Beseitigung struktureller Defizite mit der Gemeinschaftsaufgabe „Verbesserung der regionalen Wirtschaftsstruktur“ – Ein Vergleich der Strategien in den neuen Bundesländern
Mirko Titze
Raumforschung und Raumordnung,
2008
Abstract
The Joint Task “For the Improvement of the Regional Economic Structure” is one of the most important instruments for the “Reconstruction East”. Herein the federal states have an extensive flexibility to define their own kind of industrial policy. Due to their structural deficits this paper is focused on the federal states in East-Germany. A decrease in the budget constrains the governments to improve efficiency of subsidies. However, there is one way to solve this problem: change unselective government aid to regional as well as sectoral government aid. This paper shows that there is no federal state, which has applied this kind of policy forcefully.

Wirtschaftspolitische Beratung im Zeichen der Transformation: das Institut für Wirtschaftsforschung Halle
Ulrich Blum, Martin T. W. Rosenfeld
Zeitschrift für Politikberatung,
2008
Abstract
The paper analyzes the role of scientific policy advice in modern democratic societies in general and the role of the Halle Institute for Economic Research as one of the major German economic research institutes in particular. It shows that public funded institutions must be politically independent in order to turn theory and evidence based knowledge into political advice. Typical communication channels are contract research and public hearings as well as publications in economic policy journals, a frequent presence in other print media, radio, television and internet.
The Halle Institute for Economic Research focuses on macroeconomic analyses and forecasting. In addition it scrutinizes structural change and transformation processes from a regional, innovation system, competition and urban perspective.

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.

Business cycle forecast 2008: German upswing takes a break
Wirtschaft im Wandel,
No. 1,
2008
Abstract
Economic growth in the industrial countries will be much more muted in 2008 than in the past year. One cause is the prolonged oil price hike during 2007. The second and more important cause is the intensification of tensions on world financial markets. Due to problems in the financial sector, credit expansion will slow next year in the euro area as well as in the US. This will dampen demand in the real economy. A significant downswing in the industrial countries, however, is not the most likely scenario: in the US, expansive economic policy and a weak dollar that gives production in the US a competitive edge will prevent the economy from sliding into recession. In the euro area, high profitability of firms and structural improvements in the working of labour markets will help the economy cope with the stronger euro and with higher costs of external financing due to the turmoil in the financial sector. In Germany, the upswing has still not reached the demand of private households. The main reason is that real wages were stagnating in 2007 and will not rise by much in 2008, since inflation has accelerated considerably at the end of last year. In addition, weaker dynamics of external demand will dampen export growth. This and the end of tax incentives for investment at the end of 2007 will dampen investment activity. All in all, the economy will slow down in the first half of 2008. However, chances are good that the upswing will only have taken a break: when the dampening external shocks have ceased, the driving powers of the upswing will prevail; dynamic employment growth is a reflection of the strong confidence of firms. A major risk for employment and for the German economy in general is, however, the possibility that the policy concerning the labour markets changes course; bad omens are the recent the introduction of minimum wages for postal services and the announced extension of unemployment benefits for persons older than 50.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

Ageing in East Germany: Remarkable reduction of entrepreneurship
Lutz Schneider, Stefan Eichler
Wirtschaft im Wandel,
No. 4,
2007
Abstract
Population shrinking and ageing are obvious trends in many German regions, but in the Eastern states they reach an unique level. An often ignored economic implication of these demographic deve-lopments is the reduction of the entrepreneurial potential. Shirking, on the one hand, diminishes the quantity of potential entrepreneurs, on the other hand these effects are strengthened by ageing trends, since people usually decide in younger years to found an enterprise. The analysis tries to quantify the impact of demographic change on entrepreneurship activities in east Germany until 2020. At the first stage on the basis of the Mikrozensus survey age specific shares of new entrepreneurs are calculated. In order to obtain a status-quo-forecast of new entrepreneurs at the second stage these quotas are combined with the population projections for the East Germany. As expected the propensity to set up a new business is highest for persons at the age form 25 to 39 years. Due to the strong reduction of this age group the number of new firm foundations will fall by approximately 25% until 2020.Whereas the decline in Berlin will be relatively small (14%), Brandenburg has to bear an alarming reduction of 32%.In contrast the West German states show only a reduction of 6% during the same period, which emphasizes the extraordinary dimension of demographic change in East Germany.

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.

Economies of Scope in European Railways: An Efficiency Analysis
Christian Growitsch, Heike Wetzel
IWH Discussion Papers,
No. 5,
2006
Abstract
In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies – companies owning a network and providing transport services – argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realise economies of joint production and, thus, produce railway services on a higher level of efficiency. To determine whether joint or separate production is more efficient we apply a Data Envelopment Analysis super-efficiency bootstrapping model which relates the efficiency for integrated production to a virtual reference set consisting of the separated production technology. Our findings are that in a majority of European Railway companies exist economies of scope.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.
