Recently, Wardowski introduced a new concept of contraction and proved a fixed point theorem which generalizes Banach contraction principle. Following this direction of research, in this paper, we ...will present some fixed point results of Hardy-Rogers-type for self-mappings on complete metric spaces or complete ordered metric spaces. Moreover, an example is given to illustrate the usability of the obtained results.
This article reviews the recent advances in the uniqueness and multiplicity of competitive equilibria in models arising in mathematical economics, finance, macroeconomics, and trade.
Opinion leaders are important sources of advice for other consumers. Instagram is the most used platform by opinion leaders in the fashion industry, and this trend is expected to continue in the near ...future. This study aims to identify some key antecedents and consequences of opinion leadership in this context. Our results, based on data collected from 808 followers of a fashion focused Instagram account, suggest that originality and uniqueness are crucial factors if a user is to be perceived as an opinion leader on Instagram. In addition, opinion leadership influences consumer behavioral intentions toward both the influencer (intention to interact in the account and recommend it) and the fashion industry (intention to follow fashion advice posted). Finally, the perceived fit of the account with the consumer's personality strengthens the influence of opinion leadership on the intention to follow published advice. These results have interesting implications for the fashion industry.
•Data from 808 followers of an Instagram account focused on fashion is analyzed.•Originality and uniqueness positively influence opinion leadership on Instagram.•Opinion leadership affects consumers' intention to follow the influencer's advice.•Opinion leadership affects behavioral intentions related to the influencer.•Perceived fit and online interaction propensity act as moderators.
This paper establishes a link between endowments, patience types, and the parameters of the HARA Bernoulli utility function that ensure equilibrium uniqueness in an economy with two goods and two ...impatience types with additive separable preferences. We provide sufficient conditions that guarantee uniqueness of equilibrium for any possible value of \(\gamma\) in the HARA utility function \(\frac{\gamma}{1-\gamma}\left(b+\frac{a}{\gamma}x\right)^{1-\gamma}\). The analysis contributes to the literature on uniqueness in pure exchange economies with two-goods and two agent types and extends the result in 4.
L'industrie de la production indépendante d'énergie renouvelable est incontournable pour améliorer notre résilience et notre sécurité énergétique, ainsi que pour atteindre nos cibles climatiques. ...L'Association québécoise de la production d'énergie renouvelable (AQPER) a mis â profit l'expertise de ses membres pour développer la Feuille de route 2030, qui identifie la contribution des diverses filieres énergétiques québécoises nécessaire â la hausse de la production d'énergie renouvelable pour atteindre les cibles climatiques québécoises. L'électricité n'est toutefois pas la seule forme d'énergie renouvelable a développer pour atteindre nos objectifs. Une question sans solution unique Considérant l'ampleur de nos besoins énergétiques futurs, il n'y a pas de solution unique pour y répondre. Ensuite, que le déploiement de l'ensemble des filiéres est également un outil de résilience pour nos communautés et notre économie ; la production d'énergie indépendante est préte a déployer ses solutions partout au Québec. Cela représente une occasion importante a ne pas manquer pour nos entreprises et nos communautés.
