We provide an econometric framework for estimating a game of simultaneous entry and
pricing decisions while allowing for correlations between unobserved cost and demand …

We provide an introduction to the estimation of discrete choice models when choice sets are
heterogeneous and unobserved to the econometrician. We survey the two most popular …

We estimate a model of route‐level competition between airlines who choose whether to
offer nonstop or connecting service before setting prices. Airlines have full information about …

This paper studies the impact of competition on quality provision in the US airline industry
exploiting a novel source of exogenous variation in competition. While mergers among …

Merger simulations focus on the price changes that result once previously independent
competitors set prices jointly and other market participants respond. We consider the …

We develop a two-stage game in which competing airlines first choose the networks of
markets to serve in the first stage before competing in price in the second stage. Spillovers in …

I document the evolution of market power in the US airline industry for the period 1990: Q1-
2019: Q4. I recover estimates of markups, defined as the ratio of price to marginal cost, at the …

We develop an empirical framework to identify and estimate the effects of treatments on
outcomes of interest when the treatments are the result of strategic interaction (eg …

In this paper, we provide an introduction to the problems that arise in estimating discrete
choice models when choice sets are heterogeneous and unobserved to the econometrician …

I examine how incumbent airlines adjust their departure times in response to the threat of
entry by Southwest Airlines. I find that incumbents space their flights more evenly throughout …
