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.
