Poverty and Witch Killing
利用坦桑尼亚农村降雨变化估计收入冲击对谋杀的影响，发现极端降雨导致“巫术”谋杀（通常是老年女性被亲属杀害）大幅增加，但不影响其他谋杀。
This study uses rainfall variation to estimate the impact of income shocks on murder in rural Tanzania. Extreme rainfall (drought or flood) leads to a large increase in the murder of "witches"—typically elderly women killed by relatives—but not other murders. The findings provide novel evidence on the role of income shocks in causing violent crime, and religious violence in particular. Copyright 2005, Wiley-Blackwell.
