The Skewness of the Price Change Distribution : A New Touchstone for Sticky Price Models
We present a new way of empirically evaluating various sticky price models used to assess the degree of monetary non-neutrality. While menu cost models uniformly predict that price change skewness and dispersion fall with inflation, in the Calvo model both rise. However, CPI price data from the late 1970's onwards shows that skewness does not fall with inflation, while dispersion does. We develop a random menu cost model that, with a menu cost distribution that has a strong Calvo feature, can match the empirical patterns found. The model therefore exhibits much more monetary non-neutrality ...

How Fast are Semiconductor Prices Falling?
The Producer Price Index (PPI) for the United States suggests that semiconductor prices have barely been falling in recent years, a dramatic contrast to the rapid declines reported from the mid-1980s to the early 2000s. This slowdown in the rate of decline is puzzling in light of evidence that the performance of microprocessor units (MPUs) has continued to improve at a rapid pace. Over the course of the 2000s, the MPU prices posted by Intel, the dominant producer of MPUs, became much stickier over the chips' life cycle. As a result of this change, we argue that the matched-model methodology ...
