Concept:Devaluation makes a country's exports cheaper for foreign buyers, increasing demand and potential export earnings.
Explanation:When a country devalues its currency, its goods become less expensive in foreign currency terms.
This lower price makes exports more attractive to international buyers, leading to a rise in the volume of goods sold abroad.
The increase in export volume can raise total foreign exchange earnings despite the lower unit price.
In contrast, increasing export duty raises prices and reduces competitiveness.
Increasing import duty does not directly boost exports.
Currency appreciation makes exports more expensive, reducing foreign demand.
Therefore, the best way to earn more from exports is to devalue the currency.
