This paper reviews recent research on geography and trade. One of the key empirical
findings over the last decade has been the role of geography in shaping the distributional …

This paper develops a multi‐stage general‐equilibrium model of global value chains (GVCs)
and studies the specialization of countries within GVCs in a world with barriers to …

Using newly constructed spatially disaggregated data for London from 1801 to 1921, we
show that the invention of the steam railway led to the first large-scale separation of …

Public capital can play an important role in increasing long-run output and standards of
living. Because of nonrivalry in consumption, non excludability in use, or both, the private …

This paper estimates the effects of improving public transit infrastructure on city structure and

Coasts contain a disproportionate share of the world's population, reflecting historical
advantages, but environmental change threatens a reversal of coastal fortune in the coming …

We study optimal transport networks in spatial equilibrium. We develop a framework
