This paper presents a methodology that solves the global newsvendors problem. It determines the optimal transfer price and the optimal order level of a product at the secondary market simultaneously. The optimal transfer pricing in the global supply chain management is a critical issue, along with quotas, trade barriers, duty drawbacks, etc., related to international trade. Different transfer prices result in significantly different global total after-tax profits for multinational corporations. The optimal order level, traditionally, has also been an important topic in the global newsvendors problem. The methodology proposed in this study finds both the optimal order level and the optimal transfer price iteratively.
