Financial innovations and the interest elasticity of money demand: Evidence from an error correction model

The difficulty of estimating a stable money demand function has been blamed on financial innovations of the past two decades. Gurley and Shaw's [1960] thesis implies that a proliferation of money-like assets resulting from financial innovations increased the interest elasticity of money demand. However, Hafer and Hein [1984] provided empirical evidence to the contrary. This paper presents the empirical results of the M2 demand for money using an error correction model for the period 1959:1-87:4 and two subperiods 1959:1-73:4 and 1974:1-87:4. The findings suggest lower interest and price elasticities for money demand in the second sample in which money substitutes proliferated.
