The value of genetic information to livestock buyers: a combined revealed, stated preference approach
结合实际拍卖数据和调查数据，分析DNA档案信息对纯种公牛买家支付意愿的影响，发现DNA信息并未显著影响买家偏好，而传统指标如预期后代差异仍起主导作用。
Abstract DNA profile information has begun appearing in purebred bull auction catalogs; however, the value of this information is as of yet unknown. This study uses data from actual bull sales at a test station and combines it with stated‐preference survey data to determine the value of the DNA profile information. Consistent with previous research, we find that expected progeny differences (EPDs), test performance, and ultrasound information significantly influence bull‐buyers’ willingness‐to‐pay. The newer DNA profile information, however, was unrelated to buyers’ preferences. Methodologically, we find statistically significant differences (but highly correlated willingness‐to‐pay values) across the stated and revealed preference data sources.
