... One of the first proposals used the Efficiency Contribution Measure (ECM) of each variable (Pastor et al., 2002), via a hypothesis test determining whether an input is relevant or not. Other approaches used regression-based analysis, such as Ruggiero (2005), bootstrapping methodology (Simar and Wilson, 2000a), or enriched the DEA optimization programs using binary variables to model which inputs are selected (Peyrache et al., 2020;Benítez-Peña et al., 2020), as well as statistical methods (Araújo et al., 2014). Another family of approaches performs aggregations of the available variables, creating new variables which inform of the characteristics of the data, but losing interpretability. ...

... Section 4 provides the data description and results of an analysis of 2 Our paper is a substantially revised and extended version of Chapter 2 in Levent Kutlu's dissertation, Market Power and E¢ ciency (2010a). Recently, independent from us, Peyrache and Rambaldi (2013) proposed a similar Kalman …lter model for estimating e¢ ciencies. ...

... In other words, the literature points out the existence of patterns of broad productivity heterogeneity within single industries and relatively less heterogeneity between different sectors. The differences among firms include firm size, (2011), Bartelsman et al. (2013); Navaretti and Damijan et al. (2013); Ridao-Cano and Bodewig (2018) Market structure differences have ambiguous effects on productivity gap reductions Scherer (1967); Cheung and Garcia Pascual (2001); Aghion et al. (2005) Structural differences between the EU 'core' and 'periphery' are significant explanatory factors of productivity gaps Delgado-Rodríguez and Álvarez-Ayuso (2008) Gräbner et al.

The differences between different sectors include technological sophistication, access to value chains and so on. ...

... Public services are closely related to improving the welfare of the community, one of which is through the improvement and distribution of public services. This condition shows that the development of public facilities must be accompanied by an increase in the quality and effectiveness of the service itself, so that it can maximally encourage an increase in the welfare of the people in the area (Cagigas et al. 2021;Lee et al. 2020;Lim & Lee 2021;Sari et al. 2020;Zhu & Peyrache 2017). Public service is an effort made by an agency or bureaucrat to assist the community in achieving certain goals under the community's needs. ...

... On the one hand, a widespread distribution of smaller commercial courts (and consequently a smaller distance between a court and a firm in a default situation) on one district may improve the quality of the relationships among the economic agents on the market (Castro and Guccio, 2016). From this perspective, a lower court concentration can be desirable (Peyrache, Zago, 2016). On the other hand, the aggregation of smaller commercial courts allows us to take advantage of scale economies and judge specialisation (Teixera et al. 2019, Mattson, Tidana, 2019. ...

... The author concludes that the two concepts of efficiency will coincide only if size is uncorrelated with efficiency and if there are no reallocation inefficiencies. The efficiency of the average DMU has been explored by several authors under the denomination of centralised allocation models or industry models (e.g., Peyrache 2013;Peyrache 2015). Note that Färe et al. (1992) is indeed one of the first papers mentioning industry performance and relate that with firm performance. ...

... Finally, some studies negate the relationship between foreign investment and GTFP (Hwang and Wang 2012;Filippetti and Peyrache 2015), believing that the correlation between the two is not significant (Asheghian 2009;Li et al. 2019). ...

... Apparently, after realizing such a problem, Irving Fisher himself, who was an advocate of circularity for indexes in his famous Fisher (1911) book (in the context of price indexes), corrected himself about a decade later, acknowledging the serious problems of this property, stating: "... for the only definite error which I have found among my former conclusions has to do with the socalled "circular test" which I originally, with other 24 Also see Färe et al.

... The behaviour of labour productivity has been widely studied both across European regions (Cuadrado-Roura et al. 2000;Ezcurra et al. 2007) and within individual countries, e.g., across Italian (Giacinto and Nuzzo 2006), British (Gardiner et al. 2020) and Greek (Christopoulos and Tsionas 2004) regions. Filippetti and Peyrache (2015) assessed the role of the technology gap, capital deepening, exogenous technical change, and efficiency change in explaining labour productivity differences in European regions. Basile et al. (2008) analysed the relationship between regional unemployment, wages, and labour productivity differentials in Europe. ...

... In all these cases, technology must satisfy various types of Hicks-neutrality and of homotheticity-very restrictive assumptions. Chambers and Färe (1994) appear to be among the first to thoroughly discuss technologies of the type that obey such conditions (also see Chambers (1988, p. 207) for a related discussion), which were later revisited by , Balk (1998), Balk et al. (2003), Peyrache (2013), Sickles and Zelenyuk (2019, p. 130-137) and with some further developments by Färe et al. (2020). The bottomline of all these works is that the problem is very complex and the solutions that were discovered so far require very strict assumptions on the technology, such as homotheticity and neutrality of technology change (which is very unrealistic) as well as constant returns to scale or its generalizations. ...
