Solution to 1最后一段，Because the Marshall–Lerner condition is not satisfied, exchange rate movements do not move the trade balance in the expected direction [i.e., appreciation (depreciation) of the currency does not decrease (increase) the trade balance]. 請(qǐng)問這句話涉及的知識(shí)點(diǎn)，在教材第幾頁有明確寫？并且接下去的這句話However, note that with different import/export weights and the same elasticities, the Marshall–Lerner condition would be met. 這句話涉及的知識(shí)點(diǎn)，在教材第幾頁？3. Solution to 1最后一段的最后一句話，4和7，這兩個(gè)數(shù)字哪兒得出的？為什么the condition would be met, ωX 必須大于 4/7？

1只有在進(jìn)口商品或出口商品中至少有一方的需求彈性是富有彈性（即需求彈性的絕對(duì)值大于1)時(shí)，才能實(shí)現(xiàn)通過貨幣的貶值改善貿(mào)易逆差 。 這一前提假設(shè)稱為marshall lerner condition
2 453頁If this condition is satisfied, a devaluation/depreciation of the domestic currency will move the trade balance toward surplus.
3 是根據(jù)公式化簡(jiǎn)出來的一種特殊情況
4 4/7 *0.3+3/7*（-0.4）剛好等于0
