The study looked at how devaluing Nigeria's currency affects its trade balance from 1970-2010. They found that devaluation of the exchange rate actually makes Nigeria's trade balance worse in the long run. There is a strong connection between trade balance and factors like domestic income, money supply, interest rates, and exchange rates. Money supply changes have a bigger impact on trade balance than exchange rate changes. Overall, the research suggests that increasing the money supply has a bigger effect on improving trade balance than devaluing the currency.
