Generalizing the idea that price momentum can be explained by different levels of uncertainty inherent in the information structure, we implement signal-specific differences in uncertainty in a Kyle type model of strategic trading. We derive the equilibrium in a single-auction setting as well as...

In this paper the problem of optimal derivative design, profit maximization and risk minimization under adverse selection when multiple agencies compete for the business of a continuum of heterogenous agents is studied. In contrast with the principal-agent models that are extended within, here...

The current financial crisis is a crisis of theory as well. The dominant theory of financial markets, the efficient market hypothesis (EMH), states that in an efficient market the price of a financial asset reflects publicly available information about that asset. Competing theories, such as...

In this paper, we develop a model in which overconfident market participants and rational speculators trade against trend-chasers. We show that the growth and the burst of a financial bubble stem from positive feedback trading. However, the presence of overconfident traders and the risk aversion...

In this article we derive risk-neutral option price formulas for both plain-vanilla and exotic electricity futures derivatives on the basis of diverse arithmetic multi-factor Ornstein-Uhlenbeck spot price models admitting seasonality, while – in order to avoid “information...

This paper analyzes the welfare implications of information aggregation in a security-trading model where traders have both idiosyncratic endowment risk and asymmetric information about security payoffs. In the model a large market can be welfare-reducing --- i.e., the optimal market size is...

We consider the impact of mandatory information disclosure on bank safety in a spatial model of banking competition in which a bank's probability of success depends on the quality of its risk measurement and management systems. Under Basel II capital requirements, this quality is either fully or...

We analyse a Kyle-type continuous-time market model in which liquidity trading is correlated with a noisy public signal that is released continuously. We show that, in contrast to the previous literature, Kyle's lambda, the price sensitivity to the order flow, can even be nonmonotonic, depending...

We develop a model in which feedback effects from equity markets to firms' access to external finance allow uninformed traders to profit by short selling a firm's stock while going long on its competitors. Because this strategy distorts the investment incentives of the firm targeted by short...
