A comprehensive model of buying behavior
Book •
The Dirichlet model, developed by Goodhardt, Ehrenberg, and Chatfield, revolutionized the understanding of consumer buying behavior.
It challenges traditional notions of brand loyalty, demonstrating that purchasing patterns are remarkably predictable across various product categories.
The model highlights the importance of market reach over deep customer loyalty, suggesting that acquiring new customers is more impactful than fostering intense loyalty among existing ones.
This research emphasizes the prevalence of light buyers and the consistent distribution of buyers across brands, regardless of size.
The model's implications have significantly influenced marketing strategies, shifting focus from loyalty programs to broader market penetration.
