Abstract
This paper describes the IWH macroeconometric model, a quarterly structural model for the German Economy. It focuses on the specification and estimation on supply-side aspects of the model. This approach guarantees a theoretical derived long-run model equilibrium. It combines short-run forecasting requirements with a long-run theoretical foundation. For some macroeconomic aggregates short- and long-run effects of supply- and demand shocks are illustrated. Additionally, effects of external shocks are investigated through model simulations to illustrate aggregate model characteristics.

Ageing in East Germany: Remarkable reduction of entrepreneurship

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.

International economic development still impedes growth in Central and Eastern Europe

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.
