Equilibrium Determinacy of Endogenous Growth with Generalized Taylor Rule: A Discrete-Time Analysis

This paper examines equilibrium determinacy of a discrete-time AK growth model with a generalized Taylor rule under which interest rate responds to the growth rate of real income as well as to the rate of inflation. We use the standard money-in-the-utility formulation in which money is superneutral on the balanced-growth path. We show that even in such a simple environment, the generalized Taylor rule may yield indeterminacy of equilibrium easily. We also demonstrate that equilibrium determinacy depends on the timing of money holding of households as well.
