Alan Woodward, Andrew Rogoyski
A small number of firms based in two states produce the most capable frontier AI models. The governments of those states have shown both the legal power and the political will to d…
Double/Debiased Machine Learning for Continuous Treatment Effects in Panel Data with Endogeneity
Peikai Wu, Kuan Sun, Zhiguo Xiao
We propose a double/debiased machine learning framework to estimate average derivative effects in nonparametric panel models with two-way fixed effects. It extends instrumental var…
Difference-in-Differences Under Network Interference
Kuan Sun, Zhiguo Xiao
This paper develops doubly robust estimators for direct (DATT) and spillover (SATT) average treatment effects on the treated in network-based difference-in-differences (DiD) design…
Causal Inference in Panel Data with a Continuous Treatment
Zhiguo Xiao, Peikai Wu
This paper proposes a framework that incorporates the two-way fixed effects model as a special case to conduct causal inference with a continuous treatment. Treatments are allowed…
