FORECASTING SERIES CONTAINING OFFSETTING BREAKS: OLD SCHOOL AND NEW SCHOOL METHODS OF FORECASTING TRANSNATIONAL TERRORISM

Transnational terrorism data are difficult to forecast because they contain an unknown number of structural breaks of unknown functional form. The rise of religious fundamentalism, the demise of the Soviet Union, and the rise of al Qaeda have changed the nature of transnational terrorism. ‘Old School’ forecasting methods simply smooth or difference the data. ‘New School’ methods use estimated break dates to control for regime shifts when forecasting. We compare the various forecasting methods using a Monte Carlo study with data containing different types of breaks. The study's results are used to forecast various types of transnational terrorist incidents.     

THE ‘PRICE’ OF TERRORISM

Security measures are said to increase the price of terrorism. This price has not been hitherto defined in an economically meaningful way. This paper provides a precise definition by treating the terrorists’ resource endowment as a parcel of contingent claims to political influence with a price equal to the summed value of those contingent claims in potential states of the world. Equipped with this definition, an equilibrium model of the price of terrorism is deployed. Important insights are gained into the effect of terrorists’ risk aversion at the level of the price of terrorism in different states of the world and the theoretical conclusion is reached that higher security is associated with a lower price of terrorism rather than a higher price. The implications for policy are discussed.     

ANALYSING THE DETERMINANTS OF TERRORISM IN TURKEY USING GEOGRAPHICALLY WEIGHTED REGRESSION

This paper investigates the determinants of provincial terrorism in Turkey taking spatial dimension into account for the time period 1990–2006. Following a traditional global regression analysis, spatial variations in the relationships are examined with geographically weighted regression (GWR) to obtain locally different parameter estimates. Empirical results indicate that increases in income and schooling ratio tend to reduce the provincial average level of terrorism, whereas an increase in unemployment enhances it. Moreover, GWR results indicate that the provincial effects of per capita income and education are more pronounced for the Eastern and South Eastern provinces compared to the Western provinces.     

Economic Performance And Terrorist Activity In Latin America

We investigate the link between economic performance and terrorism for 18 Latin American countries from 1970 to 2007, taking into account the potentially complex nature of this link. Panel causality analysis findings indicate that during this period, terrorism had no causal effect on economic growth. By contrast, we find that growth reduced terrorism in the less developed but not in the higher developed Latin American economies. We argue that group-specific differences (linked to patterns of economic development) govern this causal heterogeneity. From a series of negative binomial regressions we gain additional support for our findings, while also identifying further determinants of terrorism.     

Empirical Investigation into the Determinants of Terrorism: Evidence from Fragile States

Abstract

This study investigates the determinants of terrorism in countries that are in the top category of the Fragile States Index (FSI), and are also prone to terrorism. Panel data for 38 countries mainly from Sub-Saharan Africa, the Middle East and North Africa, and South Asia for the years 2005–2014 are used. Findings from the negative binomial and fixed effects estimation show that fragile state, number of refugees and youth unemployment have positive and significant impacts on terrorism. Military spending is positive but less robust across models. Conversely, FDI and remittances have a negative impact on terrorism with the former less robust. Governance and foreign aid are negative and insignificantly related to terrorism. Policy implications follow from the findings.     

Do migrant remittances react to bouts of terrorism?

This paper examines the short-run behaviour of migrant remittances in the face of terrorism. Using monthly data for post 9/11 terrorist attacks in Pakistan, the study finds evidence of increase in the volume of remittances sent from abroad. This increase is evident in the aggregate, as well as for the three main source regions of North America, the Persian Gulf and Europe. The positive association holds for all the top five migrant-hosting countries of Pakistan. The findings point in favour of an altruistic behaviour of migrant remittances at the macroeconomic level.     

FIGHTING TERRORISM: ARE MILITARY MEASURES EFFECTIVE? EMPIRICAL EVIDENCE FROM TURKEY

The present article aims at investigating the causal relationship between defense spending and terrorism in Turkey using the Autoregressive Distributed Lag (ARDL) bounds testing procedure and Granger‐causality analysis. The findings reveal that there exists a unidirectional causality running form terrorist attacks to defense spending as expected, but not vice versa. In the light of this finding it can be inferred that military anti‐terrorism measures alone are not sufficient to prevent terrorism.     

Growth and Fiscal Consequences of Terrorism in Nigeria

Abstract

In spite of government counter-terrorism expenditure and efforts, the incidence of terrorism in Nigeria appears to be rising. This paper examines the growth and fiscal consequences of terrorism in Nigeria by estimating the terrorism–macroeconomy relation using different measures of terror incidence. The results show that terrorism has an economically and statistically significant negative impact on growth; although this impact is considerably small and short-lived, manifesting only after a lag of about three years. Specifically, the cost of terrorism to Nigeria, in terms of lost GDP per annum, is estimated at 0.82%. Moreover, there is evidence that terrorism leads to the reallocation of economic activity away from private investment spending to government spending; that is, terrorism crowds out investment at a higher rate than its potential to crowd in government spending. Lastly, terrorism alters the composition of government expenditure – with the defence component of government expenditure rising vis-a-vis other expenditure items. The results are robust to allowing for dynamic interactions between terrorism and macroeconomic aggregates.     

Jihad Against Palestinians? The Herostratos Syndrome and the Paradox of Targeting European Jews

Abstract

This paper addresses the waves of mass killings recently perpetrated by individuals with a weak or nonexistent ideological motivation, whose acts either appear to contradict their purported political cause or are admittedly driven by a quest for notoriety. Examples range from killers who have been waging jihad against European Jews to unattached mass killers such as the Germanwings pilot to the perpetrators of mass school shootings in America and worldwide. We argue that these phenomena can be understood as instances of the Herostratos syndrome, which has been known for thousands of years as characterizing the behavior of people who seek to survive in the collective memory by excelling in their infamous acts. We provide a model of hybrid killers which accommodates the Herostratic motive alongside a political motive and characterize a well-behaved Nash equilibrium where Herostratic killers are competing with one another with a view to make a name for themselves in infamy. The policy implications point towards reducing the publicity the killers enjoy, thus frustrating their quest for notoriety.     

A Bioterrorism Prevention Initiative

ABSTRACT

The threat of terrorist use of weapons of mass destruction remains a daunting concern. Governments have undertaken several initiatives at the national and international level to prevent such illicit use, yet challenges remain. Notable is the absence of a single collaborative international forum of experts dedicated solely to bioterrorism prevention. The establishment of a Bioterrorism Prevention Initiative could be a possible solution to address this gap. This article explores possibilities for such an initiative and the ways in which it could strengthen the existing bio-nonproliferation regime.
