Xiaoqi Guo and James K Hammitt. 2009. “Compensating wage differentials with unemployment: Evidence from China.” Environmental and Resource Economics, 42, 2, Pp. 187-209. Publisher's VersionAbstract
We estimate the economic value of mortality risk in China using the compensating-wage-differential method. We find a positive and statistically significant correlation between wages and occupational fatality risk. The estimated effect is largest for unskilled workers. Unemployment reduces compensation for risk, which suggests that some of the assumptions under which compensating wage differentials can be interpreted as measures of workers’ preferences for risk and income are invalid when unemployment is high. Workers may be unwilling to quit high-risk jobs when alternative employment is difficult to obtain, violating the assumption of perfect mobility, or some workers (e.g., new migrants) may be poorly informed about between-job differences in risk, violating the assumption of perfect information. These factors suggest our estimates of the value per statistical life (VSL) in China, which range from approximately US$30,000 to US$100,000, may be biased downward. Alternative estimates adjust for heterogeneity of risk within industry by assuming that risk is concentrated among low-skill workers. These estimates, which are likely to be biased downward, range from US$7,000 to US$20,000.

This study developed a new approach to the valuation of health risk in China, for monetizing health damages of environmental degradation.

Jing Cao, Mun S Ho, and Dale W Jorgenson. 2009. “The local and global benefits of green tax policies in China.” Review of Environmental Economics and Policy, 3, 2, Pp. 231-250. Publisher's VersionAbstract
This article describes a multidisciplinary study of market-based policies for controlling air pollution in China. While previous studies have examined the costs and benefits of pollution control separately, this approach determines them together using an economy–environment model for China. We employ air dispersion simulations and population maps to calculate health damages due to air pollution. This provides estimates of incremental damages for industry output and fuel use. Based on these marginal damages, we simulate the effect of “green taxes” on the economy and show that the environmental benefits exceed the aggregate costs, ignoring adjustment costs for individual sectors.
