German Economic Growth in 2008: Temporary Slow Down
Wirtschaft im Wandel,
No. 4,
2008
Abstract
World economic growth has slowed in the first months of 2008. The main causes are the crisis in the US housing sector and the turmoil in the financial sector in general, the spreading expectation of a recession in the US, and sharply rising prices for energy and food. The German economy, though, is still expanding healthily, with strong investment and export activities. Private consumption, however, shrank at the end of 2007. In 2008, while favorable labor market conditions will improve job security and thus the propensity to consume, real incomes will not rise by much due to the risen inflation rate; consumption will again expand only modestly this year. A slower expansion of the world economy and the stronger euro will dampen exports and investment. All in all, growth will slow to (working-day adjusted) 1.2% in 2008. Chances are good that in the next year, after the negative shocks have faded out a bit, growth will be accelerating again. The East German Economy was on a lower growth path in 2006 and 2007 than the economy in the West, according to recently revised national accounts data. Industrial production, however, is more dynamic in the East. Unemployment rates will continue to decrease faster in the East: as in the rest of Germany, employment is growing, and, contrary to what happens in the West, the labor force is shrinking.

Revision des neoklassischen Wachstumsmodells - Sind alle Lehrbücher falsch?
Wolfgang Cezanne, Mirko Titze, Lars Weber
WiSt - Wirtschaftswissenschaftliches Studium,
No. 9,
2006
Abstract
Das neoklassische Wachstumsmodell von Solow aus dem Jahr 1956 gehört heute immer noch zu den wichtigsten Wachstumstheorien. Die heute gelehrten Formen, die sich in nahezu allen volkswirtschaftlichen Lehrbüchern befinden, verletzen jedoch einen wichtigen Zusammenhang aus der volkswirtschaftlichen Gesamtrechnung: die Identität von Nettoinvestitionen und Ersparnis. Die Lösungen der Lehrbuchmodelle widersprechen damit der ursprünglichen Solow-Lösung. Der vorliegende Beitrag zeigt die Konsequenzen dieser Ungenauigkeiten auf. Darüber hinaus wird ein Modell präsentiert, das die Identität von Nettoinvestitionen und Ersparnis wahrt und folglich mit der Solow-Lösung vereinbar ist.

National Accounting revision certifies stronger growth of production for the New Laender

No. 4,
2006
Abstract
Nach der jüngsten Revision der Volkswirtschaftlichen Gesamtrechnungen wurde in den neuen Bundesländern in den Jahren 2001 bis 2004 mehr produziert als bislang bekannt war. Das Niveau der Wertschöpfung wurde stärker als im gesamtdeutschen Durchschnitt angehoben, obwohl es bei einigen Wirtschaftsbereichen, wie dem Kredit- und Versicherungsgewerbe und der Wohnungsvermietung, zu einer Absenkung kam. Auch das Wachstumsbild hat sich geändert. Das Bruttoinlandsprodukt ist in den Jahren 2001 bis 2004 stärker gestiegen als zuvor berechnet worden war, darunter drei Jahre in Folge auch kräftiger als in den alten Bundesländern. Der Rückstand in der Pro-Kopf- Produktion wurde verringert Allerdings kam dieser Prozeß wegen der Produktionsschwäche im Jahr 2005 – zumindest vorübergehend – wieder zum Erliegen.

The Contestable Markets Theory - Efficient Advice for Economic Policy
Christian Growitsch, Thomas Wein
External Publications,
2004
Abstract
During the nineties of the last century several formerly monopolistic markets (telecommunication, electricity, gas, and railway) have been deregulated in Germany based on European directives and theoretically inspired by the theory of contestable markets. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit possible without any costs, and the price adjustment lag exceeding the entry lag. Our analysis shows that if the incumbent reduces its prices slowly (high adjustment lag) and the market entry can be performed quickly (low entry lag), a new competitor will be able to earn back sunk costs. Therefore it is not necessary that all three conditions be complied with for potential competition to exist. Applying this „revised“ contestable market theory to the deregulated sectors in Germany, natural monopolies can be identified in telecommunication sections local loops and local/regional connection networks, in the national electricity grid and the regional/local electricity distribution networks, in the national and regional/local gas transmission/distribution sections, and in the railroad network. These sections are not contestable due to sunk costs, expected high entry lags and a probably short price adjustment lag. They are identified as bottlenecks, which should be regulated. The function of system operators in energy and railroad are closely related to the non-contestable monopolistic networks.

Current economic situation: A silver lining on the horizon
Wirtschaft im Wandel,
No. 12,
2003
Abstract
The Federal Statistical Office has recently released the figures for second quarter GDP and its components. At the same time, the data for the past four years has been revised. This made it necessary to update the existing IWH-forecasts for 2003 and 2004. Stimulated by an improving world economy GDP will not decline this year but merely stagnate. In 2004 the external stimulus will further increase and accounting for the additional working days economic activity will rise by 1.8%. The turnaround at the labour market will not take place before the second half of 2004. Fiscal policy is currently aiming to balance the budget, but so far the government tried to achieve this goal by increasing levies and taxes. In order to maintain the growth potential, a sustainable consolidation, though, should work by means of cutting expenditure. Overall the deficit will be 4.1% and 3.9% of nominal GDP in this and next year, respectively.

A revised theory of contestable markets : applied on the German telecommunication sector
Christian Growitsch, Thomas Wein
External Publications,
No. 275,
2002
Abstract
Despite the scepticism raised by the German Monopoly Commission our analysis shows that the revised theory of contestable markets can be applied to the telecommunications market better than expected. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit is possible without any costs, and the price adjustment lag exceeds the entry lag. Our analysis shows that if the incumbent reduces its prices slowly (high adjustment lag) and the market entry can be performed quickly (low entry lag), a new competitor will be able to earn back sunk costs. Therefore it is not necessary that all three conditions are satisfied for potential competition to exist. We applied the ‘revised’ contestable market theory to the German telecommunication market and have been able to clearly identify the value added stages in which regulation is required. Under the present conditions local loops - which can be determined as natural monopolies - are not contestable due to sunk costs, high entry lags expected and a probable short price adjustment lag. Local loops can be identified as monopolistic bottlenecks therefore. Regional and local connection networks should also be regulated because a high entry lag and a low price adjustment lag have to be expected as well as current competition does not exist today. The national connection network shows current competition between several network providers; hence regulation can be abolished in this field. Assumed that network access is regulated, services can be supplied by several competing firms.

International economic development still impedes growth in Central and Eastern Europe
Axel Brüggemann
Wirtschaft im Wandel,
No. 3,
2002
Abstract
The world wide economic slow down has increasingly affected the transition economies. Lower demand in Western Europe for exports from Central and Eastern Europe has depressed industrial production and growth in the region. Strong domestic demand has managed to offset some of the negative external influences. In total the countries in Central and eastern Europe will grow with 3,1 % in 2002 and with 4,1% in 2003. The higher growth in 2003 results from the combination of a continuing strong domestic demand and amore favourabel external environment, as the world economy starts to recover in the second half of 2002. Inflation will continue to slow, while unemployment decreases only marginally. Higher growth will also lead to higher current account deficits.
The slowdown in 2001 has increased the risk potential for financial crises in Central and Eastern Europe. The forecast is build upon the assumption that no such crisis will occur, if a crisis does errupt the forecast will have to be revised downwards. The regular anlysis carried out by the IWH regarding the development of the risk potential, indicate particular high risks for Poland and to a somewhat lesser extent also for Hungary. As the unfavourable external economic conditions will persist for the coming months, a further increase in the risk potential can be expected.
