Bound by Ancestors : Immigration, Credit Frictions, and Global Supply Chain Formation

Choi, Jaerim; Hyun, Jay; Park, Ziho - National Bureau of Economic Research - 2023

structure of global supply chain networks. Using an instrumental variable strategy, combined with a novel dataset that links … firm-to-firm global supply chain information with a US establishment database and historical migration data, we find that … the co-ethnic networks formed by immigration have a positive causal impact on global supply chain relationships between …

Estimating Gravity from the Short to the Long Run : A Simple Solution to the 'International Elasticity Puzzle'

Anderson, James E.; Yotov, Yoto - National Bureau of Economic Research - 2022

for time-interval-varying depreciation-cum-adjustment. A time-varying trade elasticity in the structural gravity model is … implied. Our methods explain the 'international elasticity puzzle,' the discrepancy between trade elasticity estimates from … the trade literature and the international real business cycle literature.

Causal Effects in Matching Mechanisms with Strategically Reported Preferences

Bertanha, Marinho; Luflade, Margaux; Mourifié, Ismael - National Bureau of Economic Research - 2024

A growing number of central authorities use assignment mechanisms to allocate students to schools in a way that reflects student preferences and school priorities. However, most real-world mechanisms incentivize students to strategically misreport their preferences. In this paper, we provide an...

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...

Contamination Bias in Linear Regressions

Goldsmith-Pinkham, Paul; Hull, Peter; Kolesár, Michal - National Bureau of Economic Research - 2022

We study the interpretation of regressions with multiple treatments and flexible controls. Such regressions are often used to analyze stratified randomized control trials with multiple intervention arms, to estimate value-added (for, e.g., teachers) with observational data, and to leverage the...

Long Story Short : Omitted Variable Bias in Causal Machine Learning

Chernozhukov, Victor; Cinelli, Carlos; Newey, Whitney K.; … - National Bureau of Economic Research - 2022

We derive general, yet simple, sharp bounds on the size of the omitted variable bias for a broad class of causal parameters that can be identified as linear functionals of the conditional expectation function of the outcome. Such functionals encompass many of the traditional targets of...

Design-Based Identification with Formula Instruments : A Review

Borusyak, Kirill; Hull, Peter; Jaravel, Xavier - National Bureau of Economic Research - 2023

Many studies in economics use instruments or treatments which combine a set of exogenous shocks with other predetermined variables by a known formula. Examples include shift-share instruments and measures of social or spatial spillovers. We review recent econometric tools for this setting, which...

IV Methods Reconcile Intention-to-Screen Effects Across Pragmatic Cancer Screening Trials

Angrist, Joshua D.; Hull, Peter - National Bureau of Economic Research - 2023

Pragmatic cancer screening trials mimic real-world scenarios in which patients and doctors are the ultimate arbiters of treatment. Intention-to-screen (ITS) analyses of such trials maintain randomization-based apples-to-apples comparisons, but differential adherence (the failure of subjects...
