A Regression
Tree Approach for Optimizing Price and Package Offerings
Bruce Ratner, Ph.D.
Selecting the correct
price for a product is a crucial decision often faced by marketers.
Further complicating matters are packaging issues, as price is directly
related to the product attributes and the positioning of the product
offering in relation to the competitors' products. The traditional
method of solving the pricing and packing issues is the parametric,
assumption-full conjoint analysis. The purpose of this article is to
present a regression tree alternative, such as CHAID,
to the conjoint paradigm that eliminates some of the thorny
practical matters of implementing the high-wrought conjoint analysis:
incorporating nonlinearities and nonadditivities in the final conjoint
model solution. Two cases studies are discussed comparing and
contrasting the traditional conjoint method and the nonparametric,
assumption-free (and model-free!) regression tree approach for
determining the optimal price and packaging based upon dozens of
product attribute combinations.
