Open AccessThis study aims to examine, especially the effects of interest rate (time deposit and treasury bills) volatilities on the demand for money in case of Turkey for 1987: 1-2007: 3 period. Quarterly data of all variables are used as the research data and Pesaran, Shin and Smith (2001) 's bound test is used as the research method. In computing interest rate volatilities, moving-sample standart deviation method which is proposed by Kenen and Rodrik (1986) and Koray and Lastrapes (1989) is used. According to the results, the long run coefficient of gross domestic product is positive and statistically significant as expected. Although, the volatility of interest rate on treasury bills is positive as expected, it is statistically insignificant. On the other side, the coefficient of volatility of interest rate on time deposit, the coefficient of inflation rate and the coefficient of exchange rate are all negative and statistically significant as expected.
