ABSTRACT: Thanks to recent findings based on survey data, it is now well known that firms differ from each other with respect to their price-reviewing strategies. While some firms review their prices at fixed intervals of time, others prefer to perform price revisions in response to changes in economic conditions. In order to explain this fact, some theories have been suggested in the literature. However, empirical evidence on the relative importance of the factors determining firms' different strategies is virtually nonexistent. This paper contributes to filling this gap by investigating the factors that explain why firms follow time-, state- or time- and state-dependent price-reviewing rules. We find that firms' strategies vary with firm characteristics that have a bearing on the importance of information costs, the variability of the optimal price and the sensitivity of profits to non-optimal prices. Menu costs, however, do not! seem to play a significant role.
