This paper analyzes the choice of taxes and international information exchange by governments in a capital tax competition model. We explain situations where countries can choose tax rates on tax savings income and exchange information about the domestic savings of foreigners, implying that the...

This paper examines information sharing between governments in an optimaltaxation framework. We present a taxonomy of alternative systems of international capital-income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the...

In diesem Beitrag wird untersucht, welchen Einfluss die Entlohnung eines Managers mit Fixum und gewinnbezogenem Bonus auf seinen Arbeitseinsatz und seine Bilanzpolitik ausübt. Dazu wird das LEN-Modell auf die gesamte Lebensdauer des Unternehmens erweitert. Die Gewinnmanipulationen müssen sich...

In a simple portfolio choice model of two assets a foreign exchange transactions tax is implemented. We show that the graph in the mu-sigma[square] range is still a parabola and delineate its characteristics for altering tax rates. We presumed a risk avers investor seeking to minimize investment...

We consider a quasilinear parabolic equation with quadratic gradient terms. It arises in the modelling of an optimal portfolio which maximizes the expected utility from terminal wealth in incomplete markets consisting of risky assets and non-tradable state variables. The existence of solutions...

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...
