為什么影響AS曲線的因素中，公司稅收只是影響短期AS曲線？
18 In an industry comprised of three companies, which are small-scale manufacturers of an easily replicable product unprotected by brand recognition or patents, the most representative model of company behavior is: A oligopoly. B perfect competition. C monopolistic competition. 為什么不選C？
6 Companies most likely have a well-defined supply function when the market structure is: A oligopoly. B perfect competition. C monopolistic competition. 什么叫well-defined supply function?為什么只有完全競(jìng)爭(zhēng)市場(chǎng)是well-defined supply function?其中3種為什么不是？
25 The short-term shutdown point of production for a firm operating under perfect competition will most likely occur when: A price is equal to average total cost. B marginal revenue is equal to marginal cost. C marginal revenue is equal to average variable costs. 這一題C選項(xiàng)MR=AVC是短期關(guān)停點(diǎn)，基礎(chǔ)課講的是AR=AVC，是因?yàn)樵谕耆?jìng)爭(zhēng)市場(chǎng)下MR=AR所以MR=AVC是短期關(guān)停點(diǎn)嗎？那對(duì)于非完全競(jìng)爭(zhēng)下是MR=AVC呢還是TR=TVC是短期關(guān)停點(diǎn)？
24 The short-term breakeven point of production for a firm operating under perfect competition will most likely occur when:A price is equal to average total cost.B marginal revenue is equal to marginal cost.C marginal revenue is equal to average variable costs.1）這一題是怎么的出來的？已知短期盈虧平衡點(diǎn)是AR=ATC，因?yàn)槿魏问袌?chǎng)下P=AR，所以P=ATC嗎？2）另外我看到原版書上寫在完全競(jìng)爭(zhēng)和非完全競(jìng)爭(zhēng)下的盈虧平衡點(diǎn)都是AR=ATC，這個(gè)對(duì)嗎？原版書：A firm is said to break even if its TR is equal to its TC. It can also be said that a firmbreaks even if its price (AR) is exactly equal to its ATC, which is true under conditionsof perfect and imperfect competition.3）題目中如果說的average cost是默認(rèn)為average total cost嗎？
請(qǐng)老師分別講解一下三個(gè)選項(xiàng)對(duì)錯(cuò)的原因吧。這個(gè)題目不太理解，不知道對(duì)應(yīng)考點(diǎn)是啥
為什么Y增加Q就增加從而shiftright
MS_N變成MS_R為什么不是除inflation而是p?然后為什么Y不變？
貨幣需求量高，貨幣價(jià)格就會(huì)漲，這個(gè)好像說的是supplycurve,為什么不能是demandcurve呢
老師好，經(jīng)濟(jì)學(xué)的視頻課程，能再增加別的老師的授課的視頻嗎？?jī)蓚€(gè)老師的課都看一下，往往會(huì)起到互相補(bǔ)充的效果。
老師，怎么理解公司彈性和市場(chǎng)彈性？講義上好像沒提到這個(gè)吧
請(qǐng)問這道題是相當(dāng)于假設(shè)匯率標(biāo)價(jià)形式是DC/FC了嗎？但是題里沒說呀
請(qǐng)問這題老師用到的公式是在哪里講到的呀
這道題BC能講一下嗎
這道題問的是outcome，也就是本幣貶值會(huì)帶來什么結(jié)果，B和C看起來都是對(duì)的，是不是有點(diǎn)不嚴(yán)謹(jǐn)
