Publication . Fernandes, Catarina; Pires, Rui A.R.; Alves, Maria-Ceu Gaspar

Digital technologies have changed and disrupted the dynamics of the economy and society as a whole, offering new opportunities for entrepreneurs with potential impact on economic, environmental, and social value creation. This paper examines the scientific research on digital entrepreneurship (DE) and sustainability based on data from Scopus database. The main purpose is to identify both the predominant themes and further research opportunities to this topic. This study uses a bibliometric analysis, analyzing and synthesizing research on DE and sustainability, based on a total of 58 publications. Co-word analysis used to identify the conceptual structure reveals three thematic clusters: (1) innovation and entrepreneurship, (2) digital transformation: strategy and business models, and (3) sustainability and sustainable development goals. For each thematic cluster, the most significant contributions are presented. Further, this paper offers a future research agenda and holds significant implications for the theory and practice of the different subtopics of DE and sustainability.

The impact of board characteristics and CEO power on banks’ risk-taking: stable versus crisis periods

Publication . Fernandes, Catarina; Farinha, Jorge; Martins, Francisco Vitorino; Mateus, Cesário

We examine the impact of board structure, CEO power and other bank-specific factors on bank risk-taking for a sample of 72 publicly listed European banks in both stable and crisis periods. Using a simultaneous equations approach, our main findings indicate that the proportion of independent directors, the board size, and Chief Executive Officer (CEO) power affected bank risk-taking negatively during the recent financial crisis. On the contrary, institutional shareholder ownership and the presence of an ex-CEO as Chairman influenced bank risk-taking positively. Additionally, we separately analyse stable and crisis periods and observe that in the pre-crisis period only board independence and institutional ownership keep the same impact on risk while CEO power has no influence and the existence of an ex-CEO as Chairman reduces risk-taking by banks. We conclude that different governance characteristics have different relevance for banks’ risk-taking contingent on the economic environment being one of stability or crisis.

Exploring the conceptual structure of the research on innovation in hotels through co-word analysis

Publication . Fernandes, Catarina; Pires, Rui A.R.

This paper presents the results of a bibliometric analysis of published academic research on innovation in hotels. In particular, it aims to analyze the conceptual structure of the field, covering the period until October 2020, and predict emerging trends. This approach provides an exhaustive analysis of 334 papers collected from the Scopus database. Co-word analysis used to identify the conceptual structure reveals four clusters: (1) technological innovation, (2) innovativeness and innovation strategy, (3) knowledge and employee innovative behavior, and (4) performance as an outcome of organizational capability to innovate. The present study contributes to the literature by increasing the accumulation of knowledge on research topics, providing an up-to-date review on hotel innovation literature, and setting forth an agenda for future research.
