Most countries exhibit large and persistent geographical differences in wages, income, and
unemployment rates. A growing class of place-based policies attempts to address these …

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 …

We study treatment-effect estimation using panel data. The treatment may be non-binary,
non-absorbing, and the outcome may be affected by treatment lags. We make a parallel …

Many studies use shift-share (or “Bartik”) instruments, which average a set of shocks with
exposure share weights. We provide a new econometric framework for shift-share …

We develop, estimate, and test a tractable general equilibrium model of oligopsony with
differentiated jobs and concentrated labor markets. We estimate key model parameters by …

This article analyzes how patent-induced shocks to labor productivity propagate into worker
compensation using a new linkage of US patent applications to US business and worker tax …

We quantify the amount of spatial misallocation of labor across US cities and its aggregate
costs. Misallocation arises because high productivity cities like New York and the San …

The credibility revolution in empirical economics has led researchers to set up more
transparent (quasi-) experimental research designs. This shift has increased the policy …

This article studies the effect of corporate and personal taxes on innovation in the United
States over the twentieth century. We build a panel of the universe of inventors who patented …

We quantify how sensitive is migration by star scientists to changes in personal and
business tax differentials across states. We uncover large, stable, and precisely estimated …
