A unique dataset is used to separately analyze the social origins of left-wing and nationalist-separatist terrorism in 17 Western European countries between 1970 and 2007. We argue that the differences in the historic roots, ultimate goals as well as their negotiability, levels of domestic and...

This contribution investigates the role of education in domestic terrorism for 133 countries between 1984 and 2007. The findings point at a nontrivial effect of education on terrorism. Lower education (primary education) tends to promote terrorism in a cluster of countries where the...

We analyze the effect of income inequality on terrorism for a sample of 114 countries between 1985 and 2012. We provide evidence, robust to various methodological changes (e.g., different dependent variables, instrumental-variable approaches), that higher levels of income inequality are...

We study the effect of large-scale land acquisitions on the risk of ethnic tensions for a sample of 133 countries for the 2000-2012 period. Running a series of fractional response models, we find that more land grabbing activity is associated with a higher risk of ethnic tensions, indicating...

Large-scale land acquisitions often take place in developing countries which are also known for their corruption-friendliness caused by weak institutional frameworks. We hypothesize that corruption indeed leads to more land deals. We argue that corrupt elites exploit poor institutional setups...

In this contribution we study the relationship between income inequality and economic freedom for a panel of 100 countries for the 1971-2010 period. From a panel causality study we find that income inequality has a negative causal effect on economic freedom, while causation does not run in the...

Does U.S. military aid make the United States safer? To answer this question, we collect data on 173 countries between 1968 and 2014. Exploiting quasi-random variation in the global patterns of U.S. military aid, our paper is the first to provide causal estimates of the effect of U.S. military...

We examine the effect of population size on government size for a panel of 130 countries for the period between 1970 and 2014. We show that previous analyses of the nexus between population size and government size are incorrectly specified and fail to consider the influence of cross-sectional...

We investigate the effect of U.S. military aid and U.S. troop deployments on anti-American terrorism, using a sample of 106 countries between 1986 and 2011. We find that greater military commitment leads to more anti-American terrorism. We study the underlying mechanisms using a mediation...

We examine the effect of class cleavages on terrorist activity by anarchist and leftist terrorist groups in 99 American, Asian and European countries over the 1860-1950 period. We find that higher levels of political exclusion of the poor, our main measure of class conflict, were associated with...
