More extreme heat events are expected under climate change, posing threats to food production as well as the lives of agriculture-dependent rural households. Using a detailed panel of rural households in an agricultural region of China, we find extreme heat substantially decreases crop...

One of the perceived advantages of difference-in-differences (DiD) methods is that they do not explicitly restrict how units select into treatment. However, when justifying DiD, researchers often argue that the treatment is "quasi-randomly" assigned. We investigate what selection mechanisms are...

This paper uses unique data on daily air pollution concentrations over the period 2001-2010 to test for manipulation in self-reported data by Chinese cities. First, we employ a discontinuity test to detect evidence consistent with data manipulation. Then, we propose a panel matching approach to...
