The study looked at changes in money demand in Turkey from 1986 to 2020. Overall, the demand for money was found to be unstable. However, using a special analysis, it was discovered that the money demand model can be split into two different stable periods. This means there is a transition period where stability is lost in money demand. The analysis showed that the relationship between money demand and factors like price level, income, interest rate, and people's money preferences remains consistent over time.
