Slicing,Dicing, Spicing,and Pricing: Factors Influencing Purchase and Consumption of Fresh Potatoes

To better understand potential reasons for a North American decline in fresh potato consumption, a region-wide survey (n = 1009) was undertaken in eastern Canada. Results were examined comparing high- and low-frequency potato users on a variety of factors, including beliefs, attitudes, barriers, needs, and satisfaction with potatoes. Respondents indicated positive perceptions pertaining to potato nutrition, taste, preparation, and overall enjoyment. Multiple logistic regression analysis suggested two variables—age and the perceived importance of potatoes for the everyday meal—were strong predictors of high versus low frequency of potato consumption. Respondents judged the ability to see the potato in the package, potato firmness, and locally produced as point-of-purchase characteristics particularly important when buying fresh potatoes. However, respondents also indicated that their needs were not fully met and expressed relatively low levels of satisfaction when purchasing potatoes. Based on the results, suggestions are provided for improving the marketing of fresh potatoes.

Cross-sectional surveys: Inferring total eventual time in current state using only elapsed time-to-date

We focus on snapshot surveying of sub-populations whose members are in a temporary state and where one of the questions asked is the elapsed time already spent in that state. From these answers we develop probabilistic and statistical procedures to estimate the distribution of total time that will eventually be spent in that state by any random individual who enters the state. The method relies on a selection bias often found in temporal sampling, sometimes called “random incidence” or “longevity bias.” We develop results for several types of sampling, including random and fixed times of surveying, random and fixed times of entering the state, and sampling only those who have already spent some minimal specified time in the targeted state. An example with post-doc data is included to demonstrate the steps.

中国城镇家庭能源贫困评估*——基于微观调查数据的研究

我国扶贫工作重点已进入新阶段,从消除绝对贫困向缓解发展不平衡、不充分的相对贫困转变,从解决收入贫困向解决多维贫困转变,从重点解决农村贫困问题向统筹城乡扶贫转变。能源是人民生活质量的重要指标,能有效反映福利水平。了解我国城镇家庭能源消费的基本特征、准确测度能源贫困水平与分布,有助于为今后扶贫工作提供资料基础和科学管理依据。本文构建消费者能源消费决策分析框架,并运用第一次中国家庭能源消费调查数据,考察居民收入与能源消费之间的关系,并对中国城镇家庭能源贫困状况进行测度。研究发现,居民收入与能源消费之间存在S型非线性关系,能源价格、家庭特征、地域特征等因素在能源消费决策中都发挥重要影响。我国城镇家庭相对能源贫困较为严重,主要表现为能源可支付性问题。能源贫困率在20%左右,其中电力贫困程度更为严重,超过25%。家庭收入增长、户主受教育程度提高、城市电力基础设施的普及、城市环境规制水平的提升会显著降低城镇家庭陷入能源贫困的可能性,而电力价格上涨会显著增加城镇家庭陷入能源贫困的概率。
