How can a country improve their balance of trade?
There are many ways a country can improve the Balance of Trade.The most simplistic of these is to export more goods than it imports. How a country does this, well there are numerous answers.The simple way is to depreciate its currency so it becomes relatively more expensive to import goods from other countries and simultaneously make exports seem comparably cheaper.There are countless other micro and macro-economic ways a country can do this, which could include banning certain imports (protectionism), imposing import quotas and tariffs, subsidising domestic exporters etc.
