1) "Is There a Rebel Resource Curse? Reevaluating the Conventional Wisdom" Invited to Revise and Resubmit. Draft Available Here.

Abstract: How do recruitment tactics affect the success of rebel groups in civil wars? To what extent do material resources “curse” rebels? The conventional wisdom holds that recruitment strategies that rely more on ideological appeals, relative to material incentives, attract more committed recruits who are more invested in the success of their groups than their materially motivated counterparts.  However, I argue that highly committed recruits provide rebel organizations with a double-edged sword. While ideological appeals help attract committed recruits, the most devoted militants also often introduce a variety of problems into the bargaining process, which undermine the ability of rebels to earn negotiated settlements. Furthermore, ideological-based recruitment strategies often fail to attract sufficiently powerful fighting forces, making it difficult for rebels to achieve outright victory. Thus, contrary to the conventional wisdom, I expect that ideologically based recruitment strategies do not help rebels achieve long-term success. To test this claim, I employ novel data on the recruitment practices of rebel organizations that were active across the world between 1989 and 2011. Departing from existing literature, I do not find evidence that greater reliance on ideological recruitment appeals, relative to material incentives, increases or decreases the probability that rebel organizations achieve favorable outcomes.

 

2)"Unhappy Campers in a Big Tent: Rebels’ Use of Diverse Recruitment Appeals and the Intractability of Civil Conflicts" Under Review. Draft Available Here.

Abstract: Do rebel groups benefit from attempting to appeal to larger segments of society by mobilizing around more diverse grievances? Prior work has examined a variety of dimensions of grievance-based recruitment in civil wars but has tended to overlook the ways in which the breadth of recruitment appeals made by rebels matters. I argue that rebel organizations actually suffer from attempts to appeal to a diversity of grievances. Specifically, when rebel organizations represent a diversity of interests, a variety of bargaining issues are exacerbated, including credible commitment problems, information asymmetries, and issue indivisibilities, rendering conflicts more intractable. Using novel data on the diversity of grievance-based recruitment appeals employed by armed groups, I find support for my argument that conflicts are less likely to resolve when rebels mobilize around a greater number of grievances.

3) Soules, Michael J. and Christopher Willis: "Rebel Recruitment Tactics and Repertoires of Violence." Under Review. Draft Available Here.

Abstract: The conventional wisdom is that militant organizations that rely more on ideological appeals, relative to material incentives, for recruitment, will be more restrained in their treatment of civilians on a variety of dimensions. However, in this paper, we argue that greater reliance on ideological appeals will be associated with restraint in the use of some forms of violence, but not others. We expect that because of normative commitments, institutional constraints, and internal cohesion, ideologically driven rebels will be less likely to engage in sexual violence. However, for the same reasons, we also expect that ideologically committed recruits are often motivated to perpetrate other forms of lethal and non-lethal, non-sexual violence. As a result, ideologically motivated recruits will be more likely to employ repertories of violence that show restraint in the use of sexual violence, but not other forms of abuse. Using novel data on the recruitment practices of rebel groups across the world, we find evidence for our argument.

4) "Rebel Recruitment and Governance: How Mobilization Strategies Shape Rebels’ Provision of Social Services." Under Review. Draft Available Here.

Abstract: How do rebel groups’ recruitment strategies shape their provision of social services to civilians? I argue that when groups rely exclusively on material incentives or fully on ideological appeals for recruitment, they are unlikely to provide civilians with services such as healthcare and education. Primarily materially driven groups avoid providing social services because they undermine profits and they lack the ideological foundations and internal cohesion that often promote the offering of these public goods. In contrast, groups that recruit heavily with ideological appeals lack the material resources to provide these services. However, rebels that recruit with a combination of ideological and material appeals have the ideological drive to provide public goods and the material resources required to provide them. Using data on rebel recruitment tactics and social services provision, I find consistent evidence that groups that employ both ideological and material recruitment appeals are more likely to provide social services to civilians than organizations that use just one type of recruitment appeal.

1) "Women’s Status and the Sex Gap in Support for Political Violence."  Draft Available Here.

Abstract: An extensive body of literature investigates the sex gap in support for political violence, examining why women, on average, are less supportive of political violence than men. One strand of research posits that higher levels of societal sex equality will reduce the gap in support for political violence between women and men. However, other scholarship discusses how men sometimes become more supportive of political violence to curtail increasing women’s empowerment. Thus, the effects of sex equality on the sex gap in support for political violence are disputed. To assess these competing hypotheses, I employ data from the World Values Survey to examine how the interaction of individuals’ sex and the levels of sex equality in the countries in which they reside affect their support for political violence. I find that the gap in support for political violence between women and men widens as women’s overall status in society increases.

2) "Convincing Them to Fight: How Rebel Groups Choose Their Recruitment Tactics." Draft Available Here.

Abstract: Why do some rebel groups rely heavily on material incentives for recruitment, while others depend more on ideological appeals? Much of the literature tends to focus on differences in the recruitment tactics between “resource rich” and “resource poor” rebels. In this research note, I investigate how the material and ideological resources available to rebel groups, and their long-term goals, shape their recruitment strategies. I seek to expand our theoretical understanding of rebel recruitment by examining the effects of different types of material resources, not just the presence of absence of such wealth. However, I argue that groups also have agency in formulating their recruitment strategies and that such choices are not based entirely on available economic and social resources. Specifically, I analyze how militants’ long-term goals affect their recruitment. Using novel data on the persuasive recruitment strategies of over 220 rebel groups active across the world, I find strong evidence that groups that exploit a greater breadth of natural resources are more likely to recruit with material incentives. However, I find that while lootable resources affect recruitment patterns, non-lootable resources do not. Surprisingly, I do not find clear evidence that existing ethnic and religious ties help facilitate ideological-based recruitment. Finally, the results indicate that rebel movements with secessionist aims are more likely to rely on ideological-based recruitment strategies. Thus, this note uses novel data to provide nuance to our understanding of how material and social resources affect the recruitment strategies of rebel organizations.
