Searching for the source of technical inefficiency in Italian judicial districts : an empirical investigation

In this paper, we conducted a two-stage analysis of technical efficiency in Italian judicial districts by focusing on civil cases in 2006. Unlike most of the works that apply the Data Envelopment Analysis technique to study the justice sector, in the first stage, we employed the smoothed bootstrap procedure to generate unbiased technical efficiency estimates. In the second stage, we used a semi-parametric technique (Simar and Wilson in J Econom 136(1): 31–64, 2007) that produces a robust inference for an unknown serial correlation between efficiency scores. Our results show that technical efficiency is explained by demand factors and supports the conclusion that opportunistic behaviour from both claimants and lawyers negatively affects technical efficiency in Italian judicial districts
