This paper examines the quantitative effects of the transitional system of value-added taxation for intra-EC trade after 1992, as recently adopted by the ECOFIN-Council. First, the administration of the current destination principle and the interim solution are described and a mathematical...

The present paper aims to quantify efficiency properties of flat and earnings-related pay-as-you-go financed social security systems of various institutional designs in order to identify an optimal pension design. Starting from a benchmark economy without social security, we introduce...

Nach Meinung von Hans Fehr, Lehrstuhl für Finanzwissenschaft, Universität Würzburg, belastet der aktuelle Gesetzentwurf zur Reform der Rentenversicherung pauschal die Beitragszahler, konterkariert die eingeleitete Anhebung des Rentenzugangsalters und hilft nur wenig gegen die künftig...

The present paper quantifies the economic consequences of eliminating the system of income splitting in Germany. We apply a dynamic simulation model with overlapping generations where single and married agents have to decide on labor supply and homework facing income and lifespan risk. The...

The present paper quantifies the importance of family structures for the analysis of social security. For this reason we introduce home production as well as stable and unstable families into the standard stochastic overlapping generation model and simulate with each model version a move from...

We simulate corporate tax reform in a single good, five-region (U.S., Europe, Japan, China, India) model, featuring skilled and unskilled labor, detailed region-specific demographics and fiscal policies. Eliminating the model's U.S. corporate income tax produces rapid and dramatic increases in...

The present paper aims to quantify efficiency properties of real world social security systems of various institutional designs in order to identify an optimal pension design. Starting from a benchmark economy without social security, we introduce alternative pension systems and compare the...

Recent reforms that aim at reducing the upcoming burdens of population ageing might seriously harm low income individuals. An increase in old-age poverty and disability will be the result. Under this prospect, the present paper quantitatively characterizes the optimal progressivity of unfunded...

The present paper quantifies the economic consequences of eliminating the system of income splitting in Germany. We apply a dynamic simulation model with overlapping generations where single and married agents decide on labor supply and homework under income and life-span risk. We compute...
