Systems and methods for consumer price index determination using panel-based and point-of-sale market research data

A machine readable storage medium comprising machine readable instructions which, when executed, cause a machine to at least:

• obtain panelist market research data determined by monitoring items purchased by a plurality of statistically-selected panelists;
• obtain retail site market research data for items sold by a plurality of retail sites;
• determine weighted equivalent unit pricing information by combining the panelist market research data and the retail site market research data to determine the weighted equivalent unit pricing information for each group of common items in an item stratum of a consumer price index having substantially similar attributes except for an amount per unit;
• and
• determine the consumer price index using the weighted equivalent unit pricing information.

A system to determine a consumer price index, the system comprising:

• a first storage unit to store panelist market research data determined by automatically monitoring items purchased by a plurality of statistically-selected panelists;
• a second storage unit to store retail site market research data comprising point-of-sale data for items sold by a plurality of retail sites;
• an equivalent unit pricing processor to determine weighted equivalent unit pricing information by electronically combining the panelist market research data electronically retrieved from the first storage unit and the retail site market research data electronically retrieved from the second storage unit to determine the weighted equivalent unit pricing information for each group of common items in an item stratum of the consumer price index having substantially similar attributes except for an amount per unit;
• and
• a consumer price index processor to determine the consumer price index using the weighted equivalent unit pricing information.
