The study looked at why Nigeria's inflation rate is high. It used Nigerian data from 1970 to 2017 to see if increasing money supply causes inflation, as some believe. The results show that while more money can cause short-term inflation, other factors like GDP also play a role in the long run. This challenges the idea that inflation is only caused by too much money in the economy. The research suggests that different theories should be tested to better understand and solve high inflation rates in countries like Nigeria.
