Modelling prices and the reputation of individual named wines

This article develops empirical models to assess the relation between the reputation of an individual named wine and its price. Unrestricted and polynomial distributed lag models are used to assess the impact of past expert quality ratings on the prices of Australian premium wines. Results point to the practical unimportance of current wine quality scores impacting prices and suggest that quality score lag effects up to six years may be important. The largest individual lagged impact of quality on price is estimated to occur at approximately two years, and prices are estimated to increase by more than 10% over six years for a one-point quality score increase. A procedure for identifying potential wine price bargains based on a comparison of price predictions from estimated wine reputation and current quality measures is illustrated. The implications of the findings for wine producers are also discussed.
