Prolonged Learning and Hasty Stopping: The Wald Problem with Ambiguity

By Sarah Auster, Yeon-Koo Che, and Konrad Mierendorff

This paper studies sequential information acquisition by an ambiguity-averse decision-maker (DM), who decides how long to collect information before taking an irreversible action. The agent optimizes against the worst-case belief and updates prior by prio...

Gender Differences in Medical Evaluations: Evidence from Randomly Assigned Doctors

By Marika Cabral and Marcus Dillender

By Matthew Gentzkow, Jesse M. Shapiro, Frank Yang, and Ali Yurukoglu

American Economic Review, February 2024

Existing theories of media competition imply that advertisers will pay a lower price in equilibrium to reach consumers who multi-home across competing outlets. We generalize and extend this theoretical result and test it using data from television and soc...

Predicting Cooperation with Learning Models

By Drew Fudenberg and Gustav Karreskog Rehbinder

American Economic Journal: Microeconomics, February 2024

We use simulations of a simple learning model to predict cooperation rates in the experimental play of the indefinitely repeated prisoner's dilemma. We suppose that learning and the game parameters only influence play in the initial round of each supergam...

Social Connectedness and Information Markets

By Rachel Kranton and David McAdams

American Economic Journal: Microeconomics, February 2024

Innovation in Decentralized Markets: Technology versus Synthetic Products

By Marzena Rostek and Ji Hee Yoon

American Economic Journal: Microeconomics, February 2024

Advances in market-clearing technology for multiple assets and synthetic products present alternative ways to leverage complementarities and substitutabilities in asset payoffs. This paper compares their equilibrium and welfare effects. In competitive mar...

Exit Dilemma: The Role of Private Learning on Firm Survival

By Doruk Cetemen and Chiara Margaria

American Economic Journal: Microeconomics, February 2024

We study the exit of duopolists from a stochastically declining market. Firms privately learn about the market conditions from observing the stochastic arrival of customers, while exit decisions are publicly observed. A larger firm is more likely to have ...

A Random Reference Model

By Özgür Kibris, Yusufcan Masatlioglu, and Elchin Suleymanov

American Economic Journal: Microeconomics, February 2024

We provide two nested models of random reference-dependent choice in which the reference point is endogenously determined by random processes. Random choice behavior is due to random reference points, even though, from the decision-maker's viewpoint, choi...

Weighted Utility and Optimism/Pessimism: A Decision-Theoretic Foundation of Various Stochastic Dominance Orders

By Tao Wang and Ehud Lehrer

American Economic Journal: Microeconomics, February 2024

We show that a probability distribution likelihood ratio dominates another distribution if and only if, for every weighted utility function, the former is preferred over the latter. Likewise, a probability distribution hazard rate (or reverse hazard rate)...

Coordination in the Fight against Collusion

By Elisabetta Iossa, Simon Loertscher, Leslie M. Marx, and Patrick Rey

American Economic Journal: Microeconomics, February 2024

While antitrust authorities strive to detect, prosecute, and thereby deter collusive conduct, entities harmed by that conduct are also advised to pursue their own strategies to deter collusion. The implications of such delegation of deterrence have largel...

Constructive versus Toxic Argumentation in Debates

By Tymofiy Mylovanov and Andriy Zapechelnyuk

American Economic Journal: Microeconomics, February 2024

Two debaters address an audience by sequentially choosing their information strategies. We compare the setting where the second mover reveals additional information (constructive argumentation) with the setting where the second mover obfuscates the first ...

Anticompetitive Bundling When Buyers Compete

By Alexandre de Cornière and Greg Taylor

American Economic Journal: Microeconomics, February 2024

We study the profitability of bundling by an upstream firm that licenses technologies to downstream competitors and that faces competition for one of its technologies. In an otherwise standard "Chicago-style" model, the existence of downstream competition...

Intertemporal Altruism

By Felix Chopra, Armin Falk, and Thomas Graeber

American Economic Journal: Microeconomics, February 2024

Most prosocial decisions involve intertemporal trade-offs. Yet, the timing of prosocial utility flows is ambiguous and bypassed by most models of other-regarding preferences. We study the behavioral implications of the time structure of prosocial utility,...
