- Do Private Labels Build Retailer Brand Equity?: an Empirical ApproachPublication . Xara-Brasil, Duarte; Marreiros, Cristina; Dionisio, AndreiaThis research is focused on retailer’s equity and brand equity, with an application to food retailer’s private labels. The study is supported on existing brand equity studies, namely Aaker, Keller, Yoo & Donthu and Pappu & Quester. The proposed conceptual model was tested through a survey to a sample of consumers, who do most of their food shopping in one of the two main Portuguese retailers. We obtained and validated a measurement and a structural model with appropriate model fit and factorial, convergent and discriminant validity.
- Employer Branding as a Talent Management Tool: A Systematic Literature RevisionPublication . Pinto Dos Reis, Isabel; Sousa, Maria José; Dionisio, AndreiaThe aim of this paper is to present a systematic literature revision (SLR) that shows the relationship between the concept of employer branding (EB) and talent management (TM). Based on the EB model proposed by Backhaus and Tikoo in 2004, and the macro-contingent model for talent management introduced in 2019 by King and Vaiman, we intend both to analyse the theory correlating the EB concept and TM, and to identify TM dimensions that are reflected on the EB concept. A systematic literature revision was carried out using the Preferred Reporting Items for Systematic Reviews (PRISMA) protocol in order to identify and sum up the most relevant studies of the last 10 years concerning these topics. Findings show that scientific literature on the subject grew considerably in the last four years, reflecting the rising concern over the creation of an employer brand at the organisational level. EB explores talent attraction and retention particularly, though, unexpectedly, is also becoming a concept explored by nations to attract a qualified workforce. Analysing selected articles, we may conclude that EB is clearly considered as a tool within the largest process of talent management.
- Nonlinear nexus between cryptocurrency returns and COVID-19 news sentimentPublication . Banerjee, Ameet Kumar; Akhtaruzzaman, Md; Dionisio, Andreia; Almeida, Dora; Sensoy, AhmetThe paper examines how various COVID-19 news sentiments differentially impact the behaviour of cryptocurrency returns. We used a nonlinear technique of transfer entropy to investigate the relationship between the top 30 cryptocurrencies by market capitalisation and COVID-19 news sentiment. Results show that COVID-19 news sentiment influences cryptocurrency returns. The nexus is unidirectional from news sentiment to cryptocurrency returns, in contrast to past findings. These results have practical implications for policymakers and market participants in understanding cryptocurrency market dynamics under extremely stressful market conditions.
