Systematic Mispricing in European Equity Prices?
Marian Berneburg
IWH Discussion Papers,
No. 6,
2007
Abstract
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2007-018,
No. 18,
2007
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

Die Lage der Weltwirtschaft und der deutschen Wirtschaft im Frühjahr 2007
Wirtschaft im Wandel,
1. Sonderausgabe
2007
Abstract
In spring 2007, the global economy remains robust. While growth rates have declined slightly from last year, as business activity in the US has slowed, they continue to reflect an upswing, which by now has held on for a notably long time. Especially the developing and emerging countries have been raising output very fast, due in part to their increasing role in the international division of labour. In the industrialised economies, on the other hand, the current recovery has not been remarkably strong. So far the slowdown in the US economy has not spilled over to other regions and the Euro Area as well as Japan continue to expand at a high pace. Here expansive monetary policy provided a notable support. Buoyant financial markets stimulated the world economy additionally, even though market volatility has increased since the end of February. The US central bank’s current concern with inflationary risks keeps it from loosening its slightly restrictive monetary policy. It will be the second half of the year – when price pressures have eased – until the Fed makes its first rate cut. The ECB, on the other hand, has been preparing financial markets for a further increase in interest rates by summer. In 2007 and 2008 the growth disparities in the industrialised countries will diminish. On one hand, the upswing in the Euro Area will start to moderate, as fiscal policy hampers business activity and monetary policy will not stimulate anymore. On the other hand, the US economy will slowly gain pace from summer onwards; the emerging markets will continue to develop in a highly dynamic fashion. World-GDP in this and next year will likely rise by about 3 ¼ % in 2007, which is still faster than in the average of the last ten years. World trade will rise by 7 ½ % in the coming two years. An oil price of 65 US-Dollar and an exchange rate between the Euro and the US-Dollar of 1.32 were assumed for both years 2007 and 2008. The real estate market in the USA continues to be a risk for...

What Determines the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2007-006,
No. 6,
2007
Abstract
We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region. Different measures and estimation approaches lead to rather similar assessments. We find that both spillovers within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector R&D in the respective region. It is not the mere presence and size of public research institutions, but rather the intensity of interactions between private and public sector R&D that leads to high RIS efficiency. We find that relationship between the diversity of a regions’ industry structure and the efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.

Considerable Export Potentials in Eastern Germany
Götz Zeddies
Wirtschaft im Wandel,
No. 2,
2007
Abstract
For a long time, the Federal Republic of Germany is one of the countries with the highest export performance in the world. But a closer examination of East- and West-Germany reveals substantial regional differences. The collabse of the markets in the eastern European countries, which were the main trading partners of GDR, after the breakdown of communism caused a sustainable decline of East-German exports. Nevertheless it was expected that the economic recovery in the former communist countries and the access to new export markets in the western world would cause an upward movement of East-German Trade. Although during the last years East-German exports grew faster than those of Western Germany, the east German share in Germanys total exports is still comparatively low. On the basis of a gravity-model of trade, bilateral export potencials are empirically analysed. This is done for the Federal Republic of Germany as a whole, and seperately forEast and West-Germany. Afterwards, the calculated export potencials are compared with actual exports. The results show that Germany as a whole exceeds its export potencial against the majority of its main trading partners. The differentiated analysis for East and West-Germany supports the hypothesis that Germanys high export performance stems from the western part of the country, whereas the eastern part exploits its export potencial with Germanys main trading partners only to the half. The unexploited export potencials as well as the higher concentration on the fast-growing central and eastern European markets imply considerable potencials for East-German exports to grow in the future.

Zu alt für einen Wechsel? Zum Zusammenhang von Alter, Lohndifferentialen und betrieblicher Mobilität
Lutz Schneider
IWH Discussion Papers,
No. 1,
2007
Abstract
Due to the well known fact of a reduced mobility of older employees the workforce aging will have strong consequences for job mobility in Germany. On the basis of the IAB-Beschäftigtenstichprobe (IABS) the subsequent article analyzes the impact of age on (inter-firm) job mobility. In particular the study answers the question, how wage differentials of a potential job change evolve during the working life span. It is shown, that a job change is less profitable for old than for young workers. However the analysis also demonstrates, that the wage differentials of job changes cannot explain the whole mobility advantage of younger employees.

Schwierigkeiten der Investitionsförderung – Der Fall CargoLifter AG
Mirko Titze
Wirtschaft im Wandel,
No. 12,
2006
Abstract
This paper shows how the state of Brandenburg has subsidized large investments. The Focus of this papers is the case of the CargoLifter AG. The government intended to prevent in the mid 90's the total break-down of the economy in the state of Brandenburg, which is particularly affected by structural changes. This kind of policy is highly controversial casing lengthy discussions. After raising approximately 220 millions of Euro in the capital market and receiving nearly 50 million Euros from the state of Brandenburg the CargoLifter AG run into financial difficulties. The Government subsidized the CargoLifter AG as part of the “Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur - (GA)“. There were arguments to subsidize the CargoLifter AG. This paper analyzes the project management of the company as well as the subsidization with the “Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur - (GA)“of the state of Brandenburg in terms of their contribution to the insolvency of the CargoLifter AG.

