Canonical urban models postulate transportation cost as a key element in determining urban spatial structure. This paper examines how road rationing policies impact the spatial distribution of households using rich micro data on housing transactions and resident demographics in Beijing. We find...

Although entry regulation is ubiquitous across countries, comprehensive evaluations on the broad impacts of such regulations on firm dynamics and productivity are lacking. We address the key identification challenge of policy endogeneity by leveraging the staggered implementation of a pilot...

During 2013-2014, China launched a nationwide, real-time air quality monitoring and disclosure program, a watershed moment in the history of its environmental regulations. We present the first empirical analysis of this natural experiment by exploiting its staggered implementation across cities....

The social costs of pollution and climate change hinge critically on humans’ ability to adapt. Based on transaction records from the world’s largest payment network, this research compiles daily travel flows and documents that China’s rapid expansion of high-speed railways (HSR)...
