The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
In the present paper, we build a bivariate semiparametric dynamic panel model to repro-duce the joint dynamics of sovereign ratings and government bond yields. While the individual equations resemble Pesaran-type cointegration models, we allow for different long-run relationships in both equations, nonlinearities in the level effect of ratings, and asymmetric effects in changes of ratings and yields. We find that the interest rate equation and the rating equation imply significantly different long-run relationships. While the high persistence in both interest rates and ratings might lead to the misconception that they follow a unit root process, the joint analysis reveals that they converge slowly to a joint equilibrium. While this indicates that there is no vicious cycle driving countries into default, the persistence of ratings is high enough that a rating shock can have substantial costs. Generally, the interest rate adjusts rather quickly to the risk premium that is in line with the rating. For most ratings, this risk premium is only marginal. However, it becomes substantial when ratings are downgraded to highly speculative (a rating of B) or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

Isolation and Innovation – Two Contradictory Concepts? Explorative Findings from the German Laser Industry
Wilfried Ehrenfeld, T. Pusch, Muhamed Kudic
IWH Discussion Papers,
No. 1,
2015
Abstract
We apply a network perspective and study the emergence of core-periphery (CP) structures in innovation networks to shed some light on the relationship between isolation and innovation. It has been frequently argued that a firm’s location in a densely interconnected network area improves its ability to access information and absorb technological knowledge. This, in turn, enables a firm to generate new products and services at a higher rate compared to less integrated competitors. However, the importance of peripheral positions for innovation processes is still a widely neglected issue in literature. Isolation may provide unique conditions that induce innovations which otherwise may never have been invented. Such innovations have the potential to lay the ground for a firm’s pathway towards the network core, where the industry’s established technological knowledge is assumed to be located.
The aim of our paper is twofold. Firstly, we propose a new CP indicator and apply it to analyze the emergence of CP patterns in the German laser industry. We employ publicly funded Research and Development (R&D) cooperation project data over a period of more than two decades. Secondly, we explore the paths on which firms move from isolated positions towards the core (and vice versa). Our exploratory results open up a number of new research questions at the intersection between geography, economics and network research.

Municipal Size, Administrative Structure and Election Turnout: Consequences of Municipal Reform for the Legitimisation of Political Decision-making Processes

Gebiets- und Verwaltungsstrukturen im Umbruch: Beiträge zur Reformdiskussion aus Erfahrungen in Sachsen, Sachsen-Anhalt und Thüringen,

Abstract
In the political debate voices are repeatedly heard calling for municipal territories to be enlarged and to dispense with internal administrative sub-divisions of the municipal entities, hence realising the model of the so-called unitary municipality and not that of the federally conceived municipalities. The “costs“ in terms of the economic disadvantages of this centralised model are usually only mentioned in passing, not least due to the problems of quantifying these costs. This paper attempts such a quantification for one aspect of the economic disadvantages of larger and more centralised municipal entities, namely their negative effects on election turnouts. The results of the empirical investigations show that the theoretical suppositions are confirmed, demonstrating that (1.) the choice of the organisational form of municipal administrative entity affects turnout, and (2.) the unitary municipality form leads to a significantly lower election turnout than that found in federally organised types of municipality.

Spatial Development in View of the Re-structuring of Public Administrations – What are the Implications of the Individual Contributions?

Gebiets- und Verwaltungsstrukturen im Umbruch: Beiträge zur Reformdiskussion aus Erfahrungen in Sachsen, Sachsen-Anhalt und Thüringen,
No. 360,
2015
Abstract
It must be clear that any kind of appraisal drawn from the results of the individual papers can only be an interim one. Many of the issues raised in the pertinent field of investigation could only be touched upon without being sufficiently debated. In other cases the results of the papers show that further and more thorough investigations are urgently required. It may be stated that public administration structures are basically in a state of constant change, and must repeatedly be adapted to changing economic and social framework conditions. In terms of legal boundaries to territorial restructuring, it should be noted that the size of a municipality may not be permitted to obstruct either the political participation of citizens or the possibility of the municipal decision-makers being sufficiently well-informed.
The overall picture furthermore suggests that reforms in the public sector sphere that are initiated by state actors (i.e. top down) are always extremely complicated affairs.
The objective of the regional working group of the Academy of Spatial Research and Planning (ARL) for the states Sachsen, Sachsen-Anhalt and Thüringen was to highlight some of the most significant aspects of the process of municipal re-structuring and its effects on spatial development, considering these in the three states against the background of current discussions and reform measures.

