老師，我還想問長遠(yuǎn)來看，完全競爭，壟斷競爭的economic profit都會(huì)變成0，壟斷不會(huì)，那寡頭的economic profit呢？
老師，我想問為什么economic profit是來自于(P-ATC)*Q 我覺得這個(gè)更像是accounting profit誒
第一張圖，為什么AR和MR會(huì)隨著Q增加，變小？第二張圖里的紅框里的話，理解不了，怎么斷句，怎么翻譯？我從公式推導(dǎo)過程中理解，MR=P+Q乘以需求曲線的斜率，那這句話里的adjustment和equalto,怎么理解？
講課中一直提到利率變化會(huì)導(dǎo)致融資成本變化，進(jìn)而導(dǎo)致投資的增減；但利率變化也體現(xiàn)了投資收益率的變化，比如利率上升，投資收益率就會(huì)上升，因此就會(huì)增加投資，這樣理解為何不對(duì)？謝謝。
normal利潤數(shù)值上等于隱形成本對(duì)嗎
紅框里這句話怎么理解？
利率下降，則投機(jī)性貨幣需求上升，是反向關(guān)系。為什么不能理解為利率下降，則投機(jī)產(chǎn)生的收益率下降，則減少投資，所以是正向關(guān)系？謝謝。
這個(gè)圖的拐折能看懂 但這個(gè)A和B還有這個(gè)MR1和MR2看不懂，如果恰好MC落在A和B之間就沒辦法確定利潤最大化的那個(gè)點(diǎn)，這句也不懂。
這里的MR是怎么得出的，為什么會(huì)在這個(gè)位置。
這里的MR是怎么得出來的,為什么會(huì)在這個(gè)位置.
老師好，請(qǐng)問無差異曲線和預(yù)算線的內(nèi)容是被新大綱刪掉了嗎，我看到講義上還有一點(diǎn)影子，但老師沒講
老師，請(qǐng)講解一下這題，謝謝The degree of credibility that a central bank is afforded by economic agents is important because: A they are the lender of last resort. B their targets can become self-fulfilling prophecies. C they are the monopolistic suppliers of the currency
在這道題里p(AB)和P(B/A)有什么區(qū)別,答案為什么不是P(A)=3/4,P(B)=2/3.最終為P(A)*P(B)=1/2?
老師，請(qǐng)講解一下這題，謝謝。 Which of the following is most likely to increase after an increase in aggregate real personal income? A Equity prices B Building permits for new private housing units C The ratio of consumer installment debt to income
老師，請(qǐng)講解一下這題，謝謝If relative to prior values of their respective indicators, the inventory–sales ratio has risen, unit labor cost is stable, and real personal income has decreased, it is most likely that a peak in the business cycle: A has occurred. B is just about to occur. C will occur sometime in the future.
