The study looked at whether the idea of saving more money leading to economic problems applies to Nigeria. They used data from 1986 to 2019 to see how national income, saving, investment, and spending are connected. The results showed that when national income goes up, people tend to save more and spend more. This means that the paradox of thrift is true for Nigeria. The focus of economic policies should be on increasing national income, not just saving money, because when national income goes up, both saving and spending increase in Nigeria.
