csa2sls: A complete subset approach for many instruments using Stata

  title={csa2sls: A complete subset approach for many instruments using Stata},
  author={Seojeong Lee and Siha Lee and Julius Owusu and Youngki Shin},
. We develop a Stata command csa2sls that implements the complete subset averaging two-stage least squares (CSA2SLS) estimator in Lee and Shin [2021]. The CSA2SLS estimator is an alternative to the two-stage least squares estimator that remedies the bias issue caused by many correlated instruments. We conduct Monte Carlo simulations and confirm that the CSA2SLS estimator reduces both the mean squared error and the estimation bias substantially when instruments are correlated. We illustrate the…

Complete subset averaging with many instruments

We propose a two-stage least squares (2SLS) estimator whose first stage is the equal-weighted average over a complete subset with k instruments among K available, which we call the complete subset

Choosing the Number of Instruments

Properties of instrumental variable estimators are sensitive to the choice of valid instruments, even in large cross-section applications. In this paper we address this problem by deriving simple

Constructing Optimal Instruments by First-Stage Prediction Averaging

This paper considers model averaging as a way to construct optimal instruments for the two-stage least squares (2SLS), limited information maximum likelihood (LIML), and Fuller estimators in the

Estimating the Elasticity of Intertemporal Substitution When Instruments Are Weak

In the instrumental variables (IV) regression model, weak instruments can lead to bias in estimators and size distortion in hypothesis tests. This paper examines how weak instruments affect the

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

A new method of online inference for a vector of parameters estimated by the Polyak-Ruppert averaging procedure of stochastic gradient descent (SGD) algorithms is developed, which is fully operational with online data and is rigorously underpinned by a functional central limit theorem.

Automobile Prices in Market Equilibrium

This paper develops techniques for empirically analyzing demand and supply in differentiated product markets and then applies these techniques to the U.S. automobile industry. The authors' framework

About the authors

The livestock sector in Ethiopia is characterized by low productivity due to inadequate supply of affordable high-quality animal feed year-round, with more acute gaps in the drought-prone regions of
