A Design-Based Approach to Testing and Inference in (Quasi-)Experiments with Spillovers
Yechan Park
Economic policies rarely affect only their direct targets. To study these spillovers, researchers summarize who else was treated with a simple exposure measure, such as the share o…
Dynamically Consistent Statistical Decisions
Cheaheon Lim, Yechan Park
A large literature in econometrics proposes decision rules with optimality guarantees based on ex ante criteria, such as minimax regret. We develop a framework for analyzing the dy…
Choosing A Headline Estimand from Matching, DID, and Hybrid Designs: A Minimax-Regret Approach
Yechan Park, Yuya Sasaki
Researchers using panel data to estimate causal effects routinely choose among three approaches to using past outcomes: difference-in-differences (DID), conditioning on lagged outc…
Decomposition of Spillover Effects Under Misspecification: Pseudo-true Estimands and a Local-Global Extension
Yechan Park, Xiaodong Yang
To measure spillovers, researchers often summarize who else was treated with a simple measure, such as the share of treated neighbors. We study what the researcher estimates when t…
Matching Hybrid Difference in Differences
Yechan Park, Yuya Sasaki
Since LaLonde's (1986) seminal paper, there has been ongoing interest in estimating treatment effects using pre- and post-intervention data. Scholars have traditionally used experi…
The Informativeness of Combined Experimental and Observational Data under Dynamic Selection
Yechan Park, Yuya Sasaki
This paper addresses the challenge of estimating the Average Treatment Effect on the Treated Survivors (ATETS; Vikstrom et al., 2018) in the absence of long-term experimental data,…
