Foreign Direct Investment in Mexico since the Approval of NAFTA
使用跨国面板数据评估自由贸易协定对外国直接投资流量的影响，发现协定对较小成员国（如墨西哥）的FDI流入有显著正向效应，NAFTA使墨西哥FDI流量比无协定情况下高出近60%。
Cross-country panel data are used to assess the effect of free-trade agreements on flows of foreign direct investment (FDI). Free-trade agreements are found to have a significant positive effect on FDI flows, and free-trade agreements are found to matter more for the smaller members of the agreement. For example, the North American Free-Trade Agreement’s (NAFTA) effect on FDI flows into Mexico is much larger than its effect on flows into the United States. These cross-country results are used to assess NAFTA’s effect on FDI flows into Mexico. After controlling for a set of other factors--such as an increase in worldwide FDI flows--the trade agreement is found to generate FDI flows nearly 60 percent higher than they would have been without the agreement.
