The market value for product attribute improvements under price personalization

Personalization of the marketing mix is a topic of much interest to marketing academics and practitioners. Using discrete choice demand theory, we investigate the aggregate market value for product attribute improvements when firms are engaged in personalized pricing. Our results provide a theoretically grounded rule for how to aggregate consumer valuations to assess the overall profitability of attribute improvements under price personalization. Under common pricing, each consumer contributes the same margin. Profitability of an attribute improvement is thus driven by inducing more consumers to buy. Consumers with high choice probabilities are given less weight in the market valuation under common pricing as they are less responsive to attribute improvements. Under personalized pricing, profitability of an attribute improvement is driven by extraction of consumer surplus from high valuation consumers. Consumers with higher valuations, and consequently higher choice probabilities, are given more weight in the market valuation under personalized pricing. Since individual consumers play a more central role in the market valuation under personalized pricing, estimation of consumer-level valuations is of increased importance. Under common pricing, the market valuation for an attribute improvement is robust to extreme estimates of the consumer-level valuations. Through our theoretical and empirical analyses, we demonstrate that this robustness does not hold under personalized pricing.
