- Certification of Portuguese companies as an inducer of profitability: A panel data approachPublication . Dos Santos, Anabela Saraiva; Pinto, António; Manuel Nogueira Reis, Pedro; Neves, M. ElisabeteWith the globalization and internationalization of markets, companies need to be more competitive and offer high-quality guarantees to consumers, suppliers, banking institutions, and shareholders. Thus, the objective of this paper is to measure the impacts that these guarantees, analyzed through quality management, environmental management, and management of occupational health and safety standards, will have on the return on assets (ROA) of companies classified by sector of activity, considering each of the certifications individually and as a whole. The panel data approach methodology was used for 10 years in Portuguese- certified companies between 2010 and 2019. The Chow test, the Breusch-Pagan, and the Hausman test were applied to identify a more feasible model between the pooled OLS and the random or fixed effects model. Furthermore, the cluster-robust standard errors model was applied. The results show the existence of synergies when adopting more than one certification to improve firm performance. Moreover, the single certification estimate by sector results are significant and can be positive drivers of profitability, but only for companies in the manufacturing industries related to natural resources. However, they trigger negative results in the accommodation, catering, and information and communication sectors.
- How Do Banking Characteristics Influence Companies Debt Features and Performance during COVID-19? A Study of Portuguese FirmsPublication . Reis, Pedro; Pinto, AntónioAbstract: This paper investigates how bank characteristics (market share, principal shareholders, profitability, and size), and the gender of the company’s board members, along with their supervisory abilities, influence the firm’s performance, cost of debt, and leverage. We extracted relevant data from a sample of nearly 18,300 Portuguese companies in 2020 (the pandemic year) to build our model with all the main explanatory variables; then, through the least absolute shrinkage and selection operator estimation, we reduced the variables. The robust ordinary least-squares standard-errors approach was applied by company size. Our findings allowed us to observe the crucial negative role of multiple bank relations, but only on the returns of small companies. A decrease in bank relations led to an increase in debt cost and reduced leverage across larger companies. Profitable banks generate higher company returns, mainly for small companies. Furthermore, the better-informed bank shareholders (management, institutional, or government) persuaded the banks to charge higher interest rates, resulting in a higher leverage ratio for companies of average size. Female board members tended to vote for lower debt ratios due to greater risk aversion, while the opposite was true of male board members. The supervisory capacity of the board in the area of bank relations showed a more substantial link with the increased financing costs of small companies. In brief, bank characteristics and board gender were strongly associated with the financial aggregates of companies relative to their size. This work contributes to the literature by using new bank characteristics and an original variable representing board ability to cope with bank relations. To the best of our knowledge, this is the first study to determine the association of the above characteristics in the Portuguese market relative to company size, and their impact on profitability, cost of debt, and leverage. The company board and banking systems should evaluate the impact of their decisions on corporate activity and make necessary adjustments.
