We solve in closed form the optimal consumption / portfolio choice problem for the class of isoelastic utility functions under incomplete information about the mean return of the stock price. Our approach consists in converting the original investor's problem into an equivalent program where the...

This paper investigates the uncertainty in variance and covariance of asset returns. It is commonly believed that these second moments can be estimated very accurately. However, time varying volatility and nonnormality of asset returns can lead to imprecise variance estimates. Using CRSP value...

I develop a Markov model of samrt money chasing past winning funds while taking into account associated costs. The model also allows market capital entry and exit. The steady-state capital allocations re derived using constant transition probabilities. The results sugget that down side risk is...

Se estudia asignaciones óptimas de clases de activo (Asset Allocation) para afiliados representativos a las AFP con diferentes plazos para jubilar. Se supone que el afiliado desearía maximizar su pensión esperada al momento de jubilar, dado un nivel de riesgo. Entonces, la pregunta es qué...

We examine the equity market price interdependence between Australia, on one hand, and Japan, US, UK, Hong Kong, Singapore, Taiwan and Korea, on the other hand, based on Hacker and Hatemi-J (2003) bootstrap causality tests with leveraged adjustments. We cover the period January 1, 1993 to...

Surveys of Australian superannuation funds verify that most international bond holdings, but not equity holdings, are hedged for currency risk. We compare the mean-variance efficiency of this practice with two alternative strategies: a conventional forward hedge; and a selective hedge triggered...

This paper supplements Dark (2003c) where bivariate error correction GARCH and FIGARCH models between the All Ordinaries Index and its Share Price Index (SPI) futures are used to estimate dynamic minimum variance hedge ratios (MVHRs). Dark (2003c) documents the importance of allowing for long...

A new explanation for the well-known reluctance of retirees to buy life annuities is due to Milevsky and Young (2002, 2003). Specifically, the decision to buy longevity insurance is largely irreversible, so that the real option to delay annuitization generally has value. Milevsky and Young...

The structure of many models in economics and finance depends on majorization properties of convolutions of distributions. In this paper, we analyze robustness of these properties and the models based on them to heavy-tailedness assumptions. We show, in particular, that majorization properties...

The paper explores the implications of means of payment substitutability and capital mobility on the properties of the money demand, using the Thomas (1985) stochastic dynamic optimising model, where the specific role of money is explicitly accounted for. Extending the model to a case in which...
