Abstract

This paper considers a multiproduct corporation that adopts consumer-friendly activities and cooperates with single plant firms for improving welfare. Comparing competition and (full or partial) cooperation, we show that full cooperation is socially beneficial if products are strong complements, whereas partial cooperation with a higher consumer-friendly activities is beneficial if products are substitutes. We also examine a sequential choice game of endogenous cooperation in which the multiproduct corporation can induce cooperation and show that our findings are supportive at equilibrium. We finally compare different ownerships of the single plant firms and find that foreign ownership decreases the benefits of cooperation. Therefore, a cooperation with multiproduct corporation should be accompanied with active governmental guideline for promoting consumer friendly activities.
