Preprint
In persuasion problems where the receiver's action is one-dimensional and his utility is single-peaked, optimal signals are characterized by duality, based on a first-order approach to the receiver's problem. A signal is optimal if and only if the induced joint distribution over states and actions is supported on a compact set (the contact set) whe...
Article
We consider a Bayesian persuasion problem where a sender's utility depends only on the expected state. We show that upper censorship that pools the states above a cutoff and reveals the states below the cutoff is optimal for all prior distributions of the state if and only if the sender's marginal utility is quasi‐concave. Moreover, we show that it...
Preprint
We present a unified duality approach to Bayesian persuasion. The optimal dual variable, interpreted as a price function, is shown to be a supergradient of the concave closure of the objective function at the prior belief. Under regularity conditions, our general duality result implies known results for the case when the objective function depends...
Preprint
A principal can restrict an agent's information (the persuasion problem) or restrict an agent's discretion (the delegation problem). We show that these problems are generally equivalent - solving one solves the other. We use tools from the persuasion literature to generalize and extend many results in the delegation literature, as well as to addres...
Preprint
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, partial or complete pooling is optimal if the receiver's decis...
Article
Sender, who is either good or bad, wishes to look good at an exogenous deadline. Sender privately observes if and when she can release a public flow of information about her private type. Releasing information earlier exposes to greater scrutiny, but signals credibility. In equilibrium bad Sender releases information later than good Sender. We find...

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 characterize optimal information disclosure and provide co...

We study persuasion mechanisms in linear environments. A receiver has a private type and chooses between two actions. A sender designs a persuasion mechanism or an experiment to disclose information about a payoff‐relevant state. A persuasion mechanism conditions information disclosure on the receiver's report about his type, whereas an experiment...
Article
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 separation can be 'frictionlessly' attained in equilibri...
Article
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 the information flow earlier exposes to greater scrutin...
Article
We present two new findings based on annual antipsychotic US prescribing data from IMS Health on 2867 psychiatrists who wrote 50 or more prescriptions in 2007. First, many of these psychiatrists have prescription patterns that are statistically significantly different than random draws from national market shares for prescriptions by psychiatrists....
Article
This article studies a principal-agent problem where the only commitment for the uninformed principal is to restrict the set of decisions she makes following a report by the informed agent. We show that an ex ante optimal equilibrium for the principal corresponds to a finite partition of the state space, and each retained decision is ex post subopt...
Article
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 optimally discloses only whether the receivers utility i...
Article
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 messages more often (in terms of the sender's information...
Article
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 version of such a process, we develop a class of GMM est...
Article
The first chapter studies optimal information revelation with one-sided asymmetric information. A sender chooses ex ante how her information will be revealed ex post. A receiver obtains both public information and information revealed by the sender, and then takes one of two actions. The sender wishes to maximize the probability that the receiver t...

Physicians prescribing drugs for patients with schizophrenia and related conditions are remarkably concentrated in their choice among antipsychotic drugs. In 2007 the single antipsychotic drug prescribed by a physician accounted for 66% of all antipsychotic prescriptions written by that physician. Which particular branded antipsychotic was the pres...

In this article, we study nationalizations in the oil industry around the world during 1960--2006. We show, both theoretically and empirically, that governments are more likely to nationalize when oil prices are high and when political institutions are weak. We consider a simple dynamic model of the interaction between a government and a foreign-ow...

This paper provides a survey on studies that analyze the macroeconomic effects of intellectual property rights (IPR). The first part of this paper introduces different patent policy instruments and reviews their effects on R&D and economic growth. This part also discusses the distortionary effects and distributional consequences of IPR protection a...
Article
An informed party (sender) wishes to maximize the probability that another party (receiver) takes one of two actions. The sender chooses ex ante how information will be revealed ex post. If the receiver does not have private information, then the sender optimally reveals only whether the receiver's utility is above a cuto at which the receiver is...
