根據(jù)供給曲線(xiàn),當(dāng) P越小的時(shí)候,產(chǎn)量也會(huì)更小吧?怎么會(huì)更多呢?
這里的供給曲線(xiàn)和生產(chǎn)曲線(xiàn)是市場(chǎng)的?還是生產(chǎn)商的? 社會(huì)總福利的最優(yōu)點(diǎn)是哪一點(diǎn)? 為什么看到說(shuō)社會(huì)總福利的最優(yōu)點(diǎn)是完全競(jìng)爭(zhēng)市場(chǎng)下需求和供給均衡的點(diǎn)?
老師你好，這里three-month forward points = 12.8，是不是就是說(shuō)3個(gè)月后usd/eur=1.164+0.00128，那是不是說(shuō)1美元能換到更多的歐元？
這樣計(jì)算面積不對(duì)把, 我覺(jué)得只有橫坐標(biāo)是邊際產(chǎn)量的時(shí)候才能這樣計(jì)算面積, 就好像概率密度函數(shù)的積分才是概率, 而概率函數(shù)不能用面積表示概率.
您好，這個(gè)圖里面，老師說(shuō)consumer suplus時(shí)，說(shuō)這個(gè)商品的成本是2萬(wàn)，而消費(fèi)者愿意出10萬(wàn)，9 萬(wàn)或者8萬(wàn)，都比商品成本高，對(duì)消費(fèi)者好，是consumer suplus，但這里應(yīng)該是消費(fèi)者賠錢(qián)了，因?yàn)橘I(mǎi)貴了，這不應(yīng)該是對(duì)生產(chǎn)者好嗎？所以上半個(gè)三角不應(yīng)該是producer suplus?
Module 2-書(shū)（2022-L1V1）P105-最后一段中所說(shuō)的，If the café could extract from you the maximum amount each month that you would be willing to pay for the half-price option, then it would successfully have removed the income effect from you in the form of a monthly fixed fee. 這句話(huà)怎么理解，為什么會(huì)remove the income effect? 而且是以monthly fixed fee的形式？
為什么陰影部分可以解釋為消費(fèi)者盈余，可以詳細(xì)解釋下嘛？
Module 2-Economics-書(shū)（2022-L1V1）P92-當(dāng)中部分，450 – 2q1 – q2，這個(gè)是怎么求出的？為什么MR1 = ΔTR1/Δq1 = 450 – 2q1 – q2, and MR2 = ΔTR2/Δq2 = 450 – q1 – 2q2.導(dǎo)數(shù)是怎么計(jì)算的？
If the domestic country desires to reduce a current account surplus, the most likely outcome is that it will： A lend to foreign countries. B encourage foreign direct investment. C have a lower gross domestic product (GDP) than if it were a closed economy.這兩道題有啥區(qū)別呢，感覺(jué)答案講的相反
Module 1-官網(wǎng)習(xí)題-Question 52-（1）Normal goods的定義是？書(shū)上第幾頁(yè)上有？（2）Normal goods與inferior goods, veblen goods的區(qū)別是？

為什么st模式下是fd標(biāo)價(jià)法
緊縮的貨幣政策和寬松的財(cái)政政策使output higher；寬松的貨幣政策和緊縮的財(cái)政政策卻使output varies。為什么？
Module 1-Economics-書(shū) (2022-L1V1) P44-Exhibit 23下方第一段中，Accordingly, if the firm were planning to produce output greater than Qb, it would choose Plant Size 3 because its cost for any of those levels of output would be lower than for Plant Size 1 or 2. 根據(jù)Exhibit 23所示，由Qb對(duì)應(yīng)的左側(cè)左側(cè)點(diǎn)$/Time Period, 它的成本不是大于Plant size 1和2嗎？為什么說(shuō)Plant size 3的成本小于plant size 1和2？
Module 1-Economics-1. 書(shū)（2022-L1V1）P31-請(qǐng)問(wèn)怎么理解截圖中標(biāo)黃部分的句子：If one additional hour of labor input causes MC to fall, the firm would want to add that hour and continue adding labor until SMC becomes positively sloped. 為什么會(huì)是positively sloped的？
