Scientific literature postulates that nanotechnology is to be considered as general purpose technology (GPT), characterized by pervasiveness, high technological dynamism and the inducement of innovations within a variety of applications. We set out to not only further systematize existing...

In recent years demographic aging and its consequences have been recognized and discussed on macroeconomic levels, such as health care system, infrastructure, housing and labour market. However, the consequences are not only present on the macroeconomic level but also affect microeconomic issues...

We conduct an experiment to uncover the reasons behind the typically large behavioral variation and low explanatory power of Nash equilibrium observed in Tullock contests. In our standard contest treatment, only 7% of choices are consistent with Nash equilibrium which is in line with the...

In this paper we study a hedging problem for European options taking into account the presence of transaction costs. In incomplete markets, i.e. markets without classical restriction, there exists a unique martingale measure. Our approach is based on the Föllmer-Schweizer-Sondermann concept of...

The paper develops a dynamical systems approach to study asset bubbles in OLG economies with stochastic production. We derive necessary and sufficient conditions for bubbly equilibria to exist and chracterize the maximum sustainable bubble. Even if they exist, bubbles are temporary and the...

In this article we analyze the interdependent issues of urbanization, growth, and globalization by presenting key empirical facts and relevant underlying economic theories on each. We look more closely, but without providing a detailed formal analysis, at a model by Baldwin and Forslid (2000)...

We introduce a binding unanimous voting rule to a public goods game with an uncertain threshold for the total group contribution. In a laboratory experiment we find that voting generates significantly higher total contributions than making individual voluntary contributions to the public good....

We analyse the potential for shifting freight transports to the railways in Western and Central Europe. This potential arises for large and concentrated freight flows over long distances of about 300 km or more. However, we show that there are only few such freight flows in Europe, and that they...

We apply the well-known CUSUM and the Girshick-Rubin algorithm as trading strategies involving only mutually exclusive long positions in cash and the DAX at Frankfurt mid-day auction prices. We select optimal pairs of fixed thresholds for up- and down-movements from a pre-defined two-dimensional...

This paper investigates the agglomeration of Knowledge Intensive Service (KIS) firms in urban areas. In accordance with the Regional Innovation Systems approach it is argued that cities provide crucial innovation advantages working as centripetal forces for KIS. Applying multivariate logit...
