Abstract:

Three detailed examples are given here for each of the subareas of product and price policy, distribution policy and advertising policy. In each case a tentative theory is postulated and evaluated in the light of the data available. Firstly, a split-run-test for measuring the brand-substitution effect of price changes is discussed. The second model refers to the estimation of the turnover of individual outlets. The final example introduces a learning type of advertising response function, which seems to be useful for auditing advertising performance on a continuous basis.
