In recent decades, many states have reduced future retirement benefits for newly hired teachers. We estimate that in 2020 the average initial monthly retirement benefit, for teachers retiring with 30 years of service, is 11.2 percent lower than that of teachers retiring in the same plan with the...

This paper explores the introduction of collective risk-sharing elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset contingent risk-sharing arrangements. All arrangements raise aggregate welfare, as measured by equivalent variations. While...

Intergenerational risk sharing by funded pension schemes may increase welfare in an ex ante sense. However, it also suffers from a time inconsistency problem. In particular, young generations may be unwilling to start participating in a pension scheme if this requires them to make huge transfers...

We analyze a collective defined contribution pension fund which aims at intergenerational risk sharing among different age cohorts using a return smoothing mechanism. Using a utility based framework, we find that approximately one third of unexpected return shocks should be directly passed on to...

This paper explores the effect of letting individuals choose their retirement age in a world of uncertainty where there exist both defined benefit (DB) and defined contribution (DC) pension plans. The paper shows that giving individuals the flexibility to determine when to retire is an important...

This paper examines policies for the decumulation of pension wealth in the Netherlands. It suggests a design framework based on economic theory and international evidence. The central message is that a well-designed pension system has an important – although certainly not exclusive – role...

This paper develops an analytical framework for the design of pension systems, taking the functions of the pension system as the guiding principle. It discusses the economic principles underlying these functions and their implementation in practice. In particular, it distinguishes three...

This paper takes stock of the evolution in pension systems and the challenges that remain for the future. It derives a typology of pension systems and uses this to discuss the strengths and weaknesses of alternative systems. After describing how pension systems in the industrial world have been...
