Description
ECO1104 Sep. 26 , 2013 YUJIE YI #7038840  But would rancher accept such a trade?  In autarky, rancher has to give up 1 kg of meat for 2 kg potatoes - A1-for-2 tradeoff (meat for potatoes) [Initial Output]  Might start producing 12 kg of meat and 24 kg potatoes  With free trade, rancher can: - Move to producing 12 kg potatoes and 18 kg meat - Exchange 5 kg of meat for 15 more kg of potatoes  Note the [gain 3 give up 1] tradeoff rather than the [gain 2 give up 1] tradeoff; its now more favourable - End up with 13 kg of meat and 27 kg of potatoes for a net gain of +1 kg meat and +3 kg potatoes [Final Consumption]  Both parties are made better off (can consume more) by specialization and trade at the rate of 3 kg of potatoes for 1 kg of meat, even though the rancher is more efficient in the production of both goods - In other words, the rancher has the absolute advantage in the production of both goods Chapter 4 The Market Forces of Supply and Demand  Another economic model - Considered “the bread and butter” of microeconomics  Purpose: to analyze the allocation of the production of goods and services across industries of the economy - It responds to the Q question.
