Between 1967 and 1979, we produced a number of studies that explored different facets of the economics of advertising. This work culminated in our 1974 book entitled Advertising and Market Power. Our leading hypothesis was that heavy advertising expenditures often but not always had...

We combine two data sets to study price rigidity. The first consists of weekly time series of retail, wholesale, and spot prices for twelve products. These time series contain two exogenous cost shocks. We find that prices exhibit more rigidity in response to the second shock than the first. The...

This paper analyzes the impact of vertical integration on product quality. Contrary to previous findings, it is shown that integration decreases quality in many natural situations. In general, the direction of the quality change is governed by three effects that are isolated in the model. This...
