The Nonlinear Relationship between Terrorism and Poverty
研究发现贫困对国内恐怖主义有很强的影响，对跨国恐怖主义影响较小但显著，且这种关系是非线性的。
In spite of the common wisdom that poverty breeds terrorism, econometric tests usually find that terrorism is influenced by population and various measures of democratic freedom, but not per capita GDP. Unlike previous studies, we use a data set containing separate measures of domestic and transnational terrorism and estimate models allowing for a nonlinear relationship between terrorism and poverty. When we account for the nonlinearities in the data and distinguish between the two types of terrorist events, we find that poverty has as a very strong influence on domestic terrorism and a small, but significant, effect on transnational terrorism.
