Surplus是剩余的含義，在CFA一級考試知識中Consumer Surplus這個詞也是考生需要掌握的，那這個詞的含義是什么意思？CFA考試中這個題是概念題還是計算題呢？

Consumer Surplus是消費者剩余，消費者愿意支付的錢減去消費者實際支付的錢，是買方參與到特定市場中得到的凈收益。我們一起看看CFA考試中的考試題是怎么出題的！

The monthly demand curve for playing tennis at a particular club is given by the following equation: P Tennis Match= 9 – 0.20 × Q Tennis Match. The club currently charges members $4.00 to play a match but is considering adding a membership fee. If the club continues to charge the same per play charge the most that it will be able to charge as a membership fee is closest to:

A $40.00.

B $162.50.

C $62.50.

【答案】：C

解析：當每次打臺球的價格不變，收取的會員費為消費者剩余部分，即采取一級價格歧視。先寫出需求函數(shù)：Q=45-5P，P=4時，Q=25；Q=0時，P=9。則消費者剩余對應的三角形面積=1/2*（9-4）*25=62.5

所以說在CFA考試中Consumer Surplus是道計算題，考生在備考CFA考試需要做題的話，這邊有CFA題庫可以幫助你學習CFA知識，有需要可以在線咨詢我們老師獲取相關的資料哦！
