[International Trade] WEEK8(1)

Summary

Key Points

• The video covers exercises one through five, focusing on tariffs and import quotas as preparation for a midterm exam. 1:01
• Exercise five will synthesize these concepts by illustrating the deadweight loss created by tariffs in a single diagram. 2:12
• The video assumes a small open economy with a perfectly competitive market and no transportation costs, simplifying calculations. 3:34
• Exercise one demonstrates how a tariff increases the domestic price, boosts domestic production, and reduces domestic consumption. 5:55
• Key tools used include the relationship between domestic and world prices (with and without tariffs), the definition of imports (consumption minus production), and the concept of a binding quota. 5:55
• An import quota is binding only when it restricts imports below the level that would occur under free trade. 6:16
• A tariff's revenue is calculated by multiplying the tariff per unit by the quantity of imports *after* the tariff is imposed. 12:17
• The decrease in imports due to a tariff results from both increased domestic production and decreased domestic consumption. 13:36
• A binding import quota leads to a higher domestic price, increased domestic production, and decreased domestic consumption, similar to a tariff. 14:18
• Unlike a tariff, a binding import quota does not generate government revenue; instead, it creates import quota rents for license holders. 21:32
