Cambridge, Ma: Blackwell, Normally, a discount factor is introduced that reduces the present value of future payoffs. This is required order to be able to rank strategies (since the simple sum of every infinite series of positive payoffs is the same). However, because the model that I am developing here has players ‘living’ for only a finite period, I have taken the liberty of dropping the discount factor. Also, it should be noted that the introduction of a discount factor enables one to use a model of the type I am presenting here not only to represent infinitely repeated games, but also finitely repeated games which there is some uncertainty as to when the game will end. Thus the possibility that there may not be an infinite number of future generations need not affect the results of this model. See, e.g. Eric Rasmusen

For further discussion, see Fudenberg and Tirole, 171. It is worth noting that depletionary investment policies are excluded, not because existing generations have some obligation to posterity, but through a simple combination of their self-interest and the assumption that future generations will act rationally. Otherwise put, the elimination of depletionary investment policies is a deductive consequence of the assumption that all individuals maximize expected utility. Because of this, Parfits non-identity problem does not arise. See Derek Parfit, Reasons and Persons (Oxford: Clarendon Press

Furthermore, there is no principle limit on the number of other issues that could be introduced into these negotiations. For instance, each generation could also make its cooperation dependent upon an acceptable population policy. This would resolve the intergenerational PD that Derek Parfit thought would lead to overpopulation. See 383

Thus Sauvé directly begs the question against Gauthier when he claims that: ‘The only cases which new generations will find it irrational to continue the social contract are cases where the benefits of continued cooperation no longer outweigh the benefits available the state of nature’ (168). Gauthiers terms, while broadly compliant agents would reject only depletionary policies, narrowly compliant agents would reject all policies that are unfair (Gauthier, Morals by Agreement, 178). Similarly, Sauvés claim that consumption will ‘ratchet down’ as the social contract is renegotiated across generations, slowing but not stopping resource depletion, is incorrect. Once the cooperative equilibrium is selected, it determines the rational strategy for all players all generations, so there will be no renegotiation

Gauthier. Morals by Agreement 167 Thus Sauvé directly begs the question against Gauthier when he claims that: ‘The only cases in which new generations will find it irrational to continue the social contract are cases where the benefits of continued cooperation no longer outweigh the benefits available in the state of nature’ (168). In Gauthier's terms, while broadly compliant agents would reject only depletionary policies, narrowly compliant agents would reject all policies that are unfair (Gauthier, Morals by Agreement, 178). Similarly, Sauvé's claim that consumption will ‘ratchet down’ as the social contract is renegotiated across generations, slowing but not stopping resource depletion, is incorrect. Once the cooperative equilibrium is selected, it determines the rational strategy for all players in all generations, so there will be no renegotiation.

A more realistic model, in which payoffs may only arise several turns later, gives rise to the possibility of investment policies in which short-term decreases in production can create a greater long-run average.

New York: The Free Press, For discussion see Laurence J. Kotlikoff,. It is worth noting that the current pressure from some members of the ‘baby boom’ generation to defect from the Canada Pension Plan is not a result of their own contribution level being too high. On the contrary, it is because their own contribution level is so low. Their underfunding of the plan amounts to an attempt to effect a massive transfer of wealth from members of younger generations to themselves. However, the scale of this proposed redistribution is so large that many boomers have come to anticipate the defection of these generations. It is this anticipated defection that supplies them with the current motivation to defect from the plan. This would appear to be an example of the ‘unraveling’ that can occur when savings arrangements are adopted that are predictably unacceptable to future generations
