In a(n) ______ vertical marketing system, a firm owns and controls all of its supply chain

• A. Contractual
• B. Administered
• C. Independent
• D. Corporate

Answer: (D)

Ownership across the supply chain is the defining feature here: when one company owns and controls multiple levels of the channel—manufacturing, distribution, and retail—it creates a corporate vertical marketing system. This arrangement lets the firm align production, distribution, and marketing decisions, reduce channel conflict, and capture more of the value created at each stage through centralized planning and investment. It also enables tighter integration of branding, pricing, and service standards, leading to a more consistent customer experience. In contract-based systems, coordination comes from contractual agreements with independent firms (like franchises or wholesale-retail contracts), not ownership. In administered systems, coordination arises from the power and influence of a dominant member rather than ownership. In independent systems, channel members operate separately with minimal structural integration and no shared ownership.
