摘要

由于横截面数据的限制，过去为牛市属性定价的尝试依赖于静态边际估值。本分析利用印第安纳州17年的牛市拍卖数据，调查牛市买家对安格斯牛属性的边际估值是否随着时间的推移而变化。结果表明，时间对某些性状(如肋眼面积、肌间脂肪百分比、肋眼面积预期子代差异[EPD]和母乳EPD)的影响具有统计学意义。并非所有这些影响都与先前的预期相符。尽管如此，研究结果对牛肉行业在信号质量问题和以epd形式整合已证实的信息方面具有重要意义。

Temporal Changes in Angus Bull Attribute Valuations in the Midwest

Past attempts to price bull attributes have relied on static marginal valuations due to crosssectional data limitations. This analysis investigates if bull buyers’ marginal valuations of Angus bull attributes have changed over time using 17 years of bull auction data from Indiana. Results indicate statistically significant time effects on some traits (e.g., ribeye area, percent intermuscular fat, ribeye area expected progeny difference [EPD], and maternal milk EPD). Not all of these effects align with prior expectations. Nonetheless, results have important implications for the beef industry in terms of signaling quality ques and incorporating proven information in the form of EPDs.
