Extending the double jeopardy and duplication of purchase laws to the wine market

Extending the double jeopardy and duplication of purchase laws to the wine market PurposeThis study aims to understand the market structure and explore the applicability of recognised generalisations to a European wine retail market. The study considers whether brands in European wine retailing follow the established double jeopardy and duplication of purchase laws, with the aim of investigating their limits so as to identify where market partitions are evident.Design/methodology/approachThe researchers conducted a cross-purchasing analysis within the wine category over a 12-month period, using a customer panel of n = 25,000 across a chain of independent retail stores in an English-speaking European country. Analysis was conducted across purchases of the top 20 wine brands.FindingsConsumer wine repurchase results confirmed a double jeopardy pattern. These consumers’ wine repurchasing behaviour from other top-20 wine brands could have generally been predicted in line with the duplication of purchase law.

Such exceptions illustrate that consumer purchase patterns can deviate from predictions, for a small number of brands in a consumer goods category than would be expected given duplication of purchase law norms. Such anomalies to empirical generalisations help demonstrate boundary conditions and lead further research on the market conditions required for such anomalies to be evident.

Abstract

PurposeThis study aims to understand the market structure and explore the applicability of recognised generalisations to a European wine retail market. The study considers whether brands in European wine retailing follow the established double jeopardy and duplication of purchase laws, with the aim of investigating their limits so as to identify where market partitions are evident.Design/methodology/approachThe researchers conducted a cross-purchasing analysis within the wine category over a 12-month period, using a customer panel of n = 25,000 across a chain of independent retail stores in an English-speaking European country. Analysis was conducted across purchases of the top 20 wine brands.FindingsConsumer wine repurchase results confirmed a double jeopardy pattern. These consumers’ wine repurchasing behaviour from other top-20 wine brands could have generally been predicted in line with the duplication of purchase law. However, a small number of exceptions to these patterns were identified, suggesting the existence of market partitions.Research limitations/implicationsIn this study, market partitions were evident for selected brands, a wine region and a common grape variety, Sauvignon blanc. Such exceptions illustrate that consumer purchase patterns can deviate from predictions, for a small number of brands in a consumer goods category than would be expected given duplication of purchase law norms. Such anomalies to empirical generalisations help demonstrate boundary conditions and lead further research on the market conditions required for such anomalies to be evident. Implications suggest that further research should be conducted on the product features creating market partitions.Practical implicationsThe findings suggest that regional wines can appeal to a more clearly partitioned customer group within the clientele, but that substitution is noted among brands within regions.Originality/valueTo the best of the authors’ knowledge, this is the first study to use a large sample consumer database to determine the generalisability of two well-established empirical generalisations: the double jeopardy and duplication of purchase laws, to the wine retail market. Knowing these are applicable to the wine retail markets allows wine producers and retailers to predict expected repurchase and cross-purchasing norms.
