Patterns in Parameters of Buyer Behavior Models: Generalizing from Sparse Replication

Elasticities calculated from estimates of parameters in four consumer behavior system models are pooled in order to assess systematic differences related to variables and to study characteristics. The pooling proves to be plausible because the elasticities from particular variable pairings do not vary systematically with study characteristics. Few elasticities other than those associated with controllable exogenous variables (price and distribution) differ significantly from the overall mean, although the mean elasticity is significantly different from zero. The magnitudes of estimated elasticities indicate that the system would tend to converge after being subjected to external shock.
