We study the effect of information provision on avoidance behavior, using China’s roll-out of air pollution information as a quasi-natural experiment. With a unique dataset of high-frequency mask purchase transactions, our difference-in-differences estimates show that the provision of air...

We study the effect of information provision on avoidance behavior, using China's staggered roll-out of air pollution information and a unique dataset of high-frequency mask purchase transactions. Employing a generalized difference-in-differences approach, we estimate that the provision of air...

Geographical distance constitutes friction of searching research collaborators. Taking advantage of a quasi-natural experiment featured by recently connected High-Speed Railway (HSR) lines in China, this paper seeks to identify the impact of a substantial improvement in intercity transportation...
