- Cycles of inequality in the marketplace: insights from macro, marketer, and consumer perspectivesPublication . Thompson, Debora V.; Kirmani, Amna; Hamilton, Rebecca; Li, Andy; du Plessis, Christilene; Fernandes, Daniel; Johnson, Guillaume; McFerran, Brent; Ni, Jian; Pavlov, Vladimir; Petersen, Francine; Scheer, Lisa; Vieites, Yan; Wilcox, KeithSeeking inequality via differentiation is a fundamental theme in the marketing literature: consumers derive utility from products that convey socially valued attributes, and marketers target consumers by giving them opportunities to differentiate on socially valued attributes. However, as a large body of evidence shows, inequality can reduce consumer well-being and limit economic growth. In this paper, we take a systemic view of marketplace inequality, examining the interdependence among consumers, marketers, and macro forces in shaping inequality in markets for goods and services. Our broad review of the marketing literature across ten marketing journals and a variety of subdomains within the field (e.g., macromarketing, consumer behavior, marketing strategy, quantitative marketing) suggests that macro forces, marketers, and consumers are all part of a dynamic system in which each contributes to creating, perpetuating, and disrupting cycles of marketplace inequality. By highlighting the process by which inequality can be created, perpetuated, and reduced, we hope to give marketing researchers and practitioners insight into interventions that have the potential to increase consumer well-being and marketer profitability.
- O vazio, o ouro e o medo: representações de copacabana na memória de idososPublication . Rocha, Everardo; Feix, Isabel; Siciliano, Tatiana OliveiraThis paper aims to present the representations of Copacabana related to lifestyles and consumption practices for a group of elderly people in the period that they call “golden years”. Based in a study with ethnographic inspiration, the group’s discourse shows the articulation between the moment they perceive as the ideal of the neighborhood and their own lives. Copacabana for them meant a route that goes from “emptiness” to “gold” and finally to “fear”. The first is represented as empty and lifeless space; the second reflect happiness, consumption and leisure; and the third is perceived as a moment of fear and decadency.
- Social entrepreneurship and broader theories: a critical reassessment and future agendaPublication . Zeyen, Anica; Beckmann, Markus; Müller, Susan; Khanin, Dmitry; Krueger, Norris; Murphy, Patrick J.; Santos, Filipe; Scarlata, Mariarosa; Walske, Jennifer; Zacharakis, AndrewIn 2013, following an AOM workshop on “Social Entrepreneurship and Broader Theories,” we published essays challenging dominant economic, business, and entrepreneurship concepts. We revisit them to reflect on the field’s evolution and remaining gaps. Two essays take a macro perspective, exploring adaptive societies and the tragedy of the commons. Two examine the managerial level, discussing limited practical impact and the need for stronger blended performance metrics. Two focus on entrepreneurship, examining a shift toward community-venture paradigms and critiquing traditional business model tools. Together, they invite a rethinking of the when, why, what, and how of social entrepreneurship research and practice.
- Insect-based dinner products for meat substitution in ordinary diets: developing the quality criteria and experimental products for consumer interventionsPublication . Maya, C.; Flore, R.; Sun, Y.; Costa, A. I. A.; Cunha, L. M.; Rocha, C.; Monteiro, M. J. P.; Osimani, A.; Aquilanti, L.; Borght, M. Van Der; Vandeweyer, D.; Chiriac, I. E.; Peters, M.; Rukov, J.; Roos, N.The growing environmental impact of livestock farming has emphasised the need for more sustainable diets with lower meat consumption, identifying insects as a potential alternative protein source. The Sustainable Insect Chain (SUSINCHAIN) project aimed to incorporate six new insect protein products into regular dinner meals, aiming to replace 20% of meat protein through a six-week dietary intervention in Denmark and Portugal, namely a randomised controlled study targeting families with children and young and childless couples respectively. This paper presents the process undertaken by project partners to develop the specifications and establish the quality criteria for the six study products. Quality criteria focused on the immediate appeal and sensory properties of edible insects as food ingredients, particularly taste, texture, and appearance to promote acceptability. Initial sensory evaluations of product prototypes provided essential feedback for improvement. The development of insect-based food products, including those mimicking traditional meat products, highlighted the significance of sensory quality and consumer perception in product acceptance. Non-meat mimicking items had high sensory appeal, but were not perceived as meat replacements, typically being later added as side dishes or supplements by intervention participants. Balancing insect protein content with sensory appeal presented challenges, highlighting the need to consider portion sizes and presentation. Overall, animal meat protein replacement in dinner meals using insect-based foods requires an integrated approach that combines innovative product development, ongoing quality assessments, and a deep understanding of consumer preferences, crucial for market acceptance and adoption.
