Terrorism and spatial disparities: Does interregional inequality matter?

This article examines the relationship between interregional inequality and the incidence of domestic terrorism in a panel of 48 countries over the period 1990–2010. The results show that a high level of interregional inequality increases the number of domestic terror events in the sample countries. This finding is robust to the inclusion of additional explanatory variables that may affect both interregional inequality and domestic terrorism. Furthermore, the observed link between interregional inequality and terrorist activity does not depend on the choice of the specific measure used to quantify the degree of dispersion in the regional distribution of GDP per capita within the sample countries.     

The socio-economic determinants of terrorism and political violence in Western Europe (1994–2007)

The main objective of this paper is to empirically investigate the socio-economic causes of terrorism and political violence in a sample of 12 countries in Western Europe. First, we show that in western European countries the classical economic argument of opportunity cost is confirmed. That is, the larger is the set of current economic opportunities for individuals the lower is the likelihood or the willingness for them to be involved in a terrorist activity. Second, expected future economic growth seems to be associated with an increase in current terrorist activities. Eventually, our results also show that terrorist brutality (measured in people killed) is positively associated with real GDP per capita.     

When is Foreign Aid Effective in Fighting Terrorism? Threshold Evidence

Building on the previous literature, we assess when foreign aid is effective in fighting terrorism using quantile regressions on a panel of 78 developing countries for the period 1984–2008. Bilateral, multilateral and total aid indicators are used whereas terrorism includes: domestic, transnational, unclear and total terrorism dynamics. We consistently establish that foreign aid (bilateral, multilateral and total) is effective at fighting terrorism exclusively in countries where existing levels of transnational terrorism are highest. This finding is consistent with our theoretical underpinnings because donors have been documented to allocate more aid towards fighting transnational terrorist activities in recipient countries because they are more likely to target their interests. Moreover, the propensity of donor interest at stake is likely to increase with initial levels of transnational terrorism, such that the effect of foreign aid is most significant in recipient countries with the highest levels of transnational terrorism. Policy implications and future research directions are discussed.     

Inequality and income: The mediating effects of social spending and risk

This paper estimates models of social spending, income risk, and per capita income levels using data from a post-war panel of OECD (Organisation for Economic Cooperation and Development) countries. The objective is to test two theories about the pathway from inequality to per capita income. According to one theory, inequality reduces incomes because it induces social spending, which acts as a drag on the economy. The results here suggest, however, that inequality does not seem to induce social spending, and social spending does not seem to lower per capita incomes. According to a second theory, inequality causes upheaval which adds to the volatility of per capita income, which may reduce the level of per capita income. The results suggest, however, that volatility, measured here as the standard deviation of per capita income, has little measurable impact on either per capita income or social spending. The mainsprings of per capita income are more likely to be the traditional factors: the work force, human capital, and physical capital.

Small investment and large returns: Terrorism, media and the economy

The study investigates the role of the media in the impact of terrorism on the economy. A unique data set of the newspaper articles that reported terrorist attacks during 2002 is used to evaluate their impact on the Tel Aviv Stock Exchange. An econometric analysis is performed in order to understand how a newspaper decides to cover a terrorist attack, i.e. the number of articles, positioning of articles, whether to include photos and the size of headlines. It was found that media coverage is an important channel through which terrorism produces economic damage. The findings also showed that the economic damage caused by terrorist attacks increases monotonically with the amount of media coverage. It was also found that the economic impact of the media coverage diminishes over time.     

Terms of trade volatility,government spending cyclicality,and economic growth

This paper presents estimates of the effects that terms of trade volatility has on real gross domestic product (GDP) per capita growth. Based on 5‐year nonoverlapping panel data comprising 175 countries during 1980 to 2010, the paper finds that terms of trade volatility has significant negative effects on economic growth in countries with procyclical government spending. In countries where government spending is countercyclical, terms of trade volatility has no significant effect on growth. Conditional on the mediating role of government spending cyclicality, the GDP share of domestic credit to the private sector has no significant effect on the relationship between growth and terms of trade volatility.     

