Inter‐Firm Differences in Fed Cattle Prices in the Southern Plains
利用1989年6月南部平原肉类加工企业收购育肥牛的混合截面时间序列数据，发现不同企业间存在显著价格差异，三大企业整体支付价格低于小企业。
Abstract Pooled cross‐section time‐series data were used to assess inter‐firm differences in fed cattle prices paid by southern plains meatpackers during June 1989. Significant price differences were found among packers, even after accounting for numerous factors affecting fed cattle value. Some buyers paid higher prices and some lower prices than did one of the three largest packers. As a group, the Big Three firms paid lower prices than did smaller firms, both in the southern plains as a whole and in three of its subregions.
