Factors influencing menu costs

A 2015 study published by the MIT Press, used data from a national retailer operating a large number of stores selling groceries, health and beauty products to investigate the impact of that the number of product variants has on the frequency of price change. The study concluded that cost increases led to price increases on 71.2% of occasions for products with a single variant compared to 59.8% of the time where there were seven or more variants. This result was linked with the increased price stickiness associated with the additional cost of labour required to change the price of multiple items.
