Critical barriers to joint production: datu politics and insurgent fragmentation in Southern Philippines

In understanding how groups overcome collective action problems of mass mobilisation in civil wars, a joint-production explanation was put forth in the civil war literature. According to this explanation, collective action can be successful when leaders at the centre tie the public good – violence towards the overall goal of the movement – inextricably to private interests of actors at the peripheral levels of the conflict. It is through this logic of joint production that we can understand the failures of the Islamic insurgencies in Southern Philippines and the spiralling levels of violence. Where other movements cohered under a common identity, the Islamist insurgency in Southern Philippines saw high degrees of fragmentation. In this paper, I argue that cleavages of regionalism created by colonial disruptions of land and social relations became a critical barrier for insurgent joint production. Furthermore, interactions between these identities and the state can pose further collective action problems. In Southern Philippines, insurgent leaders are unable to cut across these cleavages, resulting in increasingly fragmented movements and protracted conflict. Therefore, I argue that a joint-production approach to understanding civil wars can be especially promising when culturally and historically situated to explain why collective action often fails in civil war.
