Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model
Marco Sunder
IWH Discussion Papers,
No. 22,
2009
Abstract
We analyze the timing of birth of the first three children based on German panel
data (GSOEP) within a hazard rate framework. A random effects estimator is
used to accommodate correlation across spells. We consider the role of human
capital – approximated by a Mincer-type regression – and its gender-specific
effects on postponement of parenthood and possible recuperation at higherorder
births. An advantage of the use of panel data in this context consists in
its prospective nature, so that determinants of fertility can be measured when
at risk rather than ex-post, thus helping to reduce the risk of reverse causality.
The analysis finds evidence for strong recuperation effects, i.e., women with
greater human capital endowments follow, on average, a different birth history
trajectory, but with negligible curtailment of completed fertility.

Deutsche Einheit – ein wirtschaftlicher Gewinn
Ulrich Blum
MUT – Zeitschrift für Kultur,
2009
Abstract
20 years after the fall of the wall the interest in the evaluation of the economic development of Germany after unification has increased. The article shows that from a Western German perspective, unification generated large gains because in an expending fail of economic development highly qualified personal from East Germany could be attracted and triggered growth in the West. This also generated a modernization of industry. The perspective on the Eastern side is more mixed. After a first transitory face, an ultra-modern industry has emerged, but gaps in the headquarter functions still exist. They can only be closed within a context of a new technology cycle. From the perspective of unified Germany, the high transfers of 1.3 trillion Euros in the last 20 years, dominantly used for stabilizing social security systems in the East, could mostly be faced out of unification-related additional economic performance in West Germany.

Determinants of Academic-Industry Linkages and Incubator-internal Cooperation Patterns of Incubator Firms: Empirical Evidence from Germany
Michael Schwartz, Christoph Hornych
IWH Discussion Papers,
No. 2,
2009
Abstract
The article examines cooperation patterns of firms located in German business incubators (BIs) and technology centers. Based on cross-sectional data, the study explores the network activities within the tenant portfolio and the academic-industry linkages of the tenant firms. In this respect, we contribute to the literature on the impact of business incubation by explicitly considering differences regarding cooperation patterns between diversified and specialized incubator facilities. Contrary to common assumptions, we do not find a higher propensitiy for incubator-internal cooperation activities for firms located in specialized BIs. However, firms located in specialized BIs show significantly higher propensity to engage in academic-industry linkages compared to firms located in diversified incubators.

Evaluating the German (New Keynesian) Phillips Curve
Rolf Scheufele
IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

Business Cycle Forecast, Summer 2008: Price Hikes and Financial Crisis Cloud Growth Prospects
Wirtschaft im Wandel,
No. 7,
2008
Abstract
In the summer of 2008 the turmoil on financial markets and that on the markets for energy dim the prospects for the world economy. The acceleration of the oil price hike during the first half of the year has led to an increase in expected inflation and to higher interest rates on capital markets, while stock prices are going down. At the same time, the financial crisis is far from over, and banks in the US and in Western Europe continue in their efforts to consolidate their balance sheets. Thus, the expansion of credit supply will be scarcer in the next quarters. All this means that demand will slow in the developed economies during the next quarters. However, the massive fiscal stimulus will help the US economy to stabilize, and the world economy still benefits from the high growth dynamics in the emerging markets economies. All in all, the developed economies will not reach their potential growth rate before the second half of 2009. In Germany, the upswing comes to a temporary halt during summer of this year. Slowing foreign demand and the oil price hike induce firms to postpone investments, and private consumption, the soft spot of the upswing in Germany, is still sluggish due to high inflation rates that impair purchasing power. For the end of 2008, chances are good that growth in Germany accelerates again, because German exporters are still penetrating emerging markets as competitiveness does not diminish. All in all, the German economy will grow by 2.3% in 2008 (mainly due to the very high dynamics at the beginning of the year) and by 1.3% in 2009. A main risk of this forecast is that monetary policy fails in easing the high inflationary pressures. As to fiscal policy, efforts to reach sustainable public finances should not weaken.

Technologie- und Gründerzentren im Lichte von Diversifizierung versus Spezialisierung
Michael Schwartz, Christoph Hornych
IWH Discussion Papers,
No. 7,
2008
Abstract
In Germany, a growing tendency can be observed to focus business incubators (BIs) and technology centers and their respective support elements and processes as well as the selection criteria applied by the incubator management on firms from solely one sector or few but complementary sectors and their specific needs and requirements. These are called specialized business incubators (SBIs). Despite the increasing importance of specialization strategies of business incubators as local and regional policy instruments, there are no reliable empirical examinations of the specifics, and advantages in particular, of SBIs compared to more diversified BIs. On the basis of survey-data, that comprises responses from 161 actual firms incubated in 13 diversified BIs and 13 specialized BIs in Germany, this study investigates the mechanisms within the specific context of specialized BIs and their value-added contribution versus the more diversified incubation model. For the first time, this study provides large-scale empirical evidence concerning the effects of adopting a specialization strategy in the context of business incubation.

Deeper, Wider and More Competitive? Monetary Integration, Eastern Enlargement and Competitiveness in the European Union
Gianmarco Ottaviano, Daria Taglioni, Filippo di Mauro
ECB Working Paper,
No. 847,
2008
Abstract
What determines a country’s ability to compete in international markets? What fosters the global competitiveness of its firms? And in the European context, have key elements of the EU strategy such as EMU and enlargement helped or hindered domestic firms’ competitiveness in local and global markets? We address these questions by calibrating and simulating a conceptual framework that, based on Melitz and Ottaviano (2005), predicts that tougher and more transparent international competition forces less productive firms out the market, thereby increasing average productivity as well as reducing average prices and mark-ups. The model also predicts a parallel reduction of price dispersion within sectors. Our conceptual framework allows us to disentangle the effects of technology and freeness of entry from those of accessibility. On the one hand, by controlling for the impact of trade frictions, we are able to construct an index of ‘revealed competitiveness’, which would drive the relative performance of countries in an ideal world in which all faced the same barriers to international transactions. On the other hand, by focusing on the role of accessibility while keeping ‘revealed competitiveness’ as given, we are able to evaluate the impacts of EMU and enlargement on the competitiveness of European firms. We find that EMU positively affects the competitiveness of firms located in participating economies. Enlargement has, instead, two contrasting effects. It improves the accessibility of EU members but it also increases substantially the relative importance of unproductive competitors from Eastern Europe. JEL Classification: F12, R13.

The Economics of Restructuring the German Electricity Sector
Christian Growitsch, Felix Müsgens
Zeitschrift für Energiewirtschaft,
No. 3,
2005
Abstract
The debate about the development of German electricity prices after the liberalization of energy markets in 1998 raises the question of failures in market restructuring. However, a general statement would be misleading for two main reasons. Firstly, the price development, analyzed for the exemplary case of household prices, shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs. These decreases have been mostly compensated by a significant increase in taxes and subsidies (+56%).

An analysis of household electricity price developments in Germany since liberalization

2005
Abstract
Despite the liberalization of energy markets in 1998, household electricity prices in 2004 are nearly the same as 1998, indicating a failure of market restructuring. However, such a general consideration is misleading for two main reasons. Firstly, the price development shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs.