Drivers of the Spatial Emergence and Clustering of the Photovoltaic Industry in Germany

Zeitschrift für Wirtschaftsgeographie,
No. 3,
2015
Abstract
The drivers of the spatial emergence and clustering of the photovoltaic industry in Germany. Following the relatedness literature, we explore to what extent related industries influenced the regional emergence of the photovoltaic (PV) industry. In addition, we shed light on factors explaining selective processes of clustering. We particularly argue that generic resources and resources of related activities have been crucial for the regional concentration in early phases of the industry life cycle. With increasing maturity, industry-specific resources became more important. Based on a unique dataset containing population dynamics of the German PV industry, the hypotheses are tested empirically. Our results partially confirm the assumed beneficial effects of related industries for the emergence of the PV industry. Moreover, we observe changes in the relative importance of factors supporting regional concentration, with industry-specific resources becoming dominant as the industry matures.

25 Years after the Fall of the Berlin Wall: The Economic Integration of East Germany
One-off Publications,
2014
Abstract
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.

The Role of Entrepreneurship in US Job Creation and Economic Dynamism
Ryan A. Decker, John Haltiwanger, Ron S. Jarmin, Javier Miranda
Journal of Economic Perspectives,
No. 3,
2014
Abstract
An optimal pace of business dynamics—encompassing the processes of entry, exit, expansion, and contraction—would balance the benefits of productivity and economic growth against the costs to firms and workers associated with reallocation of productive resources. It is difficult to prescribe what the optimal pace should be, but evidence accumulating from multiple datasets and methodologies suggests that the rate of business startups and the pace of employment dynamism in the US economy has fallen over recent decades and that this downward trend accelerated after 2000. A critical factor in accounting for the decline in business dynamics is a lower rate of business startups and the related decreasing role of dynamic young businesses in the economy. For example, the share of US employment accounted for by young firms has declined by almost 30 percent over the last 30 years. These trends suggest that incentives for entrepreneurs to start new firms in the United States have diminished over time. We do not identify all the factors underlying these trends in this paper but offer some clues based on the empirical patterns for specific sectors and geographic regions.

Musterknabe Osteuropa: Subventionskontrolle und staatliche Beihilfen
Jens Hölscher
Wirtschaftsdienst,
No. 5,
2014
Abstract
Ten years after the biggest enlargement in the history of the EU, the integration of the new member states is assessed positively. It is considered an economic success when looking at the income levels. However, due to overly optimistic assumptions and the crisis, economic integration and the catching-up process will take much longer for the new EU member states than originally expected. Moreover, new challenges are looming, especially as the Central and Eastern European accession countries adopt the euro. Smaller countries introduced the euro as quickly as possible, whereas larger countries have been much more hesitant, thinking twice not only because of several unsolved problems in the euro area but also because they use the exchange rate tool much more intensively. All new member states have to make sure they continue to increase their productivity and competitiveness. Findings suggest that after having entered the EU, the new eastern member states appear to have been developing rather stringent competition cultures. Bulgaria and Romania’s transition performance significantly differs from the pattern in the 2004 accession countries, both in terms of quantitative growth and institutional quality. These countries show that EU funds can be highly counter-productive since they help to conserve old structures.

The Skills Balance in Germany’s Import Intensity of Exports: An Input-Output Analysis
Udo Ludwig, Hans-Ulrich Brautzsch
Intereconomics,
No. 2,
2014
Abstract
In the decade prior to the economic and financial crisis, Germany’s net exports increased in absolute terms as well as relative to the growing level of import intensity of domestically produced export goods and services. This article analyses the direct and indirect employment effects induced both by exports as well as by of the import intensity of the production process of export goods and services on the skills used. It shows that Germany’s export surpluses led to positive net employment effects. Although the volume of imports of intermediate goods increased and was augmented by the rise in exports, it could not undermine the overall positive employment effect.
