Abstract
Date: First version: June 2009, this version October 28, 2010. Preliminary results of this paper were FIRST presented at Chernozhukov's invited Cowles Foundation lecture at the Northern American meetings of the Econometric society in June of 2009. We thank seminar participants at Brown, Columbia, Harvard-MIT, the Dutch Econometric Study Group, Fuqua School of Business, and NYU for helpful comments. We also thank Denis Chetverikov, JB Doyle, and Joonhwan Lee for thorough reading of this paper and helpful feedback.

Double/debiased machine learning for treatment and structural parameters

TL;DR: In this article, the authors show that the impact of regularization bias and overfitting on estimation of the parameter of interest θ0 can be removed by using two simple, yet critical, ingredients: (1) using Neyman-orthogonal moments/scores that have reduced sensitivity with respect to nuisance parameters, and (2) making use of cross-fitting, which provides an efficient form of data-splitting.

Machine Learning: An Applied Econometric Approach

TL;DR: This work presents a way of thinking about machine learning that gives it its own place in the econometric toolbox, and aims to make them conceptually easier to use by providing a crisper understanding of how these algorithms work, where they excel, and where they can stumble.

Inference on Treatment Effects after Selection among High-Dimensional Controls

TL;DR: The authors proposed robust methods for inference about the effect of a treatment variable on a scalar outcome in the presence of very many regressors in a model with possibly non-Gaussian and heteroscedastic disturbances.

Sparse Models and Methods for Optimal Instruments with an Application to Eminent Domain

TL;DR: A fully data-driven method for choosing the user-specified penalty that must be provided in obtaining LASSO and Post-LASSO estimates is provided and its asymptotic validity under non-Gaussian, heteroscedastic disturbances is established.

High-Dimensional Methods and Inference on Structural and Treatment Effects

TL;DR: Using scanner datasets that record transaction-level data for households across a wide range of products, or text data where counts of words in documents may be wide range to text data, researchers are faced with a large set of potential variables formed by different ways of interacting and transforming the underlying variables.

Regression Shrinkage and Selection via the Lasso

TL;DR: A new method for estimation in linear models called the lasso, which minimizes the residual sum of squares subject to the sum of the absolute value of the coefficients being less than a constant, is proposed.

Instrumental variables regression with weak instruments

Douglas O. Staiger, +1 more
- 01 May 1997 - 
TL;DR: In this paper, the authors developed asymptotic distribution theory for instrumental variable regression when the partial correlation between the instruments and a single included endogenous variable is weak, here modeled as local to zero.

Weak Convergence and Empirical Processes

TL;DR: This chapter discusses Convergence: Weak, Almost Uniform, and in Probability, which focuses on the part of Convergence of the Donsker Property which is concerned with Uniformity and Metrization.

Testing for Weak Instruments in Linear IV Regression

TL;DR: This paper proposed quantitative definitions of weak instruments based on the maximum IV estimator bias, or the maximum Wald test size distortion, when there are multiple endogenous regressors, and tabulated critical values that enable using the first-stage F-statistic (or, for instance, the Cragg-Donald (1993) statistic) to test whether give n instruments are weak.

The Dantzig selector: Statistical estimation when p is much larger than n

TL;DR: In many important statistical applications, the number of variables or parameters p is much larger than the total number of observations n as discussed by the authors, and it is possible to estimate β reliably based on the noisy data y.
