Evaluating communication strategies for public agencies: transparency, opacity, and secrecy
Axel Lindner
IWH Discussion Papers,
No. 8,
2008
Abstract
This paper analyses in a simple global games framework welfare effects stemming
from different communication strategies of public agencies if strategies of agents are complementary to each other: communication can either be fully transparent, or the agency opaquely publishes only its overall assessment of the economy, or it keeps information completely secret. It is shown that private agents put more weight to their private information in the transparent case than in case of opacity. Thus, in many cases, the appropriate measure against overreliance on public information is giving more details to the public instead of denying access to public information.

Shrinking due to corpulence? BMI in childhood predicts subsequent linear growth among US children and youth, 1963-1970
Marco Sunder
Annals of Human Biology,
2008
Abstract
While the USA is one of the most opulent countries, its population is not among the tallest but is among the most corpulent. This short report investigates the association between body mass index in childhood and subsequent change in height-for-age at the individual level, based on data from the National Health Examination Study (1963-1970). A sub-sample of participants in this survey was measured twice at intervals between 2.3 and 4.4 years, and assessed bone age can be used to account for differences in maturation at baseline. Regression results indicate that a BMI-for-age above the 85th percentile is associated with a reduction in growth by 0.03-0.06 height-for-age standard deviations per year, or roughly 1 cm within 4 years. An inefficiently high nutritional status in childhood may thus jeopardize subsequent linear growth. However, the trans-Atlantic height gap is considerably larger than what this empirical relationship could predict.

Wie effektiv sind Technologie- und Gründerzentren in den Neuen Bundesländern?
Michael Schwartz
List Forum für Wirtschafts- und Finanzpolitik,
2008
Abstract
In Eastern Germany, since the beginning of the 1990s technology centers and business incubators are established by cities and municipalities to provide a favorable business environment for young and newly founded innovative firms. Right from the beginning, the effectiveness of these support facilities has been the subject of intense academic and policy discussions, but empirical evidence on the actual effectiveness of these centers is limited so far. Taking into account that the choice of the appropriate criteria for evaluations of the effectiveness of technology centers and business incubators is far from clear cut, this article focuses on three core indicators that are generally accepted as measures for effectiveness (incubation time, share of newly founded firms in the tenant portfolio and technological level of the supported firms), and analyses for five business incubators in East Germany whether they can be characterized as being effective policy instruments. A positive assessment of the five incubators’ effectiveness can be made with regard to average incubation time of tenant companies, as well as insofar the share of newly founded firms on all supported companies is concerned. However, deficiencies are found regarding the technological level of the incubator firms.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
No. 58,
2008
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Capital Stock Approximation using Firm Level Panel Data: A Modified Perpetual Inventory Approach
Steffen Müller
Jahrbücher für Nationalökonomie und Statistik,
No. 4,
2008
Abstract
Many recent studies exploring conditional factor demand or factor substitution issues use firm level panel data. A considerable number of establishment panels contains no direct information on the capital input, necessary for production or cost function estimation. Incorrect measurement of capital leads to biased estimates and casts doubt on any inference on output elasticities or input substitution properties. The perpetual inventory approach, commonly used for long panels, is a method that attenuates these problems. In this paper a modified perpetual inventory approach is proposed. This method provides more reliable measures for capital input when short firm panels are used and no direct information on capital input is available. The empirical results based on a replication study of Addison et al. (2006) support the conclusion that modified perpetual inventory is superior to previous attempts in particular when fixed effects estimation techniques are used. The method thus makes a considerable number of recently established firm panels accessible to more sophisticated production function or factor demand analyses.

Export Promotion Needs the Disclosure of Industrial Potentials – A Case Study for the Federal State of Thuringia
Udo Ludwig, Brigitte Loose, Cornelia Lang
Wirtschaft im Wandel,
No. 5,
2008
Abstract
In countries and regions with weak domestic markets, the orientation towards external markets plays an important rule. This applies even more for economies emerging from the transformation process from a state to a market economy with a small export sector and a continuous decline in the number of residents. The federal state Thuringia presents such an example. There is still a large gap in exports compared to Germany as a whole. The paper deals with the role of exports in economic development and economic measures to increase the export activities of small and medium-sized companies (SMEs) in Thuringia. The study is based on a survey among SMEs in Thuringia on the performance of exporters and non-exporters. One of the main findings shows that export promotion was important only for one among three exporting companies during the last three years. That speaks for the confidence of the firms in their own power. The most measures used to implement or advance export activities are participation in a fair, information sessions on foreign markets and two general instruments to support companies: investment and innovation stimulation. As a result, economic measures make sense, but it should not depend on the age or the size of a company. Besides, the support should not only be given by department of foreign trade, but also by other departments. Finally, especially newcomers should be supported to entry foreign markets.

