Much qualitative research has drawn an association between social media and domestic terrorism, with the studies reaching different conclusions. However, few empirical studies have evaluated whether the surge in social media participation affects domestic terrorist events. Controlling for common explanations in the literature, we conduct a cross-national, time-series analysis of up to 151 countries from 2000 to 2019 to assess the impact of social media penetration on domestic terrorism. We find that greater social media penetration increases the likelihood of domestic terrorism in countries as it supports extremists' ability to recruit, mobilize, and train terrorists. Using mediation analysis, we also find that greater social media penetration amplifies online and political polarization, increasing the likelihood of domestic terrorism events. Our work indicates the possible mechanisms linking social media and domestic terrorism and the need to develop and apply appropriate counterterrorism strategies to mitigate terrorist operations.

Conflict research has recently found that increased inequality weakens institutional conditions, opening the door for terrorism. While this research often accounts for endogeneity, or the possibility of a reverse causal relationship, there has yet to be an empirical investigation of the impact of terrorism on income inequality. Using a sample of 139 countries between 1994 and 2018, we show that both domestic and transnational terrorism result in higher levels of income inequality. Our results are consistent for both pre- and post-tax and transfer inequality as well as multiple model specifications. Additionally, we explore multiple potential causal mechanisms that link terrorism and income inequality finding that the effect is, in part, due to terrorism's negative effects on institutional stability, increased military expenditure, possibly to fund counterterrorism operations, and reduced foreign capital, especially for greenfield investment. Our analysis indicates a positive relationship between terrorism and inequality and the mechanisms that produce the effect, contributing to the terrorism and inequality literatures.

This paper studies the effects of foreign direct investment (FDI) on domestic terrorism. Using a cross-national, time-series analysis of 114 countries from 1991–2017, and employing structural equation modeling to test a number of mediating factors, we find that the impact of FDI on domestic terrorism depends on the host state's level of economic development. For host countries at higher-income levels, FDI boosts economic development and global integration promoting prosperity, increasing counterterrorism resources, and reducing the economic grievances that foster terrorism. Conversely, for lower-income host countries, increased FDI fuels higher domestic terrorism, as it intensifies clashes between traditional and modern elements within society, raises economic discrimination, heightens perceptions of economic insecurity, and subsequently leads to grievances directed against the state. Our results indicate a curvilinear relationship between FDI inflows and domestic terrorism, suggesting that FDI produces a double-edged sword between promoting economic development and increasing domestic terrorism in host states.

Since the 1990s, credit rating agencies have played a prominent financial role in developing countries, rating their sovereign bonds and determining capital costs. Over much the same years, domestic terrorism has expanded, increasing market disruptions in countries. Despite the heightened costs related to rebel attacks, few studies investigate the impact of domestic terrorism on bond ratings. Using a sample of seventy-one developing countries between 1996 and 2018, we find that domestic terrorist incidents result in sovereign bond downgrades for countries that receive ratings. Further, when we disaggregate terrorist events by target type, we observe that attacks directed at the government, military and police, business, non-governmental organizations, and private citizens/property have a larger effect than other terrorist incidents. We argue that specific domestic terrorist attacks increase economic instability, leading to capital flight, and a shifting of resources from productive economic sectors to counterterrorism. The resulting economic changes weaken a country's economy and increase debt nonpayment risk. [ABSTRACT FROM AUTHOR]
