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...

We study inference in shift-share regression designs, such as when a regional outcome is regressed on a weighted average of observed sectoral shocks, using regional sector shares as weights. We conduct a placebo exercise in which we estimate the effect of a shift-share regressor constructed with...

A large literature exploits geographic variation in the concentration of immigrants to identify their impact on a variety of outcomes. To address the endogeneity of immigrants' location choices, the most commonly-used instrument interacts national inflows by country of origin with immigrants'...

Women in developed economies have made major inroads in labor markets throughout the past century, but remaining gender differences in pay and employment seem remarkably persistent. This paper documents long-run trends in female employment, working hours and relative wages for a wide...

We study how adverse economic shocks influence political outcomes in authoritarian regimes in strong states, by examining the 2013-2015 export slowdown in China. We exploit detailed customs data and the variation they reveal about Chinese prefectures' underlying exposure to the global trade...

This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations-innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation,...

How sensitive is long-run individual well-being to environmental conditions early in life? This paper examines the effect of weather conditions around the time of birth on the health, education, and socioeconomic outcomes of Indonesian adults born between 1953 and 1974. We link historical...

An industrial policy of subsidizing physical capital investment has been utilized in many countries in order to encourage export growth and spread economic development to outlying areas. For Israel, we possess a unique time series-cross section micro data set that details investment and its...

Several efficiency wage theories of wage determination have the property that identical workers are more productive in high wage industries and that the promotion of employment in high wage industries can increase GDP (and some measures of welfare). I argue that while policies to favor high wage...

Using extensive data on 1970 and 1987 urban characteristics, the paper analyzes changes in employment in specific manufacturing industries in cities between 1970 and 1987. Two sets of questions are the focus. First, what present or past characteristics of a city's economic environment are...
