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...

The IWH signals approach: the present potential for a financial crisis in selected Central and East European countries and Turkey
Hubert Gabrisch, Simone Lösel
Wirtschaft im Wandel,
No. 8,
2006
Abstract
The steep increase of oil prices, general threats rooting from Iran’s nuclear program, and doubts about the future policy of important central banks recently caused more uncertainties of investors on international financial markets. This explains the higher volatility and the fall of indices on stock markets including those of some Central and East European countries. International investors could respond with adjustments of their portfolio and trigger off a financial crisis. On this background, the article studies the potential for a financial crises in the region mentioned. The analytical tool is the IWH signals approach. The study concludes that the risk of the outbreak of a financial crisis within the next 18 months is rather unrealistic in most countries. A stable economic policy, high real growth rates, a financial system already robust compared to earlier times of transition, and appropriate exchange rate arrangements protect the countries against speculative attacks and portfolio adjustments. When the composite indicator shows deterioration like in the Baltic countries, it turned out to be negligible. For the Slovak Republic and Slovenia, the composite indicator even improved. A closer look to individual indicators reveals still some problems in the banking sectors of the Czech Republic, Poland, and Hungary, however, without out major impact on the composite indicator.
This general assessment does not apply to Romania, and, in particular, to Turkey. The composite indicator signals a significant increase of the risk potential for the next 18 months in both countries. There is a considerable need for sound policy action.

Ein kubischer Spline zur temporalen Disaggregation von Stromgrößen und seine Anwendbarkeit auf Immobilienindizes
Albrecht Kauffmann, A. Nastansky
Statistische Diskussionsbeiträge der Wirtschafts- und Sozialwissenschaftlichen Fakultät, Universität Potsdam, Nr. 22,
No. 22,
2006
Abstract
Das Geschehen auf den regional sehr heterogenen Immobilienmärkten ist vor dem Hintergrund stark steigender Preise für Wohn- und Gewerbeimmobilien in den letzten Jahren in weiten Teilen Europas und der Welt stärker ins das Blickfeld der Allgemeinheit sowie der wirtschaftspolitisch Handelnden, insbesondere der Zentralbank, gerückt. Mit einem Anteil von rund 50% nimmt das in Immobilien gebundene Vermögen eine dominierende Stellung im Brutto-Volksvermögen der privaten Haushalte in Deutschland ein. Schwankungen im Wert dieses Eigentums beeinflussen das Verhalten der Haushalte auf den Faktor- und Gütermärkten. So können Vermögenseffekte – hervorgerufen durch steigende oder fallende Immobilienpreise – den Konjunkturverlauf über die Konsumnachfrage positiv wie negativ stimulieren. Überdies kann die Stabilität des Finanzsystems infolge übermäßiger Bewegungen in den Immobilienpreisen und damit einhergehenden Forderungsausfällen von Hypothekendarlehen gefährdet werden. Angesichts der herausragenden volkswirtschaftlichen Bedeutung zeichnet sich jedoch der deutsche Immobilienmarkt auf Grund eines fehlenden amtlichen Berichtssystems durch eine geringe Transparenz aus. Die amtliche Statistik beschränkt sich auf die Erhebung und Veröffentlichung von Preisen für Bauland, Baupreise für Wohngebäude sowie die Mietpreisentwicklung von Wohnimmobilien. Privatwirtschaftliche Institutionen versuchen diese Nische durch die Erhebung eigener Daten und Veröffentlichung von Indizes zu besetzen. Ein Index, der das Preisgeschehen auf den Wohn- und Gewerbeimmobilienmärkten in Deutschland auch unterjährig abbildet, fehlt aber weiterhin.
Die temporale Disaggregation von Jahresdaten kann mittels Regression auf Zeitreihen, die die geforderte Periodizität aufweisen, erfolgen. Soll aber auf die Zuhilfenahme weiterer Daten verzichtet werden, bieten sich deterministische Verfahren an. Diesen sind auch die kubischen Splines zuzurechnen, deren Verwendung in der Literatur gelegentlich – ohne Erläuterung der Methodik und ohne Diskussion der mit ihrer Anwendung verbundenen Probleme, bzw. entsprechende Verweise auf die existierende Literatur – erwähnt wird.

