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...

If private sector agents hold rational expectations, they will predict any future policy switches. Discounting the announced optimal policies, if they are not credible, will lead to a response which deprives the government of any incentive to renege on previous announcements and of the benefits...

A classical equilibrium model is analysed of two interdependent monetary economies in which it is assumed that cash is the only asset, and which is characterized by perfect foresight, flexible exchange rates and imperfect substitution between home and foreign goods. The first-best optimum sets...

This paper examines the implications for strategic trade policy of different assumptions about precommitment. In a dynamic oligopoly game with learning by doing, the optimal first-period subsidy is lower if firms cannot precommit to future output than if they can; and is lower still if the...
