We analyze the effects of increasing the retirement age in two economies with overlapping generations and within cohort ex ante heterogeneity. The first economy has a defined benefit system, and the second economy is in transition from a defined benefit to a defined contribution. We find that if...

We analyze the political stability of welfare enhancing privatization of the social security. We consider an economy populated by overlapping generations, who vote on abolishing the funded system and replacing it with the pay-as-you-go scheme, i.e. "unprivatizing" the pension system. We show...

Belarus currently has a relatively generous pay-as-you-go pension system, but population aging coupled with recent problems with economic growth will soon make it unsustainable. We build a rich overlapping generation model of Belarusian economy, which shows that without reform the Pension Fund...

We analyze the political stability of capital funded social security. In particular, using a stylized theoretical framework we study the mechanisms behind governments capturing pension assets in order to lower current taxes. This is followed by an analysis of the analogous mechanisms in a...

The present study focuses on certain problems of pay-as-you-go pension systems. In particular, based on reproduction and survival rates, a Leslie type model is used for the analysis of the demographic dynamics of a population. The presented model is different from the classical Leslie model,...

This paper considers the possibility of letting a pay-go pension system mimic a fully funded pension system. Generically, it turns out to be impossible to make a less than fully funded pension system actuarially fair on average. But a non-funded pay-go pension system can provide an actuarially...

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...

This paper focuses on the empirically observed relationship between demographic change and inflation and explores the theoretical nature of the puzzling link between the two. It puts the existent disparate empirical findings in the literature into perspective by formalizing an...
