We constructed an Actuary Climate Index to measure extreme weather risks in China. Analyzing macroeconomic data through a structural vector auto-regression model suggests that a negative weather shock leads to persistently low GDP and credit obtained by non-financial firms. In our regression...

We quantify the economic costs of air pollution associated with drug expenditures. First, following a 1% increase in the annual average of PM2.5, the combined expenditures on respiratory, cardiovascular, and antitumor drugs are predicted to rise by an amount equivalent to 1.81% of the annual per...

In a multi-product Melitz model, we demonstrate that after a drop in domestic trade costs, the cost savings on the shipping of domestic intermediate inputs dominate the pressure from increased competition, thus aiding surviving domestic firms in increasing the number of export varieties. The...

In a trade model incorporating within-firm productivity differences in intermediate products, we show that specialization in the production of intermediate products enabled by decreased trade costs can reduce firm-level emissions. Using firm-level data from China (1998-2012), we provide...

Exploiting a change in policy governing the entry of foreign direct investment (FDI) in 2002, we apply the difference-in-differences model to estimate the effect of FDI on the product scope of domestic Chinese firms. In industries that experienced relaxation in FDI regulations, the average...

We constructed an Actuary Climate Index to measure extreme weather risks in China. Analyzing macroeconomic data through a structural vector auto-regression model suggests that a negative weather shock leads to persistently low GDP and credit obtained by non-financial firms. In our regression...

We develop a stylized trade model showing that lower trade costs can reduce firm-level emissions by encouraging firms to specialize in their most productive intermediate products. This mechanism operates through changes in within-firm product composition rather than industry-level reallocation....

In the current study, we document a steady rise in the share of renewable energy projects in China's outward direct investment (ODI) in the energy sector. We examine the driving forces and find that both host country's environmental regulation and financial factors has generated different or...
