  • Channel integration puzzle: internal obstacles, industry drivers and omnichannel capabilities
    Publication . Hajdas, Monika; Radomska, Joanna; Kawa, Arkadiusz; Klimas, Patrycja; Silva, Susana C.
    Purpose – In this paper, we aim to advance the research on how companies navigate channel integration by examining the internal and external challenges they encounter. Specifically, we investigate how internal obstacles and external industry drivers affect the level of channel integration. Design/methodology/approach – In our quantitative study, we collected the relevant data from 412 firms operating in over 20 diverse industries and offering both online and offline channels. We also explore how organizational omnichannel capabilities moderate the relation between internal and external factors and the level of channel integration. Findings – Our results indicate that channel integration is hindered by internal barriers, including limitations in operational efficiency, strategy and organizational culture. Additionally, external pressures stemming from industry-specific factors contribute to these challenges. Conversely, positive influences may arise from micro- environmental factors, such as an existing customer base already literate with omnichannel solutions or competitors advanced in omnichannel strategies. Originality/value – To evaluate the effects of channel integration, we examine its influence on performance across multiple dimensions (short-term, long-term and comparative), extending prior research that has predominantly emphasized short-term performance metrics.
  • Quit playing games with our lives: layoffs predict road traffic fatalities
    Publication . Gruda, Dritjon; Gonçalves, Ricardo; Zadegan, Milad Sharafi
    Economic downturns are typically associated with fewer traffic accidents due to reduced driving. However, the psychological and social shocks of sudden job loss may counterintuitively increase risk on the road. In this paper, we examine whether mass layoffs announcements are associated with short-term increases in traffic fatalities in the United States using spatial autoregressive models. Merging monthly U.S. county-level data on mass layoffs with motor vehicle fatality counts, we find a significant uptick in monthly traffic fatalities following major layoff events. This pattern persists after accounting for seasonal trends and regional factors, including unemployment rates and weather conditions. These findings suggest that the stress and disruption caused by mass layoffs can have deadly consequences beyond the workplace. We discuss psychological mechanisms (e.g., distress-related driving impairment) and implications linked to short-term rises in traffic fatalities and public health implications for fatal crash risk.

  • The effect of IFRS 9 on comparability
    Publication . Fontes, Joana Cardoso; Panaretou, Argyro; Shakespeare, Catherine
    This study examines the impact of IFRS 9 adoption on accounting comparability in the banking industry. Our findings indicate that overall the adoption of IFRS 9 is associated with a decrease in accounting comparability. The adoption of the expected credit loss model is identified as the primary driver of reduced comparability, while we provide some evidence that IFRS 9 classification and measurement framework and IFRS 9 hedge accounting rules are associated with an increase in comparability. Although we document a decline in comparability during our sample period, we do not draw conclusions on the long-term impact of the expected credit loss model on comparability or its effect on the informativeness of accounting numbers.
  • Cultural contrasts in vegan food choice: a multi-methods comparative analysis of consumption values in Portugal and India
    Publication . Duarte, Paulo; Meneses, Raquel; Silva, Susana C.; Tharakan, Riya Roy
    This study examines the impact of consumption values on vegan food purchase intentions through a cross-cultural comparison between India and Portugal, two culturally distinct countries with divergent food traditions and value systems. Using the Theory of Consumption Values (TCV) as the framework, we analyze how functional, emotional, social, epistemic, conditional, and ecological values impact vegan purchasing decisions. We utilize both Partial Least Squares Multigroup Analysis (PLS-MGA) and Necessary Condition Analysis (NCA) on 394 responses collected via self-administered surveys. Results show significant differences across countries: Indian consumers are primarily influenced by functional price, conditional, and emotional values, while Portuguese consumers tend to rely more on epistemic and functional quality. Notably, ecological value appears as a key predictor in both contexts. NCA results indicate that several values—particularly ecological, conditional, and functional price—are necessary (but not sufficient) for vegan food purchase intention. These findings challenge the TCV’s assumption of additive and interchangeable value contributions, highlighting the importance of necessity-based reasoning in consumption choices. This study contributes theoretically by expanding TCV with ecological value and methodologically by incorporating NCA. Practically, it provides actionable insights for marketers seeking to promote vegan consumption in culturally diverse markets.
