This paper argues that the cross-sectional approach to durations is essential to understand nominal rigidity because this captures the fact that price-spells are generated by firms' price-setting behavior. Since the distribution of durations is dominated by a proliferation of short contracts, the cross-sectional measure corrects for this by length-biased sampling. Modelling the price-spell durations in this way enables us to see how Taylor, Calvo and their generalizations relate to each other, and enable us to compare price-setting behavior for a given distribution of durations. We also show how the micro-data can be directly related to the macroeconomic pricing models in this setting.
