The Tax-Transfer-Simulation-Model (STSM) is a microsimulation model used for the empirical analysis of the effects of taxes, statutory social security contributions and social transfers on the distribution of incomes, labour supply decisions of private households, and their budgetary (fiscal)...

We investigate how personal income taxes affect the portfolio share of personal wealth that entrepreneurs invest in their own business. In a reformulation of the standard portfolio choice model that allows for underreporting of private business income to tax authorities, we show that a fall in...

Social assistance and unemployment assistance, which provide means tested income support (social welfare) without pre-specified time limits, are viewed as one important reason for the persistently high level of unemployment in Germany by many economists. In order to increase work incentives and,...

Germany1, as most other European countries, has been plagued by a persistently high level of long?term unemployment since the early 1980's. In contrast, long? term unemployment is much less of a problem in the United States. One potential reason for the different structure of unemployment...

We analyze the economic factors which have contributed to the dramatic decline of the employment share of unskilled labor in German manufacturing, in particular the role played by the relatively rigid earnings structure. Potential effects of intensified international competition and skill?biased...

At the start of the German unification process it was a commonly held view that east German living conditions will converge to west Geman levels within a few years. This view was not only held by notoriously optimistic politicians but also by a great many of professional economists. With...

We analyze the effectiveness of publicly financed training and retraining programs in east Germany as measured by their effects on individual re-employment probabilities after training. These are estimated by discrete hazard rate models on the basis of individual-level panel data. We account for...

We analyze the dramatic decline of the employment share of unskilled labor in the West German economy, in particular its relation to the relatively rigid earnings structure. We find that the substitution elasticity between unskilled and skilled labor is rather low in most sectors of the economy....

In the paper we simulate a revenue-neutral cut in the social security contribution rate using five different types of macro- / microeconomic models, namely two models based on time-series data where the labour market is modelled basically demand oriented, two models of the class of computable...
