This paper employs a large scale overlapping generations (OLG) model with endogenous human capital formation using a Ben-Porath (1967) technology to evaluate the quantitative role of human capital adjustments for the economic consequences of demographic change. We find that endogenous human...

Projected demographic changes in industrialized countries will reduce the share of the workingage population. Analyses based on standard OLG models predict that these changes will increase the capital-labor ratio. Hence, rates of return to capital decrease and wages increase, which has adverse...

In the industrialized world the population is aging over time, reducing the fraction of the population in working age. Consequently labor is expected to be scarce, relative to capital, with an ensuing decline in the real return on capital. This paper uses demographic projections together with a...

Projected demographic changes in industrialized and developing countries vary in extent and timing but will reduce the share of the population in working age everywhere. Conventional wisdom suggests that this will increase capital intensity with falling rates of return to capital and increasing...

We ask whether a PAYG-financed social security system is welfare improving in an economy with idiosyncratic and aggregate risk. We argue that interactions between the two risks are important for this question. One is a direct interaction in the form of a countercyclical variance of idiosyncratic...

This paper modifies standard block Gauss-Seidel iterations used by tatonnement methods for solving large scale deterministic heterogeneous agent models. The composite method between first- and second-order tatonnement methods is shown to considerably improve convergence both in terms of speed as...

The paper examines the long-term implications of various reform options on retirement entry decisions and the actual retirement age of older workers. It focuses on the changes in pension legislation since 1992 and the reform options discussed by the German Social Security Reform Commission...

Die Kontroverse über die „richtigen“ Zu- und Abschläge in der GRV beginnt mit mehreren Begriffsverwirrungen. Dies betrifft vor allem die Begriffe „versicherungsmathematisch fair“, „versicherungsmathematisch neutral“ und „anreizkompatibel“. Nur...

Die Kosten von 36 klassischen Riester-Rentenversicherungen werden anhand von Kostenkennziffern für verschiedene Sparertypen und Verzinsungsannahmen in den unterschiedlichen Phasen der Vertragslaufzeit miteinander verglichen. Es gibt sehr günstige und sehr teure Verträge. Die große...

In the course of the ongoing debate regarding the critique of the German Riester pension the Swedish premium pension has often been referred to as a role model regarding potential amendments and reforms. The Swedish pension reform of 1998 has led to a reorganization towards a stratified scheme,...
