Das Papier untersucht, wie Erwartungsbildung mit Hilfe neuronaler Netze modelliert werden kann. Die Grundlage bildet ein Cobweb-Modell, in dem Firmen Preiserwartungen auf Basis eines Feedforward-Netzes bilden.Zunächst wird anhand von Simulationen gezeigt, daß Firmen durch neuronale...

This paper analyzes the relationship between the expectational stability of rational expectations equilibria and the possible convergence of adaptive learning processes. Results obtained using recursive least squares lead to the conjecture that a correspondence between these both selection...

We discuss long-run growth in an economy which is subject to aggregate productivity shocks affecting all factors of production. We demonstrate that the presence of labor income risk unambiguously is an important determinant of long-run expected growth. The issue of dynamic inefficiency of the...

This paper discusses a two-sector neoclassical overlapping generations economy with intermediate and final goods in the spirit of Romer (1990). The risk averse agents engage in one of two alternative occu pations: either firrm-ownership in the intermediate goods sector, char acterized by...

This paper explores the question whether boundedly rational agents learn to behave optimally when asked to voluntarily contribute to a public good. The decision process of individuals is described by an Evolutionary Algorithm. We analyze the learning process of purely and impurely altruistic...

This paper analyzes growth and welfare effects of income taxation in a stochastic endogenous growth model with externalities in human-capital accumulation. The government participates in individual income risks by the collection of a flat-rate income tax that affects the mean and the variance of...

This paper is concerned with occupational choice under risk, where agents care about their social status. It is motivated by recent developments in the 'New Economy', which indicate that status preferences possibly provide an explanation for the observed shift towards entrepreneurial...
