The researchers looked at how government money impacts Tunisia's economy. They used data from 2000 to 2019 and found a few things. When the government spends more, it doesn't always boost the economy by a lot. Spending more on things like goods and services doesn't have a big effect and might even push out private spending. However, investing more can have a better impact. After the 2011 revolution, the government spending didn't help as much, especially during tough times. If Tunisia faces problems with its own production, it might change how government spending affects the economy, making it less effective.
