An information externality exists in the foreign exchange market due to the fact that traders play two partially conflicting roles: (i) each is a speculator and (ii) each is an information clearinghouse in that each intermediates own-customer orders which convey information. Profit maximization...

We propose a broad measure of liquidity for the overall financial market by exploiting its connection with the amount of arbitrage capital in the market and the potential impact on price deviations in US Treasurys. When arbitrage capital is abundant, we expect the arbitrage forces to smooth out...

A model of interest rate movements in response to new information on the money stock is developed.The model, which incorporates several earlier approaches as special cases, makes explicit the manner in which estimated interest rate responses to money surprises depend on the relative variances of...

This paper reconsiders the Phelps-Lucas hypothesis, according to which temporary real effects of purely nominal disturbances result from imperfect information, but departs from the assumptions of Lucas (1973) in two crucial respects. Due to monopolistically competitive pricing, higher-order...

The consequences of information differences across investors in capital markets are still much debated. This paper examines the relation between information differences across investors and the cost of capital, and makes three points. First, in models of perfect competition, information...

In this paper, we examine a supply chain in which a single supplier sells to a downstream newsvendor-type retailer. We make two assumptions that enrich this simple and well-understood model. First, we consider a multi-period model, in which the sequence of events is as follows. In a period, t,...

We study trading behavior and the properties of prices in informationally complex markets. Our model is based on the single-period version of the linear-normal framework of Kyle (1985). We allow for essentially arbitrary correlations among the random variables involved in the model: the value of...

Discussions of financial risk often fail to distinguish between risks that are consciously borne and those that are not. To understand the breeding conditions for financial crises the prime focus of concern should not be simply on large risk-taking per se, but on the unintended, or unanticipated...
