Abstract: | This paper proposes a dynamic state-space Almost Ideal Demand System (AIDS) model of brand share. The model is applied to a small segment of the toiletries category comprising four differentiated brands and covering over five years of quad-weekly time series data. The results show a significant improvement over the conventional AIDS model, indicating short-run competition on the basis of price and promotional activity. Long-run analysis, however, suggests that such activity exerts no sustainable impact on the share of competing brands. |