Excessive wage increases dampen capital spending
Klaus Weyerstraß
Wirtschaft im Wandel,
No. 16,
2003
Abstract
Considering the debate about the opposite effects of rising wages for employee’s income and employer’s costs, the relationship between wage changes and investment is being investigated on an econometric basis for the years 1971 to 2003. The results show that the dynamics of investment activity slows down as real wages rise more than productivity increases.

Explaining Investment Trends in European Union Countries
Klaus Weyerstraß
IWH Discussion Papers,
No. 174,
2003
Abstract
In the 1980s and, in particular, in the 1990s the countries of the European Union experienced divergent developments of gross fixed capital formation. Estimating an investment function for a panel of ten countries and analyzing the paths of the determinants of investment in the countries under consideration reveals that the different development of final demand is the main factor responsible for the divergences in investment. Other factors are disparities in the decline of real interest rates and of relative prices for capital goods.

Economic Development 2002 and 2003: Investments – The Achilles Heel of the Economy
Wirtschaft im Wandel,
No. 10,
2002
Abstract
The Article analyses and forecasts the economic developments for the World and German in 2002 and 2003. During the winter 2001/2002 the World Economy was able to pull out of its trough. Nonetheless, the upswing did not reach investments and was mainly driven by consumption and exports in the USA and the remaining major economies, respectively. In the course of this and next year Investors will gradually regain their trust in the economy. The same will be the case for consumers in Germany and Europe. As a result a modest recovery on a wide front will develop. In the course of next year this recovery will start to weaken. In Germany, Wage Policy has retracted from its former moderate stance. Hence, although due to the improving economic conditions and the resulting slowed employment cuts by the end of 2002 as well as employment increases in 2003, the upswing on the labour market will not reach the dynamics of the 1999/2000 recovery. Fiscal Policy, caused by the need to consolidate the public budget, will be restrictive. Despite the low inflation risks, by the end of this year the ECB will have raised its major interest rate by 1/2 percentage point. Nonetheless, as interest rates in real terms will remain at relatively low levels a restrictive impact from the Monetary Policy in Germany and the Euro Area will is not expected. The most important Data for the World Economy and Germany are being stated in detailed tables.

What can a town achieve today? Integration, urban regimes, and the acceptance of models
Peter Franz
IWH Discussion Papers,
No. 56,
1997
Abstract
Since 1990, the date of German reunification, urban development and especially the recovery of inner cities in East Germany has been delayed by several factors including real estate restitution claims, inflexible preservation codes for historic buildings, and the shortage of stores for retailers. This blockade situation has resulted in the quick and intensified development of shopping centres as „inner city substitutes“ on the urban periphery. The combined effect of the factors preventing revitalisation strategies and the newly realised and practised potential for autonomous action by the authorities of smaller municipalities was a severe restriction for the governing capacities of the authorities of the larger cities. in regaining their governance capability city governments are dependent on urban groups joining and supporting public developmental strategies. In accordance with Stone (1993) and Stoker and Mossberger (1994) urban groups active in urban development policy can be described as urban regimes. In Germany three types of regimes can be differentiated. The cities differ with respect to the political strength and the forms of coalition and conflict between different urban regimes. Specific conditions in East Germany have led to a special regime constellation with a powerful „conservation regime“ on the one hand and a vivid „globalisation regime“ on the other hand. This conflicting constellation results in a developmental blockade. The hypothesis is that a third regime type, the „local alliance“, is missing and still has to be created by practices such as city marketing and city management. Only when this regime building process has advanced will new constellations of political coalitions and compromise become possible and be able to reduce governance problems of city government in the long run.

Explaining Regional Disparities in Housing Prices across German Districts
Lars Brausewetter, Stephan L. Thomsen, Johannes Trunzer
IZA Institute of Labor Economics,
March
2022
Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