International Financial Integration and Stability: On the Causes of the International Banking Crisis 2007/08 and Some Preliminary Lessons.
Diemo Dietrich, Achim Hauck
Wirtschaft im Wandel,
No. 5,
2008
Abstract
Since its beginning, the recent financial market turmoil that has come to be known as the „subprime crisis“ has provoked considerable controversy among both, policymakers and scientists. The debate mainly focuses on two questions. The first is whether and how short-term measures should be taken to stabilize the global financial system. The second is which general lessons can be drawn from this crisis. Up to now, several potential causes of the crisis have been discussed in a more or less isolated manner. However, a predominant source of the crisis has not been identified yet. Accordingly, there is still a lack of knowledge regarding general consequences of the crisis for economic policy.
The purpose of this article is twofold. First, we show that to a large extent the crisis is due to the economic integration of formerly peripheral countries into the world economy that led to significant savings and investment imbalances. Thus, we argue that the crisis not only is a global phenomenon in its effects but also has global roots. Based on this argument, the second purpose of our paper is to derive implications for economic policy, where we also discuss the consequences for the future design of the global financial architecture.

Economic Upswing and Vitalization of the Labor Market – Who Gains From the Upswing?
Herbert S. Buscher
Wirtschaft im Wandel,
No. 5,
2008
Abstract
The current situation with respect to the economic development in Germany may be characterized as somewhat suppressed as opposed to euphoric. And this statement holds although the German economy is in an upswing phase since 2005, and the GDP growth rates clearly exceed 2% per annum. The main driving forces of this upswing are mainly from the German exports as well as the domestic investment decisions. Rather underdeveloped compared with the exports and the investment is private consumption. This development is accompanied by positive signals from the German labor market. Declining unemployment figures, increasing regular employment and a smaller number of people in active labor market policy measures are the accompanying positive signals from the labor market. But this in general positive development has not yet reached widespread groups of employees in the sense that their real income has also risen and they thus can dispose of a higher amount of purchasing power. This time lag in the different developments between employment and income may lead to a situation that perceived and actual developments may differ and that actually, there might be a gap between the two. The paper discusses what could be meant with „perceived” development and reaches to the conclusion that actual and perceived developments are not so far away from each other than one might have expected.

Consequences of the US-subprime Crisis Dampen Economic Growth in Germany
Wirtschaft im Wandel,
1. Sonderausgabe
2008
Abstract
The crises of the housing and the financial sector in the US and the turmoil on worldwide financial markets have clouded the prospects of the world economy for this and next year. In particular, conditions for financing consumption and investment will worsen. In addition, the price hikes for energy and food entail a redistribution of purchasing power from ordinary households to the producers of these goods. As a consequence of all this, the economy in the US will be more or less stagnating this year, and world growth will slow down. Firms in the nonfinancial sector, however, are generally in good financial condition, policy in the US takes strong measures to contain the crisis, and growth dynamics in emerging markets economies appear to be robust enough to withstand the dampening effects. In Germany, the economy is, in spite of the adverse effects from abroad and in particular the strong appreciation of the euro, still in good shape. Apparently, the economy has become more robust in the past years, partly due to increased competitiveness of German producers. Still, economic expansion will slow down, with annual growth rates of 1.8% for this year and 1.4% for 2009.
For the first time the forecast of the institutes comprises a medium term projection. For this, the potential growth rate of the German Economy is estimated to be 1.6%. As to policy recommendations, the institutes advise against the establishment of minimum wages in Germany, because they fear adverse effects for employment. In this point the IWH and its partners take a different view.

Regional origins of employment volatility: evidence from German states
Claudia M. Buch
CES IFO Working Paper No. 2296,
2008
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.
