Stock Market Firm-Level Information and Real Economic Activity

ECB Working Paper,
No. 1366,

Abstract
We provide evidence that changes in the equity price and volatility of individual firms (measures that approximate the definition of 'granular shock' given in Gabaix, 2010) are key to improve the predictability of aggregate business cycle fluctuations in a number of countries. Specifically, adding the return and the volatility of firm-level equity prices to aggregate financial information leads to a significant improvement in forecasting business cycle developments in four economic areas, at various horizons. Importantly, not only domestic firms but also foreign firms improve business cycle predictability for a given economic area. This is not immediately visible when one takes an unconditional standpoint (i.e. an average across the sample). However, conditioning on the business cycle position of the domestic economy, the relative importance of the two sets of firms - foreign and domestic - exhibits noticeable swings across time. Analogously, the sectoral classification of the firms that in a given month retain the highest predictive power for future IP changes also varies significantly over time as a function of the business cycle position of the domestic economy. Limited to the United States, predictive ability is found to be related to selected balance sheet items, suggesting that structural features differentiate the firms that can anticipate aggregate fluctuations from those that do not help to this aim. Beyond the purely forecasting application, this finding may enhance our understanding of the underlying origins of aggregate fluctuations. We also propose to use the cross sectional stock market information to macro-prudential aims through an economic Value at Risk.

Can Korea Learn from German Unification?
Ulrich Blum
IWH Discussion Papers,
No. 3,
2011
Abstract
We first analyze pre-unification similarities and differences between the two Germanys and the two Koreas in terms of demographic, social, political and economic status. An important issue is the degree of international openness. “Stone-age” type communism of North Korea and the seclusion of the population prevented inner-Korean contacts and contacts with rest of the world. This may create enormous adjustment costs if institutions, especially informal institutions, change. We go on by showing how transition and integration interact in a potential unification process based on the World Bank Revised Minimum Standard Model (RMSM) and on the Salter-Swan-Meade model. In doing so, we relate the macro and external impacts on an open economy to its macro-sectoral structural dynamics. The findings suggest that it is of utmost importance to relate microeconomic policies to the macroeconomic ties and side conditions for both parts of the country. Evidence from Germany suggests that the biggest general error in unification was neglecting these limits, especially limitations to policy instruments. Econometric analysis supports these findings. In the empirical part, we consider unification as an “investment” and track down the (by-and-large immediate to medium-term) costs and the (by-and-large long-term) benefits of retooling a retarded communist economy. We conclude that, from a South-Korean
perspective, the Korean unification will become relatively much more expensive than the German unification and, thus, not only economic, but to a much larger degree political considerations must include the tying of neighboring countries into the convergence process. We finally provide, 62 years after Germany’s division and 20 years after unification, an outlook on the strength of economic inertia in order to show that it may take much more than a generation to compensate the damage inflicted by the communist system.

Identifying Industrial Clusters from a Multidimensional Perspective: Methodical Aspects with an Application to Germany
Matthias Brachert, Mirko Titze, Alexander Kubis
Papers in Regional Science,
No. 2,
2011
Abstract
If regional development agencies assume the cluster concept to be an adequate framework to promote regional growth and competitiveness, it is necessary to identify industrial clusters in a comprehensive manner. Previous studies used a diversity of methods to identify the predominant concentrations of economic activity in one industrial sector in a region. This paper is based on a multidimensional approach developed by Titze et al. With the help of the combination of concentration measures and input–output methods they were able to identify horizontal and vertical dimensions of industrial clusters. This paper aims to refine this approach by using a superior measure of spatial concentration and by integrating information about spatial interdependence of industrial cluster structures to contribute to a more adequate framework for industrial cluster identification.

