This article reviews recent advances in fixed effects estimation of panel data models for long
panels, where the number of time periods is relatively large. We focus on semiparametric …

We study the conditions under which it is possible to estimate regression quantiles by
estimating conditional means. The advantage of this approach is that it allows the use of …

This article provides a selective review of the recent literature on econometric models of
network formation. I start with a brief exposition on basic concepts and tools for the statistical …

An Advanced Guide to Trade Policy Analysis is a follow up to A Practical Guide to Trade
Policy Analysis. The Advanced Guide provides the most recent tools for analysis of trade …

Recent work on the effects of currency unions (CUs) on trade stresses the importance of
using many countries and years in order to obtain reliable estimates. However, for large …

We study the incidental parameter problem for the “three-way” Poisson Pseudo-Maximum
Likelihood (“PPML”) estimator recently recommended for identifying the effects of trade …

This paper estimates the effects of improving public transit infrastructure on city structure and
welfare. It develops a sufficient statistics approach common to a class of quantitative urban …

We propose a simple method to identify the effects of unilateral and non‐discriminatory trade
policies on bilateral trade within a theoretically consistent empirical gravity model …

In this survey we discuss the recent causal panel data literature. This recent literature has
focused on credibly estimating causal effects of binary interventions in settings with …

I introduce a model of undirected dyadic link formation which allows for assortative matching
on observed agent characteristics (homophily) as well as unrestricted agent‐level …
