    Buyer Power through Producer's Differentiation

    Cet article montre que des distributeurs peuvent dĂ©cider d'offrir des produits diffĂ©renciĂ©s, non pas pour relĂącher la concurrence horizontale, mais pour accroĂźtre leur pouvoir d'achat vis-Ă -vis de leur fournisseur. Nous analysons un modĂšle simple oĂč deux producteurs offrent des produits diffĂ©renciĂ©s en qualitĂ© Ă  deux distributeurs en activitĂ© sur des marches sĂ©parĂ©s qui ne peuvent offrir qu'un seul produit aux consommateurs. A la premiĂšre Ă©tape du jeu, les distributeurs choisissent quel produit mettre en rayon, puis chaque distributeur et son fournisseur nĂ©gocient sur un contrat de tarif binĂŽme. Enfin, les distributeurs choisissent leur quantitĂ©s. Lorsque les coĂ»ts de production sont convexes, la part des profits joint revenant au distributeur est plus Ă©levĂ©e lorsque les distributeurs choisissent de se diffĂ©rencier. L'origine de la diffĂ©renciation peut donc ĂȘtre uniquement liĂ©e au dĂ©sir des distributeurs d'accroĂźtre leur pouvoir d'achat: via la diffĂ©renciation des fournisseurs, le distributeur obtient une plus large part de profits joints plus faibles. Ce rĂ©sultat est robuste lorsque l'on introduit de la concurrence en aval. Nous mettons en Ă©vidence les consĂ©quences de cette stratĂ©gie de diffĂ©renciation sur le surplus des consommateurs.Puissance d'achat;Gamme de produit;DiffĂ©rentiation des produits

    The purpose of this paper is to make a comparative analysis of the understanding of Saint Ignatius of Loyola’s Spiritual Exercises in two great theologians who influenced theperiod after Vatican Council II in the twentieth century, Karl Rahner (1904–1984) andHans Urs von Balthasar (1905–1988). This analysis aims to identify the image of God asit appears in their respective theological projects, that employing the inductive method,in Rahner’s theological anthropology, and that employing the deductive method, inBalthasar’s theological aesthetics, and to identify how such images of God are involved incontemplative practice according to their respective theological understandings, bothtrying to adapt the Ignatian experience to the contemporary person, each theologian inhis own way. Therefore, this study intends to analyze how the author®s understanding of the Spiritual Exercises is presented within each theological project and then to identifythe similarities and differences between them. Such analysis intends to recognize how these two theologians of great scope understood spirituality first as a part of humanexistence and, in this context, how they understood the knowledge of God as the revela-tion of meaning and the source of new understanding in the search for an authentic life,even given their distinct accents both existential and on the Christian mystical tradition.info:eu-repo/semantics/publishedVersio

    Spirituality and health in pandemic times: lessons from the ancient wisdom

    Get PDF
    The goal of this paper is to analyze how the historical episode of the so-called Plague of Athens between the years 430 and 426 BC seems to have been the first phenomenon classified as an epidemic by Hippocrates, and the historian Thucydides described its cultural, social, political and religious consequences. However, such a crisis generated the need for a new culture, and consequently a new theological mentality, as a cultural driver that made it possible to transform the Asclepiad Sanctuary of Kos into the first hospital in the West to integrate spirituality and science as ways to promote the healing of culture in order to achieve the ideal of health. The adopted method was a semantic analysis of the classic texts that help contextualize the Hippocratic view of the epidemic, spirituality, and health, and how these questions were received by Christianity at the time. The reception of this experience by Christianity, despite suffering some tension, also expands this Greek ideal and constitutes a true heritage of ancient wisdom that can be revisited in the time of the new pandemic, COVID-19. The perspective assumed here is interdisciplinary, putting in dialogue Theology and Health Sciences.info:eu-repo/semantics/publishedVersio

    Revisiting the Income Effect: Gasoline Prices and Grocery Purchases

    Get PDF
    This paper examines the importance of income effects in purchase decisions for every-day products by analyzing the effect of gasoline prices on grocery expenditures. Using detailed scanner data from a large grocery chain as well as data from the Consumer Expenditure Survey (CES), we show that consumers re-allocate their expenditures across and within food-consumption categories in order to offset necessary increases in gasoline expenditures when gasoline prices rise. We show that gasoline expenditures rise one-for-one with gasoline prices, consumers substitute away from food-away-from-home and towards groceries in order to partially offset their increased expenditures on gasoline, and that within grocery category, consumers substitute away from regular shelf-price products and towards promotional items in order to save money on overall grocery expenditures. On average, consumers are able to decrease the net price paid per grocery item by 5-11% in response to a 100% increase in gasoline prices. Our results show that consumers respond to permanent changes in income from gasoline prices by substituting towards lower-cost food at the grocery store and lower priced items within grocery category. The substitution away from full-priced items towards sale items has implications for microeconomic discrete-choice demand models as well as for macroeconomic inflation measures that typically do not incorporate frequently changing promotional prices.
