Calibrated models of the business cycle typically assume a certain frequency at which economic agents take decisions. In this paper I show that the local stability properties of dynamic stochastic general equilibrium macro models may depend on the length of a period in the model economy. This...

This paper analyses the robustness of Least-Squares Monte Carlo, a technique recently proposed by Longstaff and Schwartz (2001) for pricing American options. This method is based on least-squares regressions in which the explanatory variables are certain polynomial functions. We analyze the...

The growth of unsolicited commercial email imposes increasing costs on organizations and causes considerable aggravation on the part of email recipients. A thriving anti-spam industry addresses some of the frustration. Regulation and various economic and technical means are in the works –...

Cosimano (2003) uses the perturbation method to approximate optimal experimentation problems in the neighborhood of the augmented linear regulator problem as formulated by Hansen and Sargent (2004) and Anderson, Hansen, McGratten and Sargent (1966). Cosimano and Gapen (2005) develop a computer...

We examine several named subsets of the wealthiest individuals in the US and the UK that are compiled by Forbes Magazine and Sunday Times.
