What is Marshall Lerner Condition?

Marshall Lerner Condition states that, devaluation will improve the balance of payments of a country. If the sum of elasticities of demand for a country’s exports and of its demand for a countries imports is greater than one (1).

It can be expressed as follows –

ex + em > 1

If ex + em < 1, then the devaluation will disturbs the balance of payment position.

If ex + e= 1 then the devaluation will not have any direct effect on the BOPs of a country.

The Marshall-learner condition can specify the situations in which devaluation can successfully improve the balance of trade and the balance of payments. These conditions are mentioned below –

If the sum of elasticities of demand for exports and imports is greater than unity, devaluation improve the balance of payments (i.e., reduce deficit).

If the sum of these elasticity co-efficient is equal to unity, devaluation will leave the balance of trade and payments unchanged.

If the sum of these elasticity co-efficient is less than unity, devaluation can cause the worsening of the balance of payments (i.e., increase deficit).
