Now exporters need to improve their efficiency to stay alive.
Inefficient exporters do not want to improve their efficiency. Currency depreciation is easy money for them.
What is the bottom line ?!
The country should not rely just on exporting simple products like textiles, and minerals from your country. Software is a good example of quality export. It can with stand further rupee appreciation. Because importers do not have cheaper, quality alternatives.
Unemployment in the country should dictate what the exchange rate should be.
Currently unemployment rate in Indian big cities (like Chennai) is like 1.5% This is unheard thing in Indian history.
When there are lot of unemployed people, as a country you won't mind them working for foreigners. (not directly, but in producing simple things/services for exports.)
But with current low unemployment rate rupee appreciation is in nation's interest.
