Synthetic Decomposition for Counterfactual Predictions

no code implementations11 Jul 2023 Nathan Canen, Kyungchul Song

Counterfactual predictions are challenging when the policy variable goes beyond its pre-policy support.

Estimating Dynamic Spillover Effects along Multiple Networks in a Linear Panel Model

no code implementations16 Nov 2022 Clemens Possnig, Andreea Rotărescu, Kyungchul Song

Spillover of economic outcomes often arises over multiple networks, and distinguishing their separate roles is important in empirical research.

Some Impossibility Results for Inference With Cluster Dependence with Large Clusters

no code implementations8 Sep 2021 Denis Kojevnikov, Kyungchul Song

When within-cluster observations satisfy the uniform central limit theorem, we also show that a sufficient condition for consistent $\sqrt{n}$-discrimination of the mean is that we have at least two large clusters.

The Law of Large Numbers for Large Stable Matchings

no code implementations2 Jan 2021 Jacob Schwartz, Kyungchul Song

In many empirical studies of a large two-sided matching market (such as in a college admissions problem), the researcher performs statistical inference under the assumption that they observe a random sample from a large matching market.

A Decomposition Approach to Counterfactual Analysis in Game-Theoretic Models

no code implementations17 Oct 2020 Nathan Canen, Kyungchul Song

Decomposition methods are often used for producing counterfactual predictions in non-strategic settings.

Counterfactual Analysis under Partial Identification Using Locally Robust Refinement

no code implementations31 May 2019 Nathan Canen, Kyungchul Song

In particular, within the identified set, some counterfactual predictions can exhibit more robustness than others, against local perturbations of the reduced forms (e. g. the equilibrium selection rule).

Limit Theorems for Network Dependent Random Variables

no code implementations4 Mar 2019 Denis Kojevnikov, Vadim Marmer, Kyungchul Song

This paper is concerned with cross-sectional dependence arising because observations are interconnected through an observed network.
