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...

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...

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...

Firms in developing countries often identify electricity as a major constraint to operations. Decentralized renewable energy sources could help alleviate these constraints. We investigate whether electrification in Nepal -- via microhydro plants and their mini-grids -- helped grow the...

Electricity theft occurs when individuals cannot be excluded from accessing services. We study the impacts of an infrastructure upgrade in Karachi, Pakistan -- converting bare distribution wires to aerial bundled cables (ABCs) -- that was intended to prevent illegal connections. ABCs reduced...
