This paper is aimed in analyzing the impact of the growing use of contingent claims in the objectives of monetary policy. To reach this end, a continuous time, stochastic model of macroeconomic equilibrium of a monetary economy where the agents are exposed to the risk market is developed. In the...

This paper investigates the price for contingent claims in a dual expected utility theory framework, the dual price, considering complete arbitrage-free nancial markets. In this framework this dual price is obtained, for the rst time in the literature, without any comonotonicity hypothesis and...

In this paper, we study securities market models with fixed costs. We characterize the absence of arbitrage opportunities and we provide fair pricing rules. We then apply these results to extend some popular interest rate and option pricing models, which present arbitrage opportunities in the...

This paper studies foundational issues in securities markets models with fixed costs of trading, i.e. transactions costs that are bounded regardless of the transaction size, such as fixed brokerage fees, investment taxes, operational, and processing costs or opportunity costs. We show that the...

We examine the behavior of forward and spot exchange rates from the perspective of the representative agent theory of asset pricing. We verify that with moderate risk aversion and time-additive preferences the theory accounts for very little (by our calculations, less than 5 percent) of the...
