Abstract
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.

The Ex Ante versus Ex Post Effect of Public Guarantees

Abstract
In October 2006, Dominion Bond Rating Service (DBRS) introduced new ratings for banks that account for the potential of government support. The rating changes are not a reflection of any changes in the respective banks’ credit fundamentals. We use this natural experiment to evaluate the consequences of bail out expectations for bank behavior using a difference in differences approach. The results suggest a striking difference between the effects of bail out probabilities during calm times (“ex ante”) versus during crisis times (“ex post”). During calm times, higher bail-out probabilities result in higher risk taking, consistent with the moral hazard view and much of the empirical literature. However, in crisis times, we find that banks with higher bail out probabilities tend to increase their risk taking less compared to banks that were ex ante unlikely to be bailed-out. Charter values are one part of the explanation: Supported banks may have a funding advantage relative to non-supported banks during the crisis. However, we cannot rule out that other factors also may be playing a role, including tighter supervision of supported banks in crisis times.

Subsidized Vocational Training: Stepping Stone or Trap? – Assessing Empirical Effects using Matching Techniques
Eva Dettmann, Jutta Günther
Swiss Journal of Economics and Statistics,
No. 4,
2013
Abstract
Using replacement matching on the basis of a statistical distance function we try to answer the question of whether subsidized vocational training is related to a negative image effect for the graduates. The results show that young people with equal qualifications acquired during subsidized vocational training are disadvantaged solely due to the kind of education they have received. The probability of finding adequate employment is lower than in the control group. Besides the 'general effect' of support we also find less favorable job opportunities for those who attended 'external' as compared to 'workplace-related' training.

Evaluation of the Main Achievements of Cohesion Policy Programmes over the Longer Term in 15 Selected Regions (from 1989-1993 Programming Period to the Present) (2011.CE.16.B.AT.015): Case Study Sachsen-Anhalt

Analyse: Bewertungen des Programmplanungszeitraums,

Abstract
Sachsen-Anhalt’s regional development has been heavily determined by the transition from a centrally planned economy to a market economy after German unification in 1990. The process of transition took place during the 1990s as the formal rules associated with a market economy system were adopted. Nevertheless, a number of structural peculiarities which have their roots in the transition period continue to have an impact. This feature is not specific to Sachsen-Anhalt; it concerns all East German regions.

Skill Content of Intra-european Trade Flows
Götz Zeddies
European Journal of Comparative Economics,
No. 1,
2013
Abstract
In recent decades, the international division of labor has expanded rapidly in the wake of European integration. In this context, especially Western European high-wage countries should have specialized on (human-)capital intensively manufactured goods and should have increasingly sourced labor-intensively manufactured goods, especially parts and components, from Eastern European low wage countries. Since this should be beneficial for the high-skilled and harmful to the lower-qualified workforce in high-wage countries, the opening up of Eastern Europe is often considered as a vital reason for increasing unemployment of the lower-qualified in Western Europe. This paper addresses this issue by analyzing the skill content of Western European countries’ bilateral trade using input-output techniques in order to evaluate possible effects of international trade on labor demand. Thereby, differences in factor inputs and production technologies have been considered, allowing for vertical product differentiation. In this case, skill content of bilateral exports and imports partially differs substantially, especially in bilateral trade between Western and Eastern European countries. According to the results, East-West trade should be harmful particularly to the medium-skilled in Western European countries.

Bottom-up or Direct? Forecasting German GDP in a Data-rich Environment
Katja Drechsel, Rolf Scheufele
Abstract
This paper presents a method to conduct early estimates of GDP growth in Germany. We employ MIDAS regressions to circumvent the mixed frequency problem and use pooling techniques to summarize efficiently the information content of the various indicators. More specifically, we investigate whether it is better to disaggregate GDP (either via total value added of each sector or by the expenditure side) or whether a direct approach is more appropriate when it comes to forecasting GDP growth. Our approach combines a large set of monthly and quarterly coincident and leading indicators and takes into account the respective publication delay. In a simulated out-of-sample experiment we evaluate the different modelling strategies conditional on the given state of information and depending on the model averaging technique. The proposed approach is computationally simple and can be easily implemented as a nowcasting tool. Finally, this method also allows retracing the driving forces of the forecast and hence enables the interpretability of the forecast outcome.

Presses Académiques Francophones, Saarbrücken,
2013
Abstract
Grundlage der Untersuchung ist die Annahme, dass das Entwicklungspotential einer Industrie bzw. einer Region von ihrer Innovationstätigkeit abhängt. Im Speziellen werden Antworten auf folgende Fragestellungen gesucht: Lässt sich das Cluster-Konzept auf die maritime Industrie der maritimen Region Québecs übertragen? Kann dieser Sektor eine solch große Bedeutung und Wirtschaftskraft erlangen, dass er zu einem wirtschaftlichen Standbein dieser Region werden kann? Der Untersuchung liegen die Umfrageergebnisse einer regionalen Studie zugrunde, die insbesondere die Unternehmenseigenschaften, wie beispielsweise, Größe, Umsatz oder Anzahl der im Unternehmen tätigen Ingenieure, erfasste. Die Ergebnisse zeigen, dass der Großteil der Unternehmen in der untersuchten Stichprobe kleine und mittelständische Unternehmen sind, die nur wenig Innovationsaktivitäten haben. Insgesamt deuten die Ergebnisse darauf hin, dass der untersuchte maritime Sektor nicht die geeigneten Eigenschaften aufweist um dort das Konzept eines Clusters als Regionalentwicklungsstrategie anwenden zu können.

How to Create a New Holiday Destination? An Evaluation of Local Public Investment for Supporting Tourism Industry
Albrecht Kauffmann, Martin T. W. Rosenfeld
Quantitative Methods in Tourism Economics,
2013
Abstract
Since the 1990s tourism has been one major area in Saxony where new local public infrastructure has been created. The question is whether this newly-built tourism infrastructure has been able to change the path of economic development in those municipalities where the investment has occurred. Is it possible to activate the tourism industry with the help of public investment at locations that are completely new to the tourism industry? The econometric estimations and a survey of businesses in the field of tourism make it clear that the new tourist infrastructure really did have a positive effect on local employment – but not everywhere and not in every case. Tourist infrastructure will only have a major positive impact on economic development if a municipality already has a “track record” of being a tourist destination and is well-equipped with the relevant complementary factors for tourist activities and the “primary features” of tourist destinations – History matters!

Qual VAR Revisited: Good Forecast, Bad Story
Makram El-Shagi, Gregor von Schweinitz
Abstract
Due to the recent financial crisis, the interest in econometric models that allow to incorporate binary variables (such as the occurrence of a crisis) experienced a huge surge. This paper evaluates the performance of the Qual VAR, i.e. a VAR model including a latent variable that governs the behavior of an observable binary variable. While we find that the Qual VAR performs reasonably well in forecasting (outperforming a probit benchmark), there are substantial identification problems. Therefore, when the economic interpretation of the dynamic behavior of the latent variable and the chain of causality matter, the Qual VAR is inadvisable.
