This paper elaborates on the alternative measure of persistence recently suggested in Marques (2004), which is based on the idea of mean reversion. A formal distinction between γ, the unconditional probability of a given process not crossing its mean in period t and γ̂, its estimator, is made...

This paper elaborates on the alternative measure of persistence recently suggested in Marques (2004), which is based on the idea of mean reversion. A formal distinction between the "unconditional probability of a given process not crossing its mean in period t" and its estimator, is made clear...

This paper brings together empirical research on price and wage dynamics for the Portuguese economy based both on micro and macro data. As regards firms' pricing behaviour the most noticeable finding is that prices in Portugal are somewhat less flexible than in the United States but more...

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...

Infrequent price changes at the firm level are now well documented in the literature. However, a number of issues remain partly unaddressed. This paper contributes to the literature on price stickiness by investigating the lags of price adjustments to different types of shocks. We find that...
