“…It should be stressed that in this type of literature, the measurement of local efficiency from a global approach is common, compared to other research streams focused on specific services such as the local police (Davis and Hayes, 1993); fire services (Jaldell, 2019); libraries (De Witte and Geys, 2013); educational services (Ferraro et al., 2021); water supply (Brettenny and Sharp, 2016; Benito et al., 2019); waste collection and street cleaning (Worthington and Dollery, 2001; Guerrini et al., 2017; Pérez‐López et al., 2018, 2021a, 2021b; Romano et al., 2020; Benito et al., 2021); maintenance of regional roads (Kalb, 2014); and urban public transport (Campos‐Alba et al., 2020). This is because the municipalities are multiproduct organizations in which the joint use of inputs generates a variety of outputs (Cherchye et al., 2014).…”
