| danlan | For U.S.A, Food -4*2, Clothing 12*2 For Japan, Food 3*3, Clothing -6*3 Food -4*2+3*3=1, Clothing 12*2-6*3=6 |
| sevaa1 | Rationale for this problem: It asks per units of output per work day. Read from the table: that's how much one worker produces per day. I.e. One worker produces 3 units of food per day for Japan. So, if we transfer 3 workers to food, they will produce 3*3 = 9 units more altogether. Apply the same logic to all the transactions and take the difference. - you'll get the right answer. |
| Smiley225 | Good1 sevaa1. |

| shann680 | Not a very clear question. Output per work day does not give the same meaning as output per worker per day. |
| something | Good answer, but not a very clear question. |
| gclafort | I did it like this Food: +9 (3x3) -8 (-2x4) = 1 Clothing: -18 (-3x6)+ 24 (2x12) = 9 |
| chesschh | The graph should say that the output is per worker per day. With this, the answer should be simple... CLOTHING: US increases by 24 units, Japan decreases by 18 units. Resulting in a total 6 units gain. FOOD: US decreases by 8 units; Japan increases by 9 units. Resulting in a total 1 unit increase |
| Inaganti6 | Work vs Worker. critical error in question statement. This is not the kind of question quality I expect for $100. Seriously, we're studying for the CFA here and I didn't encounter any amateur mistakes like this even when I was in high school studying for the SAT. |
| choas69 | i found a pattern in this example and another example please confirm, the total output expansion is the difference between the two countries in specific market. 4-3 = 1 increase in food < jpn has comparative adv > 12-6=6 increase in cloth < US has comparative adv > the same pattern was in my text book. |
