STREET CRIME AND STREET CULTURE*
构建模型说明声誉关注如何支撑街头犯罪文化，即使直接激励很弱；模型解释了暴力犯罪中低经济回报、年轻贫困群体受害多、跨区域差异大等事实，并得出社会资本有负面效应的政策启示。
A model shows how reputation concerns can support widespread street crime, a street culture, where the direct incentives for such behavior are weak. There are social benefits to street reputations, but those benefits are dominated when reputation concerns draw into crime those who obtain no direct gain from it. The model matches facts about violent crime that a standard model cannot easily explain including low monetary returns, disproportionate victimization of the young and poor, and high variance in rates across small distances. The model generates novel implications for policy and social science, including a negative effect of social capital.