- What's driving the decline in entrepreneurship?Publication . Kozeniauskas, NicholasWhy has there been a steady decline in entrepreneurship in the US in recent decades? To answer this question, I develop a general equilibrium occupation choice model and combine it with data on these choices. Skill-biased technical change can account for much of the decline in the relative entrepreneurship rate of more educated people, but cannot explain the decline in the aggregate level of entrepreneurship. The major factors in the decline in the share of people who are entrepreneurs, the firm entry rate, and the size of the entrepreneur sector are rising entry costs and outsized productivity gains by large non-entrepreneur firms.
- Memórias de um tempo de lazer, consumo e alegria: um estudo etnográfico sobre uma casa de idosos no Rio de JaneiroPublication . Feix, Isabel; Rocha, EverardoThis article presents an ethnographic study conducted in a high-end retirement home in Rio de Janeiro, aimed at analyzing the memories of 27 elderly residents (born between 1924 and 1952) from the Brazilian urban elite regarding their leisure, consumption, and sociability practices between the 1930s and 1970s. Based on fieldwork observations, the elders’ narratives were interpreted as collective representations shaped by the processes of modernization, industrialization, and the expansion of mass media. The testimonies reveal how household appliances, automobiles, travel, fashion, media, and advertising strategies became symbolic markers of social distinction, projecting images of prosperity and progress.
- Dietary intake according to different patterns of food preparation in children and adults: results from the Portuguese National Food, Nutrition and Physical Activity Survey (IAN-AF 2015/2016)Publication . Rei, Mariana; Correia, Daniela; Torres, Duarte; Lopes, Carla; Costa, Ana Isabel A.; Rodrigues, Sara S. P.Objective: To investigate associations between dietary intake and patterns of food preparation, by age group. Design: This cross-sectional study analysed dietary intake data from the most recent Portuguese National Food, Nutrition and Physical Activity Survey. Cluster analysis categorized dietary intake based on the source of food preparation. Regression models were used to study the association between dietary daily intake, Healthy Eating Score (HES), and patterns of food preparation. Setting: Portugal, using data representative of the Portuguese population. Participants: A total of 5005 Portuguese residents aged 3 to 84 years were included in the analysis. Dietary intake and food preparation patterns were examined by age group. Results: The predominant pattern of food preparation was food prepared by restaurants, canteens, and other away-from-home establishments (45.9%, 95%CI = 43.8, 48.1%). Children and adolescents in this pattern had significantly higher intakes of energy and carbohydrates but lower protein intake compared to those consuming predominantly home-prepared foods. Among adults and the elderly, this pattern was associated with higher intakes of energy, saturated fats, trans fats, and free sugars, and lower fibre intake. Additionally, children and adolescents whose diets predominantly included food prepared away-from-home showed a decrease in HES (? = -0.7, 95% CI = -1.3, -0.2), and adults experienced a greater reduction (? = -1.2, 95% CI = -1.5, -0.9). Conclusions: In Portugal, consuming food prepared away-from-home is associated with poorer dietary quality, with higher energy and unhealthy nutrient intake and lower HES, suggesting a need for interventions focused on promoting healthier food preparation practices.
- Meta-analysis on the impact of corporate social responsibility initiatives on consumer attitudes and behaviorPublication . Vale, Rita Coelho do; Matos, Pedro Verga; Almeida, Filipa deThe present research conducts a thorough meta-analysis to better understand the relationship and magnitude of the effect of corporate social responsibility (CSR) initiatives on consumers’ behavior and attitudes, including multiple moderators (e.g., type of CSR initiatives, type of industry, and country development level). Data comprises 744 effect sizes, extracted from 165 research articles encompassing 67,270 participants. Altogether, the findings reinforce the importance of CSR to consumers, suggesting that companies benefit from incorporating CSR initiatives in their business practices, having a positive effect of medium magnitude when no specific moderators are considered in the analysis (r?=?.38; linear models?=?.25; correlations?=?.44). However, findings also indicate that when considering specific moderators (e.g., country development, industry type, and cultural characteristics) and consumer responses type (e.g., attitudinal vs behavioral), this magnitude can differ significantly, providing evidence that consumer engagement in CSR activities is multifaceted and does not always translate into the expected outcomes.
