A high-order compact finite difference scheme for a fully nonlinear parabolic differential equation is analyzed. The equation arises in the modeling of option prices in financial markets with transaction costs. It is shown that the finite difference solution converges locally uniformly to the...

The CAPM model assumes stock returns to be a linear function of the market return. However, there is considerable evidence that the beta stability assumption commonly used when estimating the model is invalid. Nonparametric regression methods are used to examine the stability of beta...

This paper analyzes the effect of non-constant elasticity of the pricing kernel on asset return characteristics in a rational expectations model. It is shown that declining elasticity of the pricing kernel can lead to predictability of asset returns and high and persistent volatility. Also,...

Zweck dieses Beitrags ist es, mehrperiodige Modelle für ein Exportunternehmen zu untersuchen, in denen sich eine einfache Export- und Absicherungspolitik als optimal erweist. Eine Politik ist besonders einfach, wenn sie myopisch ist, wenn sie also nur von der Wechselkursverteilung der...

This paper studies the interactions between monetary and fiscal policies in the euro area. The focus is on the union central bank, the German government, and the French government. The policy targets are price stability in the union, full employment in Germany, and full employment in France. The...

Der vorliegende Beitrag untersucht die Wirkungen eines Importzolls auf die Beschäftigung und die Leistungsbilanz der kleinen offenen Wirtschaft. Ne- ben der makroökonomischen Totalanalyse von Zollwirkungen steht die mi- kroökonomische Fundierung des verwendeten Modells im Mittelpunkt. Die...

This paper utilizes the cross-cutting cleavages approach to evaluate the probability of a unanimous constitutional consent and, based on these results, discusses the implications of immigration on an existing constitutional consent. It is shown that previous conclusions of beneficial effects...

This paper analyzes a heterogeneous-agents endogenous-growth model incorporating both transaction costs and social capital. An individual can either become an active part of the society?s middle-class networks of trust and mutual cooperation, thus making a positive contribution to overall social...
