Immigration policy and counterterrorism
研究发展中国家恐怖分子如何分配资本和劳动力于国内外目标，分析外国移民配额对恐怖袭击组合的影响，发现提高技术劳工配额通常能减少外国遭受的袭击。
In a developing country, terrorists recruit and allocate their capital, skilled labor, and unskilled labor between domestic and foreign targets. Domestic targets require less skilled labor than foreign targets. Under various strategic scenarios, we show how countermeasures against the different terrorist inputs alter the amount and mix of targets, as well as how skilled and unskilled immigration quotas by a targeted foreign country affect this mix of attacks. We find that increases in skilled labor quotas generally reduce terrorist attacks in the foreign country, especially when the terrorists reside in a skill-scarce country. A number of different strategic scenarios, including leader–follower, are investigated.
