The study looked at what factors affect how much money people in Gulf Cooperation Council countries want to hold. They used data from 1980 to 2014 and found that income and exchange rates make people want more money, while inflation and interest rates make them want less. In the short term, only income affects money demand. The researchers also found that the model they used is stable, suggesting that controlling the amount of money in circulation could be a useful tool for policymakers.