- Legal frameworks for blockchain applications: a comparative study with implications for innovation in EuropePublication . Hafe, Francisco Von; Wagle, Yash; Guede-Fernández, Federico; Giordano, Ana Paula; Silva, Luís; Azevedo, SaloméIntroduction: The decentralised nature of blockchain technology challenges traditional legal frameworks, creating regulatory gaps in asset classification, taxation, and consumer protection. In Europe, divergent approaches, from specialised blockchain laws to adaptations of general financial legislation, hinder cross-border deployment and limit blockchain’s potential. These disparities make compliance difficult for firms and increase the risks for consumers. This study compares blockchain regulations across six European geographies: Switzerland, Liechtenstein, and Malta (blockchain-specialised regulators) versus the European Union (EU), Estonia, and Portugal (generalist regulators) to map key divergences in legal maturity, asset classification, taxation, anti-money laundering/know-your-customer enforcement, and supervisory structures. A secondary objective is to evaluate how these differences impact the scalability of innovation. Methods: This study compares blockchain regulations across six European jurisdictions through a three-phase analysis. The scoping phase identified five regulatory themes and selected geographies based on maturity, innovation, and economic specialisation. Primary legal texts and policy data (2020–2025) were analysed to map convergences and divergences between blockchain-specialised and generalist regulators. Results: The comparison reveals differences: blockchain-specialised geographies have dedicated Distributed Ledger Technology laws, centralised oversight, and crypto-friendly tax regimes; for example, Switzerland exempts private capital gains, and Malta offers Value Added Tax exemptions. In contrast, generalist regulators, such as the EU’s Markets in Crypto-Assets Regulation (MiCA), which theoretically harmonise rules, face inconsistent enforcement across member states. Meanwhile, Portugal’s tax exemptions and Estonia’s rigid capital requirements create opposing market incentives. Only Liechtenstein’s Blockchain Act comprehensively regulates Decentralised Finance, whereas other geographies either adapt existing financial regulations or do not regulate it. NFTs face fragmented treatment, are excluded under MiCA, classified as securities in Estonia, and left to case-by-case analysis in Switzerland, which contributes to market uncertainty. Discussion: This study reveals a tension in blockchain governance: specialised geographies demonstrate that comprehensive, tailored frameworks foster mature ecosystems. Conversely, generalist approaches struggle with fragmentation, as seen in MiCA’s uneven enforcement and Estonia’s restrictive licensing. Yet, regulatory ambiguity carries paradoxical benefits; Portugal’s minimal rules and the EU’s transitional gaps have also fueled competitive innovation. For policymakers, these results underscore the importance of striking a balance between oversight and flexibility to foster and scale up innovation.
- Value creation and value capture in NFT business models: insights from blockchain-based venturesPublication . Rezazadeh, Arash; Bohnsack, RenéThis paper sets out to explore how blockchain-based technologies, particularly non-fungible tokens (NFTs), are influencing future business models. Drawing on the relevant literature and a multiple case study of blockchain ventures, we demonstrate how the technology leads to new polyadic mechanisms of value creation and value capture. A clarification of NFTs and related concepts, together with their use values and exchange value determinants, led us to argue that the polyadic mechanisms differ from those in dyadic and triadic business models. Overall, we identify a total of 39 NFT technology affordances that fall into four types: utility, social, financial, and legal affordances. In addition, the NFT business ecosystem is mapped in terms of sources of generativity, mixed-side network effects, and the convergence of complementors within the ecosystem. Finally, this study explores three distinct mechanisms of stakeholder collaboration using NFTs: token distribution and fundraising, polyadic value creation and capture, and smart contract-enabled facilitation of stakeholder interactions. Based on the insights, we discuss the impact of NFTs and blockchain technology on society (illustrated by two cases of NFT ticketing and decentralized apps), and the implications for theory, practice, and policy.
