A Competitive Pricing Model

This paper is principally concerned with the development of a competitive pricing model aimed at predicting the impact of a vector of price increases on sales of a given brand of a low priced, frequently purchased product. The model has its base in a set of assumptions describing the purchasing behavior of the individual consumer. A method for testing the model against empirical data is described and illustrated. The competitive pricing model is found to perform somewhat better than a simple regression model in the application reported.
