We examine the effects of decreasing down payment requirements on consumption volatility within a model which generalizes the standard buffer-stock model of saving to accommodate durables, nondurables and a collateralized liquidity constraint. We consider both a version of the model without...

Recently, Campbell and Viceira (2002) have introduced a framework that allows for dynamic decisions in asset allocation. This paper follows up their work by showing how uncertainties and expectations may affect consumption and portfolio decisions in an intertemporal dynamic framework. We use the...

Ways of finding a maximum skewness portfolio, with given return, variance and kurtosis, are presented. The methods take advantage of the special shape of the efficient portfolios manifold. Simpler solutions are obtained if the higher moments tensor has some particular structures. The problem of...

In this paper we investigate the performance of the threshold accepting heuristic for the index tracking problem. The index tracking problem consists in minimizing the tracking error between a portfolio and a benchmark. The objective is to replicate the performance of a given index upon the...

We report on progress on a Multistage Stochastic programming model for managing risks in the Danish MBS market. An issuer has the choice between adjustable and fixed rates, both types having various options. An integrated interest-rate and optimization model is needed to manage this complex...

The research on financial engineering by means of genetic programming is gradually popular and appealing. For example, Kaboudan (1999, 2001) and Iba and Sasaki (1999), Iba and Sasaki (1999), used standard GP to evolve forecasting models. Neely, et al. (1997), Allen and Karjalainen (1999), Fyfe...

This paper focuses on the estimation of mutual fund styles by return-based style analysis. Usually, the investment style is assumed to be either constant through time, or time variation is implicitly accounted for by using rolling regressions. The former assumption is often contradicted by data...

A popular argument states that most of the diversification in a portfolio can be obtained with a rather small number of securities. In this paper we present three algorithms to approach the underlying NP-hard problem of portfolio optimization with a cardinality constraint. All three of these...

this problem is sufficiently general to allow (i) risk aversion to vary independently of intertemporal substitution, (ii …) many risky assets, (iii) stochastic labor income that may be correlated with asset returns and/or follow life …-cycle patterns, and (iv) portfolio adjustment costs. We use Weil's (1993) isoelastic/constant absolute risk averse model as a …
