Database Paper—The IRI Marketing Data Set

This paper describes a new data set available to academic researchers (at the following website: http://mktsci.pubs.informs.org ). These data are comprised of store sales and consumer panel data for 30 product categories. The store sales data contain 5 years of product sales, pricing, and promotion data for all items sold in 47 U.S. markets. In two U.S. markets, the store level data are supplemented with panel-level purchase data and cover the entire population of stores. Further information is available regarding store characteristics in these markets. We address several potential applications of these data, as well as the access protocol. The data set described in this paper is maintained by IRI. Any fees charged by IRI for the distribution of the data set will be used for the continual maintenance and updating of the data. Scholarships to cover IRI's fees (for those who need it) are available through the INFORMS Society for Marketing Science (ISMS). Please see the website above for further details.
