On the Consumer Value of Diversity: An Application to Italian Fish
从概念和实证上研究了多样性的消费者价值，提出基于效益函数的度量方法，并应用于意大利鱼类消费，发现互补性和凸性效应共同影响多样性价值，且该价值随商品组合动态变化。
This article investigates the consumer value of diversity both conceptually and empirically. It proposes a measure of diversity value based on a benefit function. It shows that the consumer value of diversity can arise from complementarity and/or convexity effects among consumer goods. The usefulness of the approach is illustrated by an application to fish in Italy. The investigation illustrates the role played by both convexity and complementarity in the valuation of diversity. The empirical evidence shows the importance of dynamics. It also documents how the value of diversity varies depending on the bundles considered.
