Government spending in South Africa from 1990 to 2015 was studied to see how it affects economic growth. The researchers used a special model to analyze the data and found that more government spending actually leads to less economic growth in the long run. They also discovered that economic growth causes government spending to increase, not the other way around. This means that in South Africa, government spending is a result of economic growth, not a cause of it. These findings match what other studies have found in the past.
