Hedonic Price Functions and Wine Price Determinants: A Review of Empirical Research

Abstract The objective of this paper is to present a descriptive review of all the studies published on wine price determinants. The selection process has been carefully designed to assure that we cover the complete literature of hedonic price functions and wine price determinants. Because of the heterogeneity among these studies, the objective was to classify all the determinants in clusters related to geographical and agricultural factors, time horizon, public information and, supply factors (production costs and volume of production). For this review, we have identified a list of 117 papers published on price determinants over the period 1993 to 2018.
