Brand switching models

The present paper describes the devices adopted in order to construct the transition matrix which is going to serve as the model's input : they involve breaking down each purchasing sequence into pairs of elementary purchases. But this in turn...

Comment on A.S.C. Ehrenberg's paper

On the first place, it has to be said that the group members consider it as a jolly good idea to observe the purchasing habits over quite long periods of time instead of making conclusions based on elementary purchasing behaviour. But they regret...

Contribution of discussion to the papers of Mr. Ehrenberg and Mr. Hamre

The present stage you can characterise as initial stage of research work. In our opinion it will be necessary to use stochastic processes in the analysis of brand-switching.

Comment on session II

In Group 1 the discussion of brand switching was centred first on whether or not Markov chains were a useful concept in this area.

Comment on H. Hamre's paper

The usefulness of the Markov chains was of course discussed with the two speakers; they had actually adopted very different positions on that point.

An empirical approach to brand-switching

The number of people who buy two particular brands in a given time period does not depend on the brands as such but only on the numbers of people who buy each brand and on a general constant. The constant varies by product-field and by the length of...

The application of stochastic processes by studying switches and stability

The aim of this work is ''building out" the simple Markovian model in a more realistic direction assuming that the time between sequencial purchases is variable. To study the complete relationship between "the marketing input variables" and brand...

An empirical approach to brand-switching (Discussion)

One question which has been raised in the discussion is that of assessing a manufacturer's scope for launching an additional brand in a product-field instead of simply pushing his existing brand. This is in fact one of several kinds of practical...
