We study the correlation of monthly excess returns for seven major countries over the period 1960-1990. We find that the international covariance and correlation matrices are unstable over time. A multivariate GARCH(1,1) modelling with constant conditional correlation helps capture some of the...

An informed agent - whose welfare depends on two state variables, s1 and s2 - chooses a linear signalling rule that translates his private signal into a public signal. Conditional on the public signal receivers, whose welfare depends on state 1 alone, take actions which affect the informed...

If a stochastically monotone function of asymmetrically informed individuals' expectations of a random vector is common knowledge, than all the individuals must agree on their expectations. This result generalizes the theorem of Nielsen, Brandenburger, Geanakoplos, McKelvey and Page (1989) from...

In this paper we present a two-factor model, which values American crude oil futures options using the spot price and the net marginal convenience yield of crude as the relevant state variable. The model also accounts for a non-stationary market price of convenience yield risk, the value of...

This paper investigates the performance of mutual funds in Spain between January and June 1990. The robustness of results to alternative measurements and benchmarks is carefully analysed. As expected, the results indicate that, with monthly returns, it is not possible to measure the magnitudes...

The change in the market mechanism on the Helsinki Stock Exchange was examined in order to study the impact of order book visibility and continuity on the liquidity distribution. The hypothesis was that the change in continuity and order book visibility resulted in a shift in liquidity from...

The aim of this paper is to characterize the empirical implications for dynamic investment models of the hierarchy of finance model of corporate finance and to test these implications using firm level data. The model we estimate is based on the Euler equation for optimal capital accumulation in...

Dealers are suppliers of liquidity; in this respect their role is similar to that played by speculators in auction markets. However, dealers are a special kind of speculator, because of the many obligations and privileges conferred upon them. The most obvious constraint on dealers' behaviour is...

In this paper we explore how a cartel which is able to cooperate to a limited degree on a futures market may be able to implement a cooperative production plan which would be self-enforcing. The basic result of the paper is that appropriately chosen initial allocations of long positions in the...

Suppose that information about the value of a risky asset is dispersed among many agents in the economy. The paper studies the rate at which successive price quotations from competitive market makers, which reflect the desired (notional) trades of risk- averse informed agents, reveal the value...
