Altruistic Foreign Aid and Climate Change Mitigation
研究了一个利他的发达国家与多个异质发展中国家之间的互动，发现若发展中国家预期能获得发展援助，则无需全球联盟即可最优解决气候变化协调问题。
Abstract This 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.
