- The intrinsic complexity of collective choice a review of making better choices. design, decisions, and democracyPublication . Gomes, OrlandoThe key element structuring and sustaining social and economic relations is collective decision-making, i.e. the choices that groups (large or small) engage in to accommodate in the best way possible the desires, ambitions, and interests of the involved parties. The book by Charles E. Phelps and Guru Madhavan, Making Better Choices. Design, Decisions, and Democracy (Phelps & Madhavan, Citation2021) offers a systematic, comprehensive, and compelling assessment about collective decision-making. A special emphasis is placed on the complexity of the choice process, which is indissociable from the complex nature of the social and economic environments in which choices take place.
- Emerging Standards and the Hybrid Model for Organizing Scientific Events During and After The COVID-19 PandemicPublication . Gomes, Orlando; Hanaei, Sara; Takian, Amirhossein; Majdzadeh, Reza; Maboloc, Christopher Ryan; Grossmann, Igor; Milosevic, Milos; Gupta, Manoj; Shamshirsaz, Alireza A.; Harbi, Amine; Burhan, Amer M.; Uddin, Lucina Q.; Kulasinghe, Arutha; Lam, Chi-Ming; Ramakrishna, Seeram; Alavi, Abass; Nouwen, Jan L; Dorigo, Tommaso; Schreiber, Michael; Abraham, Ajith; Shelkovaya, Natalya; Krysztofiak, Wojtek; Warkiani, Majid Ebrahimi; Sellke, Frank; Ogino, Shuji; Barba, Francisco J.; Brand, Serge; Vasconcelos, Clara; Salunke, Deepak B.; Rezaei, NimaSince the beginning of 2020, the COVID-19 pandemic has dramatically influenced almost every aspect of human life. Activities requiring human gatherings have either been postponed, cancelled, or held completely virtually. To supplement lack of in-person contact, people have increasingly turned to virtual settings on-line, advantages of which include increased inclusivity and accessibility and reduction of carbon footprint. However, emerging online technologies cannot fully replace, in-person scientific events. In-person meetings are not susceptible to poor internet connectivity problems, and they provide novel opportunities for socialization, creating new collaborations, and sharing ideas. To continue such activities, a hybrid model for scientific events could be a solution offering both in-person and virtual components. While participants can freely choose the mode of their participation, virtual meetings would most benefit those who cannot attend in-person due to the limitations. In-person portions of meetings should be organized with full consideration of prevention and safety strategies including risk assessment and mitigation, venue and environmental sanitation, participant protection and disease prevention, and promoting the hybrid model. This new way of interaction between scholars can be considered as a part of a resilience system which was neglected previously and should become a part of routine practice in scientific community.
- “Fool me once, …”: deception, morality and self-regeneration in decentralized marketsPublication . Gomes, Orlando; Frade, JoãoPurpose – This paper aims to provide an overall review and assessment of the virtues and flaws of decentralized self-regulated markets, discussing in particular the extent to which deceiving attitudes by some market participants might be potentially diluted and contradicted. Design/methodology/approach – To approach deception and morality in markets, the paper follows two paths. First, the relevant recent literature on the theme is reviewed, examined and debated, and second, one constructs a simulation model equipped with the required elements to discuss the immediate and long- term impacts of deceiving behaviour over market outcomes. Findings – The discussion and the model allow for highlighting the main drivers of the purchasing decisions of consumers and for evaluating how they react to manipulating behaviour by firms in the market. Agents pursuing short-run gains through unfair market practices are likely to be punished as fooled agents spread the word about the malpractices they were allegedly subject to. Research limitations/implications – Markets are complex entities, where large numbers of individual agents typically establish local and direct contact with one another. These agents differ in many respects and interact in unpredictable ways. Assembling a concise model capable of addressing such complexity is a difficult task. The framework proposed in this paper points in the intended direction. Originality/value – The debate in this paper contributes to a stronger perception on the mechanisms that attribute robustness and vitality to markets.
- Hand-to-mouth consumers, rule-of-thumb savers, and optimal controlPublication . Gomes, OrlandoContemporaneous research in macroeconomics is experiencing a methodological transition. The well-established representative agent optimal control model, which has served for many decades as the fundamental point of reference to approach most of the aggregate phenomena in economics, is being gradually adapted or replaced. In the new settings, agent heterogeneity prevails: while some agents eventually continue to take optimal intertemporal decisions, others do not possess the ability or the willingness to do so, and therefore resort to simple heuristics in their decision-making processes. In this study, the basic Ramsey growth model of intertemporal choice is reinterpreted in the light of the heterogeneity assumption. Four different frameworks are proposed, and the respective dynamics investigated; these frameworks contemplate: (i) the coexistence of optimal planners and hand-to-mouth consumers; (ii) the coexistence of optimal planners and rule-of-thumb savers; (iii) intertemporal discount rate heterogeneity with endogenous determination of hand-to-mouth behavior; (iv) absence of optimal planning and full heuristic behavior. The derived results point to a richness of outcomes that can only be unveiled once the simple dynamic growth setup is expanded to include different consumption-savings profiles.
