Territory Sales Response Models: Stability over Time

Empirical tests of territory sales response models have involved primarily a cross-sectional analysis of a salesforce at one point in time. Because such models often influence subsequent management decisions, the assumption that such models are stable over time is an important one. The authors consider factors that could influence the stability of such a model and use a five-year data base to explore the stability of a previously reported model of territory sales response. In this data base all the parameters appear to be stable over time.
