A Manhattan search algorithm to minimize artificial neural network error function is outlined in this paper. From an existing position in Cartesian coordinate, a search vector moves in orthogonal directions to locate minimum function value. The search algorithm computes optimized step length for...

Categories or tags that appear in faceted search interfaces which are representative of an information item, rarely convey unexpected or non-obvious associated concepts buried within search results. No prior research has been identified which assesses the usefulness of discriminative search term...

For a user who is unfamiliar with a target domain, the first step to conduct an exploratory search task is to go over a learning phrase, which means to learn from the search results to acquire basic domain knowledge. Since lots of search results could be returned by a search engine, and usually...

Colour and visuals are used extensively by the advertisers of different product categories to attract consumer attention and create favourable attitude. Based on this premise, the present study aimed to explore the effect of colour and relative product size on the consumer attitudes...

We conduct a field study in a U.S. health insurance firm to examine how product customization affects the firm's cost to serve customers through its call center. In our setting, the product is a complex health insurance plan. The firm incurs substantial costs in serving the customers through its...

Building on Kihlstrom and Mirman (Journal of Economic Theory, 8(3), 361–388, <CitationRef CitationID="CR4">1974</CitationRef>)’s formulation of risk aversion in the case of multidimensional utility functions, we study the effect of risk aversion on optimal behavior in a general consumer’s maximization problem under uncertainty. We...</citationref>

Substitution decisions have been examined from a variety of perspectives. The economics literature measures cross-price elasticity, operations research models optimal assortments, the psychology literature studies goals in conflict, and marketing research has examined substitution-in-use, brand...

This paper describes the use of a marketing science model by Jetstar, a subsidiary of Australia's leading airline, Qantas, to effectively and profitably compete in the low-cost carrier marketplace. We trace the evolution of the Jetstar strategy from a baseline calibration of its initial...

We present a theory of context-dependent choice in which a consumer's attention is drawn to salient attributes of goods, such as quality or price. An attribute is salient for a good when it stands out among the good's attributes, relative to that attribute's average level in the choice set (or...

In this paper I review the evidence from marketing and psychology literature about the purchase behavior of consumers. I concentrate on the characteristics of the choice process, choice of the external information source and nature of the information obtained from these sources. The impact of...
