In an analysis of the risk-sharing properties of different types of pension systems, we show that only fixed-fee pay-as-you-go (PAYG) pension systems can provide risk sharing for living individuals. Under some circumstances, however, other PAYG pension systems can enhance the expected welfare of...

It is shown that the net fiscal externality created by an additional member of a pay-as-you-go-pension system that is endowed with individual accounts equals the gross contributions of this member. In Germany, this equals about 175,000 Deutsche marks. The paper uses this information to design 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...

In the face of changes in the demographic and economic situation, governments around the world are reviewing the existing models of pension provision with the prospect of reducing the share of the Pay-As-You-Go system and increasing the share the Fully Funded system. However, the country's...

Old-age income support is becoming an issue of growing importance throughout Asia. This is especially true in East and Southeast Asia where the population is aging. This paper provides a broad overview of the current state of pension systems in the People’s Republic of China, Indonesia,...

The objective of this paper is to analyze the welfare effects of raising the retirement age. With aging populations, in many countries de iure retirement age has been raised. With a standard assumption that individuals prefer leisure to work, such policy necessitates some welfare deterioration....

We evaluate the welfare and macroeconomic effects of increasing the retirement age in the context of population aging. In an overlapping generations framework we simulate the increase of the retirement age by seven years under different pension systems (defined benefit, notionally defined...

The objective of this paper is to inquire the consequences of some simplifying assumptions typically made in the overlapping generations (OLG) models of pension systems and pension system reforms. This literature is largely driven by policy motivations. Consequently, the majority of the papers...

This paper examines the employment effects of a revenue-neutral cut in the social security contribution rate in Germany by running policy simulations in four different types of macroeconomic models. Two models are based on time-series data where the labor market is modeled basically demand...
