We evaluate the claim that bottle size formats signal quality changes by performing a controlled laboratory experiment in which we simultaneously auction two different sweet wines: a pomegranate wine and a grape wine. We vary the size of the bottle from 500 mL to 750 mL between participants, but we keep the amount of wine constant across the bottle sizes. We also explore the effect of expectations for the wines, blind tasting, and information about wine attributes on people's willingness to pay (WTP). For both wines, we find evidence consistent with diminishing marginal utility; for the pomegranate wine, we find a premium for the smaller bottle size, which is consistent with changes in the wine's perceived quality. We also find that information is adequate in offsetting the negative effect of the tasting treatment. (JEL Classifications: C23, C24, C91, D12, M31)

Although they have often been found to be technically inefficient, cooperatives not only have survived in the wine industry but continue to play major roles in most European countries. Because the specific advantages of their “organizational architecture” (resource pooling and decentralization) seem to outweigh the disadvantages (vaguely defined property rights and high monitoring costs), this paper discusses organizational measures to improve the performance of cooperatives by addressing three different aspects of “organizational design” (managing entry and exit, motivating members, and investing in corporate culture).

This paper examines the strong version of the law of one price (LOOP) on the auction market for fine wine. We draw on worldwide auction prices from eight auction houses,1 covering the time period from 2000 to 2012. Employing a hedonic approach, we find significant price premiums in particular in Hong Kong and between auction companies (independent of their locations). The price premiums by far exceed the expected transaction costs, casting doubt on the existence of the strong version of LOOP in the fine wine market. Our results suggest that heterogeneity in buyer preferences may crucially contribute to the observed price dispersion. In particular, although wines suspected of being counterfeits are sold at discounts in Western markets, they fetch price premiums in Hong Kong. (JEL Classifications: Q14, G11)

In this paper, we compare three ranking methods in wine tasting in terms of their respective accuracy levels. The first two are the original-score average and rank average, which are conventional methods in practice. The third is a relatively new ranking method called Shapley ranking. It is a game-theory-based ranking method, whereby judges are required not to rank order or score all the wines but only to choose a subset that they find meritorious. A simulation study is designed, wherein the data-generating scheme mimics how the real wine-tasting data are produced. We also consider two criteria in the comparison: the squared-error loss, which is a suitable measure when accurate ranking of all wines is of interest; and the percentile loss, which only considers whether the wines are correctly put in a certain subset. The main conclusion from our study is that the ranking based on score average is generally more accurate than that based on rank average. Shapley ranking, with the consideration that it puts less burden on judges in wine tasting, may outperform the other methods in certain conditions. (JEL Classifications: C11, C15, D72, D81)

Competition medals are one of the most readily available sources of expert opinion to wine consumers, yet the “expertise” of competition judges and efficacy of medals have been questioned in the literature. This paper reevaluates the relevance of gold medals using data from ten competitions and scores from two leading wine publications. The analysis begins by exploring differences in gold medal award rates across competitions while holding wine quality constant through paired comparisons, which are found to be substantial. Next, the relevance of gold medals as indicators of wine quality is assessed, using the average scores from Wine Enthusiast and Wine Spectator as surrogates for quality. By itself, knowledge that a wine is a gold medal winner appears to have little relevance, as these wines do not score significantly higher than other medal winners. However, evidence suggests that golds from some competitions may be more relevant than others. (JEL Classifications: L15, L66)

The objective of this article is to estimate the spatial structure of the collective economic conceptualization of strategic actions by cidermakers in Québec. It employs group concept mapping, a mixed methods–based approach. Given the limited research on the economic conceptualization of horizontal coordination for guiding collective strategic action orientations, this contribution is threefold: methodological, empirical, and practical. Methodologically, the results show the perspective of horizontally coordinated cidermakers and use statistical estimates and retroduction as an inference mode to produce and structure the concept map. Empirically, the spatial economic conceptualization consists of a concept map with seven strategic action clusters organized around the notions of product supply and demand and highlights tensions between individual and collective strategic actions. Practically, measures of relative importance and relative feasibility are obtained for each cluster on the map, and implications are discussed. (JEL Classifications: D02, L23, L26, L66, Q18)

Mid-Atlantic wine consumers participated in an Internet survey to determine which of three attributes (retail base prices, Botrytis cinerea [bunch rot] control measure, or weed-control strategy) and attribute levels (e.g., a retail base price of $12, $16, $22, or $26) were the most important factors in their decisions to purchase 750mL glass bottles of wine. Conjoint analysis was used to calculate average importance for the three attributes. Based on these calculations, the base retail price attribute had the greatest impact on participants’ decision to purchase the wine (57.40%), followed by bunch rot control measure (20.76%) and weed control strategy (21.49%). Participants were also asked to indicate how interested (not at all interested to extremely interested) they were in purchasing wines produced from grapes grown using minimal pesticides or with cover crops to control weeds. Separate conjoint analyses were then performed based on participants’ level of interest in the two sustainable production methods. In both instances, the average importance values for retail base price were still higher than the values for either bunch rot or weed control strategies. Average importance values for price were lower for participants who responded that they were “very” or “extremely interested” in purchasing wine produced with minimal pesticides or with cover crops than for participants who were “not all interested” in purchasing such wines.

This paper examines the evolution of champagne prices in New York City from 1948 to 2013 by determining how many hours one must work, using after-tax income, to purchase a bottle of champagne. Each of the three brands analyzed—Bollinger, Louis Roederer, and Moët & Chandon—was divided into three tiers of nonvintage, vintage, and flagship champagne. The results indicated that all income groups worked fewer hours for entry-level nonvintage bottles of champagne, whereas the number of hours required to purchase flagship bottles generally increased.
