First Price Auctions with General Information Structures : Implications for Bidding and Revenue
Bergemann, Dirk - 2015
This paper explores the consequences of information in sealed bid first price auctions. For a given symmetric and … Bayesian equilibrium for some information structure. In particular, we characterize maximum and minimum revenue across all … information structures when bidders may not know their own values, and maximum revenue when they do know their values. Revenue is …

Misinterpreting Others and the Fragility of Social Learning
Frick, Mira - 2019
We study to what extent information aggregation in social learning environments is robust to slight misperceptions of … others' characteristics (e.g., tastes or risk attitudes). We consider a population of agents who obtain information about the … first main result shows that even arbitrarily small amounts of misperception can generate extreme breakdowns of information …
