“…After processing the data contained in the FS, the EVA values and their components were calculated for each company in the analyzed period. The data was processed by the PIM-DEA Software, following the guidelines by Saurin et al (2010), which recommends input orientation using the DEA-VRS model for industries that operate with variable returns to scale, ensuring that the DMUs correspond to three times the sum of inputs and outputs (15 companies and 5 variables), determining them the degree of efficiency of companies in the sector for each fiscal year. Furthermore, the calculated efficiency scores were used as data for a descriptive statistical analysis to verify their variability and consistency (extending the internal validity).…”

“…Another major model proposed by Banker et al (1984) is called DEA-BCC, in which the evaluated units present variable returns of scale, for which the addition of one unit can generate a nonproportional increase in the volume of products. Saurin et al (2010) claim that the main difference between the CCR and BCC models is the constant return to scale (CRS) for one and variable returns to scale (VRS) for another.…”

“…As stated, they do not prejudice the calculation of EVA. It is necessary to make it clear that this procedure was used to work with a smaller number of variables, considering that the excessive use of them can negatively affect the results, following the precepts of Saurin et al (2010). It is worth mentioning that the two companies were not considered at two different times.…”

PurposeThis paper aims to analyze the economic-financial performance (EFP) and value creation (VC) in the Brazilian construction industry.Design/methodology/approachBased on the theories of strategy and finance, a quantitative-qualitative, descriptive and explanatory and applied study was carried out, contrasting the performance of the Direcional company and the civil construction industry – both listed on the Brazilian Stock Exchange and the Over-the-Counter Market (B3)FindingsThe analysis of the EFP in the Brazilian construction industry shows that EZTEC, Helbor, Trisul and Direcional were the companies with the best EFP in the period. The analysis of the Economic Value Added (EVA®, henceforth EVA), as a VC metric and basis for assessing the relative technical efficiency score by Data Envelopment Analysis (DEA®, henceforth DEA), revealed that the companies Direcional, EZTEC, MRV and CR2 were considered efficient throughout the period covered. The multicriteria methodology for empirical testing of the EFP and VC allowed not only contrasts Direcional's results with the other companies of the construction industry but also offered a complementary tool for comparative analysis of enterprises of different sizes, structures and realities.Research limitations/implicationsRegardless of any contextual limitations, from a theoretical point of view, the research not only helps fill the research gap aforementioned but also expands knowledge on the topic and demonstrates how this multi-criteria methodology (integrating DEA and EVA) can be used to assess EFP and VC in addition to traditional tools. However, this new approach evaluates, at the same time, corporate and sectorial effectiveness by contrasting the efficiency and efficacy (simultaneously) in the generation of performance and value of a company in relation to the industry.Practical implicationsSignificant implications for managerial practice could be noted by offering a tool to improve company performance and creating a competitive benchmarking process for analysts, investors, managers, financing agencies, shareholders, policymakers and business owners, as well as organizations and sectors in similar situations – who need to assess the EFP and VC holistically and improve their decision-making processes.Originality/valueThe uniqueness and innovation of this research come from the original multi-criteria methodology developed, applied and validated for analysis of EFP and VC. This methodology was operationalized through DEA applied to the companies' EVA, making it possible to compare corporate results and those of the whole industry in a balanced way – an unexplored issue in the literature, especially in emerging economies, opening several avenues for future research.

The Brazilian Provisional Act No. 579/2012 established a significant change in the rules applied to the electric energy sector, in particular in relation to the renewal of concessions of power generation, transmission and distribution of power from those who have contract termination between 2013 and 2017. Besides this measure, the electric energy distributors are going through the third Cycle of Periodic Tariff Review, a fact that also foresees the reduction of charges imposed on the electricity, thereby requiring a greater efficiency of its management. Thus, this research analyses the technical efficiency on the electric energy distribution companies. This is a study with a quantitative approach, based on data from 2012. With the application of Data Envelopment Analysis, we determined the relative technical efficiency of 18 companies of the population. The relative technical efficiency reached a score of 100% in seven of the 18 companies analyzed. Efficient firms are spread across Brazil, with a greater concentration in the Southeast. The Municipal Human Development Index, the size of the concession area and the extent of distribution network, as well as the population density are not explanatory to the attainment of efficiency factors.
