- The socioeconomic impact of a music festival on a community: the case of Bons Sons in Cem Soldos villagePublication . Teixeira, Maria João; Coelho, Sandra Lima; Cunha, Mariana; Seixas, CarlosMusic festivals have historically celebrated regional culture and community (Duffy, 2000). Over time, their commercial aspects have overshadowed community goals, favouring urban areas over rural ones. However, the rise of nostalgic tourism offers hope for rural revitalization. This research examines the Bons Sons Festival, evaluating its cultural, social, and economic impacts through interviews, surveys, and regression analysis. Results indicate that the festival positively impacts the local economy of Cem Soldos village, particularly in accommodation and food services, and fosters community projects throughout the year.
- Normalizing VES production functions: extending the supply-side system approachPublication . Río, Fernando del; Rebelo, FranciscoThis paper extends the Klump et al. (2007) normalization procedure to Variable Elasticity of Substitution (VES) production functions. Normalization addresses identification issues in VES model estimation, allowing joint estimation of substitution elasticities and factor-augmenting technical change, while offering a tractable extension of the normalized supply-side system that bridges the gap between CES and more flexible VES specifications.
- Eu-nique perspectives? Analysing contrasting positions on the russo-ukrainian conflict within the EUPublication . Ramos, Matilde; Sá, Filipa; Silva, Noa; Resende, Mariana; Castro, IsabellaThis research examines the various positions adopted by the European Union (EU) Member States in response to the ongoing Russo-Ukrainian conflict, since its reignition on February 24th, 2022. The study is based on a content discourse analysis of speeches and official statements released by individual EU Member States, namely Poland, owing to its historical relations with the Eastern Bloc and its noteworthiness in accommodating refugees; followed by Germany and its pivotal role in providing military equipment to Ukraine; and lastly, Hungary, due to the contentious public statements issued by its Prime Minister, Viktor Orbán. The analysis is complemented by an examination of the broader foreign policy orientations of these countries that shape their responses. The primary aim is to assess whether the Union maintains a cohesive consensus on the conflict or if diverging positions weaken its support for Ukraine. Ultimately, through a juxtaposition of opinions issued by Poland, Germany, and Hungary against the overall EU stance, we conclude that the European Union’s support for Ukraine is not as robust and cohesive as expected.
- Channel integration puzzle: internal obstacles, industry drivers and omnichannel capabilitiesPublication . 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 fatalitiesPublication . Gruda, Dritjon; Gonçalves, Ricardo; Zadegan, Milad SharafiEconomic 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 comparabilityPublication . Fontes, Joana Cardoso; Panaretou, Argyro; Shakespeare, CatherineThis 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 IndiaPublication . Duarte, Paulo; Meneses, Raquel; Silva, Susana C.; Tharakan, Riya RoyThis 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 traditionPublication . Martins, Nuno OrnelasThis 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.
