Although whole turkeys served at Thanksgiving are the ubiquitous kickoffs to the US winter holiday season, much remains unknown about shopping behaviors for holiday food items. Given the once-a-year purchase of the whole turkey for most households, collecting data about demand and preferences necessitated the collection of data during the week before Thanksgiving, while turkey shopping was at the forefront of consumers' minds. Despite a self-reported confidence in cooking turkeys, many respondents indicated they thawed frozen meat using improper methods. Ninety-five percent of respondents indicated that they consumed meat; 89% of respondents who consumed meat or had someone in the household who did, indicated they had purchased turkey products. Positive willingness to pay (WTP) was found for all attributes of whole turkeys studied: free range, fed a vegetarian diet, hormone use not permitted, and antibiotic use not permitted. Mean estimated WTP for free range ranged from $0.37/lb for industry verified free range to $0.74/lb for USDA verified free range; although those 2 estimates were not statistically different from each other, they were both statistically different from zero. The statistically significant estimated mean WTP for hormone use not permitted ranged from $0.85/lb for industry verification to $1.35 for USDA verification but were again not statistically different from each other. Mean WTP estimates, which were statistically significant but not different from one another for antibiotic use not permitted, ranged from $0.62/lb for industry certification to $0.72 for retailer certified. Turkeys certified to be fed a vegetarian diet had a mean WTP estimate of $0.39/lb for retailer verification to $0.60/lb for USDA verification; those mean WTP estimates were not statistically different from each other but were each statistically different from zero. Social desirability bias, which can be defined as the relative over-reporting of one's own goodness, was detected with respect to self-reported holiday eating and healthfulness statements. Relationships were found between social desirability bias, gender, and age for holiday eating statements using a seemingly unrelated regression.
尽管在感恩节供应整只火鸡是美国冬季假期的常见开端,但对于假日食品的购物行为,仍有许多未知之处。鉴于大多数家庭每年只购买一次整只火鸡,为了收集有关需求和偏好的数据,有必要在感恩节前一周收集数据,因为此时火鸡购物是消费者关注的焦点。尽管受访者自我报告对烹饪火鸡有信心,但许多人表示他们使用了不当的方法来解冻冷冻肉。95%的受访者表示他们食用肉类;89%的食用肉类或家中有人食用肉类的受访者表示,他们购买了火鸡产品。研究表明,所有整只火鸡的属性都具有正的支付意愿(WTP):自由放养、素食喂养、不允许使用激素和不允许使用抗生素。自由放养的平均估计 WTP 从行业验证的自由放养每磅 0.37 美元到 USDA 验证的自由放养每磅 0.74 美元不等;尽管这两个估计值彼此之间没有统计学差异,但都与零有统计学差异。不允许使用激素的估计 WTP 平均值从行业验证的每磅 0.85 美元到 USDA 验证的每磅 1.35 美元不等,但彼此之间没有统计学差异。不允许使用抗生素的平均 WTP 估计值在统计学上是显著的,但彼此之间没有差异,从行业认证的每磅 0.62 美元到零售商认证的每磅 0.72 美元不等。经认证以素食喂养的火鸡的平均 WTP 估计值从零售商验证的每磅 0.39 美元到 USDA 验证的每磅 0.60 美元不等;这些平均 WTP 估计值彼此之间没有统计学差异,但都与零有统计学差异。社会期望偏差,可以定义为相对过高地报告自己的优点,在关于节日饮食和健康的自我报告中被发现。使用似乎不相关的回归,发现社会期望偏差、性别和年龄与节日饮食陈述之间存在关系。
