This Paper uses stochastic simulations on calibrated models to assess the steady state impact of different pension arrangements in an environment where financial markets are less than perfect. Surprisingly little is known about the optimal split between funded and unfunded systems when there are...

It is well known that over the next few decades there will be significant changes in the demographic structures of nearly all developed countries; in the absence of massive immigration, or of catastrophic new fatal illnesses, by the middle of the next century the ratio of people of working age...

In this paper we perform simulations with a stylized model of Germany and the United Kingdom to show which generations might be direct gainers, and which losers, from a transition to funded state pensions. We estimate what the structure of inter-generational bequests would need to be in a...
