This paper introduces a new theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets. We analyze a simple security design model which endogenizes not only the characteristics of each individual...

A speculative security is an asset whose payoff depends on a random shock uncorrelated with economic fundamentals (a sunspot) about which some traders have superior information. In this paper we show that agents may find it desirable to trade such a security in spite of the fact that it is a...

A speculative security is an asset whose payoff depends in part on a random shock uncorrelated with economic fundamentals (a sunspot) about which some traders have superior information. In this paper we show that agents may find it desirable to trade such a security in spite of the fact that it...

This paper describes the experimental studies carried out to test thermal cycling of a real-scale PCM–air heat exchanger at ambient temperatures. To achieve this goal an experimental setup previously designed and used for testing real-scale prototypes of PCM–air heat exchangers is modified....

In this paper we study the drawdown status of hedge funds as a hedge fund characteristic related to performance. A hedge fund's drawdown status is the decile to which the fund belongs in the industry's drawdown distribution (at a given point in time). Economic reasoning suggests that both the...

This paper documents that at the individual stock level, insiders' sales peak many months before a large drop in the stock price, while insiders' purchases peak only the month before a large jump. We provide a theoretical explanation for this phenomenon based on trading constraints and...

Fund managers are double agents; they serve both fund investors and owners of management firms. This conflict of interest may result in trading to support securities prices. Tests of this hypothesis in the Spanish mutual fund industry indicate that bank-affiliated mutual funds systematically...

In this article we show that in the presence of trading constraints, such as short sale constraints, the standard definition of a Rational Expectations Equilibrium allows for equilibrium prices that reveal information unknown to any active trader in the market. We propose a new definition of the...
