Home 9/12/2008 NoTrade Solution Lecture 5 Economics 3610 Cornell University Fall 2008 Home Solution with Trade at Foreign's Prices Cloth, QC (yards) 75 50 37.5 25 A U2 U1 B 37.5 50 Home production 75 100 Wheat, QW (bushels) Relative price of cloth in Foreign is PC/PW = 1. Relative price of cloth in Home is PC/PW = 2. Therefore Foreign would want to export their cloth to Home--they can make it for $1 and export it for more than $1. The opposite is true for wheat. Home will export wheat and Foreign will export cloth. Both countries export the good for which they have the comparative advantage. International Trade Equilibrium Two countries are in a trade equilibrium when: the relative price of each good is the same in the two countries the amount of each good that the countries want to trade is equal How Trade Occurs As Home exports wheat, quantity of wheat sold at Home falls. The price of wheat at Home is bid up. More wheat goes into Foreign's market. h i i ' k The price of wheat in Foreign falls. As Foreign exports cloth, the quantity sold in Foreign falls, and the price in Foreign for cloth rises. The price of cloth at Home falls. Characterizing the equilibrium the Determine relative price of wheat or cloth in the trade equilibrium Determine production and consumption in both Home and Foreign 1 9/12/2008 Change in Production The relative price of wheat in the trade equilibrium will be between the notrade price in the two countries. Assume the free trade price of PC/PW is 3/2 the freetrade price of P is 3/2. Between the price of in Home and 1 in Foreign. Text says this is an equilibrium We can now take this price and see how trade changes production and consumption in each country. Home wheat producers can earn more than opp. cost of wheat by selling to Foreign. Home shifts labor resources toward the production of wheat and increases its production of wheat and increases its production. Wages are calculated by the price of the good times its marginal product. Given the information from before, we can calculate the ratio of wages in the two industries Home's workers will want to work in wheat and no cloth will be produced. With trade, Home will be fully specialized in wheat production. wheat production PW MPLW 2 4 8 = = > 1 PC MPLC 3 2 6 Therefore PW MPLW > PC MPLC Wages in wheat > Wages in cloth 2
