帮忙做下题谢谢

. Assume the following to be true.




Export contracts are denominated in domestic currency.


Import contracts are denominated in foreign currency.

The domestic supply of exports is inelastic.

The foreign supply of exports (domestic imports ) is inelastic.

What will happen to the domestic trade balance following a devaluation of the domestic currency? Explain carefully the effects during the currency-contract period and the pass-through period, including why these effects occur.

这个问题应该分短期和长期来分析。
短期，由于国内货币贬值，进口合同以外币计价，相对的国外商品变得更贵了，需要支付更多的本币，贸易条件恶化，减少贸易顺差或增加贸易逆差。
长期，由于本币贬值，国内商品相对国外变得更便宜了，促进出口，改善贸易条件，增加贸易顺差或减少贸易逆差。
这就是教科书上说的，货币贬值产生的J曲线效应。短期使贸易恶化，长期使贸易改善。
不知道这么解释你清楚了没。如果清楚了麻烦给几个论坛币吧，嘿嘿。
