It is crucial to develop effective online product search tools to assist users to find the desired products and to make sound purchase decisions.

Viscusi (1978) shows how, in markets with quality uncertainty, perfect certification results in separation from top down due to an unraveling process similar to Akerlof (1970). De and Nabar (1991) argue that imperfect certification prevents unraveling so that equilibria with full separation do not exist. This note shows that, if one considers the buyers’ buying decision explicitly, a separating...

This paper presents the results of simulated trading on long time series price and share volume data for the Dow Jones Industrial Average and Standard and Poor’s 500 Index. Robust and systematic results demonstrate strong support for the effectiveness of the market trading heuristic of buying when one-day share trading volume spikes. Implementation of the methods is straightforward and may be r...

In this paper we present a software tool designed as a decision aid system for all actors being involved when buying or selling real state, client and realtor, where a main objective for the commercial is to concentrate the client preferences into few alternatives. Since the required previous analysis implies a number of fuzzy concepts, the general procedure here presented considers fuzzy logic...

Beef sire selection decisions have a major impact on future calf crops and ultimately on profitability. Using available selection tools can help make better bull buying choices. A critical place to start when beginning the herd sire selection decision process is to evaluate the cow herd(s) that the sires will service. From these herd assessments, profiles of desirable herd sires can be develope...

Descriptive theories of decision making are constrained by the need to explain the following behavioral phenomena: risk aversion, gambling, purchases of insurance, investment, the paradoxes of Allais and Ellsberg, intransitivity of preference, irregularities of choice, preference reversals, risk judgments, violations of branch independence, the difference between buying and selling prices, viol...

Many durable goods, particularly in the high technology sector of the economy, experience rapid quality improvement. As a result, replacement is typically due to obsolescence rather than breakdown, and replacement cycles are generally short. When these goods are vertically differentiated, consumers must make two important, inter-related choices upon making a purchase: what quality level to buy,...

In general, few studies have examined the influence of children and adolescents on family decision-making. This study evaluates the relative influence of children and adolescents on the purchasing decisions of families planning to buy both major/durable and minor/nondurable products. These family products are classified by product type, and the results from a sample of 2,402 children and adoles...
