with Siqi Zheng, Matthew E. Kahn: w21301
Urban China’s high levels of ambient air pollution both lowers quality of life and raises mortality risk. China’s wealthy have the purchasing power to purchase private products such as portable room air filters that allows them to offset some of the pollution exposure risk. Using a unique data set of Internet purchases, we document that households invest more in masks and air filter products when ambient pollution levels exceed key alert thresholds. Richer people are more likely to invest in air filters, which are much more expensive than masks. Our findings have implications for trends in inequality in human capital accumulation and in quality of life inequality in urban China.

|November 2013||The Evolving Geography of China's Industrial Production: Implications for Pollution Dynamics and Urban Quality of Life|
with Siqi Zheng, Ye Qi, Matthew E. Kahn: w19624
China's rapid economic growth has been fueled by industrialization and urbanization. Given its export focus, this industrialization was spatially concentrated in the coastal eastern cities. Over the last decade, a spatial transformation has taken place leading to a deindustrialization of the rich coastal cities and sharp industrial growth in the inland cities. This survey examines recent work that studies the economic geography of industrial production, per-capita income, pollution and quality of life in China's cities. We focus on the interaction between firms, local governments and the central government that together determine the new economic geography of industry and pollution within China.
