Under the Kyoto Protocol, Clean Development Mechanism (CDM) is expected to facilitate the North-South knowledge spillovers for climate-friendly technologies. This paper examines the effects of this voluntary international climate cooperation on firm innovation and knowledge spillovers through...

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...
