An increasing literature has been concerned that the dynamics of the economy keeps switching and that, in particular, it is important to allow time variation in the degree of Calvo stickiness. We investigate this with a Markov-switching Dynamic Stochastic General Equilibrium model and show that there is little gain when allowing for such time variation. As a result we recommend to use a constant Calvo stickiness parameter, even when allowing for regime shifts elsewhere.
