Managers in the fundraising and public sectors face the constant challenge of soliciting donations from a population who may or may not have donated before. Rather than merely asking respondents what they wish to donate, it is standard practice to present a set of suggested amounts – the...

This article aims at discussing the various dimensions of budget allocation decisions made by final consumers. We review the main research and offer a conceptual typology of allocation choices at different levels (time, efforts, product categories, brands…). Then, we make suggestions to carry...

In response to a drop in collected funds, charitable associations have implemented a rigorous approach to the target decisions and communication for fundraising. Prior studies have shown that manipulating the scale of donations influences the collection results. This study was carried out within...

The aim of the paper is to analyze the impact of heterogeneous beliefs in an otherwise standard competitive complete market economy. The construction of a consensus probability belief, as well as a consensus consumer, are shown to be valid modulo an aggregation bias, which takes the form of a...

The article discusses the origins of the U-shaped average cost curve, which is one of the most widely used tools in microeconomic analysis. Its widespread use leads many to consider it as a basic tool, obscuring the fact that the graph of the U-shaped average cost curve is part of a complex...

An F-cone is a pointed and generating convex cone of a real vector space that is the union of a countable family of finite dimensional polyedral convex cones such that each of which is an extremel subset of the subsequent one. In this paper, we study securities markets with countably many...

In several papers, Negishi revisted the foundations of competitition. Sensitive to the Edgeworthian views of exchange but strongly influenced by the law of indifference of Jevons, he tried to reconcile both approaches. The main result of this synthesis is the equivalence between the walrasian...

This research aims to replicate for France the results obtained by Diller and Ivens (2000) in Germany in which it was found that part of the demand is transferred from low price to high price brands. Using a different methodology involving buying intention data towards a private and a national...

We consider exchange economies with a measure space of agents and for which the commodity space is a separable and reflexive Banach lattice. Under assumptions imposing uniform bounds on marginal rates of substitution, positive results on core-Walras equivalence were established in...
