Some forgotten equilibria of the Bertrand duopoly!?
No full textThis note analyzes the Bertrand duopoly with constant but asymmetric marginal costs on a market with homogenous products. It is shown that there exist some equilibria that are ignored in the literature on IO. In addition, in this setting (perfectly or nearly perfectly) competitive equilibria exist.
Heterogeneous Behavioral Rules in the Oligopolistic Case
No full textIn a static symmetric duopoly the set of behavioral rules is extended to different types of markup pricing. Using an equilibrium concept suggested in Pasche (2001), it is shown that dependend on the markup neither pure Cournot nor pure Bertrand behavior is a behavioral equilibrium profile. Instead, there is a rationale for the usage of simple heuristics. The presence of markup rules leads to Stackelberg outcomes. Furthermore, pure markup behavior is more competitive than in Cournot case but less competitive than in Bertrand case. It is shown, that multiple behavioral equilibria and heterogeneous behavior may arise, where at least one player uses price setting strategies.oligopoly, markup rules, heterogeneity, behavioral equilibrium.
A Bertrand-Edgeworth-oligopóliumok (Bertrand-Edgeworth oligopolies – a survey of the literature)
No full textAz irodalomban az olyan oligopolmodellek, amelyekben mind az ár, mind a mennyiség döntési változó, Bertrand-Edgeworth-oligopóliumok néven ismertek. E tanulmányban a Bertrand-Edgeworth-oligopóliumokkal kapcsolatos érdekesebb eredményeket tekintjük át. Tárgyaljuk a Bertrand-Edgeworth-típusú oligopolmodellek specifikációját, a Nash-egyensúly létezését, a Nash-egyensúly meghatározását és a Bertrand-Edgeworth-oligopóliumok alkalmazásait. / === / Oligopoly models in which both price and quantity are decisive variables are known in the literature as Bertrand-Edgeworth oligopolies, the most interesting results with which are surveyed in this paper. The author assumes the existence of the Nash equilibrium, as the specification of Bertrand-Edgeworth-type oligopoly models, the determination of the Nash equilibrium, and the application of Bertrand-Edgeworth oligopolies

More than just emotional intelligence online: introducing “digital emotional intelligence”
No full textThe ubiquitous nature of emotional intelligence, as a central theme in every aspect of our lives—be it at work, school, or home—coupled with the growing prevalence of digital interactions, makes it fundamental to develop our understanding of emotional intelligence in a digital world. However, the digital world represents more than just a contextual factor to consider, as interactions in digital environments require digital competence. The objective of this paper is to conceptualize “digital emotional intelligence” as the integration of both emotional intelligence and digital competence. The model we propose posits that trait emotional intelligence predicts attitudes toward digital competence, while digital ability emotional intelligence is predicted by digital competence skills and digital competence knowledge. Using a self-reported questionnaire on 503 respondents, a structural equation model highlights a positive relationship between trait emotional intelligence and attitudes toward digital competence

Emotional intelligence in digital interactions ::a call for renewed assessments
No full textEmotional intelligence (EI) has been a subject of academic investigation for thirty years. There has been much debate on how to measure these forms of EI and the reliability of their assessment, but the actual context in which emotional intelligence is developed and used has interestingly received scarce interest. More specifically, a critical gap exists in considering the rise and impact of digital interactions on emotional intelligence. Indeed, with the rise of social media and the increase in digital interactions, emotions are inextricably related to our behavior online. It is thus fundamental to adapt the assessment of EI in digital contexts. This paper aims to address this gap by suggesting assessment methods that account for the specificities of the interactions in the digital world. We start by acknowledging the variety of digital interactions and provide a categorization of them using the theories of media richness and media synchronicity. We then illustrate the potential for renewed assessments in self reports and performance tests at different levels, from item contextualization to digital assessment of EI. By integrating the digital dimension in emotional intelligence assessment, this paper aims to bring a novel perspective on measuring EI in digital interactions
Key factors in digital literacy in learning and education: a systematic literature review using text mining
No full textThis research aims at providing an overview of the research field of digital literacy into learning and education. Using text mining, it reviews 1037 research articles published on the topic between 2000 and 2020. This review reveals that there is a plurality of terms associated with digital literacy. Moreover, our research identifies six key factors that define the literature, which are information literacy, developing digital literacy, digital learning, ICT, social media, and twenty-first century digital skills. These factors can be grouped into three main streams, which are 1) digital literacy, 2) digital learning and 3) twenty-first century digital skills. These three streams are supported by informational and technological foundations. These results provide research avenues and offer a framework for digital literacy in education
Scan it, buy it, pay it ::customers' psychological contracts as partial employees in retail
No full textPurpose : Self-service technologies (SST) have become more and more pervasive in retail to facilitate autonomous checkout. In this context, customers play an active role and, as such, can be considered as “partial employees.” Partial employees have to perform a wide range of tasks, get rewarded for their work and need to understand the terms of the exchange, all without being subject to a formalized contract. In this research, the authors suggest that partial employees go through a process of organizational socialization that allows them to define the psychological contract they hold with the organization. Design/methodology/approach : In order to investigate the psychological contracts of partial employees, 324 Canadian customers using SST completed an online questionnaire, in which their SST use, psychological contract fulfillment and organizational socialization were measured. Findings : Descriptive analyses highlight that customers as partial employees build a psychological contract with their most frequent retailer, as they perceive not only retailer inducements but also their own contributions. Multiple linear regressions suggest that organizational socialization favors psychological contract fulfillment, but that specific dimensions of organizational socialization are important for employer inducements vs. employee contributions. Moreover, results suggest that the frequency of use of SST as well as the patronage positively predicts psychological contract fulfillment. Originality/value : This research investigates a specific situation of unconventional employment – that of customers as partial employees with organizations. It contributes to the literature on the psychological contract by broadening its application to new relations and to the literature on customer management by reemphasizing the relevance of the psychological contract in this domain
