We study dynamic signaling in a game of stochastically evolving stakes. Our motivating example is dynamic limit pricing in markets with persistent demand shocks. An incumbent is privately informed about its costs, high or low, and can deter a potential entrant by setting prices strategically....

We find that weekend, holiday and overnight trading breaks generate excessive perceived risk in the option markets, presumably due to asymmetric information, which, in turn, encourages uninformed option traders to postpone trading. This perceived risk subsides after two days accompanied by an...

Do public policy signals improve the alignment of market outcomes with economic fundamentals? Existing work contends that, when individual players have an incentive to coordinate their actions, public policy signals could steer these actions away from the fundamentals. We argue that such a...

The idea that information frictions amplify business cycles is hard to evaluate because information is not easily measured. We propose a quantifiable information friction that amplifies output fluctuations. In our simple model of decentralized trade, income dispersion measures uncertainty about...

Sudden big price changes are followed by periods of high and persistent volatility. I develop a tractable dynamic rational expectations model consistent with this observation. An infinity of agents possess dispersed information about future dividends and trade in centralized markets. Information...

The ad hoc Black-Scholes (AHBS) model is one of the most widely used option valuation models among practitioners models. The main contribution of this study is methodological. We have two main results: (1) we make the empirical observation that typically the call and put sneers are discontinuous...

We propose and estimate a model of endogenous informed trading that is a hybrid of the PIN and Kyle models. When an informed trader trades optimally, both returns and order flows are needed to identify information asymmetry parameters. Empirical relationships between parameter estimates and...

The model of Foster-Viswanathan (1990, FV) predicts that information heterogeneity among market participants generates patterns in volume, trading costs and volatility. In the Italian Treasury bond market, periodic information asymmetry is related to the arrival of block orders from...

An overlapping generations model is set up in this paper to analyze social security policy in a representative democracy with asymmetric information. The model considers not only redistribution between generations but also redistribution within generations according to individual labor incomes....
