Löhne und gesetzliche Rentenansprüche sind über das Sozialversicherungssystem direkt miteinander verbunden. In dieser Dissertationsschrift werden zunächst Lohnrisiken analysiert, um dann das Altersarmutsrisiko in Deutschland aufzuzeigen. Nach einer Einführung werden in Kapitel 2 die...

We document that home ownership of households with 'heads' aged 25-44 years fell substantially between 1980 and 2000 and recovered only partially during the 2001-2005 housing boom. The 1980-2000 decline in young home ownership occurred as improvements in mortgage opportunities seemingly made it...

This paper assesses the accuracy of decomposing income risk into permanent and transitory components using income and consumption data. We develop a specific approximation to the optimal consumption growth rule and use Monte Carlo evidence to show that this approximation can provide a robust...

Taxation changes the expectations of prospective university students about their future level and uncertainty of after-tax income. To estimate the impact of taxes on university enrollment, we develop and estimate a structural microeconometric model, in which a high-school graduate decides to...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by owner-occupied housing whereas unsecured debt can be discharged according to bankruptcy regulations. We show that the calibrated model matches important quantitative...

Former theoretical and empirical studies find that precautionary savings are reduced inthe presence of social security systems. The saving motive, however, does not change:individuals respond to increasing income risk by increasing their savings. Although thisstill holds for common tax and...

As a new approach we study individual wage compensations due to income risksmeasured by the variance and skewness of the wage distributions in different occupational groups. Using German administrative panel data and estimating a fixed effects model we confirm the expected positive effect of the...

This paper studies empirically the relationship between trade policy and individual income risk faced by workers. The analysis proceeds in three steps. First, longitudinal data on workers are used to estimate time-varying individual income risk parameters in various manufacturing sectors. The...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by durables whereas unsecured debt can be discharged in bankruptcy procedures. We show that the model matches the main quantitative characteristics of observed wealth and debt...
