Doctorate project reveals discrepancies in retail pricing

Identical products are sold at different prices. “Half of these differences can be explained by which shop you’re buying from,” says Øyvind Nilsen Aas, PhD in Economics.

In his doctorate project at BI Norwegian Business School, Øyvind Nilsen Aas examined price differences in the Norwegian retail grocery trade.

The study showed that the retail industry operates with different prices for completely identical products, such as 1.5-litre bottles of Coca-Cola or Milo wool detergent. The price variations are relatively modest for some products, while for others, like Coca-Cola, the price differences may be substantial.
