It relates the threat posed by terrorist attacks to how capable a terrorist group is to carry out attacks. As such, it links the threat not to the willingness of a terrorist group to conduct attacks but to its ability to do so. I maintain that for any active terrorist group the willingness to commit attacks is a necessary requirement. A terrorist group’s capability, in contrast, depends on a variety of internal and external factors. Study- ing how differences in those endowments or constraints induce varying capabilities offers a tangible approach to understand the threat posed by a specific terrorist group. I argue that in order to conduct attacks, a terrorist group needs resources. This dissertation discusses different aspects of how terrorist groups generate resources. Access to resources and a terrorist group’s ability to manage resources helps to explain variation in the behavior of terrorist groups. To develop my argument I focus on the economic activities of a terrorist group, claiming that a terrorist group, just like a firm, needs to efficiently exploit its opportunities. With this argument I turn the attention to the economic activities of a terrorist group in preparation of the attack and away from the attack itself. I argue that terrorist groups acquire resources from interacting with their environment. The resource allocation is affected by the organizational structure as it determines whether a terrorist group can manage its resources efficiently. Thus, I highlight two steps of the resourcing process. One step focuses on the environment of terrorist groups and another highlights group-internal processes. I argue that both steps act independently from each other and interdependently. I put my argument to three empirical tests analyzing the behavior of terrorist groups as a result of external environmental conditions and group-internal factors. First, I investigate why terrorist groups adopt either a centralized or a decentralized structure depending on environemental and group-internal conditions. Second, I assess to what degree external and internal factors can accurately predict a terrorist group’s involvement in organized crime. Finally, I analyze the effect of a terrorist group’s social capital and managerial capacity on its operational capability individually and jointly. The clandestine nature of terrorist groups introduces non-trivial challenges in terms of data collec- tion. In order to carry out large-n cross-sectional analyses on a global scale, I utilize a variety of existing data sourced from published data by other terrorism researchers. I enrich this collection of data by cod- ing original data. The organizational structure and a terrorist group’s involvement in organized crime are manually coded using publicly accessible information. The type of weapon a terrorist group uses in its attack approximates the operational capability of a terrorist group. The social capital of terrorist groups is operationalized with the position of a terrorist group within the cooperation network of 205 terrorist groups. To that end, I create a network of cooperating terrorist groups and calculate network measures to assess a terrorist group’s access to social capital. Chapter 1 motivates the research question addressed in this dissertation and discusses central theor- etical and empirical contributions. Chapter 2 reflects the relevant literature as a foundation to understand terrorist groups as economic entities that can be affected by market conditions and managerial capacit- ies. In chapter 3, I develop the theoretical argument. Chapter 4 is the first empirical chapter. In line with my argument, I find that the environment affects the likelihood of a terrorist group to adopt a cent- ralized organizational structure. Additionally, I find ideology to have an effect as well, illustrating that both external and internal factors affect which organizational design a terrorist group adopts. In chapter 5, I utilize an inductive machine learning approach using a random forest classifier to test previously discussed environmental and organizational determinants of a terrorist group’s involvement in organ- ized crime. I find that organizational variables out-perform environmental ones in terms of predictive capacity. Group size and ideology are the most influential variables for leveraging accurate predictions. iv In chapter 6, I analyze the influence of a terrorist group’s social capital and managerial capacities to efficiently allocate resources by assessing the effect of a terrorist group’s network position and its organ- izational structure on the operational capability. I provide evidence for an independent impact and an effect of a terrorist