This paper studies when introducing verifiable communication choices between agents in a cheap-talk benchmark setting, with social tie, is beneficial to welfare. In our model agents have two ways to communicate their private information: either through a costly verifiable information (hard) link...

We study the optimal size and composition of an advisory committee when shareholders differ in preferences and beliefs and strategically acquire and communicate information. If shareholders and management have similar objectives but disagree due to different beliefs, and information is cheap,...

Regulation to protect individuals from self-harm, such as euthanasia prohibitions and safety mandates, is widespread but controversial. Opponents and proponents are often believed to differ in their valuation of individual liberty. We model an authority's decision to constrain or inform a...

We propose a parsimonious model of information choice in a global coordination game of regime change that is used to analyze debt crises, bank runs or currency attacks. A change in the publicly available information alters the uncertainty about the behavior of other investors. Greater strategic...

We examine the system-wide effects of liquidity regulation on banks' balance sheets. In the general equilibrium model, banks have to hold liquid assets, and choose among illiquid assets varying in the extent to which they are difficult to value before maturity, e.g., structured securities. By...

We propose a parsimonious model of information choice in a global coordination game of regime change that is used to analyze debt crises, bank runs or currency attacks. A change in the publicly available information alters the uncertainty about the behavior of other investors. Greater strategic...

Within the context of games on networks S. Goyal (Goyal (2007), pg. 39) posed the following problem. Under any arbitrary but fixed topology, does there exist at least one pure Nash equilibrium that exhibits a positive relation between the cardinality of a player's set of neighbors and its...

This paper aims to study the impact of costly and private information acquisition in global games with applications in financial crisis (e.g. bank runs, currency crisis). While exogenous asymmetric information has been shown to select a unique equilibrium, we show that the endogenous costly...

We study the problem of optimal dynamic pricing for a monopolist selling a product to consumers in a social network. In the proposed model, the only means of spread of information about the product is via Word of Mouth communication; consumers' knowledge of the product is only through friends...
