We propose a method to correct estimates from historical linked data for bias arising from type-I error--"false matches." We estimate the rate of false matching from the disagreement rate in characteristics that should agree across the two linked datasets. Combined with an understanding of the...

This paper develops linear estimators for structural and causal parameters in nonparametric,nonseparable models using panel data. These models incorporate unobserved, time-varying, individual heterogeneity, which may be correlated with the regressors. Estimation is based on an approximation of...

This survey discusses the recent causal panel data literature. This recent literature has focused on credibly estimating causal effects of binary interventions in settings with longitudinal data, with an emphasis on practical advice for empirical researchers. It pays particular attention to...

Environmental policy is increasingly concerned with measuring emissions resulting from local changes to electricity consumption. These marginal emissions are challenging to measure because electricity grids encompass multiple locations and the information available to identify the effect of each...

We study identification in a binary choice panel data model with a single predetermined binary covariate (i.e., a covariate sequentially exogenous conditional on lagged outcomes and covariates). The choice model is indexed by a scalar parameter θ, whereas the distribution of unit-specific...

Theoretical rationales for employer-provided pensions often focus on their ability to increase employee effort and selectively retain quality workers. We test these hypotheses using rich administrative data on public school teachers around the pension-eligibility threshold. When teachers cross...

This paper studies the use of mobile crisis response teams--a non-uniformed pair consisting of a mental health worker and a medic--as a component of emergency response to 911 calls. We provide the first evaluation of the longest-running program in the United States, Crisis Assistance Helping Out...

Information frictions--where a worker and her current employer know more about the worker's productivity than prospective employers--have complex equity-efficiency implications in the teacher labor market. Reducing information frictions may make it easier for effective teachers to move to their...

Public service reforms often provoke political backlash. Can they also yield political benefits for the politicians who champion them? We study a Wisconsin law that weakened teachers' unions and liberalized pay, prompting mass protests. Exploiting its staggered implementation across school...

When an employee expects repeated evaluation and performance incentives over time, the potential future rewards create an incentive to invest in building relevant skills. Because new skills benefit job performance, the effects of an evaluation program can persist after the rewards end or even...
