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 …

A designer commits to a signal distribution that is informative about a payoff-relevant state.
Conditional upon the privately observed signals, agents take actions that affect their payoffs …

The analysis of economies where information is imperfect and asymmetric has given rise to
a revolution in economics (Stiglitz, 2002, 2020). Longstanding fundamental results such as …

A sender chooses ex ante how information will be disclosed ex post. A receiver obtains
public information and information disclosed by the sender. Then he takes one of two …

This paper gives a simple proof of Blackwell's theorem on the ranking of information
structures. The proof extends naturally to environments where information arrives over time …

There has been a recent surge of interest in the role of information in strategic interactions.
Much of this work seeks to understand how the realized equilibrium of a game is influenced …

This paper characterizes the social value of information in Bayesian games with symmetric
quadratic payoff functions and normally distributed public and private signals. The main …

Many emerging problems involve teams of agents taking part in a game. Such problems
require a stochastic analysis with regard to the correlation structures among the agents …

Static reduction of information structures is a method that is commonly adopted in stochastic
control, team theory, and game theory. One approach entails change of measure arguments …

Which information structures are more effective at eliminating first-and higher-order
uncertainty and hence at facilitating efficient play in coordination games? We consider a …
