Kann es nach einer Herabstufung der Bonität eines Staates zu einer Dynamik von steigenden Zinsen auf Staatsanleihen und weiter fallenden Ratings kommen, die unausweichlich in einem Staatsbankrott endet? Die hohe Persistenz von Ratings sowie die Beobachtung, dass Zinsen häufig negativ auf eine Herabstufung reagieren, legen die Möglichkeit einer solchen Abwärtsspirale nahe. Empirisch ist diese Dynamik allerdings nicht zu sehen. In den Daten ist im Gegenteil ausschließlich eine sehr langsame Annäherung an ein langfristiges Gleichgewicht von guten Ratings und niedrigen Zinsen zu beobachten. Gleichzeitig ist die Persistenz von Ratings allerdings hoch genug, um nach einer Herabstufung auf ein hochspekulatives Niveau (Rating von B oder schlechter) massive und langandauernde Zinsaufschläge zu erzeugen. Da eine solche Herabstufung in der Realität allerdings äußerst selten erfolgt, ist die Existenz des oben beschriebenen Teufelskreises zu verneinen. Eine negative Entwicklung wie zum Beispiel in Griechenland in den Jahren 2010 und 2011 lässt sich nicht als Ergebnis der Wechselwirkung von Ratings und Zinsen erklären.

The collapse of the communist system has initiated the transformation of Central and Eastern European (CEE) countries from a social-planned towards a market economy. The institutional transition, structural change and privatization process evolved at a different extent across CEE countries. The former satellite states implemented a rapid transformation of the economic system and joined the European Union (EU), whereas the countries of the Commonwealth of Independent States (CIS) faced severe difficulties in adapting their system to the new environment. Due to the lack of capital and knowledge, foreign direct investment (FDI) has played a crucial role in the process of technological renewal and economic development. This thesis consists of two research objectives; the location decision of multinational enterprises (MNE) in CEE regions and the impact of FDI in host economies. This thesis is based on firm level information and takes three theoretical frameworks on FDI into account: International Economics, Regional Economics and International Business. Taking the different transition paths of CEE countries into account, the findings suggest that the regional distribution of FDI differs across sectors and is affected by agglomeration economies and by the access to locally bounded inputs. Therefore, FDI amplifies the concentration of economic activities. The investigation of FDI spillovers provides evidence that FDI contributes to the competitiveness of domestic firms in CEE economies. Notwithstanding, the results show that local firms only benefit from FDI if foreign affiliates are sufficiently embedded in the host economy and global production networks.

This paper provides causal evidence on the impact of succession taxes on firm investment decisions and transfer of control. Using a 2002 policy change in Greece that substantially reduced the tax on intrafamily transfers of businesses, I show that succession taxes lead to a more than 40% decline in investment around family successions, slow sales growth, and a depletion of cash reserves. Furthermore, succession taxes strongly affect the decision to sell or retain the firm within the family. I conclude by discussing implications of my findings for firms in the United States and Europe.

Citizens of the German Democratic Republic (GDR) regained their civil liberties when the Berlin Wall fell 25 years ago. Since then, they have been able to travel freely and have been free to choose where to live and work. The fall of the Berlin Wall was quickly followed by preparations for German Unification at a speed unparalleled in history: the first free Volkskammer elections on 18 March 1990, the economic, monetary and social union on 1 July 1990, and finally, the unification of Germany when the GDR was included in the jurisdiction of the Basic Law of the Federal Republic of Germany. The integration of the economies of East and West Germany, however, has proven to be a drawn-out process.

Following the transition from socialist central planning economies to market economies in all of the former socialist countries, many regions have had to cope with severe structural changes and economic development problems. To overcome these problems, local governments have tried to invest in new public infrastructure to support the development of new industries. This paper looks at infrastructure that supports tourist activities and argues that the impact of infrastructure generally depends on certain local factors which differ between municipalities. One important factor is whether the local population possesses the relevant complementary factors, in particular the right ‘soft skills’.

