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...

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...

In diesem Papier wird untersucht, welche Auswirkungen die Verfügbarkeit von Infrastruktur auf die unternehmerische Investitionsentscheidung hat. Dabei ist unterstellt, dass Infrastruktur zum einen Input in der Produktionsfunktion ist und zum anderen die Höhe der Anpassungskosten beeinflusst....

In this paper the impacts of income and consumption taxes are analyzed within a model of stochastic endogenous growth with congestion. It is shown that the optimal amount of governmental input diminishes with uncertainty and that the optimal financing depends on the relation between the degrees...

This paper analyzes the impact of pollution and abatement policy within a stochastic endogenous growth model. The agents have environmental preferences, but they neglect their individual contribution to aggregate abatement. Therefore, environmental care is done by the government and financed via...

This paper analyzes stochastic productive pollution within a model of endogenous growth. The extent to which the agents perceive their individual influence on aggregate pollution is parameterized. Recursive preferences allow for the separation between intertemporal substitutability and risk...

This paper investigates the effects of monopolistic competition on entrepreneurial riskRtaking in a general equilibrium model. In this context, occupational choice of risk averse agents is biased towards rm ownership. In this case, the inef ciencies due to the presence of nonRdiversi able risk...

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 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...

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...
