This paper investigates whether an e-tailer should act as a platform and offer customers the product of a seller who can reach customers only through the e-tailer, and if so, what type of contract to offer the seller: a proportional commission based on revenue or a fixed fee per unit sold. The e-tailer also chooses the product line design: offer only her own product, offer only the outside seller's product, or offer both her own product and the seller's product. Intuitively, when the e-tailer's product outperforms the seller's product in terms of value-to-cost ratio, the e-tailer should not offer the seller's product. However, non-intuitively, we also identify conditions in which the e-tailer remains better off not opening her platform to the seller even though the seller's value-to-cost ratio is higher than the e-tailer's and show how these conditions depends also on the consumers valuations. Regarding the type of contract to offer the seller, we find that most of the time, a proportional commission based on revenue is the best contract, guaranteeing the highest e-tailer profit. However, this is not always the case since there are situations when a fixed fee contract reduces the potential of internal competition.

Background: Chile's Food Labelling Law was implemented in three phases with increasingly stricter limits. After initial implementation, sugars and sodium decreased in packaged foods, with no significant changes for saturated fats. It is unclear whether full implementation is linked with further reformulation or if producers reversed changes due to consumers' preferences.

Small and medium-sized enterprises (SMEs) can gain a competitive advantage by implementing business model innovation (BMI), which is characterized as irreversible changes to a company's business model. However, BMI is often associated with high risk, uncertainty, and ambiguity.
