Question

'Devaluation and Depreciation of currency are one and the same thing'. Do you agree? How do they affect the exports of a country?

Answer 1

Devaluation is the fall in the value of domestic currency in relation to foreign currency as planned by the government in a situation when exchange rate is not determined by the forces of demand and supply, but is fixed by the government of different countries.
Whereas, Depreciation is the fall in the value of domestic currency in relation to foreign currency in a situation when exchange rate is determined by the forces of demand and supply in the international currency market.
As a general phenomena, any depreciation/devaluation of currency may result into increase in exports of the goods and services from the country since it would increase the global competitiveness of the goods by making them cheaper.
