The study looked at how different fiscal rules affect the economy of Kazakhstan during changes in oil prices. They used a model to simulate the impact of fiscal policies on the economy. The results showed that when the government adjusts spending in response to oil price changes, a drop in oil prices leads to a decrease in output. However, if the government follows a different fiscal rule, output actually increases when oil prices drop. This shows that having a countercyclical fiscal policy can help stabilize the economy during times of economic shocks, especially when combined with active inflation control by the central bank.
