Start-up Search Costs

By David P. Byrne and Nicolas de Roos

Workhorse economic models used for studying the market impacts of search frictions assume constant search costs: individuals pay the same cost to obtain price information each time they search. This paper provides evidence on a new form of search costs: s...

Tractable Model of Dynamic Many-to-Many Matching

By Marcin Pęski

American Economic Journal: Microeconomics, May 2022

We develop a tractable, dynamic, and strategic model of many-to-many matching with payoff externalities across links. The joint dynamic surplus or certain second properties of individual utilities, like pay-off externalities, can typically be identified. ...

Friend-Based Ranking

By Francis Bloch and Matthew Olckers

American Economic Journal: Microeconomics, May 2022

We analyze the design of a mechanism to extract a ranking of individuals according to a unidimensional characteristic, such as ability or need. Individuals, connected on a social network, only have local information about the ranking. We show that a plann...

Optimal Nonlinear Pricing by a Dominant Firm under Competition

By Yong Chao, Guofu Tan, and Adam Chi Leung Wong

American Economic Journal: Microeconomics, May 2022

We consider a nonlinear pricing problem faced by a dominant firm competing with a minor firm. The dominant firm offers a general tariff first, and then the minor firm responds with a per-unit price, followed by a buyer choosing her purchases. By developin...

Transforming Ordinal Riskless Utility into Cardinal Risky Utility: A Comment on Chung, Glimcher, and Tymula (2019)

By Peter P. Wakker

American Economic Journal: Microeconomics, May 2022

Chung, Glimcher, and Tymula (2019) observed both consumers' choices over commodity bundles and choices under risk. They assumed a cardinal riskless utility function V representing consumer choices and a cardinal risky utility function U. The two were inco...

Intermediation and Steering: Competition in Prices and Commissions

By Tat-How Teh and Julian Wright

American Economic Journal: Microeconomics, May 2022

We explore the implications of steering by an informed profit-maximizing intermediary. The intermediary steers consumers by recommending firms, taking into account both the commissions firms offer and the prices they set. Such steering results in higher c...

Heterogeneous Impacts of Cost Shocks, Strategic Bidding, and Pass-Through: Evidence from the New England Electricity Market

By Harim Kim

American Economic Journal: Microeconomics, May 2022

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...
