sectors and other occupations. Using a panel of workers, we find that occupation switching due to trade led to real wage losses of 12 to 17 percentage points.
Many scholars argue that the persistence of son preference in China is driven by greater anticipated old-age support from sons than from daughters and the absence of formal financial mechanisms for ...families to save for retirement. The introduction of a voluntary old-age pension program in rural China in the 1990s presents the opportunity to examine (1) whether parents with sons are less likely to participate in pension plans and (2) whether providing access to pension plans affects parental sex-selection decisions. Consistent with the first hypothesis, we find that parents with sons are less likely to participate in the pension program and have less financial savings for retirement. Consistent with the second hypothesis, we find that an increase in county-level pension program availability is associated with a slower increase in the sex ratio at birth.
China's rapid industrialization has led to a severe deterioration in water quality in the country's lakes and rivers. By exploiting variation in pollution across China's river basins, I estimate that ...a deterioration of water quality by a single grade (on a six-grade scale) increases the digestive cancer death rate by 9.7%. The analysis rules out other potential explanations such as smoking rates, dietary patterns, and air pollution. I estimate that doubling China's levy rates for wastewater dumping would save roughly 17,000 lives per year but require an additional $500 million in annual spending on wastewater treatment.
High ratios of males to females in China have concerned researchers (Sen 1990, Yi et al. 1993) and the recent increase has alarmed policymakers worldwide. This paper presents an analysis of China's ...census data that indicates that the "missing girls" phenomenon is causally linked to enforcement of the One Child Policy. Fertility is lower and sex ratios are higher among those under stricter fertility control, and the overall increase in the sex ratio is driven by an increase in the prevalence of sex selection among first and second births. By exploiting regional and temporal variation in fines levied for unauthorized births, I find that higher fine regimes discourage fertility, but are associated with higher ratios of males to females.
In the wake of the one-child policy of 1979, China experienced an unprecedented rise in the sex ratio at birth (ratio of male to female births). In cohorts born between 1980 and 2000, there were 22 ...million more men than women. Some 10.4 percent of these additional men will fail to marry, based on simulations presented here that assess how different scenarios for the sex ratio at birth affect the probability of failure to marry in 21st century China. Three consequences of the high sex ratio and large numbers of unmarried men are discussed: the prevalence of prostitution and sexually transmitted infections, the economic and physical well-being of men who fail to marry, and China's ability to care for its elderly, with a particular focus on elderly males who fail to marry. Several policy options are suggested that could mitigate the negative consequences of the demographic squeeze.
This paper examines the impact of multinational firm entry into local labor markets on employment, productivity, and wages. It exploits the People’s Republic of China’s rapid implementation of ...economic reforms and assignment of cities to special economic zone status in the 1980s and 1990s. Using data on both firms and workers, it is found that these policies increased foreign direct investment, which raised average labor productivity in these labor markets. However, only modest increases in real median wage rates across these cities are observed in the face of large increases in wage inequality and rising local prices, limiting the benefits to most workers in these cities. Evidence is presented that corporate profits captured most of the increase in productivity in these areas.
This paper provides an examination of China’s residential real estate market at the county level using data from that country’s 2000 census. The market is a new one, having only been fully ...established in 1998. The analysis in the paper is in the form of an aggregate (county-level) hedonic model specified in two versions. Global parameters results are estimated using spatial error model specifications while more local effects are estimated by geographically weighted regression. Global results are typical in that structural characteristics such as floor space and contextual characteristics such as level of in-migration are important in residential prices. Local results, however, indicate significant spatial variation in the effect of both structural amenities and locational context on housing prices. In a simpler specification, rents are shown to respond positively to both median house prices levels and the supply of apartments available at market prices, but also with significant spatial variation across China.
