Unformatted text preview: -Model predicts pervasive specialization. One country (or perhaps both) specializes in production when allowed to trade. Move forward to look for a more complete model of trade. PPF is concave from the origin. What are the implications of a concave PPF?-Slope of the PPF is not constant.-The opportunity cost of producing good x or y increases as more of that good is produced. -Concave PPF means Increasing Opportunity Cost. What are the implications of increasing opportunity cost?-Assume Px/Py = 1-Economy is producing at point A where slope of PPF = -1/4 -To produce one more unit of x we must give up 1/4 unit of y. -Better to produce one more x than to stay at point A.-Continue to produce good x until opportunity cost yx > Px/Py. -Therefore, equilibrium is where the absolute value of the opportunity cost (slope of PPF) of x is equal to the price of x in terms of y....
