This paper uses Two-stage Data Envelopment Analysis (“TS DEA”) and Stochastic Frontier models (“SF models”) to compare the efficiency performance of national postal operators. It applies TS DEA and SF methods to the same postal operator dataset, and compares their efficiency rankings and the way they account for the effect of exogenous variables. Section 2 contains a literature review. Section 3 applies two-stage DEA with bootstrapped Tobit regression and SF models to the database used in Pierleoni and Gori (2013). Section 4 concludes. The critical aspect of this paper is limited data availability (77 observations, seven operators for 11 years). This calls for caution in interpreting the results; there is a need for a combination of qualitative and quantitative analysis to fully grasp differences in performance between postal operators.
