We performed a cross-sectional, bottom-up observational study of resource consumption and quality of life of patients with multiple sclerosis (MS) in Germany. Six centers participated in the study. Patients were asked to complete a questionnaire, and a total of 737 patients returned the...

We performed a cross-sectional, bottom-up observational study of resource consumption and quality of life of patients with multiple sclerosis (MS) in the United Kingdom. Three centers participated in the study. Patients received a questionnaire either by mail or during a clinic visit, and a...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...

In this paper, I estimate the fiscal impact of immigrants on the German pension insurance (PI) and unemployment insurance (UI) systems when return migration is an endogenous choice. For this purpose, I develop a dynamic stochastic model of joint return migration and saving decisions that...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

We state efficiency conditions for the provision of congestable local public goods that diminish individual-specific proprietary risks. The optimum level of such a public service is determined by equating the sum of the reductions of the expected property losses due to a better service level...

This paper investigates the sustainability of the German economy when reaching the Kyoto emissions reduction target. We use a special intergenerational discounting technique which actually takes into account intergenerational peculiarities in an overlapping generations modeling framework which...

Within this paper, we analyse the fulfilment of the Kyoto-emissions reduction com-mitment exemplary in Germany and its implication on long-term paths of all macro-variables. Germany, like all other industrial or Annex B coun-tries, has to reduce its emissions by 2010 and after what we call a...

We extend "economic equivalence" results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are "politico-economically...

Die deutsche Bevölkerung durchläuft in den nächsten Jahrzehnten einen demographischen Alterungsprozess, der als erstes die Erwerbsbevölkerung erfasst. Dieser Beitrag diskutiert die ökonomischen Folgen dieser Entwicklung. Direkte Arbeitsmarkteffekte einer schrumpfenden und alternden...
