Price-Quality Correlations for Packaged Food Products

ABSTRACT

Prior investigations have indicated that relationships between price and product quality are considerably weaker for non-durables than for durables. Among non-durables, packaged food products frequently have exhibited the poorest correspondence between price and quality. This study, utilizing data from Consumers Union, analyzes the relationships between price and a measure of product quality for 679 brands in forty packaged food product classes over a fifteen year period. The study generally confirms earlier preliminary conclusions that the correlation between quality and price for packaged food products is near zero. In addition, the findings indicate that convenience foods, particularly frozen foods, display the poorest correspondence between price and product quality with more than 43 percent of all frozen food product classes exhibiting negative relationships between price and product quality. Some possible explanations for these findings and their implications for public policy are advanced.
