Slotting allowances: a time series analysis of aggregate effects over three decades

Slotting fees and related discounts are important but controversial mechanisms for obtaining shelf space in marketing channels for consumer packaged goods. The theoretical field is divided between the efficient market and the market power schools of thought. Results from empirical studies and analytical models point in different directions. This paper analyzes trends in key macro economic variables to see if the patterns are more consistent with an underlying market efficiency model vs. a market power one. The data span 30+ years and focus on retailers in the marketing channel for food and kindred products. The variables studied include new product introductions, retail selling area, consumer price indices, profitability, cost of goods sold and selling expenditures. Efficient market explanations do not fare well in the analyses in comparison with market power explanations for practically all the variables studied. The paper conlcudes with recommendations for regulators and retail management.
