Efficiency analysis using SBM and PLS-SEM: insights from the Italian judicial system

Recent governmental concerns regarding the persistent long duration of judicial proceedings have drawn attention to efficiency issues in this sector. This paper provides insights into the Italian scenario, investigating potential relationships between Italian judicial efficiency and several latent constructs identified as relatively more significant than others. For this purpose, a two-step procedure was used, considering data envelopment analysis (DEA), precisely the slacks-based measure (SBM), and partial least squares structural equation modeling (PLS-SEM). Beyond ranking courts according to their technical efficiency, findings reveal that judicial efficiency has significant relationships with performance, quality and context features. At the same time, results do not show evidence to support a relationship with proceeding features. What emerges from the work is that the analysis of heterogeneity seems to offer relevant evaluation leverage, and significant differences appear among Italian courts. These insights and the model provided would represent a useful analysis tool for specific policy assessments, supporting the evaluation of regulatory measures and structural reforms relevant to judicial administration.
