This paper studies the determinants of economies of scope and quantifies their impact on the extensive and intensive product margins in retail. We use a framework based on a multiproduct technology to model stores’ incentives to expand product variety. Using novel Swedish data on product categories and stores, we find that high-productivity stores offer more product categories and sell more products of all categories. Stores with high-demand shocks specialize in fewer product categories and sell more products of top-selling categories. Policy simulations of regional programs that target the determinants of economies of scope show that investment subsidies and mentoring support for low-productivity stores increase the number of product categories and sales per product category, especially benefiting stores in rural markets.
