The Global Economics of Water: Is Water a Source of Comparative Advantage?
利用新数据研究各国国际贸易如何利用全球不均的水资源，发现水是比较优势的来源，但贡献小于劳动力和资本，暗示气候变化对全球贸易影响有限。
With newly available data, I investigate to what extent countries' international trade exploits the very uneven water resources on a global scale. I find that water is a source of comparative advantage and that relatively water abundant countries export more water-intensive products. Additionally, water contributes significantly less to the pattern of exports than the traditional production factors labor and physical capital. This suggests relatively moderate disruptions to overall trade on a global scale due to changing precipitation in the wake of climate change.
