The computation of economic equilibria is a centralproblem in algorithmic game theory. In this dissertation, weinvestigate the existence of economic equilibria in severalmarkets and games, the complexity of computing economicequilibria, and its application to rankings.It is well known that a...

Using long-span data on the dollar-sterling and dollar-franc real exchange rates over the past two centuries, we apply the findings of various strands of the recent literature in order to examine the statistical and economic significance of the Harrod-Balassa-Samuelson effect (the effect of...

Within a macroeconomic disequilibrium model it turns out that stationary and simple adaptive policies are not capable of stabilizing efficient steady states and lead to periodic or irregular fluctuations for large sets of policy parameters. The application of recent control methods for chaotic...

Based on a classical financial market model different model variants known from the literature are discussed and analyzed, each focussing on modeling financial markets as a nonlinear dynamic system by introducing the formation of (heterogeneous) beliefs about future asset prices into the model...

This dissertation contains applications of agent-based financial market models and nonlinear econometric methods in financial economics. The first part deals with the analysis of the effectiveness of currency transaction taxes within financial market models with traders with heterogeneous...

The rise of ecosystem management as an approach to renewable resource policy increases the demand for empirical bioeconomics. This paper provides a working definition of bioeconometrics and a taxonomy of model types. A bioeconometric model is a structural model that econometrically estimates one...

In areas from medicine to climate change to economics, we are faced with huge challenges and a need for accurate forecasts, yet our ability to predict the future has been found wanting. The basic problem is that complex systems such as the atmosphere or the economy cannot be reduced to simple...

Extract: As the Heckscher-Ohlin-Mundell paradigm predicts, in a world where capital markets are perfect and production exhibits constant-returns to scale, while aggregate wealth endowments can be an important source of comparative advantage, their internal distribution does not matter for the...

Diese Dissertation beinhaltet drei eigenständige Aufsätze, die die Interaktionen von Bewertungsmodellen für Wertpapiere, Finanzmärkten und der Volkswirtschaft untersuchen. Alle drei Papiere tragen zu einem besseren Verständnis von Verknüpfungen zwischen Finanzmärkten und Realwirtschaft....
