Quantitative studies of civil war have focused either on war's onset, or its termination, producing important insights into these end points of the process. The authors complement these studies by studying how much war we are likely to observe in any given period. To answer this question, they...

The authors combine an empirical model of external intervention, with a theoretical model of civil war duration. Their empirical model of intervention allows them to analyze civil war duration, using"expected"rather than"actual"external intervention as an explanatory variable in the duration...

Some theorists of ethnic conflict argue that the physical separation of warring ethnic groups may be the only possible solution to civil war. Without territorial partition and (if needed) forced population movements, they argue, ethnic war cannot end and genocide is likely. Other scholars have...

This paper reviews the booming literature on civil war. It presents the major theoretical perspectives and key empirical results on the determinants of civil war. The paper identifies controversies in the field and suggests ways to improve and organize our research. The conclusion outlines...

Civil wars are far less likely to end in peace agreements than are international wars, and more than a third of civil wars restart within a few years. This may be due to the time-inconsistency of peace settlements in civil wars: once the rebels demobilize, they lose bargaining power and the...

Quantitative studies of civil war have focused on war initiation (onset) or war duration and termination and produced important insights into these processes. An empirical analysis of civil war prevalence is used to show that the prevalence or amount of war observed at any given time is...

A booming quantitative literature on large-scale political violence has identified important economic and political determinants of civil war. That literature has treated civil war as an aggregate category and has not considered if identity (ethnic/religious) wars have different causes than...

The empirical literature on civil war has seen tremendous growth because of the compilation of quantitative data sets, but there is no consensus on the measurement of civil war. This increases the risk of making inferences from unstable empirical results. Without ad hoc rules to code its start...

The two volumes of Understanding Civil War build upon the World Bank's prior research on conflict and violence, particularly on the work of Paul Collier and Anke Hoeffler, whose model of civil war onset has sparked much discussion on the relationship between conflict and development in what came...
