Abstract:
Scholars of civil war and insurgency have long posited that insurgent organizations and their state enemies incur costs for the collateral damage they cause. We provide the first direct quantitative evidence that wartime informing is affected by civilian casualties. Using newly declassified data on tip flow to Coalition forces in Iraq we find that information flow goes down after government forces inadvertently kill civilians and it goes up when insurgents do so. These results have strong policy implications; confirm a relationship long posited in the theoretical literature on insurgency; and are consistent with a broad range of circumstantial evidence on the topic.

Abstract:
Why did violence decline in Iraq in 2007? Many credit the "surge," or the program of U.S. reinforcements and doctrinal changes that began in January 2007. Others cite the voluntary insurgent stand-downs of the Sunni Awakening or say that the violence had simply run its course after a wave of sectarian cleansing. Evidence drawn from recently declassified data on violence at local levels and a series of seventy structured interviews with coalition participants finds little support for the cleansing or Awakening theses. This analysis constitutes the first attempt to gather systematic evidence across space and time to help resolve this debate, and it shows that a synergistic interaction between the surge and the Awakening was required for violence to drop as quickly and widely as it did.

Abstract:
A central question in intrastate conflicts is how insurgents are able to mobilize supporters to participate in violent and risky activities. A common explanation is that violence committed by counterinsurgent forces mobilizes certain segments of the population through a range of mechanisms. We study the effects of civilian casualties in Iraq and Afghanistan to quantify the effect of such casualties on subsequent insurgent violence. By comparing uniquely detailed micro-data along temporal, spatial, and gender dimensions we can distinguish short-run 'information' and 'capacity' effects from the longer run 'propaganda' and 'revenge' effects. In Afghanistan we find strong evidence that local exposure to civilian casualties caused by international forces leads to increased insurgent violence over the long-run, what we term the 'revenge' effect. Matching districts with similar past trends in violence shows that counterinsurgent-generated civilian casualties from a typical incident are responsible for 1 additional violent incident in an average sized district in the following 6 weeks and lead to increased violence over the next 6 months. There is no evidence that out-of-area events—errant air strikes for example—lead to increased violence, nor is there evidence of short run effects, thus ruling out the propaganda, information, and capacity mechanisms. Critically, we find no evidence of a similar reaction to civilian casualties in Iraq, suggesting the constraints on insurgent production of violence may be quite conflict-specific. Our results imply that minimizing harm to civilians may indeed help counterinsurgent forces in Afghanistan to reduce insurgent recruitment.
