Abstract:
A fresh interpretaion is provided of the influential finding that the markup of prices over marginal costs is counter-cyclical. Using Rotemberg and Woodford's data set we argue that the markup is best modelled as a variable that is integrated of order one. A consequence of this finding is that the markup cannot be related in the long run with business-cycle variables since these are traditionally thought of as being stationary.
