The currently observed demographic change consists of two independent developments that differ in structure and persistence: (1) A slow, monotonic and (presumably) permanent ageing effect caused by an increasing life expectancy; (2) a more rapidly changing, non-monotonic and less permanent...

This paper explores the introduction of collective risk-reallocation elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset-contingent arrangements to reallocate risk among participants. Eliminating asset market risk for the retired raises...

We analyze the political stability of funded social security. Using a stylized theoretical framework we study the mechanisms behind governments capturing social security assets in order to lower current taxes. The results and the driving mechanisms carry over to a fully-fledged and carefully...

This paper addresses the questions of what is an economically efficient pension system, what are the externalities and what are the risks of the four alternative pension systems: financial defined contribution (FDC), notional or non-financial defined contribution (NDC), financial defined benefit...

In this paper we model an OLG-economy where labour supply is endogenously determined and where we assume that there are two pension systems, namely, a pay-as-you-go system and a funded system. The main question is whether there is an equilibrium involving an old-age pensions system, partly...

Feldstein [1985] posed the questions of what would be the optimal level of retirement benefit, and what would be the optimal mix between the pay-as-you-go system and the funded pension system under the assumption of an exogenous interest rate. We reconsider the problem with the addition of a...

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 purpose of this study is to explore the effects of exogenous social security system parameters on welfare. The set up is an overlapping generations economy, with skills heterogeneity, which distinguishes consumers between high and low skilled. The lowskilled receive an extra supplement...

Nonfinancial defined contribution (NDC) pension schemes have been successfully implemented since the mid-1990s in a number of European countries such as Italy, Latvia, Norway, Poland, and Sweden. The NDC approach features the lifelong contribution-benefit link of a financial defined contribution...

This paper develops a social insurance accounting model for a notional defined contribution (NDC) scheme combining retirement and long-term care (LTC) contingencies. The procedure relies on standard double-entry bookkeeping and enables us to compile a “Swedish” type actuarial balance sheet...
