Duopolistic Competition, Taxes, and the Arm's-Length Principle

Numerous (high-tax) countries presume that multinational firms use their transfer-pricing policies to shift profits into countries with lower tax rates. To avoid the corresponding loss in tax revenues, tax authorities develop constantly tightening rules to curb transfer-price distortions. Affected firms include the decision of compliance to these rules into their strategic considerations. In a scenario with arm's-length regulation in two countries, we analyze the transfer-pricing policy of a firm that uses the same transfer price for tax and managerial incentive purposes. Thus, the transfer-pricing policy is driven by three issues: interaction with competitors, minimization of tax burden, and avoidance of punishments. The model shows that tighter transfer-pricing rules may help firms to mitigate competition and to increase their profits and that non-compliance to the arm's-length principle is part of their equilibrium strategy.
