We study state dependence in the German welfare system and compare transition patterns before and after recent reforms of the welfare system (Hartz Reforms). Using data from the German Socio-Economic Panel, we apply dynamic multinomial logit estimators and find that welfare transitions have...

This paper analyzes the effects of short-time work (i.e., government subsidized working time reductions) on unemployment and output fluctuations. The central question is whether short-time work saves jobs in recessions. In our baseline scenario the rule based component of short-time work (i.e.,...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

The paper will present some estimates of the potential macro- and regionaleconomic effects for the German economy from hosting the football world cup 2006. The results have been prepared in the years 2000 and 2001 using the sport-economic simulation model SPORT (Ahlert 2001). The model has a...

The global dimension of environmental problems stresses the need of an internationally linked environmental environmental policy. The example of climate change policy shows, that environmental policy has to be a subject of a globally oriented international policy formulating operational targets...

In 1999 the red/green administration in Germany induced an ecological tax reform, which burdens energy consumption and uses the tax revenue to reduce social security distributions. As in other countries the design of the taxation does not follow textbook considerations, but is marked by many...

We have combined a simple demographic model and the 58 sector econometric simulation and forecasting model INFORGE (Interindustry Forecasting Germany) which has been successfully used in different areas, e.g. modelling the effects of CO2 taxes and the liberalisation of the IT market on the...
