The Ricardian model of international trade makes predictions about actual international trade flows that O A. are supported without qualification by the empirical evidence. O B. cannot be evaluated with empirical evidence. O C. are supported with qualification by the empirical evidence. O D. are contradicted by the empirical evidence.The gure to the light illustrates The causes and eitects of international labor mobilityr between two countries, Home and Foreign (*i. The horizontal axis represents The total world labor force. The workers employed in Home are measured from the left, the workers employed in Foreign from the ght The left vertical axis shows the marginal product of labor in Home; The right vertical axis shows the marginal product of labor in Foreign. Suppose the initial allocation of labor has UL1 workers in Home and [1'11 workers in Foreign. Given this initial allocation, labor can be expected to O A. migrate from Foreign to Home. 0 B. remain situated where it currently resides. 0 C. migrate from Home to Foreign. D D. migrate toward the higher nominal wage. From the perspective ot the world economy. this migration oi labor is desirable since 0 A. total world output rises by DAE. O B.
