- Determinants of environmental certification in Portuguese hotel companiesPublication . Martins, Catarina Antónia; Alves, Jorge; Silva, AnitaThere are many responsible business and investment initiatives in the field of environmental performance, and among these, certification is a targeted mechanism. In this work, we intend to study the determinants of environmental certification of hotel companies, analysing the Portuguese case. The empirical study considers hotel companies established in Portugal that may operate one or more hotel units. The information retrieved from the Portuguese National Tourism Registry and Iberian Balance Sheet Analysis System database was coded, and a database was built in the SAS software. Variable and data analysis was conducted using descriptive statistics, variable correlations, and the Tobit regression model. The results indicate that affiliation to a brand, hotel classification and hotel size are factors that explain environmental certification, but the return on sales was not statistically significant in this study. These results are important to understanding the determinants of environmental certification in hotel companies since, as a topic of research, it has had little attention prior to the study for the Portuguese case, thus reinforcing the importance of this research. The study also reveals the restricted sample of hotel companies with environmental certification in Portugal, which did not allow computing other study variables that would improve the empirical work.
- Financial performance assessment of branded and non-branded hotel companies. Analysis of the Portuguese casePublication . Martins, Catarina Antónia; Vaz, Clara B.; Alves, JorgePortugal has been experiencing a continuous growth in tourism activity, with hospitality industry as one of the main tourism sectors. Therefore, the assessment of hotel companies’ performance is very important to assist decision processes. The purpose of this paper is to assess the financial performance (FP) of 570 hotel companies operating hotel units in Portugal in 2017. To explore the question of brand affiliation, a comparison was made between hotel companies with similar stars rating and market orientation. In addition, this paper intends to fill a gap in literature studying the Portuguese reality on the subject of brand affiliation. Design/methodology/approach – The present study uses a methodology based on data envelopment analysis (DEA) to assess the overall performance for each company, which further decomposed into the within-group performance and the technological gap. The performance of the hotel company is assessed through the aggregation of multiple financial indicators using the composite indicator (CI) derived from the DEA model. A bivariate analysis based on the Tobit regression to test the robustness of brand effect on FP of hotel companies (HC) was also included. Findings – The empirical results show that branded companies, on average, have significantly better overall FP than non-branded companies. On the one hand, the brand effect tends to improve the within-group FP of HCs and the brand presents a statistically significant positive effect on the FP. On the other hand, the best practices are observed in both branded and non-branded companies. Practical implications – The results of this study illustrate that, globally, the better FP of the branded companies is because of their individual relative companies’ performance and a better model of operation given by the brand effect. Brand affiliation will generally allow for a better FP and essentially a better profitability for invested equity, a higher return on sales and a higher value added per employee. Originality/value – The study provides important theoretical and practical contributions that can assist the strategic decision of the HCs in choosing to operate independently or to adopt brand affiliation. Also, it is innovative because the FP of branded and non-branded HCs is measured not using a set of individual financial ratios but through a single CI that aggregates those financial ratios, using a DEA model.
