英文文献：Consumer acceptance and valuation of beef that has been tested for BSE-消费者接受和评估的牛肉已检测疯牛病
英文文献作者：Cranfield, John A.L.
英文文献摘要：
In light of the discovery of BSE infected cattle in Canada in 2003, a number of efforts have been undertaken to ensure the safety of beef produced in Canada. Recent discussion has focused on testing live cattle for the BSE prion. This paper investigates consumer acceptance and valuation of beef from live cattle that have been tested for BSE. Using data from an internet-?‐based survey of English speaking Canada, single bound estimates of WTP are measured. Expected WTP is 43 per cent for the entire sample, but ranges from 52 per cent for respondents with a high purchase intention to 28 per cent for those with less than a high purchase intention. Nevertheless, the proportion of respondents who were predicted to purchase a tested beef product was small, and ranged from 21 per cent for the high purchase intention respondents to eight per cent for the low/medium intention respondents. While respondents appear willing to pay for beef that has been tested for BSE, the market for such products is small.
鉴于2003年在加拿大发现了感染疯牛病的牛，已采取若干措施确保加拿大生产的牛肉的安全。最近的讨论集中在对活牛进行疯牛病朊病毒检测上。本文调查了消费者对已检测过疯牛病的活牛所产牛肉的接受程度和价值。利用一项以互联网为基础的加拿大英语国家的调查数据，测量了世界贸易目标的单界估计值。在整个样本中，预期折返率为43%，但在高购买意愿的受访者中为52%，而在低购买意愿的受访者中为28%。然而，预测购买测试牛肉产品的受访者比例很小，购买意愿高的受访者占21%，而购买意愿低/中的受访者占8%。尽管受访者似乎愿意为检测过疯牛病的牛肉买单，但这类产品的市场很小。
