The stock market collapse led to political tensions between generations due to the fuzzy definition of the property rights over the pension funds’ wealth. The problem is best resolved by the introduction of generational accounts. Modern consumption and portfolio theory shows that the younger...

This paper investigates the international spillovers of government debt and the associated risk of inflation within a monetary union when countries have different pension systems. I use a stochastic two-country two-period overlapping-generations model, where one country has PAYG pensions and the...

Contemporary financial stochastic programs typically involve a trade-offbetween return and (downside)-risk. Using stochastic programming we characterize analytically (rather than numerically) the optimal decisions that follow from characteristic single-stage and multi-stage versions of such...

Recent research reveals that hedge fund returns exhibit a range of different,possibly non-linear pay-off patterns. It is difficult to qualify all these patternssimultaneously as being rational in a traditional framework for optimal financial decisionmaking. In this paper we present a simple...

Regulators often set value-at-risk (VaR) constraints to limit the portfolio risk of institutional investors. For some investors, notably pension funds, the VaR constraint is enforced over a horizon which is significantly shorter than the investment horizon of the investor. Our paper aims to...

We estimate the impact of health and financial incentives on the retirement transitions of older workers in Spain. Individual measures of pension wealth, peak and accrual values are constructed using labor market histories and health shocks are derived as changes in a composite health stock...

This discussion paper led to a publication in <A href="http://www.springerlink.com/index/J107501580204223.pdf">'De Economist'</A>, 159(3), 323-360.<p>We investigate numerically how indexation of funded pensions for inflation can be differ-entiated across the various groups of fund participants. The pension arrangement is modelledafter the Dutch situation. While the...</p></a>

The paper addresses two related issues: the optimal intergenerational sharing of laborproductivity risks, through a Pay-As-You-Go (PAYG) social security, and the mix ofPAYG and savings for retirement provision in a small open economy. It shows that <I>partial</I> contingency of the social security on...</i>

We explore the feasibility of a funded pension system with intergenerational risk sharing when participation in the system is voluntary. Typically, the willingness of the young to participate depends on their belief about the future young's willingness to do so. We characterise equilibria with...

We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The bene􀏐it of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system...
