Rule-of-Thumb Consumers, Nominal Rigidities and the Design of Interest Rate Rules

AUTHOR(s): Ocampo Diaz, Sergio
RELATED TOPICS: Macroeconomics


This paper argues that, in the presence of nominal wage rigidities, the exis- tence of Rule-of-Thumb agents and price rigidities does not cause a change in the Taylor Principle as suggested by Galí et al. (2004), and that the only rigid- ity relevant for this result is that faced by Rule-of-Thumb consumers. For doing so, a New-Keynesian model with Rule-of-Thumb agents is proposed. The model discriminates betwen both type of agents when defining wage rigidities, thus al- lowing to identify and measure the factors that affect the Taylor Principle, this also allows to drop complete markets for Rule-of-Thumb agents, and the simple use of non-separable utility functions in order to determine the incidence of the wealth effect when facing staggered wages.
