Institutional quality significantly influences international trade patterns. This paper explores how institutional differences affect trade outcomes and factor prices. It presents two models: the Ricardian view, where institutions are treated as productivity differences, and the Grossman-Hart-Moore view, which considers institutional quality as affecting contract enforcement and property rights. The study shows that better institutions in the North lead to a pattern of comparative advantage, with the North gaining more from trade than the South. Factor prices may diverge, with labor in the North benefiting and capital in the South gaining. The paper also provides empirical evidence showing that institutional differences are important determinants of trade flows. The results suggest that trade can improve institutional quality, as countries compete to capture advantageous sectors. The analysis highlights that institutional quality affects trade outcomes, with the South potentially losing from trade if institutions are weak. The paper concludes that institutional differences are a key determinant of trade patterns, and that trade can lead to institutional improvement.Institutional quality significantly influences international trade patterns.
