This paper investigates the effects of monopolistic competition on entrepreneurial risk-taking in a general equilibrium model. In this context, occupational choice of risk averse agents is biased towards firm ownership. In this case, the inefficiencies due to the presence of non-diversifiable...

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 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...

This paper employs a stochastic endogenous growth model with productive government expenditure to analyze the macroeconomic effects of income taxation. We demonstrate that in the presence of capital and income risk the impact of taxation on consumption choice as well as on economic growth is...

Dieser Beitrag gibt einen Überblick über Ansatzpunkte und Möglichkeiten zur Integration von Lernprozessen in volkswirtschaftliche Fragestellungen. Es werden alternative Methoden vorgestellt, individuelle aber auch gesellschaftliche Lernenvorgänge in ökonomischen Modellen zu erfassen.

Der vorliegende Beitrag analysiert den Einfluß von aggregierten Produktivitätsschocks auf die intertemporale Entscheidung risikoaverser Agenten. Dabei stehen insbesondere die Auswirkungen auf das langfristige Wachstum der Ökonomie im Vordergrund der Betrachtungen. Es wird gezeigt, daß neben...

Dieser Beitrag bietet eine Einführung in eine Gruppe moderner Algorithmen, den sogenannten evolutionären Optimierungsverfahren. Anhand eines einfachen Beispiels wird die grundsätzliche Funktionsweise dieser Algorithmen skizziert. Darüberhinaus wird ein Überblick über die...

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 examines the learning dynamics of boundedly rational agents, who are asked to voluntarily contribute to a discrete public good. In an incomplete information setting, we discuss contribution games and subscription games, the latter including a money-back guarantee in case of provision...
