The editor of the Journal of Conflict Resolution has accepted my paper on “Lessons on political violence from America’s post-9/11 wars”. This paper is co-authored with Jacob Shapiro. It analyzes the bargaining failures that led to the onset of these two wars and investigates local-level temporal and spatial variation in the intensity of combat. The paper reviews a large literature in political science that studies these two wars, summarizes the uniquely rich data on both conflicts, and outlines potential avenues for future research. The paper is available under the Research link on my website.
