This paper investigates the Rybczynski theorem, the Stolper-Samuelson theorem, and the Heckscher-Ohlin theorem in a two-factor vertical production chain model of trade. For this purpose, capital is introduced into the model of Yano and Dei [Yano, M., & Dei, F. (2003). Trade, vertical production chain, and competition policy. Review of International Economics, 11(2), 237-252.]. A primary analytic device is the economy-wide production curve. This Curve is derived under autarky and free trade, respectively.
