In this paper we investigate the relationship between the number of lawyers and civil litigation across Italian provinces over the period 2000-2005. First, we document the existence of a positive correlation between the number of lawyers and litigation. We then employ a 2SLS approach to verify the existence of a causal effect. We use as an exogenous source of variation for the number of lawyers the differences among provinces in the proximity of a law school in 1975. Our results show that the number of lawyers has a positive effect on litigation and that the magnitude of this effect is large.
