We introduce a model of spending on police services which we use to interpret the data. In this model, we assume that the decision to commit a crime is...

There is extensive literature, both theoretical and empirical, on the effects of social identity on a wide range of economic and non-economic outcomes. However, there is only scarce knowledge about how social identity is affected by policies or market structure. We address the question how...
