I compare the relative importance of intergenerational altruism and contemporaneous cooperation, in determining equilibrium climate policy, by imbedding an OLG framework with intergenerational altruism into a differential game between nations. The model uses new representations for the aggregate preferences of OLGs with paternalistic or pure altruism, and exponentially distributed or deterministic lifetimes. In a linear-in-state model of climate change, the "limit equilibrium" is more sensitive to contemporaneous cooperation than to intergenerational altruism. This comparison also holds in other Markov perfect equilibria if one uses a particular "elasticity criterion", but can be overturned under a more subjective criterion of relative sensitivity.
