We examine optimal taxation and social insurance if insurance markets are imperfect. This requires the development of a theory of labor supply under uncertainty. We show that the case for social insurance is not generally reinforced by adverse selection in insurance markets as social insurance will have welfare-decreasing effects on the labor market. Furthermore, positive and normative implications ...
Abstract: We analyse benefit-entitlement effects and the likely impact of the recent reform of the unemployment compensation system on the duration of unemployment in Germany on the basis of a flexible discrete-time hazard rate model estimated on pre-reform data from the German Socioeconomic Panel (SOEP). We find (i) relatively strong benefit-entitlement effects for the unemployed who are eligible ...
Generous income support programs as provided by European welfare states have often been blamed to hamper employment. This paper investigates the importance of incentives inherent in the tax-benefit system for the individual decision to take up work. Using German microdata over the period 1993-2010 we find that recent reforms in Germany increased work incentives at the extensive margin measured by the ...
We analyze empirically the optimal design of social insurance and assistance programs when families obtain insurance by making labor supply choices for both spouses. For this purpose, we specify a structural life-cycle model of the labor supply and savings decisions of singles and married couples. Partial insurance against wage and employment shocks is provided by social programs, savings and the labor ...
Informal care by close family members is the main pillar of most longterm care systems. However, due to demographic ageing the need for long-term care is expected to increase while the informal care potential is expected to decline. From a budgetary perspective, informal care is often viewed as a cost-saving alternative to subsidized formal care. This view, however neglects that many family carers ...
We demonstrate that interpersonal comparisons lead to "keeping up with the Joneses"-behavior. Using annual household data from the German Socio-Economic Panel, we estimate the causal effect of changes in reference consumption, defined as the consumption level of all households who are perceived to be richer, on household savings and consumption. When controlling for own income, an increase in reference ...
