The net trade balance is the difference between the value of exports and imports (X-M)
-

Examiner Tips and Tricks
When evaluating the extent to which the trade balance strengthens or weakens as a result of exchange rate changes, remember that it is dependent on the price elasticity of demand (PED) of the exports and imports.
This is explained by the Marshall Lerner Condition and the J Curve.
The Marshall-Lerner Condition states that the depreciation/devaluation of a country’s currency will lead to an improvement in its net trade balance only if the sum of the price elasticities of its exports and imports is greater than one
The J Curve argues that a net trade balance will worsen in the short term after a currency devaluation but then improve in the medium to longer term.
