Technological Change and Economies of Scale in U.S. Poultry Processing
利用人口普查局独特数据集和超越对数成本函数，实证分析美国禽类加工业的技术变革，发现显著的规模经济且不随工厂规模递减，远大于牛猪屠宰业，暗示整合可能持续。
Abstract This article uses a unique data set provided by the Census Bureau and a translog cost function to empirically examine technological change in the U.S. poultry industry. Results reveal substantial scale economies that show no evidence of diminishing with plant size and that are much greater than those realized in cattle and hog slaughter. Findings suggest that consolidation is likely to continue, particularly if demand growth diminishes, and that controlling for plant product mix is critical to accurate cost estimates.
