We show that capital controls have large adverse effects on misallocation, exports and welfare using a dynamic Melitz-OLG model with heterogeneous firms, monopolistic competition, endogenous trade participation and collateral constraints. Static effects increase misallocation by reducing...

How should industrial policies be directed to reduce distortions and foster economic development? We study this question in a multi-sector model with technology adoption, where the production of goods and modern technologies features rich network structures. We provide simple formulas for the...

We analyze how output and wages behave under different scenarios for technological progress that may culminate in Artificial General Intelligence (AGI), defined as the ability of AI systems to perform all tasks that humans can perform. We assume that human work can be decomposed into atomistic...

This paper examines the impact of roads on structural transformation and business composition theoretically and empirically. We develop a two-sector model of regional trade with endogenous firm entry that highlights two opposing forces. \textit{Ceteris paribus} lower trade costs in...

Women's contribution to the economy has been markedly underestimated in predominantly agricultural societies, due to their widespread involvement in unpaid agricultural work. Combining data from the US Census and several early sources, we create a consistent measure of male and female employment...

To fill the knowledge gap that previous studies ignore either housing or internal urban structure and to enable better fit with important stylized facts, we construct a two-sector optimal growth model of housing where housing is produced by land and housing structure/household durables. We...

Transformative technologies like generative artificial intelligence promise to accelerate productivity growth across many sectors, but they also present new risks from potential misuse. We develop a multi-sector technology adoption model to study the optimal regulation of transformative...

This paper asks whether increasing productivity in the electricity sector can yield larger long-run GDP gains than suggested by electricity's small share of aggregate economic activity. We answer this question using a dynamic multi-sector model in which electricity is a strong complement to...

We investigate the short- and long-term effects of a natural gas boom in an economy where energy can be produced with coal, natural gas, or clean sources and the direction of technology is endogenous. In the short run, a natural gas boom reduces carbon emissions by inducing substitution away...

This paper studies the evolution of China's production and trade patterns during its integration into the global economy. We document and explain new facts concerning changes in production and exports at the industry and firm levels using microdata and a quantitative Ricardian and...
