Technical Change and Superstar Effects: Evidence from the Rollout of Television

By Felix Koenig

American Economic Review: Insights, June 2023

Technical change that extends market scale can generate winner-take-all dynamics, with large income growth among top earners. I test this "superstar model" in the entertainer labor market, where the historic rollout of television creates a natural experim...

By Bingchao Huangfu and Heng Liu

American Economic Journal: Microeconomics, August 2023

This paper analyzes information spillover in a multi-good adverse selection model in which a privately informed seller trades two different goods in two different markets. Buyers learn the seller's information from both the market they participate in and ...

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...

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...

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

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...
