Abstract: 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 entry
decisions across markets are allowed, which accrue on the demand, marginal cost, and fixed
cost sides. We show that the second-stage parameters are point identified, and we design a
tractable procedure to set identify the first-stage parameters and to conduct inference. Further,
we estimate the model using data from the domestic US airline market and find significant
spillovers in entry. In a counterfactual exercise, we evaluate the 2013 merger between American
Airlines and US Airways. Our results highlight that spillovers in entry and post-merger network
readjustments play an important role in shaping post-merger outcomes.