Finance and Growth in a Bank-Based Economy: Is It Quantity or Quality that Matters?
Michael Koetter, Michael Wedow
Journal of International Money and Finance,
No. 8,
2010
Abstract
Most finance–growth studies approximate the size of financial systems rather than the quality of intermediation to explain economic growth differentials. Furthermore, the neglect of systematic differences in cross-country studies could drive the result that finance matters. We suggest a measure of bank’s intermediation quality using bank-specific efficiency estimates and focus on the regions of one economy only: Germany. This quality measure has a significantly positive effect on growth. This result is robust to the exclusion of banks operating in multiple regions, controlling for the proximity of financial markets, when distinguishing different banking sectors active in Germany, and when excluding the structurally weaker East from the sample.

Regionale Migration in Abhängigkeit von Humankapital und sektoraler Struktur. Eine empirische Analyse am Beispiel von Deutschland und Polen
Alexander Kubis
IWH-Sonderhefte,
No. 2,
2010
Abstract
Die vorliegende Promotionsschrift von Dipl.-Volkswirt Alexander Kubis über deutsch-polnische Migrationsmuster und die Möglichkeiten, künftiges Wanderungsverhalten regional differenziert zu prognostizieren, ordnet sich in die Tradition der Arbeiten des IWH ein, die sich mit der Interdependenz transformationsökonomischer Entwicklungen und der europäischen Integration befassen. Die Verzahnung beider Aspekte ist bei Wanderungen besonders explizit, weil der Umbau von staatlich gelenkten Planwirtschaften zu Marktwirtschaften regional und sektoral mit unterdurchschnittlichen Geschwindigkeiten ablief, weshalb eine erhebliche Dynamik in den Veränderungen dessen, was man als Chancenverteilung im Raum bezeichnen möchte, konstatiert werden kann – und genau auf diese reagiert Migration. Insbesondere vor dem Hintergrund ursprünglicher Zuwanderungsbeschränkungen und eines nunmehr tatsächlich vorhandenen, aber auch im Bewusstsein präsent werdenden erhöhten Fachkräftebedarfs gewinnt die Analyse regionaler und sektoraler Bestimmungsgründe der Migration eine herausragende Bedeutung.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Annals of Regional Science,
No. 1,
2010
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 externalities resulting from high R&D intensity of the local private sector as well as knowledge from local public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Specialization, Diversity, Competition and their Impact on Local Economic Growth in Germany
Martin T. W. Rosenfeld, Annette Illy, Michael Schwartz, Christoph Hornych
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on urban growth in Germany from 2003 to 2007. We test four elements simultaneously, that is sectoral specialization, diversification of economic activities, urban size as well as the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. The analysis covers manufacturing industries as well as service sectors. Most previous work produces inconsistent results and concentrates on localization economies and/or diversification, while urban size and the effect of local competition are widely ignored. Our regression results show a U-shaped relationship between localization economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city-level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former a U-shaped relationship is found whereas the effect is inversely U-shaped for the latter.

May Cities in De-Industrialized Regions Become Hot Spots for Attracting Cultural Businesses? The Case of Media Industry in Halle an der Saale (Germany)
Christoph Hornych, Martin T. W. Rosenfeld
European Planning Studies,
2010
Abstract
Policy-makers from many regions where old industrial structures in the field of manufacturing have collapsed are trying to stimulate entrepreneurial activities of businesses in the cultural industry. The question is whether this strategy could be successful. This article examines the strategy of supporting the sector of media industry (“MI”) by policy-makers in the region of Halle in East Germany, where a strong de-industrialization has taken place after the German reunification. Stimulated by the policy-makers' support measures, there actually was a remarkable development of MI. However, the number of MI firms and their employees did not further increase in recent years, after having reached a certain level. This illustrates the limits of political measures for turning a city's path of industrial development voluntarily.