Terrorism and the world economy

It has been argued that terrorism should not have a large effect on economic activity, because terrorist attacks destroy only a small fraction of the stock of capital of a country (see, e.g., Becker, G., Murphy, K., 2001. Prosperity will rise out of the ashes. Wall Street Journal October 29, 2001). In contrast, empirical estimates of the consequences of terrorism typically suggest large effects on economic outcomes (see, e.g., Abadie, A., Gardeazabal, J., 2003. The economic cost of conflict: A case study of the Basque country. American Economic Review 93, 113-132). The main theme of this article is that mobility of productive capital in an open economy may account for much of the difference between the direct and the equilibrium impact of terrorism. We use a simple economic model to show that terrorism may have a large impact on the allocation of productive capital across countries, even if it represents a small fraction of the overall economic risk. The model emphasizes that, in addition to increasing uncertainty, terrorism reduces the expected return to investment. As a result, changes in the intensity of terrorism may cause large movements of capital across countries if the world economy is sufficiently open, so international investors are able to diversify other types of country risks. Using a unique data set on terrorism and other country risks, we find that, in accordance with the predictions of the model, higher levels of terrorist risks are associated with lower levels of net foreign direct investment positions, even after controlling for other types of country risks. On average, a standard deviation increase in the terrorist risk is associated with a fall in the net foreign direct investment position of about 5% of GDP. The magnitude of the estimated effect is large, which suggests that the “open-economy channel” impact of terrorism may be substantial.     

Earthquakes and terrorism: The long lasting effect of seismic shocks

The literature on the effect of shocks on civil conflicts has grown rapidly over the last decade. In this paper, we study the relationship between earthquakes and terrorism. In the short run, the destruction generated by a medium-range earthquake reduces the opportunity cost of rebelling against the government. Since destruction of infrastructures in these cases is limited, the state keeps most of its coercive capacity, which reduces the chances of full-fledged conflict but leaves open the possibility of low intensity rebellious acts such as terrorism. In the medium run the destruction of tangible assets can lead to the closing down of weak firms, the introduction of new technologies, the improvement of productivity and the increase in wealth inequality We propose a new algorithm to classify terrorism events as domestic or transnational, and show that the likelihood of a domestic terrorist event increases with the previous occurrence of an earthquake. Using earthquakes as an instrument for income, we also show that development has a positive and significant effect on the likelihood of terrorist events.     

Aid and the Delegated Fight Against Terrorism

A positive empirical relationship is found between the level of foreign aid received by a country and the number of terrorist attacks originating from it. A simple model is used to explain it, where the donor delegates some actions against terrorism to the aid‐recipient government. Aid is endogenous in an econometric equation explaining participation in terrorist events, as expected from the model, and an attacks‐supply curve in which aid has a negative impact is presented at the end.     

Public opinion and terrorist acts

The paper examines support for terrorism in public opinion and the relationship with terrorist attacks. We link the 2007 PEW survey data on justification for suicide terror and opinions in 16 countries of the Middle East, Africa and Asia on nine regional powers, to the NCTC data on international terrorist acts between 2004 and 2008. We find that justification in public opinion for suicide terrorism increases terror attacks on people in countries that are unfavorably regarded. There is a robust positive relationship between the share of the population in a country that at the same time justifies suicide bombings and has an unfavorable opinion of another country, and terrorism originating from the former country.     

Increasing Public Expenditure: Wagner's Law in OECD Countries

Abstract. The paper proposes a panel cointegration analysis of the joint development of government expenditure and economic growth in 23 Organization Economic Cooperation and Development countries. The empirical evidence provides indication of a structural positive correlation between public spending and per‐capita gross domestic product (GDP), which is consistent with the so‐called Wagner's law. A long‐run elasticity larger than 1 suggests a more than proportional increase of government expenditure with respect to economic activity. In addition, according to the spirit of the law, we found that the correlation is usually higher in countries with lower per‐capita GDP, suggesting that the catching‐up period is characterized by a stronger development of government activities with respect to economies in a more advanced state of development.     

