On the Prediction Power of Market Share Attraction Models
研究了市场份额吸引力模型在理论上优于常用模型后，是否在实际预测中表现更好，实证结果初步支持这一观点。
Logical consistency of market share models has received considerable attention in the recent marketing literature. The reports suggest that, at least theoretically, attraction-type specifications are more easily justified than the ones commonly used in empirical work. The authors examine whether the theoretical superiority also implies a better predictive performance. The empirical results give a tentatively affirmative answer.
