✔ 最佳答案
個人認為是這樣(不太肯定)：1.（這題不太肯定）
C）private-owned firms 更加普遍有job promotion “related” to productivity。
我覺得用productivity決定升職是用來增加員工的working incentive的。private-owned firms 裏面決定誰升職的人比public enterprise裏面得更加想去幫公司增加收益，因為私人公司的盈虧可能影響到他們個人的收入，但政府的盈虧就不影響員工的個人收入。
law of demand話price &quantity demanded係成反比。
在這個例子中，假設員工demand的是leisure time,所以“price”(opportunity cost)是salary，“quantity demanded”是leisure time。如果員工想薪金增加（salary增加→price增加 ），他們就會勤力點工作（leisure time減少→quantity demanded減少），那樣公司就可以減低平均成本提高得益。所以用productivity決定升職是用來增加員工的working incentive的，而private-owned firms 就更有心去這樣來增加收益。
2.（這題比較懂）
這題主要跟Alchian's Generalization有關
選擇A是因為有交通費，再計算relative price，就會知道價錢上的差異。
選擇B："per-unit tax" 才會leads to a greater drop in the sales of lower-priced whisky，因為lower-priced whisky和higher-priced whisky 價錢增加的比例不同，令到relative price 不同。但“ad valorem tax ”就不會，因價錢增加的百分比是一樣的。
選擇C：吃ordinary dinners顧客會吃到MUV=P
吃Buffet顧客會吃到MUV=0
選擇D：wear seatbelt會降低駕駛者的危險（超速駕駛的cost ↓)，所以就多點人超速駕駛，以致多點意外發生。
（以上淺見，希望可以幫到你啦！）
