Abstract
This paper develops an algorithm, called the sales spotter, which identifies the sale prices in the transaction price series provided in point-of-sale data. The goal of the sales spotter is to identify the maximum number of sale prices while minimizing the incorrect attribution of non-sale price reductions to sale prices. The spotter is developed and the values of its parameters are selected by analysing around 7.5 million agged sales in a US supermarket scanner data. At the optimal values of the parameters, the spotter identifies 84% of authentic agged sale weeks in the data.
