We consider a two-period, one-good financial market, featuring variance-averse investors. Under fairly weak assumptions, like those imposed in the capital asset pricing model, we demonstrate how equilibrium may be approached and computed. As main argument we use the two-dimensionality of pricing...

We consider financial contracts that are tradable in any quantities at fixed prices. A bundle of such contracts constitutes an arbitrage if it offers non-negative payoff in any future state, but commands negative present cost. This article brings together fairly recent results on how to find an...

We use genetic algorithm to learn trading rules for the S&P 500 index using daily prices from 1928 to 1995. After transaction costs, the rules do not earn consistent excess returns over a simple buy-and-hold test periods.

A new model for the analysis of durations, the stochastic conditional dusration (SCD) model is introduced. This model is based on the assumption that the durations are generated by a latent stochastic factor that follows a first order autoregressive process. The lattent factor is perturbed...

This paper develops statistical and computational tools for modelling returns forecasts to be used by a risk neutral investor. Any forecast with the same sign as the conditional mean optimises the loss function derived from this agents' decision problem, so the class of optimal predictors is...

We examine the intertemporal optimal consumption and investment problem in a continuous-time economy with a divisible durable good. Consumption services are assumed to be proportional to the stock of the good held and adjustment of the stock is costly, in that it involves the payment of a...
