Introduction

The Grand Historian records: Within a vast empire, provinces trade with each other — grain from the plains for iron from the mountains, silk from the south for horses from the north. The price at which these internal transactions occur matters enormously. Set it too high, and the buying province suffers while the selling province prospers at the empire’s expense. Set it too low, and the reverse occurs. Set it wrong enough, and provincial governors make decisions that optimize their own reports while destroying value for the empire as a whole.

Horngren (Chapter 22) presents transfer pricing as one of the most challenging topics in management accounting — a point where cost accounting, economics, organizational behavior, and tax law collide.

Why Transfer Pricing Matters

In a decentralized organization, divisions are evaluated as profit or investment centers. When Division A sells to Division B, the transfer price simultaneously becomes:

• Revenue for the selling division (increasing its profit)
• Cost for the buying division (decreasing its profit)
• A wash for the overall corporation (internal revenue = internal cost)

The danger: a transfer price that maximizes one division’s reported profit may cause the other division to make suboptimal decisions — buying from outside when internal sourcing is cheaper for the company, or vice versa.

The General Guideline

Horngren’s general transfer pricing rule:

Minimum Transfer Price = Incremental Cost per Unit + Opportunity Cost per Unit

• Incremental cost: The variable cost of producing and transferring the goods.
• Opportunity cost: The contribution margin forgone by not selling externally. If the selling division has excess capacity and no external market, opportunity cost is zero.

Transfer Pricing Methods

1. Market-Based Transfer Price

Set the transfer price equal to the external market price for identical goods. This is the theoretically ideal method when a competitive external market exists:

• Promotes goal congruence — both divisions face the same price as the market.
• Provides a clear benchmark for divisional performance.
• Limitations: requires a competitive market for the intermediate product; market price may not exist for specialized or proprietary goods.

2. Cost-Based Transfer Price

Set the transfer price based on the selling division’s cost — variable cost, full cost, or cost-plus-markup:

• Variable cost: Encourages the buying division to purchase internally but gives the selling division zero contribution margin — undermining its profit center status.
• Full cost: Includes fixed cost allocation, which may cause the buying division to reject internally priced goods that are actually cheaper than external alternatives at the margin.
• Cost-plus: Adds a markup to ensure the selling division earns a profit, but the markup is arbitrary.

太史公曰：Cost-based transfer prices have a fatal flaw — they transfer the selling division’s inefficiencies to the buying division. If the seller is wasteful, the buyer pays the price of that waste in higher transfer costs. There is no market discipline to constrain the seller’s costs.

3. Negotiated Transfer Price

Divisions negotiate the price between themselves, constrained by the general guideline. This preserves divisional autonomy but can consume management time and create internal conflict. It works best when both divisions have outside alternatives.

International Transfer Pricing

When divisions in different countries trade with each other, transfer pricing acquires a tax dimension. By shifting profits to low-tax jurisdictions through artificially high or low transfer prices, multinational corporations can reduce their global tax burden.

Tax authorities worldwide combat this through arm’s-length pricing rules: transfer prices must approximate what unrelated parties would charge in comparable transactions. The OECD Transfer Pricing Guidelines provide the international framework, and penalties for non-compliance are severe.

Key Takeaways

• Transfer prices simultaneously affect selling division revenue and buying division cost — they must promote goal congruence.
• The general guideline: Minimum TP = Incremental cost + Opportunity cost of the selling division.
• Market-based prices are ideal when competitive markets exist; cost-based prices transfer inefficiencies; negotiated prices preserve autonomy.
• International transfer pricing has significant tax implications — arm’s-length rules apply.
• No single method is perfect — the best approach depends on market conditions, organizational structure, and strategic objectives.
