Domestic versus transnational terrorism: Data, decomposition, and dynamics

TLDR
In this article, a method to separate the Global Terrorism Database (GTD) into transnational and domestic terrorist incidents was proposed, which is essential for the understanding of some terrorism phenomena when the two types of terrorism are hypothesized to have different impacts.
Abstract
This article devises a method to separate the Global Terrorism Database (GTD) into transnational and domestic terrorist incidents. This decomposition is essential for the understanding of some terrorism phenomena when the two types of terrorism are hypothesized to have different impacts. For example, transnational terrorism may have a greater adverse effect than domestic terrorism on economic growth. Moreover, the causes of the two types of terrorism may differ. Once the data are separated, we apply a calibration method to address some issues with GTD data - namely, the missing data for 1993 and different coding procedures used before 1998. In particular, we calibrate the GTD transnational terrorist incidents to ITERATE transnational terrorist incidents to address GTD's undercounting of incidents in much of the 1970s and its overcounting of incidents in much of the 1990s. Given our assumption that analogous errors characterize domestic terrorist events in GTD, we apply the same calibrations to adjust GTD domestic incidents. The second part of the article investigates the dynamic aspects of GTD domestic and transnational terrorist incidents, based on the calibrated data. Contemporaneous and lagged cross-correlations for the two types of terrorist incidents are computed for component time series involving casualties, deaths, assassinations, bombings, and armed attacks. We find a large cross-correlation between domestic and transnational terrorist incidents that persists over a number of periods. A key finding is that shocks to domestic terrorism result in persistent effects on transnational terrorism; however, the reverse is not true. This finding suggests that domestic terrorism can spill over to transnational terrorism, so that prime-target countries cannot ignore domestic terrorism abroad and may need to assist in curbing this homegrown terrorism.

National Consortium for the Study of Terrorism and Responses to Terrorism

Abstract: 1 July 7, 2010, marks the fifth anniversary of the 2005 terrorist attacks on London’s Metro system. In 2005, terrorists launched a coordinated attack against London’s transportation system, with 3 bombs detonating simultaneously at three different Metro stations and a fourth bomb exploding an hour later on a city bus. In all, there were 52 victims in these bombings with an additional 700 injuries resulting. The four terrorists who executed the attacks were killed in the explosions.

Inequality, Grievances, and Civil War

TL;DR: Cederman et al. as mentioned in this paper argue that political and economic inequalities following group lines generate grievances that in turn can motivate civil war, and develop new indicators of political exclusion at the group level, and show that these exert strong effects on the risk of civil war.

Poverty, minority economic discrimination, and domestic terrorism

TL;DR: In this paper, the authors revisited the relationship between poverty and terrorism and suggested a new factor to explain patterns of domestic terrorism: minority economic discrimination, and found that countries featuring minority group economic discrimination are significantly more likely to experience domestic terrorist attacks.

Lock, stock, and barrel: a comprehensive assessment of the determinants of terror

TL;DR: In this article, the authors assess the robustness of previous findings on the determinants of terrorism using extreme bound analysis, the three most comprehensive terrorism datasets, and focusing on the three commonly analyzed aspects of terrorist activity, i.e., location, victim, and perpetrator.

Foreign direct investment, aid, and terrorism

TL;DR: This paper investigated the relationship between the two major forms of terrorism and foreign direct investment (FDI) and found that when aid is subdivided, bilateral aid is effective in reducing the adverse effects of transnational terrorism on FDI, whereas multilateral aid is more robust in ameliorating the adverse effect of domestic terrorism.

The Political Economy of Terrorism

TL;DR: The Political Economy of Terrorism as mentioned in this paper presents a widely accessible political economy approach to the study of terrorism, which applies economic methodology combined with political analysis and reality to study domestic and transnational terrorism.

The Macroeconomic Consequences of Terrorism

TL;DR: This paper performed an empirical investigation of the macroeconomic consequences of international terrorism and interactions with alternative forms of collective violence and found that on average, the incidence of terrorism may have an economically significant negative effect on growth, albeit one that is considerably smaller and less persistent than that associated with either external wars or internal conflict.

Is Transnational Terrorism Becoming More Threatening? A Time-Series Investigation

TL;DR: In this paper, the authors apply time-series techniques to investigate the current threat posed by transnational terrorist incidents, and investigate three alternative casualties series (incidents with injuries and/or deaths, the proportion of incidents with casualties, and incidents with deaths).
