We enrich the Crawford and Sobel (1982) model of strategic communication between an informed sender and an uninformed receiver by adding repeated interactions and voluntary transfer payments. Transfers play two roles here: they incentivise decision-making and signal information. Although full...

We enrich a cheap-talk game between an informed sender and an uninformed receiver by adding repeated interactions and voluntary transfer payments. Transfers play two roles here: they motivate the receiver's decision-making and signal the sender's information. Although full separation can always...

An uninformed sender designs a mechanism that discloses information about her type to a privately informed receiver, who then decides whether to act. I impose a single-crossing assumption, so that the receiver with a higher type is more willing to act. Using a linear programming approach, I...

A sender chooses ex ante how her information will be disclosed to a privately informed receiver who then takes one of two actions. The sender wishes to maximize the probability that the receiver takes the desired action. The sender faces an ex ante quantity-quality tradeoff: sending positive...

We present a unified duality approach to Bayesian persuasion. The optimal dual variable, interpreted as a price function, is shown to be a super-gradient of the concave closure of the objective function at the prior belief. Under regularity conditions, our general duality result implies known...

Growing evidence suggests that many social and economic networks are scale free in that their degree distribution P(d) is approximately proportional to d^{-γ}. The most widespread explanation for this phenomenon is a random network formation process with preferential attachment. For a general...

At an exogenous deadline, Receiver must take an action, the payoff of which depends on Sender's private binary type. Sender privately observes whether and when an opportunity to start a public flow of information about her type arrives. She then chooses when to seize this opportunity. Starting...

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 actions. The sender wishes to maximize the probability that the receiver takes the desired action. I show that the sender...

We study a communication game between an informed sender and an uninformed receiver with repeated interactions and voluntary transfers. Transfers motivate the receiver's decision‐making and signal the sender's information. Although full separation can always be supported in equilibrium,...
