Altruistic Foreign Aid and Climate Change Mitigation

Early Access : AUG 2022International audienceThis paper considers one altruistic developed country and several heterogeneous developing countries. We demonstrate that the lack of coordination between countries in tackling climate change finds an optimal solution if developing countries can expect to receive development aid transfers from the developed country. The mechanism requires a sufficiently high level of altruism and specific timing, but a global coalition is not necessary. We also show that the developed country may democratically assign a delegate who is more altruistic than its median voter in order to benefit from the efficiency gain generated by positive development aid transfers
