Summary On November 30, 2022, Springer published the book Micro-evidence for Peacebuilding Theories and Policies, co-authored by Professor Kazuhiro Obayashi at the Graduate School of Law, Hitotsubashi University. In this book, multiple researchers provide insights into theories and policies of post-conflict peacebuilding. The analysis is based on micro-level evidence, considering civil norms and values. Professor Obayashi and his co-authors’ chapter studies the relationship between violence during war, risk and time preferences, and participation in sociopolitical organizations in the northwestern region of Pakistan. His findings reveal that war-related violence increases victims' risk-averseness, influencing their social activities. However, local organizations function as safety nets, mitigating the impact of violence.