  • Marshall and the notions of welfare and value in the Cambridge tradition
    Publication . Martins, Nuno Ornelas
    This article analyses the notions of welfare and value in the contributions of Alfred Marshall, and how they were developed or criticised within the Cambridge economic tradition, especially by authors like Piero Sraffa and Amartya Sen, who, like Marshall, saw themselves as continuators of classical political economy (albeit with different interpretations of the latter). The analysis is conducted drawing on the stratified ontology adopted in critical realism. It is argued that contributors developing or criticising Marshall placed their emphasis on different aspects, which can be fruitfully identified in terms of the critical realist stratified ontology, depending both on their analytical purposes and strategic intentions when engaging in academic debate. The distinction between welfare and value is also shown to be essential to the Cambridge economic tradition, and its stance towards modes of socio-economic organisation.
  • The role of managers in driving effective paid media strategies in an advertising agency
    Publication . Silva, Susana Costa e; Oliveira, Bianca Sofia; Lemos, Francisco Figueira
    Purpose: This paper develops a practical model for the critical activities of the paid media manager in driving the successful implementation of digital paid advertising campaigns. Originality/value: Based on previous articles about the revolution in the advertising sector through digital and social media (Araújo et al., 2020; Helberger et al., 2020; Liu-Thompkins, 2019), the study responds to latent calls for further research on the roles and skills required by advertising professionals in the face of the digital transformation of advertising practices. In addition, we also related these professionals’ skills to the campaigns’ perceived success. Design/methodology/approach: We undertook a qualitative multi-case study, conducting semi-structured interviews involving paid media firms investing in digital advertising. The interviews were analyzed using the Gioia Methodology to ensure qualitative rigor in performing inductive research.Findings: We found that paid media managers must challenge client briefings, collaborate with creative teams, and dynamically adjust campaign elements for optimization. The key skills must include technical proficiency, information management, critical thinking, creativity, collaboration, and communication. Successful implementation leads to efficient targeting, real-time content adaptation, and cost-effectiveness. The study offers a roadmap for advertising agencies to effectively implement digital ad campaigns, namely from the recruiting and continuous upskilling of Paid Media Managers by identifying their critical roles to the businesses’ assistance in allocating advertising budgets more effectively by providing a thorough understanding of the benefits inherent in digital advertising investments.
  • Teaching and learning with artificial intelligence
    Publication . Magalhães, Andreia; Andrade, António
    Artificial Intelligence (AI) has significant potential to revolutionize teaching and learning methods by providing innovative tools that personalize teaching and make the learning process more efficient. In this way, it is possible to create dynamic scenarios more easily, promoting the evolution of teaching towards a model based on the development of skills, which requires students to perform more actively. Considering that, between 2023 and 2024, Gartner places Generative AI at the peak of inflated expectations in its Hype Cycle, it becomes pertinent to analyze how learning and teaching with AI during this period. In this context, this work aims to conduct a scoping review using the Scopus database, covering the aforementioned period. The data obtained will be subjected to a content analysis, with the purpose of investigating the added value of AI in the way learning and teaching are carried out.
  • OECD labour share trends: factor efficiency vs. market distortions in a neoclassical framework
    Publication . Rio, Fernando del; Rebelo, Francisco
    We find that, for the vast majority of the 29 OECD countries, capital efficiency has declined, while labour efficiency has increased. Moreover, capital and labour exhibit a relatively high degree of complementarity. On average, countries with a larger relative decline in capital efficiency have also experienced a greater decline in the labour share. This pattern is consistent with the neoclassical theory of functional income distribution: if capital and labour are gross complements, a decline in the relative efficiency of capital reduces the demand for labour, thereby lowering equilibrium wages and the labour share. In some countries — including the United States, the United Kingdom and Australia — this mechanism can accurately account for much of the observed evolution in the labour share, while in others — including the three largest European economies (Germany, France and Italy) — market frictions and distortions affecting labour demand have played a more prominent role. Policies aimed at halting the decline in capital efficiency, or mitigating market frictions and distortions, can therefore enhance productivity and support wage growth.
