The effect of odd pricing on demand

Abstract

Presents the findings of a study designed to investigate the effect of odd pricing on respondents’ purchase probabilities for six products ranging in price from $5 to $100. The products tested were a block of cheese, a frozen chicken, a box of chocolates, a hair dryer, an electric kettle and a food blender, and the data were collected in a mall intercept of 300 household shoppers. For each product a demand curve was estimated and the differences between expected and actual purchase probabilities at each odd price level examined. For all six products, demand was higher than expected at one or both of the odd price points tested. This effect was particularly marked for the lower‐priced food items (cheese, chicken and chocolates) and for prices ending in the digit 9. Provides support for the assumption that odd pricing generates greater than expected demand and for the common practice of setting retail prices which end in 99 cents or $99.
