Revealed Preferences of an International Trade and Environment Institution
通过分析北美自由贸易协定机构对美墨边境环境项目的审批数据，发现该机构偏好解决跨境废水污染和遵循污染者付费原则的项目，不偏好创收或成本最小化的项目，且美方项目获批更多。
<i>International cooperation on environmental problems is examined through the factors influencing a North American Free Trade Agreement (NAFTA) institution’s decisions over environmental problems along the U.S.-Mexico border. An econometric study relates the approval by the NAFTA institution of environmental improvement projects to observed attributes of the proposed projects. Results show strong preference for projects solving trans-boundary wastewater pollution and the polluter pays principle. The institution does not prefer projects that generate revenues nor minimize costs. Bi-national grants and loans dominate the funding for approved projects, implying both countries pay. More U.S. projects have been approved than projects from Mexico.</i>
