Can War Foster Cooperation? MIchal Bauer in Journal of Economic Perspectives—Volume 30, Number 3—Summer 2016—Pages 249–274

New review paper in highly internationally recognized review journal by Michal Bauer et al. Reviewing the existing research in given are they conclude that: 

The core empirical finding we identify—that exposure to wartime conflict fosters cooperative behavior—resonates with the experience of rapid postwar political, social, and economic recovery in many war-torn societies, as well as their tendency to implement egalitarian social policies, including progressive taxation and gender equality reforms (Tripp 2015; Scheve and Stasavage 2010, 2012). While the human costs of war are horrific, there may at least be some reason for optimism once the violence ends.
