When Do Large Buyers Pay Less? Experimental Evidence
通过实验室实验检验理论预测：大型买家能否获得价格折扣取决于其相对规模与卖家竞争程度，买家规模分布和卖家数量的细微变化会显著影响折扣是否存在。
The rise of mega‐retailers has precipitated a growing literature on large‐buyer discounts. According to R otemberg and S aloner [1986] and S nyder [1998], large buyers' ability to obtain price discounts depends on their relative size and the degree of seller competition. I test experimentally implications of this theory concerning the number of sellers and the sizes of buyers in the market. The results track the comparative‐statics predictions to a surprising extent. Subtle changes in the buyer‐size distribution or number of sellers can create or negate large‐buyer discounts. The results highlight the previously unexplored role of the demand structure in determining buyer‐size discounts.
