Market and Product Diversification: The Evidence From Retailing

This study explored the number of international regions in which retailers operate, the assortment of product categories they offer their customers, and the effects of these market and product category diversification strategies on retail sales volumes. The analysis used sales data about 246 global large-scale retail stores from diverse industries and countries of origin. We found that both strategies have positive effects on retail sales volumes. The two strategies interact such that the positive effect of market expansion on retail sales volumes is larger for retailers who also follow a strategy of greater product category diversity.
