Taking the First Step - What Determines German Laser Source Manufacturers' Entry into Innovation Networks?

International Journal of Innovation Management,
No. 5,
2015
Abstract
Early access to technological knowledge embodied in the industry’s innovation network can provide an important competitive advantage to firms. While the literature provides much evidence on the positive effects of innovation networks on firms’ performance, not much is known about the determinants of firms’ initial entry into such networks. We analyze firms’ timing and propensity to enter the industry’s innovation network. More precisely, we seek to shed some light on the factors affecting the duration between firm founding and its first cooperation event. In doing so, we apply a unique longitudinal event history dataset based on the full population of German laser source manufacturers. Innovation network data stem from official databases providing detailed information on the organizations involved, subject of joint research and development (R&D) efforts as well as start and end times for all publically funded R&D projects between 1990 and 2010. Estimation results from a non-parametric event history model indicate that micro firms enter the network later than small-sized or large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected findings. The choice of cooperation type makes no significant difference for the firms’ timing to enter the network. Finally, the analysis of geographical determinants shows that cluster membership can, but do not necessarily, affect a firm’s timing to cooperate.

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.

Understanding the Great Recession
Mathias Trabandt, Lawrence J. Christiano, Martin S. Eichenbaum
American Economic Journal: Macroeconomics,
No. 1,
2015
Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

Abstract
Municipality Size, Institutions and Efficiency of Municipal Service Provision: The Case of Saxony-Anhalt In this contribution we analyze the determinants of the efficiency of municipal service provision using the example of the German state of Saxony-Anhalt. The focus lies on the effects of municipality size, institutional setting and spatial or demographic factors. We perform a non-parametric efficiency estimation (Data Envelopment Analysis and the Convex-order-m approach by Daraio and Simar). In contrast to previous studies, we choose the aggregate budget of municipal associations as the object of our analysis since important competences are settled at the joint administrative level. The results show that municipal associations do not necessarily have to be less efficient than independent municipalities. Furthermore, the results for scale efficiency indicate that most municipalities of Saxony-Anhalt had a sufficiently efficient “firm size” in 2004. Moreover, demographic factors and settlement structures have a significant effect on the technical efficiency of towns and municipalities: While a higher population density might be, to some extent, efficiency-enhancing, an increasing share of senior citizens or population growth might have the opposite effect. The integration of spatial interdependencies in efficiency estimations is a complex problem that has only been solved insufficiently yet. However, the estimation results for Moran’s I show mostly statistically significant but, nevertheless, only little or moderate relationships between the single inputs and outputs. Hence, there is no cause for concern about a substantial bias in the results if we neglect spatial interrelationships in our calculation. Furthermore, we found no evidence that the surrounding municipalities benefit from their proximity to core cities by increased efficiency.

The Halle Economic Projection Model

Economic Modelling,
No. 4,
2012
Abstract
In this paper we develop an open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model -- the Halle Economic Projection Model (HEPM) -- is closely related to studies published by Carabenciov et al. Our main contribution is that we model the Euro area countries separately. In doing so, we consider Germany, France, and Italy which represent together about 70 percent of Euro area GDP. The model combines core equations of the New-Keynesian standard DSGE model with empirically useful ad-hoc equations. We estimate this model using Bayesian techniques and evaluate the forecasting properties. Additionally, we provide an impulse response analysis and a historical shock decomposition.

Municipality Size and Efficiency of Local Public Services: Does Size Matter?

IWH Discussion Papers,
No. 18,
2011
published in: FinanzArchiv
Abstract
Similarly to western Germany in the 1960s and 1970s, the eastern part of Germany has experienced a still ongoing process of numerous amalgamations among counties, towns and municipalities since the mid-1990s. The evidence in the economic literature is mixed with regard to the claimed expenditure reductions and efficiency gains from municipal mergers. We therefore analyze the global efficiency of the municipalities in Saxony-Anhalt, for the first time in this context, using a double-bootstrap procedure combining DEA and truncated regression. This allows including environmental variables to control for exogenous determinants of municipal efficiency. Our focus thereby is on institutional and fiscal variables. Moreover, the scale efficiency is estimated to find out whether large units are necessary to benefit from scale economies. In contrast to previous studies, we chose the aggregate budget of municipal associations (“Verwaltungsgemeinschaften”) as the object of our analysis since important competences of the member municipalities are settled on a joint administrative level. Furthermore, we use a data set that has been carefully adjusted for bookkeeping items and transfers within the communal level. On the “eve” of a mayor municipal reform the majority of the municipalities were found to have an approximately scale-efficient size and centralized organizational forms (“Einheitsgemeinden”) showed no efficiency advantage over municipal associations.

Economic Effects of Investment Grants for Water and Sewerage Infrastructure – The Case of Saxony
Peter Haug
Wirtschaft im Wandel,
No. 11,
2010
Abstract
The article deals with the regional economic growth effects of the German “Joint Scheme” for the improvement of regional economic structures (“GA-Infra”). It focuses on water and sewerage projects located in the federal state of Saxony (Germany) during the funding period 2000-2007. Evaluating these projects is important for scientific as well as for economic policy reasons.
First of all, according to general economic theory, the potential direct and indirect supply-side effects of the water and sewerage infrastructure as well as the price effects caused by this infrastructure are relevant for location decisions only to certain branches of the manufacturing industry.
Subsidies for the development of the sewerage infrastructure have been granted mostly according to the growth target of regional policy, i.e. primarily to municipalities with above-average volumes of industry sewage. This finding could not be confirmed for water provision.
A regression analysis (estimating the labour demand of the local manufacturing industry) showed no empirical evidence for any relationship between the changes in labour demand and the amount of GA-Infra funded water and sewerage infrastructure investments. This might be a consequence of the already satisfactory development condition of the infrastructure in question at the beginning of the funding period (“ubiquitous infrastructure”).
According to a survey of local governments conducted by the IWH, these results might be explained by the fact that business customers did not benefit from price reductions despite the GA-Infra funding granted to their local water and sewage disposal providers. Even though there might be some intuitively plausible reasons (decreasing population, no connection fees) for these findings, no effect on firm location decisions can be expected under these circumstances.
All in all, we do not consider the further extension of these funding priorities to be necessary. Especially, the GA-Infra water/sewerage grants should neither be used to mitigate the cost effects of demographic changes or regulation nor to compensate for losses caused by the buyer power of large firms.

Do Banks Benefit from Internationalization? Revisiting the Market Power-Risk Nexus
Claudia M. Buch, C. T. Koch, Michael Koetter
Abstract
Recent developments on international financial markets have called the benefits of
bank globalization into question. Large, internationally active banks have
acquired substantial market power, and international activities have not
necessarily made banks less risky. Yet, surprisingly little is known about the
actual link between bank internationalization, bank risk, and market power.
Analyzing this link is the purpose of this paper. We jointly estimate the
determinants of risk and market power of banks, and we analyze the effects of
changes in terms of the number of foreign countries (the extensive margin) and
the volume of foreign assets (the intensive margin). Our paper has four main
findings. First, there is a strong negative feedback effect between risk and market
power. Second, banks with higher shares of foreign assets, in particular those held
through foreign branches, have higher market power at home. Third, holding
assets in a large number of foreign countries tends to increase bank risk. Fourth,
the impact of internationalization differs across banks from different banking
groups and of different size.
