The study looked at how government spending in Nigeria affects the country's economic growth from 1991 to 2021. They used a statistical method called Autoregressive Distributed Lag to analyze the data. The results showed that while government spending on things like roads and buildings helped the economy grow, spending on other areas didn't have the same positive impact. The study suggests that the government should focus on improving how they spend money on projects to boost economic growth, and also be careful about borrowing too much money to avoid getting into debt.
