Abstract

[eng] Champagne is a product whose quality is difficult to evaluate, even a posteriori, by the consumer. Firms exploit this particularity and invest in reputation either by producing a wine of high quality or by means of public recognition through advertising. Thus, it is optimal for a producer to invest either entirely in quality or entirely in public recognition. We will demonstrate that these choices of pure strategy constitute a stable evolutionary equilibrium in the context of a polymorphic finite population. This conclusion is confirmed by an econometric study applied to the high-quality segment of the Champagne market. [fre] Le Champagne est un bien de qualité difficilement observable, même ex post par le consommateur. Les entreprises exploitent cette particularité et investissent en réputation soit par le biais de la qualité, soit par celui de la notoriété (via la publicité). Ainsi, il est optimal pour un producteur d'investir exclusivement en qualité ou exclusivement en notoriété. Nous montrons que ces choix stratégiques constituent un équilibre évolutionniste stable dans le cadre d'une population polymorphe finie. Ce résultat est confirmé par une étude économétrique appliquée au marché du vin de Champagne.
