The uniqueness of steady-state equilibrium under state-dependent pricing: The case of deflation

Author

  • Takahashi, Shuhei

Abstract

John and Wolman (2004, 2008) show that steady-state equilibrium is likely to be unique under inflation (i.e., a positive net inflation rate) in a New Keynesian state-dependent pricing model based on the Dotsey et al. (1999) model. I show that the uniqueness of equilibrium holds in a stronger way under deflation (i.e., a negative net inflation rate).
