The question says : The price ceiling is set at "the market price under the subsidy" This actually refers to the eqm price when the subsidy is in place. It is indicated as P1 in the marking scheme but it didn't draw a solid line to represent the ceiling. Try drawing one yourself on paper and do it again. It'll make things clearer. Note that If there were no price ceiling at P1, the current price would have been at the level where D intersects S1, which is not what is shown in the answer. So, the marking is correct but its presentation is... hard to understand. What exercise is this ? On another note , both a subsidy and a price ceiling keeps the price level low, both can do that. But the question tries to investigate the effect on TSS(=CS+PS) of each of them. The conclusion is, of course, TSS is greater when a subsidy is used, rather than a ceiling. I hope my interpretation helps UID382893 帖子172 精華0 積分5 閱讀權限10 在線時間49 小時 註冊時間2015-7-24 最後登錄2018-11-8  查看詳細資料 TOP
