Inflation is a big problem in many countries, affecting people, businesses, and governments. This study looked at the relationship between money and prices in Algeria, Morocco, and Tunisia. The results suggest that in Morocco and Tunisia, more money in the economy leads to higher prices. This means that controlling the amount of money circulating can help control inflation. However, in Algeria, there doesn't seem to be a clear link between money and prices, possibly due to unreliable data on prices. Overall, the findings support the idea that managing the money supply can help manage inflation in these countries.
