Animal Identification and Tracing in the United States
研究美国动物标识与追溯系统对肉类和畜牧业的成本影响，发现国内牛肉需求小幅增长或恢复日本市场份额即可抵消系统成本。
We examine the impacts of adopting animal identification and tracing systems on the U.S. meat and livestock industry. Using a multimarket equilibrium displacement model, we find that a modest increase in domestic demand for beef would offset the costs of an animal identification system. Similarly, an increase in beef export demand equivalent to Japan's beef export market share prior to the 2003 U.S. discovery of bovine spongiform encephalopathy would offset animal identification system costs.
