To optimize the promotion plan for a consumer good, measurements of the specific impact of the promotion component are needed. The use of Scanner data allows for a precise measurement of the impact of promotion at the store or at the consumer level. This paper outlines the value of quasi-experimental data as well as the need and the application of an explicative model based on regression to carry out an analysis of the effect of promotion. The specifications of the model allow for an anaysis at the store level and as well, allow us to study separately, the effects of price promotion and price reduction.
