The ERIM data include information collected by the now-defunct ERIM division of A.C. Nielsen on panels of households in two mid-sized Midwestern cities. Information is available on the purchases of households in a number of product categories along with household demographic information.
For a subset of households, TV viewing data is available to measure exposure to commercials involving the products in each of the ERIM categories.
These data are for academic research purposes only. Users must acknowledge in their working papers and/or publications the Kilts Center for Marketing at the University of Chicago Booth School of Business.
These files are in a directory tree that starts from acnpanel. The files are accessible via anonymous ftp. There are two branches in the tree:
- Raw Files: This contains the original F1 - F11 from the ERIM tapes for each of the ERIM and single-source categories.
- SAS Files: This contains SAS export format files for the main household demographics, household purchase records, and shopping occasion files of both the ERIM and single-source categories. There are also retail price files. See those directories for detailed documentation. These files are unsupported by the Kilts Center.
The original ERIM documentation (PDF) is needed only if you want to use the raw files.
