The design of incentives for participating in an international public good mechanism

全球变暖是我们必须在世界范围内处理的一个重要问题。然而，从美国退出《京都议定书》的事实和最近主要国家在气候变化谈判中持负面态度的例子可以看出，所有国家都很难自愿参与国际环境协议等全球框架。在这项研究中，我们考察了国家之间(本地或全球)谈判和协调对参与行为的作用，并澄清了它们是否可以促使更多的国家自愿参与协议。

The global warming is an important problem which we must treat worldwide. However, as we can see from the fact of the withdrawal of USA from the Kyoto Protocol and a recent example of negative attitudes of major nations in negotiations on climate change, it is quite difficult for all countries to voluntarily participate in global frameworks such as international environmental agreements. In this study, we examine the role of the(local or global) negotiation and coordination among countries on the participation behavior and we clarify whether they can induce more countries to participate in the agreements, voluntarily.
