Despite widespread use in online transactions, rating systems only provide summary statistics of buyers' diverse opinions at best. To investigate the consequences of this coarse form of information aggregation, we consider a dynamic lemons market in which buyers share their evaluations...

We study a signaling game where agents signal their type by choosing when to quit pursuing an uncertain project. High types observe news about project quality and quit when bad news arrives. This creates opportunities for low types who do not observe any news to mimic high types by quitting...

The class of double-crossing preferences, where signaling is cheaper for higher types than for lower types at low signaling levels and the opposite is true at high signaling levels, underlines the phenomenon of countersignaling. We show that under the D1 refinement, the equilibrium signaling...

We introduce behavioral diversity to an otherwise standard signaling model, in which a fraction of agents choose their signaling actions according to an exogenous distribution. These behavioral agents provide opportunities for strategic low-type agents to successfully emulate higher types in...

Auctions are a popular and prevalent form of trading mechanism, despite the restriction that the seller cannot price-discriminate among potential buyers. To understand why this is the case, we consider an auction-like environment in which a seller with an indivisible object negotiates with two...

In many facets of life, we often face competition with a multilayered structure in which different levels of competition take place simultaneously. In this paper, we propose a new class of tournament models, called multilayered tournaments, to capture this type of competitive environment. Among...

It is often touted that decisiveness is one of the most important qualities to be possessed by leaders, broadly defined. To see how and why decisiveness can be a valuable asset in organizations, we construct a model of strategic information transmission where: (i) a decision maker solicits...
