犯罪率在时间和空间上的高度差异是社会科学中最古老的难题之一;这种差异似乎太大，无法用犯罪的外生成本和收益的变化来解释。我们提出了一个模型，在这个模型中，社会互动在个体之间产生了足够的协方差来解释犯罪率的高跨城市方差。这个模型提供了一个社会互动指数，表明社会互动的数量在轻微犯罪中最高，在更严重的犯罪中中等，在谋杀和强奸中几乎可以忽略不计。
The high variance of crime rates across time and space is one of the oldest puzzles in the social sciences; this variance appears too high to be explained by changes in the exogenous costs and benefits of crime. We present a model where social interactions create enough covariance across individuals to explain the high cross-city variance of crime rates. This model provides an index of social interactions which suggests that the amount of social interactions is highest in petty crimes, moderate in more serious crimes, and almost negligible in murder and rape.
