Assume the following to be true:
Export contracts are denominated in domestic currency. Import contracts are denominated in foreign currency. The foreign supply of exports or 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, and be sure to explain why these effects occur.
The impact of exchange rate fluctuation can be evaluated in three different stages.

This solution explains what will happen to the domestic trade balance following a devaluation of the domestic currency.