Military Spending, Government Disarray, and Economic Growth: A Cross-Country Empirical Analysis

Recent years have seen a spate of empirical studies that have used cross-country regressions to examine a variety of possible determinants of long-term economic growth. The present study considers an additional, largely overlooked, explanatory variable: military spending. Consistent with Thompson’s (1974) hypothesis that enhanced national defense fosters economic growth by increasing the security of property rights, the military expenditures share of GDP is found to have a statistically significant positive impact on the growth rate of per capita GDP. This result is obtained for two alternative model specifications, a Barro-regression and a LISREL variant of that regression. The LISREL variant is motivated by Sala-i-Martin’s (1994) claim that the impact of government economic policies jointly, rather than extant government policies individually and separately, is "the phenomenon that really matters" for long-term economic growth.     

Institutional Quality and Public Debt Accumulation: An Empirical Analysis

The question of public debt management for both developed and developing economies has generated an enormous amount of political as well as academic interest. This study examines how governance affects public debt accumulation in the MENA countries during the 1996–2015 period. The six Worldwide Governance indicators (voice and accountability, political stability and the absence of violence/terrorism, government effectiveness, regulatory quality, rule of law and control of corruption) were used to measure the quality of governance in these countries. The results show that only three governance indicators support well the hypothesis that poor governance leads to higher accumulation of MENA public debt. Moreover, the estimates suggest a significant indirect impact of bad governance operating via decreased GDP growth. These findings have important implications for policy makers of these countries, which are currently facing major fiscal and external imbalances due to the high cost of war and terrorist attacks, low oil prices and a decline in trade. Sound public debt management represents an urgent task especially that public debt management problems often find their origins in the lack of attention paid by policymakers to the costs of bad governance and weak macroeconomic management.     

Islamist terrorism and the status of women

We investigate the effect of Islamist terrorist activity on women's legal position in society, using data for 171 countries between 1970 and 2016. To identify causal effects, we exploit the prevalence of Islamist terrorism in neighboring countries as an exogenous source of variation, arguing that regional terrorism affects local terrorism through contagion effects. We show that increased activity by Islamist terrorist groups is linked to lower legal status of women. By contrast, we find that neither Islam per se nor other types of terrorism have comparable effects. This reinforces the notion that Islamist terrorism is singularly interested and effective in weakening women's rights. Our results are consistent with a rational-economic model of terrorism, where Islamist terrorists purposefully use violence to maximize political utility, while governments make concessions that constrain the role of women because the costs of compliance are lower than the harm from continued Islamist terrorism.     

The effect of government expenditure on the environment:An empirical investigation

This paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980–2000. We estimate both the direct and indirect effects of government spending on pollution. The indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution. To take into account the dynamic nature and the potential endogeneity in the relationships examined, appropriate econometric methods are used. For SO₂, government spending is estimated to have a negative direct impact on per capita emissions, while the direct effect is insignificant on CO₂ pollution. The indirect effect on SO₂ is negative for low income levels and becomes positive as income increases, while it remains negative for CO₂ for the most part of the sample range. The resultant total effects follow the patterns of the indirect effects, which dominate their respective direct ones for each pollutant. Policy implications from the results vary depending on the income level of the considered countries.     

Endogenous mortality, human capital and economic growth

We consider growth and welfare effects of lifetime-uncertainty in an economy with human capital-led endogenous growth. We argue that lifetime uncertainty reduces private incentives to invest in both physical and human capital. Using an overlapping generations framework with finite-lived households we analyze the relevance of government expenditure on health and education to counter such growth-reducing forces. We focus on three different models that differ with respect to the mode of financing of education: (i) both private and public spending, (ii) only public spending, and (iii) only private spending. Results show that models (i) and (iii) outperform model (ii) with respect to long-term growth rates of per capita income, welfare levels and other important macroeconomic indicators. Theoretical predictions of model rankings for these macroeconomic indicators are also supported by observed stylized facts.     

