    مستخلص: There is a large literature on the role infrastructure plays in economic development, but few papers document the causal effect of infrastructure on the sustainability of natural resources. We examine the effect of the arrival of two new national highways on ground water levels in a small agricultural county in the North China Plain - a region that produces most of the nation’s food grains. We first develop a conceptual framework to show that farmers located closer to the highways devote more acreage to crops that are water intensive. We then use a unique GIS-referenced dataset of all the 12,160 tube wells in this county to show that highway construction accelerates the drilling of new wells in farms closer to the highway. In addition, there is greater depletion of the groundwater in wells near the two highways relative to wells located farther away. Our estimated depletion rates near the two roads are at least 5 times higher relative to mean depletion rates in the North China Plain. We show suggestive evidence that depletion is caused by a switch from subsistence to commercial cropping, and intensification of farming practices adjacent to the highway. These results suggest that the environmental cost of new infrastructure building may be significant and needs to be incorporated in benefit-cost analysis

    مستخلص: We use county-level panel data to estimate the long-run effect of fine particulate matter (PM2.5) pollution on mortality in China. Causal inference relies on changes in local pollution correlated with demand shocks from export destinations amid the global economic crisis during the late 2000s. We find an economically and statistically significant impact of the long-term exposure to PM2.5 on cardiovascular and respiratory mortality. Mortality impacts are largest for those 65 years and older. Using the variability in pollution levels both across time and space, our analysis provides evidence of a concave dose-response, with diminishing marginal mortality impacts of pollution at levels beyond those in developed nations

    مستخلص: Rising energy expenditures due to more intensive use of energy in modern agriculture and increasing energy prices may affect rural households' agricultural incomes, particularly the incomes of the rural poor in developing countries. However, the exact link between energy costs and income among the rural poor needs further empirical investigation. This paper aims to gain a deeper understanding of the relationship between energy use and family income, using household-level panel data collected from 500 potato farmers in a poor region of Northern China, where eliminating poverty by 2020 is now the top government priority. The findings indicate that potato plays an important role in the surveyed families' incomes, and the energy costs of potato production have a significant negative relationship with family income. However, the significance of the negative relationship is robust only for farmers with low economic standing, such as those living below the poverty line or just above it. Energy costs also have a significant negative relationship with the family incomes of those cultivating a certain size of potato-sown area, but this relationship becomes insignificant when farmers have too small of a potato-sown area. These findings indicate that in general, reducing energy costs helps the poor increase their income but is not necessarily helpful to those with high economic standing or a relatively small potato-sown area. If rural development policies are to support poverty reduction and energy savings (at least in major potato production regions), interventions aimed at energy cost reduction may be effective only for the poor whose family income depends, to a relatively high degree, on potato production
