Difference-in-Differences with Unequal Baseline Treatment Status
Tazhitdinova, Alisa; Vazquez-Bare, Gonzalo - National Bureau of Economic Research - 2023
We study a difference-in-differences (DiD) framework where groups experience unequal treatment statuses in the pre-policy change period. This approach is commonly employed in empirical studies but it contradicts the canonical model's assumptions. We show that in such settings, the standard DiD...

Two-way Fixed Effects and Differences-in-Differences Estimators with Several Treatments
Chaisemartin, Clément de; D'Haultfœuille, Xavier - National Bureau of Economic Research - 2022
We study two-way-fixed-effects regressions (TWFE) with several treatment variables. Under a parallel trends assumption, we show that the coefficient on each treatment identifies a weighted sum of that treatment's effect, with possibly negative weights, plus a weighted sum of the effects of the...

Production Function Estimation Using Subjective Expectations Data
Norris Keiller, Agnes; Paula, Áureo de; Van Reenen, John - National Bureau of Economic Research - 2024
Standard methods for estimating production functions in the Olley and Pakes (1996) tradition require assumptions on input choices. We introduce a new method that exploits (increasingly available) data on a firm's expectations of its future output and inputs that allows us to obtain consistent...

Cognitive Behavior Therapy Reduces Crime and Violence over 10 Years : Experimental Evidence
Blattman, Christopher; Chaskel, Sebastian; Jamison, … - National Bureau of Economic Research - 2022
In most societies, a small number of people commit the most serious violence. Short-term studies have shown that cognitive behavioral therapy (CBT) can reduce such antisocial behaviors. These behavior changes may be temporary, however, especially from therapy on its own. This is unsettled,...

Building Non-Discriminatory Algorithms in Selected Data
Arnold, David; Dobbie, Will; Hull, Peter - National Bureau of Economic Research - 2024
We develop new quasi-experimental tools to understand algorithmic discrimination and build non-discriminatory algorithms when the outcome of interest is only selectively observed. These tools are applied in the context of pretrial bail decisions, where conventional algorithmic predictions are...

Does School Choice Increase Crime?
Bibler, Andrew; Billings, Stephen B.; Ross, Stephen L. - National Bureau of Economic Research - 2023
School choice lotteries are an important tool for allocating access to high-quality and oversubscribed public schools. While prior evidence suggests that winning a school lottery decreases adult criminality, there is little evidence for how school choice lotteries impact non-lottery students who...

Machine Learning Can Predict Shooting Victimization Well Enough to Help Prevent It
Heller, Sara B.; Jakubowski, Benjamin; Jelveh, Zubin; … - National Bureau of Economic Research - 2022
This paper shows that shootings are predictable enough to be preventable. Using arrest and victimization records for almost 644,000 people from the Chicago Police Department, we train a machine learning model to predict the risk of being shot in the next 18 months. We address central concerns...

Officer-Involved : The Media Language of Police Killings
Moreno, Jonathan; Ouss, Aurélie; Bayer, Patrick J.; … - National Bureau of Economic Research - 2022
This paper studies the language used in television news broadcasts to describe police killings in the United States from 2013-19. We begin by documenting that the media is significantly more likely to use several language structures - e.g., passive voice, nominalization, intransitive verbs -...

Estimating the Impact of the Age of Criminal Majority : Decomposing Multiple Treatments in a Regression Discontinuity Framework
Mueller-Smith, Michael; Pyle, Benjamin; Walker, Caroline - National Bureau of Economic Research - 2023
This paper studies the impact of adult prosecution on recidivism and employment trajectories for adolescent, first-time felony defendants. We use extensive linked Criminal Justice Admin- istrative Record System and socio-economic data from Wayne County, Michigan (Detroit). Using the discrete age...
