Industry-wide shocks can have heterogeneous impacts on firms' costs due to different firm characteristics. The heterogeneity of these impacts is crucial for understanding the pass-through of the shock because of its implications for strategic competition....

Second-Degree Price Discrimination by a Two-Sided Monopoly Platform

By Doh-Shin Jeon, Byung-Cheol Kim, and Domenico Menicucci

American Economic Journal: Microeconomics, May 2022

We study second-degree price discrimination by a two-sided monopoly platform. The incentive constraints of the agents on the value creation side may be in conflict with internalizing externalities on the value capture side, which may render pooling optima...

Group Hug: Platform Competition with User Groups

By Sarit Markovich and Yaron Yehezkel

American Economic Journal: Microeconomics, May 2022

We consider platform competition for small users and a user group. One platform enjoys a quality advantage and the other benefits from favorable beliefs. We study whether the group mitigates the users' coordination problem⁠—i.e., joining a low-quality...

An Index of Competitiveness and Cooperativeness for Normal-Form Games

By Thomas Demuynck, Christian Seel, and Giang Tran

American Economic Journal: Microeconomics, May 2022

We develop an index of competitiveness and cooperativeness that is based on the primitives of a normal-form game, i.e., players, strategies and payoffs. The index relies on the unique decomposition of a given game into a zero-sum game and a common interes...

Bad News Turned Good: Reversal under Censorship

By Aleksei Smirnov and Egor Starkov

American Economic Journal: Microeconomics, May 2022

Sellers often have the power to censor the reviews of their products. We explore the effect of these censorship policies in markets where some consumers are unaware of possible censorship. We find that if the share of such "naïve" consumers is not too la...

By Marika Cabral, Can Cui, and Michael Dworsky

American Economic Review, May 2022

Workers' compensation insurance, which provides no-fault coverage for work-related injuries, is mandatory in nearly all states. We use administrative data from a unique market without a coverage mandate to estimate the demand for workers' compensation ins...

By Gaurab Aryal, Manudeep Bhuller, and Fabian Lange

American Economic Review, May 2022

This paper considers the use of instruments to identify and estimate private and social returns to education within a model of employer learning. What an instrument identifies depends on whether it is hidden from, or transparent (i.e., observed) to, the e...

Multidimensional Auctions of Contracts: An Empirical Analysis

By Yunmi Kong, Isabelle Perrigne, and Quang Vuong

American Economic Review, May 2022

In this paper, we conduct a structural analysis of multi-attribute auctions of contracts with a general allocation rule when private information is multidimensional. Upon modeling bidders' contract value that accounts for their endogenous ex post actions,...

By Geoffroy de Clippel, Jack Fanning, and Kareen Rozen

American Economic Review, May 2022

We study bargaining over contingent contracts in problems where private information becomes public or verifiable when the time comes to implement the agreement. We suggest a simple, two-stage game that incorporates important aspects of bargaining. We char...

Macroeconomic Implications of COVID-19: Can Negative Supply Shocks Cause Demand Shortages?

By Veronica Guerrieri, Guido Lorenzoni, Ludwig Straub, and Iván Werning

American Economic Review, May 2022

Motivated by the effects of the COVID-19 pandemic, we present a theory of Keynesian supply shocks: shocks that reduce potential output in a sector of the economy, but that, by reducing demand in other sectors, ultimately push aggregate activity below pote...

Supply and Demand in Disaggregated Keynesian Economies with an Application to the COVID-19 Crisis

By David Baqaee and Emmanuel Farhi

American Economic Review, May 2022

We study supply and demand shocks in a disaggregated model with multiple sectors, multiple factors, input-output linkages, downward nominal wage rigidities, credit-constraints, and a zero lower bound. We use the model to understand how the COVID-19 cris...
