We show that a simple model of individual learning can explain these different aggregate outcomes within the same experimental setting. The key idea is evolutionary selection amo...

We combine two unique data sets to document and explain a time varying price rigidity. The first data set consists of the time series of actual retail and wholesale transaction prices, and a measure of upstream commodity cost for 12 products in refrigerated and frozen orange juice categories collected weekly over a three-year period, 1989–1992, at a large midwestern supermarket chain. A special...
