In this paper we pursue an approach based on economic theory to illustrate possible shortcomings of widely-used detrending methods.We analyze a simple model of economic growth and business cycles in which investment and technical progress are stochastic.The Hodrick-Prescott and the Baxter-King...

This article shows that permanent fluctuations in the cobweb model-though inconsistent with a rational expectations equilibrium-can be justified as being rational when reinterpreting the model in the theory of rational beliefs. Copyright © 2004 John Wiley & Sons, Ltd.

We quantify the effects of financial regulation in an equilibrium model with delegated portfolio management. Fund managers trade stocks and bonds in an order-driven market, subject to transaction taxes and constraints on short-selling and leverage. Results are obtained on the equilibrium...

The problem of dynamic portfolio choice with transaction costs is often addressed by constructing a Markov Chain approximation of the continuous time price processes. Using this approximation, we present an efficient numerical method to determine optimal portfolio strategies under time- and...

This paper proposes a novel approach to the estimation of Customer Lifetime Value (CLV). CLV measures give an indication of the profit-generating potential of customers, and provide a key business tool for the customer management process. The performances of existing approaches are...