groups network position moderated by its organizational structure. I find that terrorist groups benefit from cooperating with terrorist groups that are well connected themselves. My research shows that in order to analyze the economic activities of a terrorist group external and internal factors cannot be separated. Group-internal dynamics condition a terrorist group’s external activities. The ideology and size of a terrorist group predict its involvement in organized crime. The organizational structure influences the operational output of a terrorist group by mitigating the effect of social capital. The organizational structure itself is also affected by a terrorist group’s ideology, repressive conditions in the state it operates in, and societal conditions a terrorist group needs to address in order to mobilize sustained support. The findings of this dissertation have important policy implications. By turning the attention to the economic activities of a terrorist group, this dissertation offers crucial and actionable insights for counter-terrorism researchers and practitioners. By focusing on the resourcing of terrorist groups we learn more about what a group is actually able to do. This approach disentangles the willingness of a terrorist group to commit terrorist attacks from its actual prowess. As counter-terrorism strategies that focus on undermining and destroying the ideology of terrorist groups are failing, tailoring a strategy to cut the supply of resources might be more promising to manage the terrorist threat. v Contents List of Tables ix List of Figures xi 1 Introduction 1 1.1 Motivation and research question . .1 1.2 Main theoretical argument . .3 1.3 Empirical approach . .4 1.4 Plan of the dissertation . .5 1.5 Central contributions . .6 1.5.1 Theoretical and conceptual contributions . .6 1.5.2 Empirical and methodological contributions . .7 2 Terrorism in the broader context 9 2.1 Terrorism as a political strategy . .9 2.2 Rationality of terrorism . 12 2.3 Terrorism – a definitional debate . 14 2.3.1 A working definition of terrorism . 17 2.3.2 Terrorist groups as economic entities . 19 2.4 A market model of terrorism . 22 2.4.1 The economic market of terrorism: The behavior of terrorist groups as a function of resources . 25 2.4.2 The challenges to cooperation between terrorist groups . 29 2.5 Organizational structure in terrorism research . 32 3 The economic market of terrorism – a theory of resource acquisition and resource alloca- tion 37 3.1 Terrorist groups as organizations . 38 3.2 The performance of terrorist groups as a function of resources . 40 3.2.1 Conceptualizing the performance of terrorist groups . 41 3.2.2 Previous definitions of resources . 44 3.2.3 The tradability of resources – an original conceptualization . 47 3.3 The acquisition of resources . 55 3.3.1 Terrorist groups in their resource environment . 55 3.3.2 Relational rents . 57 3.4 The allocation of resources . 60 3.4.1 Previous conceptualizations of organizational structure . 60 3.4.2 Conceptualizing the organizational structure by the degree of centralization . 62 3.5 Summary . 70 vi 4 The environmental effect on the organizational structure of terrorist groups 73 4.1 Introduction . 73 4.2 Organizations as sticky institutions . 76 4.3 Which structure to adopt? . 77 4.3.1 Case examples . 79 4.4 Environmental explanation of organizational structure . 81 4.4.1 Alternative explanations . 85 4.5 Research design . 87 4.5.1 Data and operationalization . 87 4.5.2 Dependent variable: Organizational structure - centralization . 89 4.5.3 Independent variables . 90 4.5.4 Handling missing data problems . 92 4.5.5 Method . 93 4.6 Results . 93 4.7 Conclusion . 100 5 Exploring the determinants of terrorist involvement in organized crime1 103 5.1 Introduction . 103 5.2 Terrorism and organized crime . 105 5.2.1 Comparison of terrorist groups and organized crime . 106 5.2.2 Collaboration and appropriation . 107 5.3 Terrorist groups’ involvement in organized crime . 107 5.4 Predictors of terrorist group’s engagement in organized crime . 109 5.4.1 Organization-level characteristics . 110 5.4.2 Environment-level characteristics . 113 5.5 Research design . 116 5.5.1 Unit of analysis and scope conditions . 116 5.5.2 Variables and operationalization . 116 5.5.3 Statistical methodology . 119 5.6 Results . 120 5.7 Conclusion . 123 6 The network effect on the capability of terrorist groups2 127 6.1 Introduction . 127 6.2 The social capital of terrorist groups – a network perspective . 130 6.2.1 Direct connections to other terrorist groups . 132 6.2.2 Embeddedness within the network . 133 6.2.3 Access to structural holes . 134 6.3 Organizational structure and operational capability .
