The paper is organized as follows: Section 2 discusses briefly two main groups of theories that link inflation and relative price variability and provides a sketch of a survey of the literature. Section 3 takes on Ball and Mankiw's models predicting the causality from relative price variability...

We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a stateregular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to...
