The study looked at how government spending and private consumption affect the economy. They used data from five countries and statistical analysis to see if government spending complements or replaces private consumption. The results showed that government spending actually complements private consumption, meaning they work together to boost the economy. Even when other factors are considered, the positive relationship between government spending and private consumption remains. This suggests that when the government invests in things like healthcare and education, it can lead to increased private spending and economic growth.
