We quantify the distributional effects of trade shocks in the U.S. through consumer prices (expenditure channel) and wages (earnings channel). A quantitative trade model links these channels to compositional differences in expenditures and earnings across household groups. New data reveal that...

A recent econometric literature shows two distinct paths for identification with shift-share instruments, leveraging either many exogenous shifts or exogenous shares. We present the core logic of both paths and practical takeaways via simple checklists. A variety of empirical settings illustrate...

What is the nature of the distributional effects of trade? This paper demonstrates conceptually and empirically the importance of “trade-induced horizontal inequality,” i.e. inequality brought about by trade shocks that occurs among workers with the same level of earnings prior to the shock....

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 instrumental variable (SSIV) regressions in which identification follows from the quasi-random assignment of shocks, while...

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 such designs in which identification follows from the quasi-random assignment of shocks, allowing exposure shares to be endogenous. This...

We develop new tools for estimating the causal effects of treatments or instruments that combine multiple sources of variation according to a known formula. Examples include treatments capturing spillovers in social and transportation networks, simulated instruments for policy eligibility, and...
