"We explore the role of strategic price-discrimination by retailers for price determination and inflation dynamics. We model two types of customers, "loyals" who buy only one brand and do not strategically time purchases, and "shoppers" who seek out low-priced products both across brands and across time. Shoppers always pay the lowest price available, the "best price". Retailers in this setting optimally choose long periods of constant regular prices punctuated by frequent temporary sales. Supermarket scanner data confirm the model's predictions: the average price paid is closely approximated by a weighted average of the fixed weight average list price and the "best price". In contrast to standard menu cost models, our model implies that sales are an essential part of the price plan and the number and frequency of sales may be an important mechanism for adjustment to shocks. We conclude that our "best price" construct provides a tractable input for constructing price series"--National Bureau of Economic Research web site

Abstract
A substantial empirical literature documents value-destroying "cross-subsidization" among the divisions of diversified firms. However, this literature relies upon two maintained hypotheses: that divisions of diversified firms are randomly allocated to their corporate parents and that the investment opportunities facing conglomerate divisions are identical to those of stand-alone firms in their industries. I examine the investment behavior prior to merger of a sample of firms that undertook diversifying mergers between 1980 and 1995. I show that, in my sample, investment patterns that the literature has attributed to cross-subsidization between divisions are apparent in the pairs of merging firms prior to their mergers. Thus, some of the cross-subsidization results in the literature may be attributable to selection bias. I also examine stock market responses to announcements of diversifying acquisitions. The event responses are largely independent of measures of the extent to which the merger is diversifying.
