Sustainability
Abstract

Companies need to develop more sustainable management models to support a strategy focused on the environment and society, preventing the sole ambition to maximize economic profits. Several specific tools and frameworks have been developed for the implementation of sustainability management. However, the isolated adoption of new management practices could increase bureaucracy and constrain the development of an effective and systematic sustainability strategy. Based on the development of four case studies of relevant companies based in Portugal, this research presents a cyclical process with the structures, inputs and outputs, and roles in embodying sustainability in Integrated Management Systems (IMS). The originality of the work lies in the level of integration. Beyond identifying interconnection areas, it also specifies the Management Systems Standards (MSS) requirements in each area, assigning different roles in the integration process: drivers, efficient enablers, pathways, and evaluators. These four roles promote the claimed integration in a systematic cyclical process, plan–do–check–act (PDCA), to assist the consolidation of sustainability management. This research reinforces the added value of the IMS. It expands its scope, helping companies implement sustainability effectively and systematically, resulting in the presentation of Conceptual Sustainable Management Systems Standards (SMSS).


006 – The Choice Between Corporate and Structured Financing: Evidence From New Corporate Borrowings

João M. Pinto e Mário C. Santos
European Journal of Finance
Abstract

We examine the factors that influence nonfinancial firms’ choice of issuing standard corporate bonds vis-à-vis contracting structured finance, in the form of project finance or asset securitization arrangements. Using a data set of deals closed by 4,700 European borrowers between 2000 and 2016, we find that informational frictions and issuance costs affect public firms’ borrowing source choices. Findings suggest that borrowers choose structured finance when they are relatively smaller, less profitable, have lower asset tangibility, and seek long-term financing. Our findings also document that borrowers resorting to asset securitization tend to have larger growth opportunity sets. Borrowers resorting to project finance are less creditworthy than corporate bond issuers and, on average, asset securitization deals have an 87.6 basis points borrowing cost advantage over corporate bond deals for switchers.


005 – Online Dating Apps as a Marketing Channel: A Generational Approach

Abstract

Purpose

This study aims to understand if an online dating app is considered an acceptable channel to conduct advertising activities and understand the differences between Generations X, Y and Z for such acceptance.

Design/methodology/approach

A total of 411 Tinder users’ reactions were obtained and analyzed using text mining to compute the sentiment score of each response, and a Kruskal–Wallis H test to verify if there are statistical differences between each generation.

Findings

The results showed positive acceptability toward the marketing campaign on Tinder, especially Z Generation. Nevertheless, the statistical analysis revealed that the differences between each generation are not statistically significant.

Research limitations/implications

The main limitation relates to the fact that the participants, during the data collection, revealed their identification, perhaps leading to acquiescence bias. In addition, the study mainly covered the male population. A balanced sample would be positive to examine any possible differences between gender.

Practical implications

Results provide an essential indication for companies regarding their marketing activities conducted on Tinder to fully exploit the possibility of using Tinder as an alternative and valuable channel to conduct marketing activities.

Originality/value

Up until now, no studies tried to understand the effect of a marketing activity online on an online dating app.


004 – Feed-in Tariff Contract Schemes and Regulatory Uncertainty

Luciana Barbosa, Cláudia Nunes, Artur Rodrigues and Alberto Sardinha
European Journal of Operational Research
Abstract

This paper presents a novel analysis of two feed-in tariffs (FIT) under market and regulatory uncertainty, namely a sliding premium with cap and floor and a minimum price guarantee. Regulatory uncertainty is modeled with a Poisson process, whereby a jump event may reduce the tariff before the signature of the contract. Using a semi-analytical real options framework, we derive the project value, the optimal investment threshold, and the value of the investment opportunity for these schemes. Taking into consideration the optimal investment threshold, we also compare the two aforementioned FITs with the fixed-price FIT and the fixed-premium FIT, which are policy schemes that have been extensively studied in the literature. Our results show that increasing the likelihood of a jump event lowers the investment threshold for all the schemes; moreover, the investment threshold also decreases when the tariff reduction increases. We also compare the four schemes in terms of the corresponding optimal investment thresholds. For example, we find that the investment threshold of the sliding premium is lower than the minimum price guarantee. This result suggests that the first regime is a better policy than the latter because it accelerates the investment while avoiding excessive earnings for producers or excessive payments for consumers.


003 – Anticipating the Duration of Public Administration Employees’ Future Absences

Leandro Costa, Ricardo Ramos e Sérgio Moro
Public Administration Issues
Abstract

Absenteeism affects state-owned companies who are obliged to undertake strategies to prevent it, be efficient and conduct effective human resource (HR) management. This paper aims to understand the reasons for Public Administration Employees’ (PAE) absenteeism and predict future employee absences. Data from 17,600 PAE from seven public databases regarding their 2016 absences was collected, and the Recency, Frequency and Monetary (RFM) and Support Vector Machine (SVM) algorithm was used for modelling the absence duration, backed up with a 10-fold cross-validation scheme. Results revealed that the worker profile is less relevant than the absence characteristics. The most concerning employee profile was uncovered, and a set of scenarios is provided regarding the expected days of absence in the future for each scenario. The veracity of the absence motives could not be proven and thus are totally reliable. In addition, the number of records of one absence day was disproportionate to the other records. The findings are of value to the Human Capital Management department in order to support their decisions regarding the allocation of workers and productivity management and use these valuable insights in the recruitment process. Until now, little has been known concerning the characteristics that affect PAE absenteeism, therefore enriching the necessity for further understanding of this matter in this particular.
