20 Jahre nach dem Vollzug der Einheit stagniert die Wirtschaftsentwicklung des „ostdeutschen Zwillings“ im Vergleich zu westdeutschen Einkommens- und Produktionskennzahlen. Der starke Wachstumsschub bis in die Mitte der 1990er Jahre ebbte ab, und die Wirtschaft verharrt seitdem auf einem Niveau, das 70% bis 80% der westdeutschen Referenzgrößen entspricht. In diesem Beitrag werden zwei voneinander unabhängige Hypothesen überprüft: (i), dass bereits die kommunistische Wirtschaft Ostdeutschlands vor der Einheit auf einem Stagnationspfad war, ganz im Gegensatz zu dem, was andere Untersuchungen ausweisen; (ii), dass eine starke Pfadabhängigkeit existiert und der Umstieg von der Zentralverwaltungs- zur Marktwirtschaft nur diese vorangegangene Stagnationsphase kompensierte, die tiefer liegenden strukturellen Defizite aber nicht löste. Im Falle Westdeutschlands reicht ein stabiler Entwicklungspfad vom 19. Jahrhundert in die Gegenwart. Daher ist die Analyse des ostdeutschen Entwicklungspfads gleichzeitig ökonomisch relevant und wirtschaftspolitisch bedeutsam.

The worldwide upswing has lost momentum, but it will overcome the present slowdown. Monetary policy is overall still accommodative, and growth dynamics continue to be high in emerging market countries. For the euro area, we expect GDP to grow by around 1.9% in 2011 and 1.7% in 2012, not enough to bring the unemployment rate back significantly below 10%. In fact, in a large core region of the euro area the upswing is well under way; this region includes, apart from Germany and some smaller economies, France, Belgium and the Netherlands. However, the crisis of confidence in the ability of EU institutions to master the fiscal crises is a major threat to the continuation of the upswing.

The focus of this article is the empirical identification of factors influencing Foreign Direct Investment (FDI) in transition economies on a regional level (NUTS 2). The analysis is designed as benchmark between three neighboring post-communist regions, i.e. East Germany, the Czech Republic and Poland. Their different transition paths have not only resulted in economic differences. We can also observe today that the importance of pull factors for FDI varies significantly across the regions. This analysis shows that in comparison with Poland and the Czech Republic, East Germany’s major benefit is its purchasing power, its geographical proximity to West European markets, and its modern infrastructure. Furthermore, the analysis suggests that intra-industry linkages such as specialization and agglomeration economies are relevant factors for the location decision of foreign investors. This result can help to explain the regional divergence of FDI streams in transition economies.

This paper examines the properties of qualitative inflation expectations collected from economic experts for Germany. It describes their characteristics relating to rationality and Granger causality. An out-of-sample simulation study investigates whether this indicator is suitable for inflation forecasting. Results from other standard forecasting models are considered and compared with models employing survey measures. We find that a model using survey expectations outperforms most of the competing models. Moreover, we find some evidence that the survey indicator already contains information from other model types (e. g. Phillips curve models). However, the forecast quality may be further improved by completely taking into account information from some financial indicators.

The aim of this paper is to explain the evolution of the spatial structures of one particular type of renewable energy in Germany – the photovoltaic (PV) industry. We first demonstrate how environmental movements have contributed to institutional change and government action, leading to changes in the legal and regulative structure in Germany. We describe how these changes opened up a window of locational opportunity (WLO), thus combining the WLO concept with the entrepreneurial opportunity concept. As market entries occurred mainly in Eastern Germany, the paper also explores the factors leading to a concentration of economic activity related to the new PV industry in this part of the country. Based on the WLO concept, we combine this framework with the industrial dynamics literature by Klepper (2007) and illustrate the spatial evolution of the PV industry.

This paper analyses the recession in 2008/2009 in Germany, which is very different from previous recessions, in particular regarding its cause and magnitude. We show to what extent forecasters and forecasts based on leading indicators fail to detect the timing and the magnitude of the recession. This study shows that large forecast errors for both expert forecasts and forecasts based on leading indicators resulted during this recession which implies that the recession was very difficult to forecast. However, some leading indicators (survey data, risk spreads, stock prices) have indicated an economic downturn and hence, beat univariate time series models. Although the combination of individual forecasts provides an improvement compared to the benchmark model, the combined forecasts are worse than several individual models. A comparison of expert forecasts with the best forecasts based on leading indicators shows only minor deviations. Overall, the range for an improvement of expert forecasts during the crisis compared to indicator forecasts is relatively small.

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.

Die deutsche Wirtschaft hat sich im Jahr 2010 kräftig erholt. In der ersten Jahreshälfte zogen der Welthandel und in dessen Gefolge die deutschen Exporte kräftig an. Im Verlauf des Jahres wurde das Wachstum der Wirtschaft

in Deutschland aber zunehmend von der Binnennachfrage gestützt. Nicht nur die Investitionen erholten sich, auch vom privaten Konsum kamen Impulse. So liegt die Zahl der Beschäftigten zurzeit auf einem historischen Höchststand, und die Zahl der Arbeitslosen hat sich im Lauf des Jahres immer weiter zurückgebildet.

Auch mittelfristig wird das wirtschaftliche Wachstum in Deutschland verhältnismäßig hoch sein. Der deutsche Außenhandel erhält weiterhin Impulse vom Welthandel. Wesentlich wird die weitere Entwicklung allerdings von der Binnenwirtschaft bestimmt. So werden die Investitionen in der mittleren Frist deutlich expandieren. Dazu trägt bei, dass das Zinsniveau bis zum Ende des Projektionszeitraums relativ niedrig sein wird. Auch der private Konsum wird zum Wirtschaftswachstum beitragen. Die günstige Lage auf dem Arbeitsmarkt und der

hohe Beschäftigungsstand lassen die Lohnsumme kräftig zunehmen und erhöhen zudem den Grad an Beschäftigungssicherheit. Dies führt dazu, dass die privaten Haushalte ihre Konsumausgaben merklich erhöhen. Alles in allem wird das reale Bruttoinlandsprodukt im Jahr 2011 mit 2,3% und im Jahr 2012 mit 1,7% zulegen. In den Restjahren des Projektionszeitraums wird es mit 1½% steigen.

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.

This paper explores the impact of industrial clusters on regional growth at the German labour market region level using a regional convergence model. Based on the results of an exploratory study of the geography of German industrial clusters, we are able to differentiate the impact of industrial clustering from a horizontal and a vertical perspective while taking regional convergence into consideration. The results indicate that in addition to an all-German process of convergence, a specific East German one can be identified. The different types of industrial clusters show mixed effects within this framework. While vertically isolated industrial clusters have a negative impact on regional growth in this period, positive growth effects can be identified when industrial clusters show an intra-regional vertical interconnectedness.
