PRICE VARIABILITY OR RIGIDITY IN THE FOOD-RETAILING SECTOR? THEORETICAL ANALYSIS AND EVIDENCE FROM GERMAN SCANNER DATA AgEcon
Herrmann, Roland; Moser, Anke.
In many industrialized countries, the grocery-retailing sector exhibits a strong and increasing market concentration. Hence, it is important to understand retail pricing for many questions related to market power in the marketing chain and to agricultural and food policies. We analyze intertemporal pricing of grocery retailers in Germany with a large set of scanner data for processed foods. In theory, food prices could be rather variable, e.g. due to fluctuating commodity prices in a competitive world, or rather rigid, e.g. due to price adjustment costs. We elaborate that retail sales are crucial and raise food price variability at the points of sale. Despite this, prices are rather rigid and often do not change for many weeks.

IMPACT OF FOOD CONTAMINATION ON BRANDS: A DEMAND SYSTEMS ESTIMATION OF PEANUT BUTTER AgEcon
Bakhtavoryan, Rafael; Capps, Oral, Jr.; Salin, Victoria.
A 2007 foodborne illness incident involving peanut butter is linked with structural change in consumer demand. Compensated and uncompensated own- and cross-price elasticities and expenditure elasticities were calculated for leading brands before and after the product recall using the Barten synthetic model and weekly time-series data from 2006 through 2008. Statistically significant differences in price elasticities for the affected brand, Peter Pan, were absent. After a period of 27 weeks, this brand essentially recovered from the food safety crisis. Significant differences in price elasticities were evident among non-affected brands. Hence, spillover effects and heightened competition are associated with the recall.
