Abstract

This paper examines whether sales promotions effectiveness depends upon the consumer’s brand loyalty and her buying behaviour and whether consumer’s behavioural characteristics in term of purchase frequency and level affect the response to promotional activities and moderate the effect of brand loyalty during the consumer choice process. Different specifications for the utility function, exploiting information on selling price, promotional activities such as displays usage, ad features in the store, 3x2 and discount, and differently brand loyalty measures have been estimated into a discrete choice framework, that is into the rational brand choice paradigm, paying attention to their effects on individuals’ probabilities to choose the specific brand during each purchase occasion. The application is run on a ACNielsen dataset of Italian households consumer panel, observed to buy at least two yoghurt packages during a year, matched to store panel data with respect to quantities, prices and promotions.
