Document Summary

Econ 20a lecture 3: production possibility frontier and gains from trade. The slope is constant: every worker in the economy has the same level of skills. No resource specialization: point a to b, opportunity cost=(300-400)/(2000- 1000, oc=-100/1000, oc = -0. 1, point c to d: We will consider the case of trade between two countries: concepts used: It takes 100 labor hours to produce one computer. It takes 125 labor hours to produce one computer. Japan uses 125 labor hours to produce 1 computer: the u. s. has absolute advantage in wheat production, u. s. takes 10 labor hours to produce 1 ton of wheat. Us has comparative advantage in wheat production: comparative advantage: the ability to produce a good at a lower opportunity cost than another producer (us can make wheat cheaper than china can make wheat) Japan has lower opportunity cost of production of computers.
