Equilibrium Effects in Complementary Markets: Electric Vehicle Adoption and Electricity Pricing

(with Pascal Heid and Mathias Reynaert)

Abstract (click to expand): The transition to electric vehicles (EVs) shifts the complementary market for passenger transport from oil to electricity. We develop and estimate a joint equilibrium model of the German electricity and automobile markets, emphasizing the timing of EV charging, as electricity generation costs and pollution vary intraday. Our results show that under Germany’s current electricity pricing scheme, EVs create a significant pecuniary externality: electricity expenses rise by €0.66 for every €1 spent charging. Exposing charging to wholesale price variation eliminates the pecuniary externality, makes EVs greener, and increases adoption—a triple dividend.

Price Competition and Endogenous Product Choice in Networks: Evidence from the US Airline Industry

(with Christian Bontemps and Cristina Gualdani)

Revise and Resubmit, Econometrica

Abstract (click to expand): 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.

The impact of price comparison tools on electricity retailer choices

(with Peter Gibbard)

Reject and Resubmit, RAND Journal of Economics

Abstract (click to expand): We estimate a structural model of electricity retailer choices accommodating various sources of consumer inertia, including inattention, limited information, switching costs, and product differentiation. The model disentangles the relative importance of different frictions. We estimate our model using individual-level data of all retailer switches and queries on a price comparison website in New Zealand. We find that price comparison tools strongly impact market structure and consumer surplus. However, mandating all consumers search for alternatives has stronger effects on market structure and consumer surplus gains. Our results help policymakers design policies that improve consumer choices and effective competition in retail markets.
