We study the existence of efficient auctions in private value settings in which some bidders form their expectations about the distribution of their competitor's bids based on the accessible data from past similar auctions consisting of bids and ex post values. We consider steady states in such...

Motivated by the growing discussion on the resemblance of multilevel marketing schemes to pyramid scams, we compare the two phenomena based on their underlying compensation structures. We show that a company can design a pyramid scam to exploit a network of agents with coarse beliefs and that...

I consider multi-round cheap talk communication environments in which, after a lie, the informed party has no memory of the content of the lie.

The paper investigates social-learning when the information structure is not commonly known. Individuals repeatedly interact in social-learning settings with distinct information structures. In each round of interaction, they use their experience gained in past rounds to draw inferences from...