A strategic analysis of the war against transnational terrorism

We study a two stage game in which a transnational terrorist organization interacts with an arbitrary number of countries that may differ in their political or economic power, their military effectiveness, the benefit from cooperating against terrorism and the value they assign to damage. Only a subset of countries that emerges endogenously takes proactive measures to fight the terrorist, while all countries incur defensive expenditures to protect their soil. We characterize analytically the pure strategy subgame perfect equilibrium of the game and show how the equilibrium strategies depend on the key model parameters. We provide an algorithm to find the endogenous set of cooperating countries based on their benefit from cooperation and their political/economic power.     

Short- and long-term relation between economic development and government spending: the role of quality of institutions

ABSTRACT

This paper tests the Wagner’s assumption of the one-sided directional flow moving from economic growth to public spending considering an international database over the 1996–2012 period. By using indicators on the level of country control of corruption, government effectiveness, political stability, rule of law, regulatory quality and voice and accountability, the paper analyses the economic performance-public spending nexus controlling for the quality of the institutions. The empirical evidence supports the existence of the Wagner’s law, showing that, in the short-run, public spending positively reacts to a positive shock in national income, with a lower magnitude for democratic countries. In the long run, the error-correction model shows the convergence between public spending and national output occurring less quickly for non-democratic, low-income and to a smaller extent for non-OECD countries. Institutional quality, such as effort in controlling corruption and the presence of regulations that permit and promote private sector development, may help reducing the amount of per capita public spending and making it more productive. Higher expenses in compositional amenities such as public services for the elderly may explain why public spending per capita will increase the most in economies with a higher share of the population that need healthcare facilities.     

Linkages between inflation,economic growth and terrorism in Pakistan

This paper investigates the linkages between inflation, economic growth and terrorism using annual frequency data over the period of 1971–2010, the maximum time period for which consistent data is available for Pakistan. The ARDL bounds testing approach to cointegration has been applied while robustness of long run relationship is established by using rolling window approach. The empirical evidence confirms the cointegration between inflation, economic growth and terrorism in Pakistan. An increase in inflation raises terrorist attacks while economic growth is also a major contributor to terrorism. Moreover, bidirectional causality is found between inflation and terrorism as investigated by the VECM Granger-causality approach while variance decomposition approach also supports the findings by the VECM Granger causality analysis. Our results therefore points to benefits of pursuing sustainability of low inflation in reducing terrorism. However, it also implies some difficulties for policy-makers in Pakistan in their pursuit for economic growth as latter would result in an increase in terrorism activities crowding out some of the benefits of economic growth.     

Fighting Terrorism: Empirics on Policy Harmonisation

This paper models the feasibility of common policy initiatives against global terrorism, as well as timelines for their enforcement. The empirical evidence is based on 78 developing countries for the period 1984–2008. Domestic, transnational, unclear and total terrorism variables are used. Absolute (or unconditional) and conditional catch‐ups are estimated using Generalised Method of Moments. We establish consistently that, the rate of catch‐up is higher in domestic terrorism relative to transnational terrorism. The time to full catch‐up required for the implementation of common policies without distinction of nationality is found to be in a horizon of 13–20 years for domestic terrorism and 24–28 years for transnational terrorism. Hence, from a projection date of 2009, in spite of decreasing cross‐country differences in terrorists’ attacks, there is still a long way to go before feasible common policy initiatives can be fully implemented without distinction of nationality. The paper is original by its contribution to the empirics of conflict resolution through decreasing cross‐country differences in terrorism tendencies. Policy implications are discussed.
