In an earlier study Doyle and Sambanis (2000) [Doyle, Michael W., and Nicholas Sambanis. 2000. "International Peacebuilding: A Theoretical and Quantitative Analysis." American Political Science Review 94(4):779--801.] showed that United Nations (UN) peace operations have made positive...

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...

Earlier studies have shown that United Nations peace operations make a positive contribution to peacebuilding efforts after civil wars. But do these effects carry over to the period after the peacekeepers leave? And how do the effects of UN peace operations interact with other determinants of...

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...

How do the outcomes of international wars affect domestic social change? In turn, how do changing patterns of social identification and domestic conflict affect a nation's military capability? Models that link structural variables, power politics, and the individuals that constitute states are...

In the literature on civil war onset, several empirical results are not robust or replicable across studies. Studies use different definitions of civil war and analyze different time periods, so readers cannot easily determine if differences in empirical results are due to those factors or if...

Why do groups want to secede and where are we most likely to see demands for self-determination? This paper proposes an economic explanation whereby a tradeoff between income and sovereignty implies that, other things being equal, richer regions are more likely to want more autonomy and conflict...

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...
