Timing of predictions in dynamic cheap talk: Experts vs. quacks
Smirnov, Aleksei; Starkov, Egor - 2019
of privately known competence, who cares about his reputation, chooses the timing of the forecast regarding the outcome …. Further, any report hurts the forecaster's reputation in the short run, with later reports incurring larger penalties. The … reputation of a silent forecaster, on the other hand, gradually improves over time. …

Community structure and market outcomes: A repeated games in networks approach
Fainmesser, Itay P. - 2010
Consider a large market with asymmetric information, in which sellers choose whether to cooperate or deviate and cheat their buyers, and buyers decide whether to re-purchase from different sellers. We model active trade relationships as links in a buyer-seller network and suggest a framework for...

Health care reform and the number of doctor visits: An econometric analysis
Winkelmann, Rainer - 2002
The paper evaluates the German health care reform of 1997, using the individual number of doctor visits as outcome measure and data from the German Socio- Economic Panel for the years 1995-1999. A number of modified count data models allow to estimate the effect of the reform in different parts...

Distributional comparative statics with heterogeneous agents
Hefti, Andreas - 2016
We propose a formal way to systematically study the differential effects of exogenous shocks in economic models with heterogeneous agents. Our setting applies to models that can be rephrased as "competition for market shares" in a broad sense. We show that even in presence of any number of...

Cycling and Categorical Learning in Decentralized Adverse Selection Economies
Jehiel, Philippe; Mohlin, Erik - 2021
We study learning in a decentralized pairwise adverse selection economy, where buyers have access to the quality of traded goods but not to the quality of non- traded goods. Buyers categorize ask prices in order to predict quality as a function of ask price. The categorization is endogenously...

Instability of belief-free equilibria
Heller, Yuval - 2017
Various papers have presented folk theorem results for repeated games with private monitoring that rely on belief-free equilibria. I show that these equilibria are not robust against small perturbations in the behavior of potential opponents. Specifically, I show that essentially none of the...

The endowment effect as blessing
Frenkel, Sivan; Heller, Yuval; Teper, Roee - 2017
We study the idea that seemingly unrelated behavioral biases can coevolve if they jointly compensate for the errors that any one of them would give rise to in isolation. We suggest that the "endowment effect" and the "winner's curse" could have jointly survived natural selection together. We...

Optimal mechanisms for an auction mediator
Matros, Alexander; Zapechelnyuk, Andriy - 2010
We consider a dynamic auction environment with a long-lived seller and short-lived buyers mediated by a third party. A mediator has incomplete information about traders' values and selects an auction mechanism to maximize her expected revenue. We characterize mediator-optimal mechanisms and show...

Competition of e-commerce intermediaries
Matros, Alexander; Zapechelnyuk, Andriy - 2010
In e-commerce, where information collection is essentially costless and geographic location of traders matters very little, fierce competition between providers of similar services is expected. We consider a model where two e-commerce intermediaries (internet shops) compete for sellers. We show...

Ex-post regret learning in games with fixed and random matching: The case of private values
Saran, Rene; Serrano, Roberto - 2010
In contexts in which players have no priors, we analyze a learning process based on ex-post regret as a guide to understand how to play games of incomplete information under private values. The conclusions depend on whether players interact within a fixed set (fixed matching) or they are...
