and Implications A method was developed to calculate economic values for pork quality traits for use in genetic selection. The method considers the normal variability of pork quality traits within a herd or population. The parameters required for this method are the mean, standard deviation, and range of the quality trait within the herd or population, and the relationship of the level of the q...

The effects of baking with broccoli powder on the consumer perception and sensory characteristics were investigated using a model system of cookies incorporated with broccoli powder as a value-added food ingredient. Broccoli powder was incorporated into cookie dough at 5 levels (0%, 1%, 2%, 3%, and 4%, w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheet...

Aggregation without the Aggravation? Nonparametric Analysis of the Representative Consumer In the tradition of Afriat (1967), Diewert (1973) and Varian (1982), we provide a revealed preference characterisation of the representative consumer. Our results are simple and complement those of Gorman (1953, 1961), Samuelson (1956) and others. They can also be applied to data very readily and without ...

Our paper makes use of the Analytical Hierarchy Process (AHP) in order to derive the willingness to pay (WTP) for complex goods with a range of attributes and attribute levels. Weights obtained from the AHP are used to decompose the aggregate WTP obtained from Contingent Valuation (CV) in a hypothetical simulated market. The empirical analysis uses consumer-level questionnaires to elicit inform...

Colour of food is an integral part of our culture and enjoyment of life. Colour is also an important parameter for sensory analysis and consumer preference. However using synthetic colour could be harmful for health of a consumer. Therefore in today’s progressive world a shift from synthetic to biocolour is observed. The present article will enable to understand the what are biocolour, how they...

This paper examines elements of the complex place/role/influence of psychology in the history of consumer choice theory. The paper reviews, and then challenges, the standard narrative that psychology was “in” consumer choice theory early in the neoclassical revolution, then strictly “out” during the ordinal and revealed preference revolutions, now (possibly) back in with recent developments in ...

There has been relatively little research on consumer usage of text messages and Instant Messenger, whilst mobile phones and email usage have been more widely addressed. This study compares consumer usage of four communication channels: Instant Messenger, text messages, mobile phones and email, with the focus on consumer choice of communication medium. This research used grounded theory and foc...

The globalization of market has brought considerable foreign goods to Chinese consumers. The competition between domestic and foreign corporations became more and more intense during last decades. This study focuses on how consumer ethnocentrism influences the preference for domestic goods among Chinese consumers. The data were collected through questionnaire from 501 middle school students. Th...

We visit the following problem: For a ‘generic’ model of consumer choice (namely, distributions over preference lists) and a limited amount of data on how consumers actually make decisions (such as marginal preference information), how may one predict revenues from offering a particular assortment of choices? This is a central problem in operations research and marketing. We present a framework...

We visit the following fundamental problem: For a ‘generic’ model of consumer choice (namely, distributions over preference lists) and a limited amount of data on how consumers actually make decisions (such as marginal preference information), how may one predict revenues from offering a particular assortment of choices? This problem is central to areas within operations research, marketing and...
