We study optimal public health care rationing and private sector price responses. Consumers differ in their wealth and illness severity (defined as treatment cost). Due to a limited budget, some consumers must be rationed. Rationed consumers may purchase from a monopolistic private market. We consider two information regimes. In the first, the public supplier rations consumers according to thei...

Data from 5391 adults between 20 and 50 years of age were analyzed to determine the magnitude of cross-sectional age-related effects on a set of cognitive variables within this age range, and to examine the degree of independence of age-related influences on different variables. Scores on a test of vocabulary increased about 0.05 standard deviation units per year across this age range, while sc...

To determine visual preference and value for fresh beef steaks differing in marbling level and color, consumers in Chicago and San Francisco (n = 124 per city) evaluated two pairs of steaks in a retail case. Steaks differing in marbling level (Modest/Moderate vs. Slight) and color (bright, cherry-red vs. dark red) were purchased at retail stores in each city. Consumers selected their preferred ...

Market segmentation divides the market into small groups of consumers who share similar characteristics. As all consumers within the same group have a common profile, marketing strategies can be adapted to target a specific type of consumer. Owing to the rapid changes in today’s society, consumer lifestyle has become the ideal criterion for market segmentation. In this study, we employed the fo...

Use of stable isotope ratios to trace pathways of organic matter among consumers requires knowledge of the isotopic shift between diet and consumer. Variation in trophic shift among consumers can be substantial. For data from the published literature and supplementary original data (excluding fluid-feeding consumers), the mean isotopic shift for C was +0.5 0.13‰ rather than 0.0‰, as commonly as...

In E-commerce, purchase decisions of consumers are often strongly influenced by people who consumers know and trust, and word-of-mouth (WOM) is the most important factor when consumers are making a purchase decision. Many online consumers tend to wait for the opinions of early consumers before making a purchase decision to reduce the risk of buying products. So numerous E-commerce websites prov...

Consumers differ in their preferences under temptation. When all consumers are tempted...
