We present in this paper a particular Metropolis-type algorithm for the simulation of a beta (formula) variable whose convergence is extremely slow. The interest of this phenomenon is to provide a simple benchmark against which convergence control techniques can be tested. We illustrate this use...

Drawing upon recent contributions in the statistical literature, we present a new result on the convergence of recursive, stochastic algorithms which can be applied to economic models with learning. The formal result provides probability bounds for convergence which can be used to describe the...

Two terms of a second-order approximation to the bias of the multivariate OLS estimate are derived using the same technique as in Nicholls and Pope (1988). The resulting second-order bias approximation is then tested against first-order alternatives on two bivariate Monte Carlo simulated VAR...

Portfoliomanager werden stets mit Selektions- und Timingentscheidungen konfrontiert, die den Erfolg einer Anlage am Aktienmarkt maßgeblich bestimmen. Ignazio Benenati untersucht, wie sich künstliche neuronale Netze im Portfoliomanagement zur Lösung des Selektions- und Timingproblems einsetzen...

Besides scheduling problems for single and parallel machines and shop scheduling problems the book covers advanced models involving due-dates, sequence dependent changeover times and batching. Also multiprocessor task scheduling and problems with multipurpose machines are discussed. The methods...
