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...

In this thesis it is analyzed if promoting product market competition can help to to fight unemployment in Europe. We have used a general equilibrium model in order to study how reducing mark-ups and increasing productivity in one sector affect aggregate unemployment for an exogenously given...

The present thesis consists of seven papers specifying and analysing models of direct-interactions-driven collective economic phenomena. Within theories and models of coordination in large decentralized market economies (and analogously also within theories and models of coordination in natural...

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...

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...

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...

Diese Arbeit beschäftigt sich mit der Integration unfreiwilliger Arbeitslosigkeit in allgemeine Gleichgewichtsmodelle offener Volkswirtschaften. Das Walras oder Arrow-Debreu allgemeine Gleichgewichtskonzept wird im Licht unfreiwilliger Arbeitslosigkeit neu bewertet, und mit dem allgemeinen...

We consider misconceptions about the functioning of the economy as one possible explanation for the emergence of crises in democracies. Furthermore, we study a political process which may lead to successful reform. First of all, we show that voters can make inefficient decisions concerning...

General financial models have become workhorse models in the fields of macroeconomics and finance. These models have been developed and extensively studied by general equilibrium theorists. What makes them so applicable for macroeconomics and finance is the well accepted fact that models with a...