This inquiry employs ideas advanced by institutionalist thinker Paul Dale Bush to shed light on technology diffusion in Germany’s electrical generation and distribution industry. Research findings suggest that what Bush labeled as ceremonial dominance affects outcomes in technology selection. Evidence suggests that fossil fuel and nuclear technologies have remained favored by power producers despite the externalized environmental costs to society associated with their implementations. Advances in government policy have indeed created a framework that favorably accommodates renewable energy technologies. However, what Bush labeled ceremonial dominance is shown to persist and to contribute to ceremonial encapsulation. Consequently, renewable energy technologies have diffused only to the point that the powers behind the industry remain in dominant positions. Although there is measurable, incremental technological change in the electrical power industry, in light of the urgency of climate change problems, technologies supporting the electrical power system need to be selected more judiciously.

We analyze the impact of financial globalization on volatilities of hours worked and wages of high-skilled and low-skilled workers. Using cross-country, industry-level data for the years 1970–2004, we establish stylized facts that document how volatilities of hours worked and wages of workers with different skill levels have changed over time. We then document that the volatility of hours worked by low-skilled workers has increased the most in response to the increase in financial globalization. We develop a dynamic stochastic general equilibrium model of a small open economy that is consistent with the empirical results. The model predicts that greater financial globalization increases the volatility of hours worked, and this effect is strongest for low-skilled workers.

This paper discusses a tax-transfer scheme that aims to address the under-provision problem associated with the private supply of international public goods and to bring about Pareto optimal allocations internationally. In particular, we consider the example of the global public good ‘climate stabilization’, both in an analytical and a numerical simulation model. The proposed scheme levies Pigouvian taxes globally, while international side-payments are employed in order to provide incentives to individual countries for not taking a free-ride from the international Pigouvian tax scheme. The side-payments, in turn, are financed via environmental taxes. As a distinctive feature, we take into account ancillary benefits that may be associated with local public characteristics of climate policy. We determine the positive impact that ancillary effects may exert on the scope for financing side-payments via environmental taxation. A particular attractive feature of ancillary benefits is that they arise shortly after the implementation of climate policies and therefore yield an almost immediate payback of investments in abatement efforts. Especially in times of high public debt levels, long periods of amortization would tend to reduce political support for investments in climate policy.

Monetary policy can have an impact on economic and financial stability through the risk taking of banks. Falling interest rates might induce investment into risky activities. This paper provides evidence on the link between monetary policy and bank risk taking. We use a factor-augmented vector autoregressive model (FAVAR) for the US for the period 1997–2008. Besides standard macroeconomic indicators, we include factors summarizing information provided in the Federal Reserve’s Survey of Terms of Business Lending (STBL). These data provide information on banks׳ new loans as well as interest rates for different loan risk categories and different banking groups. We identify a risk-taking channel of monetary policy by distinguishing responses to monetary policy shocks across different types of banks and different loan risk categories. Following an expansionary monetary policy shock, small domestic banks increase their exposure to risk. Large domestic banks do not change their risk exposure. Foreign banks take on more risk only in the mid-2000s, when interest rates were ‘too low for too long’.

Our primary goal is to analyse the drivers of evolutionary network change processes by using a stochastic actor-based simulation approach. We contribute to the literature by combining two unique datasets, concerning the German laser and automotive industry, between 2002 and 2006 to explore whether geographical, network-related, and techno-logical determinants affect the evolution of networks, and if so, as to what extent these determinants systematically differ for science-driven industries compared to scale-intensive industries. Our results provide empirical evidence for the explanatory power of network-related determinants in both industries. The ‘experience effect’ as well as the ‘transitivity effects’ are significant for both industries but more pronounced for laser manufacturing firms. When it comes to ‘geographical effects’ and ‘technological ef-fects’ the picture changes considerably. While geographical proximity plays an important role in the automotive industry, firms in the laser industry seem to be less dependent on geographical closeness to cooperation partners; instead they rather search out for cooperation opportunities in distance. This might reflect the strong dependence of firms in science-driven industries to access diverse external knowledge, which cannot necessarily be found in the close geographical surrounding. Technological proximity negatively influences cooperation decisions for laser source manufacturers, yet has no impact for automotive firms. In other words, technological heterogeneity seems to ex-plain, at least in science-driven industries, the attractiveness of potential cooperation partners.
