For the design of the pension system, it is crucial to disentangle the employment responses related to the substitution effect and the income effect. In this paper, we provide causal evidence regarding the importance of the income effect, which is generally assumed to be small or non-existent....

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

We estimate a dynamic structural life-cycle model of employment, non-employment and retirement that includes endogenous accumulation of human capital and intertemporal non- separabilities in preferences. Additionally, the model accounts for the effect of the tax and transfer system on work...

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this pressing open question in public finance, we estimate a life-cycle model in which the optimal employment, retirement and consumption decisions of forward-looking...

Estimating labor supply functions using a discrete rather than a continuous specification has become increasingly popular in recent years. On basis of the German Socioeconomic Panel (GSOEP) I test which specification of discrete choice is the appropriate model for estimating labor supply: the...

In the year 2000, the German government passed the most ambitious tax reform in postwar German history aiming at a significant tax relief for households. Drawing on data of the GSOEP, we analyze the distributional and fiscal effects of the tax reform. Our analysis employs microsimulation...

In the year 2000, the German government passed the most ambitious tax reform in postwar German history aiming at a significant tax relief for households. An important aim of this tax reform was to improve work incentives and, thereby, foster employment. Drawing on data of the German Socio...

We analyze empirically the optimal mix and optimal generosity of social insurance and assistance programs. 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...

This paper shows that labor demand plays an important role in the labor market reactions of older women affected by pension deductions for early retirement. Based on a large representative sample of the German workforce (SIAB), we calculate the consequences of individual financial incentive...
