SGMM: Stochastic Approximation to Generalized Method of Moments

no code implementations25 Aug 2023 Xiaohong Chen, Sokbae Lee, Yuan Liao, Myung Hwan Seo, Youngki Shin, Myunghyun Song

We introduce a new class of algorithms, Stochastic Generalized Method of Moments (SGMM), for estimation and inference on (overidentified) moment restriction models.

Optimal Delegation in Markets for Matching with Signaling

no code implementations16 Mar 2023 Seungjin Han, Alex Sam, Youngki Shin

This paper studies a delegation problem faced by the planner who wants to regulate receivers' reaction choices in markets for matching between receivers and senders with signaling.

Fast Inference for Quantile Regression with Tens of Millions of Observations

no code implementations29 Sep 2022 Sokbae Lee, Yuan Liao, Myung Hwan Seo, Youngki Shin

Big data analytics has opened new avenues in economic research, but the challenge of analyzing datasets with tens of millions of observations is substantial.

Statistical Treatment Rules under Social Interaction

no code implementations19 Sep 2022 Seungjin Han, Julius Owusu, Youngki Shin

In this paper we study treatment assignment rules in the presence of social interaction.

csa2sls: A complete subset approach for many instruments using Stata

no code implementations4 Jul 2022 Seojeong Lee, Siha Lee, Julius Owusu, Youngki Shin

We develop a Stata command $\texttt{csa2sls}$ that implements the complete subset averaging two-stage least squares (CSA2SLS) estimator in Lee and Shin (2021).

Monotone Equilibrium in Matching Markets with Signaling

no code implementations7 Sep 2021 Seungjin Han, Alex Sam, Youngki Shin

We introduce a notion of competitive signaling equilibrium (CSE) in one-to-one matching markets with a continuum of heterogeneous senders and receivers.

Fast and Robust Online Inference with Stochastic Gradient Descent via Random Scaling

1 code implementation6 Jun 2021 Sokbae Lee, Yuan Liao, Myung Hwan Seo, Youngki Shin

We develop a new method of online inference for a vector of parameters estimated by the Polyak-Ruppert averaging procedure of stochastic gradient descent (SGD) algorithms.

Exact Computation of Maximum Rank Correlation Estimator

no code implementations8 Sep 2020 Youngki Shin, Zvezdomir Todorov

In this paper we provide a computation algorithm to get a global solution for the maximum rank correlation estimator using the mixed integer programming (MIP) approach.

Complete Subset Averaging for Quantile Regressions

no code implementations6 Mar 2020 Ji Hyung Lee, Youngki Shin

We propose a novel conditional quantile prediction method based on complete subset averaging (CSA) for quantile regressions.
