This paper develops a model of competition among multiproduct retailers that is consistent with observed pricing regularities, such as the facts that virtually all products have large mass points in their price distributions and that most deviations fall below these mass points. The basis of the...

Recent theoretical research on retail pricing dynamics provides an explanation of why retailers periodically put items on sale, even when their costs are unchanged. The authors extend this research to show that more popular items (i.e., those that appeal to a wide range of consumers) are more...

We examine retail price variation across a range of goods and regions of the United States. We find that the typical grocery product has a regular price and stays at that price at least 50% of the time, and that most deviations from that regular price are downward. Temporary discounts or sales,...

Two common features of retailing are that each retailer sells many different products, and that pricing strategies differ across products. This paper extends previous work on single-product retailer competition to a multiproduct setting. Specifically, we derive equilibrium pricing strategies for...

We use a data set consisting of a three year panel of prices from a sample of gasoline stations located in suburban Washington DC and a corresponding census of the region's stations to develop three new empirical findings about retail gasoline pricing. First, while average retail margins vary...

Econometrics played a major role in the investigation and litigation of the Federal Trade Commission¡¯s (FTC) successful challenge to the proposed merger between two office superstore chains, Staples and Office Depot. Our goal in writing this essay is to describe the econometric issues at...

This study measures the effects of the Marathon/Ashland Petroleum (MAP) joint venture on rack and retail reformulated (RFG) gasoline prices in the four cities where both firms sold RFG before the joint venture. MAP was an early transaction in the recent era of petroleum mergers and resulted in...

This paper develops a bargaining model of wage and employment determination for the public sectror. The solution to the model generates structural wage and employment equations that are estimated using data from New York State teacher-school district collective bargaining agreements. An...