Threshold for employment and unemployment. A spatial analysis of German RLM's 1992-2000
Christian Dreger, Reinhold Kosfeld
External Publications,
2006
Abstract
Changes in production and employment are closely related over the course of the business cycle. However, as exemplified by the laws of Verdoorn (1949, 1993) and Okun (1962, 1970), thresholds seem to be present in the relationship. Due to capacity reserves of the firms, output growth must exceed certain levels for the creation of new jobs or a fall in the unemployment rate. While Verdoorn's law focuses on the growth rate of output sufficient for an increase in employment, in Okun's law, the fall in the unemployment rate becomes the focus of attention. In order to assess the future development of employment and unemployment, these thresholds have to be taken into account. They serve as important guidelines for policymakers. In contrast to previous studies, we present joint estimates for both the employment and unemployment threshold. Due to demographic patterns and institutional settings on the labour market, the two thresholds can differ, implying that minimum output growth needed for a rise in employment may not be sufficient for a simultaneous drop in the unemployment rate. Second, regional information is considered to a large extent. In particular, the analysis is carried out using a sample of 180 German regional labour markets, see Eckey (2001). Since the cross-sections are separated by the flows of job commuters, they correspond to travel-to-work areas. Labour mobility is high within a market, but low among the entities. As the sectoral decomposition of economic activities varies across the regions, the thresholds are founded on a heterogeneous experience, leading to more reliable estimates.The contribution to the literature is twofold. First, to the best of our knowledge, no previous paper has investigated a similar broad regional dataset for the German economy as a whole before. By using a panel dataset, information on the regional distributions around the regression lines as well as theirs positional changes is provided for each year. Second, the methods applied are of new type. They involve a mixture of pooled and spatial econometric techniques. Dependencies across the regions may result from common or idiosyncratic (region specific) shocks. In particular, the eigenfunction decomposition approach suggested by Griffith (1996, 2000) is used to identify spatial and non-spatial components in regression analysis. As the spatial pattern may vary over time, inference is conducted on the base of a spatial SUR model. Due to this setting, efficient estimates of the thresholds are obtained. With the aid of a geographic information system (GIS) variation of the spatial components can be made transparent. With Verdoorn’s and Okun’s law the figures show some significant patterns become obvious over time. In respect to Verdoorn’s law, for instance, a stripe of high values in the north-western part from Schleswig-Holstein via Lower Saxony and North Rhine Westfalia to Rhineland Palatinate is striking in all years but 1994 and 1995. In most periods the spatial component is likewise concentrated in Saxony. Clusters of low values can be found in northern Bavaria and, in some periods, in Thüringen and Mecklenburg-Vorpommern. Other parts of Germany appear to be more fragmented consisting of relative small clusters of low, medium and high values of the spatial component. With Okun’s law some changing spatial patterns arise. In all, spatially filtering provides valuable insights into the spatial dimensions of the laws of Verdoorn and Okun.

Prekäre Einkommenslagen ind Deutschland - ein Ost-West-Vergleich 1996-2002
Herbert S. Buscher, Juliane Parys
Allgemeines Statistisches Archiv,
No. 4,
2006
Abstract
The paper investigates the distribution of equivalence-weighted net household income for West and East Germany, covering the period from 1996 to 2002. The data set used is the annual cross section data set “Mikrozensus”. The main issues of the paper are twofold. First, we analyze standard measures of income distributions as well as measures of inequality. Second, we set up a Logit model to explain relative poorness in East and West Germany using Mikrozensus data to capture household characteristics. The main focus in this section deals with the question how different types of forms of living and the number of children will affect the risk of falling into precarious income situations. The results show that the risk of getting poor is higher for families with children as well as for single persons with children.

Local Public Utilities' Profits and Municipal Expenses in Germany: An Empirical Analysis
Peter Haug, Birger Nerré
Proceedings of the 99th Annual Conference on Taxation (November 16-18), Washington DC,
2006
Abstract
German municipalities are currently struggling with growing budget deficits and other financial hardships. From a public choice point of view it seems tempting for vote-maximizing local governments to raise revenues from sources which create fiscal illusion or allow tax exports. An increasingly important revenue source of this kind are profits of local public utilities. In this paper we try to fill an empirical gap and provide data of the development of the profitability over time for selected German local public utilities. Furthermore, we develop and estimate a municipal expenditure function for a panel data set of large German cities . We found some slightly positive relationship between per capita expenses of the municipality and the disposable per capita profits of the local public utilities. This indicates that probably the German municipalities – according to our theoretical considerations – tend to burden their citizens as well as non-voters outside their boundaries with implicit taxes to satisfy their increasing financial needs.
