Benchmarking technical efficiency of water utilities in Chile under heterogeneity: A latent class frontier approach Maziotis, Alexandros Molinos Senante, María Producción Científica Benchmarking the technical efficiency of water utilities is essential for informing evidence-based regulatory decisions. However, conventional performance assessment models often rely on the assumption of homogeneity among utilities. This study addresses this limitation by applying Latent Class Stochastic Frontier Analysis to 22 Chilean water utilities over the period from 2010 to 2017. The average technical efficiency scores for companies in Class 1 and Class 2 were 0.91 and 0.88, respectively. Companies in Class 1 exhibited stable performance over time, with efficiency scores ranging from 0.88 to 0.92. In contrast, companies in Class 2 demonstrated greater variability, with scores ranging between 0.85 and 0.93. 2025-11-14T10:38:26Z 2025-11-14T10:38:26Z 2025 info:eu-repo/semantics/article Utilities Policy, 2025, vol. 97, p. 102076 0957-1787 https://uvadoc.uva.es/handle/10324/79692 10.1016/j.jup.2025.102076 102076 Utilities Policy 97 eng https://www.sciencedirect.com/science/article/pii/S0957178725001912 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © 2025 The Author(s) Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier SI
