Heterogeneous Effects of Endogenous Treatments with Interference and Spillovers in a Large Network
Lin Chen, Yuya Sasaki
This paper studies the identification and estimation of heterogeneous effects of an endogenous treatment under interference and spillovers in a large single-network setting. We mod…
Benchmarking Fairness-aware Graph Neural Networks in Knowledge Graphs
Yuya Sasaki
Graph neural networks (GNNs) are powerful tools for learning from graph-structured data but often produce biased predictions with respect to sensitive attributes. Fairness-aware GN…
GMM and M Estimation under Network Dependence
Yuya Sasaki
This paper presents GMM and M estimators and their asymptotic properties for network-dependent data. To this end, I build on Kojevnikov, Marmer, and Song (KMS, 2021) and develop a…
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,…
A Bracketing Relationship for Long-Term Policy Evaluation with Combined Experimental and Observational Data
Yechan Park, Yuya Sasaki
Combining short-term experimental data with observational data enables credible long-term policy evaluation. The literature offers two key but non-nested assumptions, namely the la…
On real forms of Fermat hypersurfaces
Yuya Sasaki
In this paper, we compute the number of real forms of Fermat hypersurfaces for degree except the degree 4 surface case, and give explicit descriptions of them.
Nonnatural automorphisms of the Hilbert scheme of two points of some simple abelian variety
Yuya Sasaki
We construct nonnatural automorphisms of the Hilbert scheme of two points of some simple abelian variety preserving the big diagonal by considering automorphisms of the n-th produc…