The Manufacturing Sector in East Germany on a Path from De-industrialization to Re-industrialization: Are there Economically Sustainable Structures?
Gerhard Heimpold
Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
Der Beitrag untersucht, welche Entwicklung die ostdeutsche Industrie in der Zeit nach dem Übergang in die Marktwirtschaft genommen hat und ob die hinter den wirtschaftlichen Ergebnissen stehenden Faktoren und Strukturen Merkmale wirtschaftlicher Nachhaltigkeit aufweisen. Gemessen an den wirtschaftlichen Ergebnissen wurde seit Beginn der 90er Jahre viel erreicht: Die Bruttowertschöpfung ist auf das Zweieinhalbfache gestiegen, die industrielle Produktivität liegt bei reichlich vier Fünfteln des westdeutschen Vergleichswertes. Die Produktivitätssteigerung allerdings ging mit einer Halbierung der Industriebeschäftigung im Zeitraum von 1991 bis 2008 einher, trotz eines leichten Zuwachses in den Jahren 2006 bis 2008. Die Lage und Entwicklung der Industrie in den einzelnen Neuen Ländern stellt sich allerdings sehr unterschiedlich dar. Beim industriellen Beschäftigtenbesatz liegt das Bundesland Thüringen vor einigen westdeutschen Bundesländern.
Bei den hinter den Ergebnissen stehenden Faktoren und Strukturen deutet nicht alles auf ökonomische Nachhaltigkeit hin. Zwar wurde im Vergleich zur westdeutschen Industrie überdurchschnittlich viel in die Modernisierung des Sachkapitalstocks investiert, und beim Humankapital verfügt die ostdeutsche Industrie über einen Anteil von Beschäftigten mit Hoch- und Fachschulabschluss, der jenem in Westdeutschland entspricht. Doch bei den Forschungs- und Entwicklungs-(FuE-)Aktivitäten, die für ökonomisch nachhaltige, sprich zukunftsgerichtete, Industrieaktivitäten stehen, offenbaren sich gemessen an wichtigen Inputgrößen Defizite. Letztere resultieren aus den strukturellen Besonderheiten der ostdeutschen Industrie, zu denen nicht zuletzt die Dominanz kleiner und mittlerer Unternehmen und das Fehlen größerer Unternehmen gehören. Mit der inputseitig schwach ausgeprägten FuE im Unternehmenssektor korrespondiert ein vergleichsweise geringer Anteil technologieintensiver Branchen, während der Anteil arbeitsintensiver Branchen höher als in den Alten Bundesländern ausfällt. Ein weiterer Wandel hin zu nachhaltigeren Industriestrukturen wird also nottun. Denn aus wachstumstheoretischer Sicht lässt sich ein dauerhafter Wachstumspfad hauptsächlich mit technologieintensiven Produktionen verwirklichen. Arbeitsintensive Branchen stehen dagegen im internationalen Wettbewerb besonders unter Kostendruck. Auch die funktionalen Strukturen offenbaren in puncto ökonomischer Nachhaltigkeit Defizite. Der Anteil von Beschäftigten in industriellen Fertigungsfunktionen liegt über den westdeutschen Verhältnissen, und jener in hochwertigen -Dienstleistungs- ebenso wie in den übrigen Dienstleistungsfunktionen liegt darunter. Dies weist erneut auf den Mangel an Unternehmen mit Führungsfunktionen in den Neuen Ländern hin. Will die ostdeutsche Industrie auf dauerhaftem Wachstumskurs bleiben, wird demnach ein weiterer Strukturwandel zugunsten technologie- und humankapitalintensiver Produktionen erforderlich sein, den die Wirtschaftspolitik durch günstige Rahmenbedingungen unterstützen sollte.

Is the European Monetary Union an Endogenous Currency Area? The Example of the Labor Markets
Herbert S. Buscher, Hubert Gabrisch
IWH Discussion Papers,
No. 7,
2009
Abstract
Our study tries to find out whether wage dynamics between Euro member countries became more synchronized through the adoption of the common currency. We calculate bivarate correlation coefficients of wage and wage cost dynamics and run a model of endogenously induced changes of coefficients, which are explained by other variables being also endogenous: trade intensity, sectoral specialization, financial integration. We used a panel data structure to allow for cross-section weights for country-pair observations. We use instrumental variable regressions in order to disentangle exogenous from endogenous influences. We applied these techniques to real and nominal wage dynamics and to dynamics of unit labor costs. We found evidence for persistent asymmetries in nominal wage formation despite a single currency and monetary policy, responsible for diverging unit labor costs and for emerging trade imbalances among the EMU member countries.
