Missing Data in Asset Pricing Panels
Freyberger, Joachim; Höppner, Björn; Neuhierl, Andreas; … - National Bureau of Economic Research - 2022
Missing data for return predictors is a common problem in cross sectional asset pricing. Most papers do not explicitly discuss how they deal with missing data but conventional treatments focus on the subset of firms with no missing data for any predictor or impute the unconditional mean. Both...

Identification of Non-Additive Fixed Effects Models : Is the Return to Teacher Quality Homogeneous?
Hahn, Jinyong; Singleton, John D.; Yildiz, Neşe - National Bureau of Economic Research - 2023
Panel or grouped data are often used to allow for unobserved individual heterogeneity in econometric models via fixed effects. In this paper, we discuss identification of a panel data model in which the unobserved heterogeneity both enters additively and interacts with treatment variables. We...

A Practical Guide to Endogeneity Correction Using Copulas
Qian, Yi; Koschmann, Anthony; Xie, Hui - National Bureau of Economic Research - 2024
Causal inference is of central interests in many empirical applications yet often challenging because of the presence of endogenous regressors. The classical approach to the problem requires using instrumental variables that must satisfy the stringent condition of exclusion restriction. At the...

A Local Projections Approach to Difference-in-Differences Event Studies
Dube, Arindrajit; Girardi, Daniele; Jordà, Òscar; … - National Bureau of Economic Research - 2023
Many of the challenges in the estimation of dynamic heterogeneous treatment effects can be resolved with local projection (LP) estimators of the sort used in applied macroeconometrics. This approach provides a convenient alternative to the more complicated solutions proposed in the recent...

Distortions, Producer Dynamics, and Aggregate Productivity : A General Equilibrium Analysis
Ayerst, Stephen; Brandt, Loren; Restuccia, Diego - National Bureau of Economic Research - 2023
The expansion in farm size is an important contributor to agricultural productivity in developed countries, but the reallocation process is hindered in less developed economies. How do distortions to factor reallocation affect farm dynamics and agricultural productivity? We develop a model of...

The Characteristics and Geographic Distribution of Robot Hubs in U.S. Manufacturing Establishments
Brynjolfsson, Erik; Buffington, Catherine; Goldschlag, … - National Bureau of Economic Research - 2023
We use data from the Annual Survey of Manufactures to study the characteristics and geography of investments in robots across U.S. manufacturing establishments. We find that robotics adoption and robot intensity (the number of robots per employee) is much more strongly related to establishment...

Where Have All the "Creative Talents" Gone? Employment Dynamics of US Inventors
Akcigit, Ufuk; Goldschlag, Nathan - National Bureau of Economic Research - 2023
How are inventors allocated in the US economy and does that allocation affect innovative capacity? To answer these questions, we first build a model of creative destruction where an inventor with a new idea has the possibility to work for an entrant or incumbent firm. If the inventor works for...
