Open-end mutual funds face redemptions by investors, but the sale of the underlying assets depends on the portfolio decision of asset managers. If asset managers use their cash holding as a buffer to meet redemptions, they can mitigate fire sales of the underlying asset. If they hoard cash in...

We illustrate the corrosive effect of even small amounts of adverse selection in an asset market and show how it can lead to the total breakdown of trade. The problem is the failure of "market confidence," defined as approximate common knowledge of an upper bound on expected losses. Small...

Each player in an infinite population interacts strategically with a finite subset of that population. Suppose each player?s binary choice in each period is a best response to the population choices of the previous period. When can behaviour that is initially played by only a finite set of...

We highlight a trade-off between speed (the rate at which behaviours propagate in the population) and resilience (the measure of initial adopters required for spreading) in models of threshold contagion: contagion is faster in networks where it is harder to initiate contagion. We derive various...

Some private-monitoring games, that is, games with no public histories, can have histories that are almost public. These games are the natural result of perturbing public monitoring games towards private monitoring. We explore the extent to which it is possible to coordinate continuation play in...

In a general interdependent preference environment, we characterize when two payoff types can be distinguished by their rationalizable strategic choices without any prior knowledge of their beliefs and higher order beliefs. We show that two payoff types are strategically distinguishable if and...

A game of incomplete information can be decomposed into a basic game and an information structure. The basic game defines the set of actions, the set of payoff states the payoff functions and the common prior over the payoff states. The information structure refers to the signals that the...

We characterize revenue maximizing mechanisms in a common value environment where the value of the object is equal to the highest of bidders’ independent signals. If the object is optimally sold with probability one, then the optimal mechanism is simply a posted price, with the highest...

A universal type space of interdependent expected utility preference types is constructed from higher-order preference hierarchies describing (i) an agent's (unconditional) preferences over a lottery space; (ii) the agent's preference over Anscombe-Aumann acts conditional on the unconditional...
