Noting that many economic variables display occasional shifts in their second order moments, we investigate the performance of homogenous panel unit root tests in the presence of permanent volatility shifts. It is shown that in this case, panel unit root tests derived under time invariant...

Die Arbeit beschäftigt sich mit der Investition in neue, emissionsärmere Technologien, bei dem der Entscheider eine große, langfristige Investition tätigt und den dafür optimalen Zeitpunkt wählt. Dabei wird sowohl der gesamtwirtschaftliche Kontext, also die effiziente Allokation der neuen...

Intertemporal general-equilibrium models with Keynesian features such as imperfect competition and imperfectly flexible prices which give rise to a (at least) short-run non-neutrality of monetary policy have become the workhorse model for monetary macroeconomics. This thesis now makes four...

In this dissertation, I present five dynamic general equilibrium models. The distinguishing feature of these models is that they incorporate reciprocal altruistic behavior into an otherwise standard New Keynesian framework. In particular, I extend the New Keynesian model such that the assumed...

This doctoral thesis investigates the influence of overconfidence on the outcomes in experimental asset markets, both on the market and individual levels. Thesis consists of three parts. In the first part an instrument (test) is developed that is later used in economic experiments to measure...

Since the 1990s, the effective global labor supply has increased strongly, in particular due to the integration of China and India into the global markets. This rise has also deteriorated the situation of low-skilled workers in advanced economies. This development raises important challenges for...

This thesis is a collection of research papers examining global economic integration, technology diffusion and climate change and their interactions and policy implications. Chapter 1 theoretically analyzes the effect of changes in regional production costs on the inter-regional allocation of...

This dissertation examines the key prediction of trade models à la Dixit-Stiglitz for the EU-27. Precisely, we test if regional market accessibility determines regional income differences in the enlarged European Union. We propose an empirical strategy that overcomes weaknesses of existing...

The purpose of this doctoral thesis is to suggest and operationalise several important extensions and improvements in the methodology used to evaluate regional economic effects of the large-scale transport infrastructure and pricing policies. The main contributions are divided into the static...
