In theoretical literature it is common to make the assumption that in a multi‐country, multi‐good world, the direction of trade (import and export by commodity) is predetermined and fixed for each good for each country. We consider a simple three‐country, three‐good, pure‐exchange model with CES preferences. We compute free trade competitive equilibria, three‐country non‐cooperative Nash equilibria, and customs union equilibria for randomised parameterizations, and find that trade pattern changes between free trade and customs union equilibria in around 35% of cases.
