A multinational organization has multiple divisions that sell their products internally to other divisions When selling internally, which of the following transfer prices would lead to the best decisions for the organization?

The optimal transfer price for an organization is one that promotes goal congruence, meaning that decisions made by divisional managers in their own best interest also serve the best interest of the company as a whole. A market-based transfer price is generally considered the best method when a competitive external market for the product exists. It provides an objective, arm's-length price that reflects the opportunity cost to the selling division of transferring internally rather than selling externally. This encourages the selling division to be efficient and the buying division to make economically sound sourcing decisions, thereby leading to the best outcomes for the entire organization.

A. Full cost: This method provides no profit incentive for the selling division and can pass its inefficiencies on to the buying division, distorting performance evaluation and leading to suboptimal decisions.
B. Full cost plus a markup: The markup is often arbitrary and may not reflect true market conditions or opportunity costs, potentially causing the internal price to be uncompetitive and leading to poor sourcing decisions.
D. Variable cost plus a markup: This approach ignores fixed costs, which can understate the true cost of production. While useful for short-term decisions with excess capacity, it is not sustainable for long-term profitability and decision-making. ---

In Chapter 22, "Management Control Systems, Transfer Pricing, and Multinational Considerations," the authors state, "When the market for the intermediate product is perfectly competitive... the market price is the optimal transfer price because it leads to optimal decisions for the company as a whole." (p. 832).

Chapter 11, "Performance Measurement in Decentralized Organizations," explains that using the market price is the best approach when an outside market exists because it aligns the interests of the divisions with the interests of the overall company, thus promoting goal congruence.

The lecture notes identify the market price as the "ideal transfer price" because it preserves divisional autonomy, incentivizes the selling division to be competitive, and provides the buying division with the correct information to make optimal trade-off and substitution decisions.
