Tradeoffs between sensory attributes and organic labels: the case of orange juice

Researchers have investigated the role of sensory attributes and organic labels on consumers’ preferences and perceptions of food, but few has examined whether sensory attributes are relevant for consumers who prefer organic food and the extent to which sensory attributes influence consumer's marginal willingness to pay for organic food. The objective of this study is to determine how sensory attributes and organic label work together to influence consumer's stated preference and marginal willingness to pay for orange juice. To achieve this, we conducted a blind sensory evaluation of two orange juices followed by a discrete choice experiment to determine the extent to which consumer's stated preference for orange juice labelled as organic is affected by sensory experience preceding the choice experiment. Random parameter logit models and latent class conditional logit models are used to explain stated preference. Results indicate that the effect of sensory attributes on consumer's marginal willingness to pay differed by organic juice and conventional juice.

Prices of deep discount bonds and the Revenue Act of 1978: An evaluation of market response

This article explores the market response of deep discount corporate bonds to the reduction in the capital gains tax rate incorporated into the Revenue Act of 1978. Such tax change should have increased the desirability of assets acquired for capital gains potential, such as deep discount bonds. Examining a time series of prices and returns for a sample of deep discount corporate bonds and a control group of comparable duration and credit risk corporate bonds selling at or near par did indeed provide evidence of a market price reaction. Moreover, the price changes for the deep discount bonds occurred well in advance of the implementation of the tax change.

Estimating temporal trends in preferences measured by graded paired comparisons

A sizable marketing research literature on preference measurement, prediction, and explanation has thus far been more concerned with point estimates of preference than with consistent changes over time. Such temporal trends can be estimated using data collected from graded paired comparisons. An appropriate technique for deriving individual and group trend parameters is first described and then illustrated using data from an experiment dealing with aesthetic preferences. Suggestions are offered concerning its advantages and limitations for applications in marketing.

阶梯电价政策的居民节能意愿与节能效果评估--基于广东案例的研究

以广东省为例,基于粤东、粤西、粤北及珠三角典型地市的社会调查,统计分析阶梯电价政策对居民节能意愿及家庭用电的影响;同时运用广东省月度电力数据,构建ARIMA模型,定量研究政策实施的节能效果。研究表明,阶梯电价政策的实施对改善居民节能意愿有积极影响,并在短期内有明显的节能效果,但随着时间推移,节能效果有所减弱。为设计与完善相关政策,未来需要从节能意愿、经济激励等角度切入,提升政策的针对性、有效性。
