Risky Business: Political Instability and Sectoral Greenfield Foreign Direct Investment in the Arab World
研究了2003-2012年间中东和北非国家政治不稳定对绿地外国直接投资的影响，发现非资源可贸易部门投资受冲击最大，而自然资源和非贸易部门投资不受影响。
Which foreign direct investments are most affected by political instability? Analysis of quarterly greenfield investment flows into countries in the Middle East and North Africa during the period from 2003 to 2012 shows that adverse political shocks are associated with significantly reduced investment inflows in the non-resource tradable sectors. By contrast, investments in natural resource sectors and non-tradable activities appear insensitive to such shocks. Political instability is thus associated with increased reliance on non-tradables and aggravated resource dependence.
