Vertical Integration in the Value Chain: A Comprehensive Guide

Chapter 12: Vertical Relations in the Value Chain

Boundaries of the Firm

The vertical value chain flows from upstream to downstream as follows:

  1. Acquisition of Raw Materials
  2. Production & Operations
  3. Support Service
  4. Sale of Finished Product
  5. Customer Service

Organizing the vertical chain is crucial to business strategy. Key decisions involve determining which steps to perform internally (make) and which to outsource (buy).

Vertical Integration

Vertical integration involves combining separate stages of the supply chain under single ownership. There are two primary types:

  1. Forward Integration: An upstream firm owns assets of downstream firms.
  2. Backward Integration: A downstream firm owns assets of upstream firms.

Reasons to Make

  • Avoiding Double Marginalization: This occurs when a product passes from an upstream firm (A) to a downstream firm (B) and finally to the consumer, potentially inflating the final price.
  • Lowering Transaction Costs: Internalizing processes can reduce costs associated with market transactions.
  • Avoiding Private Information Leaks: In-house operations can protect sensitive data.
  • Avoiding Hold-Up by Suppliers: Vertical integration can mitigate the risk of suppliers exploiting dependence.

Reasons to Buy

  • Access to Efficient Inputs: Market firms may possess patents or proprietary knowledge enabling lower production costs. They may also achieve economies of scale unattainable by in-house units.
  • Mitigation of Agency Problems: Outsourcing can help avoid internal agency issues that impact costs.

Implications

In the short term, buying is preferable when the combined price of the product and transaction costs is less than the cost of internal production.

Long-term considerations include risks of input shortages, transparency of internal plans, and the dynamic nature of supplier markets.

Contracts: A Tool for External Tasks

Purpose: Contracts outline tasks and remedies for non-performance, aiming to protect against opportunistic behavior. Ideally, they should be comprehensive and grounded in contract law.

Enforcement: Effective enforcement requires verifiable performance, observable actions, and enforceable penalties for breaches.

Incomplete Contracts: In reality, contracts are often incomplete due to factors like bounded rationality, performance assessment difficulties, and information asymmetry.

Contract-Related Problems

  • Property Rights Structure: Issues can arise from unclear property rights specifications. Litigation often serves as a recourse for breaches.
  • Transaction Costs: These include costs associated with implementing exchanges and can be influenced by relation-specific assets.
  • Principal-Agent Problems: These can further escalate transaction costs.

The Make-or-Buy Trade-Off

Benefits of Integration

  • Reduced transaction costs
  • Improved agency efficiency
  • Potential for higher entry barriers due to increased investment costs for competitors

Costs of Integration

  • Potential inefficiencies compared to market specialists
  • Difficulties in achieving least-cost production across the entire supply chain
  • Challenges in product diversification
  • Potential management style conflicts
  • Higher capital requirements

The Make-or-Buy Fallacies

  • Making Assets for Competitive Advantage (When Readily Available): Focus should be on whether making or buying is more efficient, not solely on owning the asset.
  • Outsourcing Eliminates Activity Costs: The key question is comparative efficiency, not just cost elimination.
  • Backward Integration Captures Supplier Profits: Market competition tends to erode excessive profits over time.
  • Backward Integration as Insurance Against High Input Prices: Integrating a risky activity doesn’t necessarily reduce overall risk.
  • Tying Up Distribution Channels to Block Rivals: This strategy is often restricted by antitrust laws.

Alternatives to Vertical Integration: The Make-or-Buy Continuum

Options include:

  • Short-term market transactions
  • Tapered integration
  • Implicit contracts between firms
  • Long-term contracts and collaborative relationships
  • Joint ventures and strategic alliances
  • Partial integration
  • Full integration
