8. David Ricardo Ricky Ricardo Songs24 Cookies68 Who has the absolute advantage in writing songs? Who has the absolute advantage in baking cookies?

9. If one person/country has the absolute advantage for BOTH goods, then you must find comparative advantage

10. 1 song costs David 3 cookies 1 song costs Ricky 2 cookies Ricky can write songs more cheaply, so Ricky should write songs and David should bake cookies Ricky has the “comparative advantage” in writing songs David has the “comparative advantage” in baking cookies Songs Cookies 2 6 4 8 1 3 1 2  Simplify 

11. Ricky should write songs, David should bake cookies, and they should trade songs for cookies. BUT, how many cookies should one song equal?

12. When Ricky writes one song, he gives up the opportunity of baking 2 cookies, so he wants to sell his songs for MORE than 2 cookies to make a profit David could write a song for the cost of 3 cookies, so he wants to buy a song for LESS than 3 cookies to save 3 cookies > 1 song > 2 cookies 1 song = 2.5 cookies To find how much one cookie should equal, find the reciprocal of 2.5 1 cookie = 2/5 song

13. If Ricky writes 4 songs and trades those for cookies, then he can have either 4 songs OR 10 cookies If David bakes cookies and trades those for songs, then he can have either 6 cookies OR 2.4 songs Before Trade: After Trade:
