A Buyer Power Theory of Exclusive Dealing and Exclusionary Bundling

By Claire Chambolle and Hugo Molina

American Economic Journal: Microeconomics, August 2023

We develop a unified theory of exclusive dealing and exclusionary bundling. In a framework with two competing manufacturers that supply their product(s) through a monopolist retailer, we show that buyer power restores the profitability of such practices i...

Self-Reported Signaling

By Thomas Jungbauer and Michael Waldman

American Economic Journal: Microeconomics, August 2023

In many real-world settings, an action that affects the value of a product or service is self-reported rather than publicly observable. We investigate self-reporting when self-reports serve as a signal of sender productivity. In our model, a sender choose...

Disclosure in Markets for Ratings

By Ran Weksler and Boaz Zik

American Economic Journal: Microeconomics, August 2023

We study the implications of the disclosure regime of ratings on the level of information released to the public. Specifically, we compare mandatory and voluntary disclosure. We analyze a model where the potential issuers are initially endowed with homoge...

Competition for Attention and News Quality

By Heng Chen and Wing Suen

American Economic Journal: Microeconomics, August 2023

Over the past decades the number of news outlets has increased dramatically, but the quality of news products has declined. We propose a model to reconcile these facts where consumers' attention allocation decisions not only depend on but also affect news...

Working for References

By Samuel Häfner and Curtis R. Taylor

American Economic Journal: Microeconomics, August 2023

We analyze the incentive and welfare consequences of job references in a large economy marked by moral hazard, limited liability, exogenous job separation, and structural unemployment. In the firm-optimal equilibrium, employers provide references whenever...

Decreasing Impatience

By Christopher P. Chambers, Federico Echenique, and Alan D. Miller

American Economic Journal: Microeconomics, August 2023

We characterize decreasing impatience, a common behavioral phenomenon in intertemporal choice. Discount factors that display decreasing impatience are characterized through a convexity axiom for investments at fixed interest rates. Then we show that they ...

Bounds on a Slope from Size Restrictions on Economic Shocks

By Marco Stenborg Petterson, David Seim, and Jesse M. Shapiro

American Economic Journal: Microeconomics, August 2023

We study the problem of learning about the effect of one market-level variable (e.g., price) on another (e.g., quantity) in the presence of shocks to unobservables (e.g., preferences). We show that economic intuitions about the plausible size of the shock...

Influence Campaigns

By Evan Sadler

American Economic Journal: Microeconomics, August 2023

Firms and politicians, among others, invest heavily to influence people's opinions. Because peers influence one another, these efforts must account for social networks. Using a model of opinion dynamics with a non-degenerate steady state, I develop a new ...

Equilibrium Screening and Categorical Inequality

By Mogens Fosgerau, Rajiv Sethi, and Jörgen Weibull

American Economic Journal: Microeconomics, August 2023

We analyze equilibrium outcomes under costly screening of candidates from distinct categories. Candidates choose how much effort to invest in skill acquisition, and the screener decides how carefully to screen each candidate. Typically, there are multiple...

Bargaining over Treatment Choice under Disagreement

By Nabil I. Al-Najjar and Robert J. Gary-Bobo

American Economic Journal: Microeconomics, August 2023

A group of experts with different prior beliefs must choose a treatment. A dataset is made public and leads to revisions of beliefs. We propose a model where the experts' disagreements are resolved through bargaining, using the Nash bargaining solution. E...

Similarity Nash Equilibria in Statistical Games

By Rossella Argenziano and Itzhak Gilboa

American Economic Journal: Microeconomics, August 2023

A statistical game is a game in which strategic interaction is mediated via a binary outcome y, coupled with a prediction problem where a characteristic x of the game may be used to predict its outcome y based on past values of (x, y). In Similarity Nash ...

Keeping Up with "The Joneses": Reference-Dependent Choice with Social Comparisons

By Alastair Langtry

American Economic Journal: Microeconomics, August 2023

Keeping up with "The Joneses" matters. This paper examines a model of reference-dependent choice where reference points are determined by social comparisons. An increase in the strength of social comparisons, even by only a few agents, increases consumpti...

Judicial Mechanism Design

By Ron Siegel and Bruno Strulovici

American Economic Journal: Microeconomics, August 2023

This paper proposes a mechanism-design approach to study criminal justice systems. We derive properties of optimal mechanisms for two notions of welfare distinguished by their treatment of deterrence. These properties provide insights into the effects of ...

Bid Caps in Noisy Contests

By Qiang Fu, Zenan Wu, and Yuxuan Zhu

American Economic Journal: Microeconomics, August 2023

This paper studies optimal bid caps in a multiplayer noisy contest in which a higher bid does not guarantee a sure win. The bid cap can be either rigid or flexible. The former imposes outright bidding restrictions on players' bids, while the latter taxes ...

The Reversal Interest Rate

By Joseph Abadi, Markus Brunnermeier, and Yann Koby

American Economic Review, August 2023

The reversal interest rate is the rate at which accommodative monetary policy reverses and becomes contractionary for lending. We theoretically demonstrate its existence in a macroeconomic model featuring imperfectly competitive banks that face financial ...
