ABSTRACT Portfolio choice by full-scale optimization applies the empirical return distribution to a parameterized utility function, and the maximum is found through numerical optimization. Using a portfolio choice setting of three UK equity indices we identify several utility functions featuring loss aversion and prospect theory, under which full-scale optimization is a substantially better approach than the mean-variance approach. As the equity indices have return distributions with small deviations from normality, the findings indicate much broader usefulness of full-scale optimization than has earlier been shown. The results hold in- and out-of-sample, and the performance improvements are given in terms of utility as well as certainty equivalents. Copyright © 2008 The Authors.

    ABSTRACT: Southern Cone economies exhibit a high record of exchange rate volatility. In this context, rms tend to contract dollar debt, irrespective of their trade orientation, and without available hedging instruments. This exposes them to bankruptcy risk, in the event of large exchange rate movements. This paper provides a framework to analyze the output eect of exchange rate uncertainty in that context, by focusing on the channel uncertainty-output that operates through the nancial strategy of the rm. We nd that increases in exchange rate uncertainty increase the probability of bankruptcy, thus increasing expected marginal bankruptcy costs, and reducing optimal output of a risk-neutral rm. Furthermore, we nd that rms with higher than average liquidity balances will face lower marginal bankruptcy costs, thus producing more than the average rm. The model displays persistence, as any shock to current pro ts aects future liquidity balances, and so, future output. This framework can easily be extended to explain the response of other rms' decisions to exchange rate uncertainty, such as investment.

    ABSTRACT: Full-Scale Optimization (FSO) is a utility maximization approach to portfolio choice problems that has theoretical appeal but that suffers from computational burden in large scale problems. We apply the heuristic technique differential evolution to solve FSO-type asset selection problems of 97 assets under complex utility functions rendering rough utility search surfaces. We show that this problem is computationally feasible and that solutions retrieved with random starting values are converging to one optimum. Furthermore, the study constitutes the first FSO application to stock portfolio optimization. The results indicate that when investors are loss averse, FSO improves stock portfolio performance compared to Mean Variance (MV) portfolios. This finding widens the scope of applicability of FSO, but it is also stressed that out-of-sample success will always be dependent on the forecasting ability of the input return distributions.
