[AL ECON] Micro 問題
"Due to the rising rent, our shop has to increase the prices." Explain whether you agree with the above argument made by a shopkeeper who rents a shop in a well-known shopping mall in Causeway Bay.我都唔係好清楚 rent 係指 anticipated income 定係租金…
我就假定咗 rent 係租金
如果個租金上升，條 AC curve 向上拉
個 shop 賺少咗 rent
不過因為 MC MR 不變，所以 P 同 Q 無變
所以 shop keeper 句 argument 係 invalid
咁樣答有無問題？
另外，可唔可以話佢因為 price 變所以個 rent 變？
呢句我就諗咗好耐都諗唔到點樣 P 變令個租金變
唔該

Rent 係 economics sense 只係當 TR-TVC 的 Surplus
而 rental value 係 fc
一 make 左個 decision
就irrecoverable--->sunk cost
short run 唔睇 fc
只睇MC/AVC
所以唔成加價理由
如果加租就令成本上漲
咁點解唔係有 give up 同 accept 個 new contract 的程況下而 give up? 原來係咁 :L 唔該晒
另外仲有一題
Suppose there are two types of factors of production namely, labour and land only, and all markets are price-taking. Assume that the quantity of land is fixed at 1 square km, and labour is variable.
Suppose the quantity of land increases to 2 square km, will the worker be better offor worse off?
因為所有 market 係 price taking，所以 factor market 都係 price taking >> 個 firm's faced supply 係打橫
而因為多咗一塊地，要請多啲人先至可以 fully utilize the resources，個 D = MRP curve 向右 shift
個 quantity of labour 就升，不過人工就無變
所以唔係 better off / worse off
returns of fixed factor 同 returns of labour 就大咗
咁樣有無問題？
