Many introductory microeconomics textbook authors derive the law of demand from the assumption of diminishing marginal utility. Authors of intermediate and graduate textbooks derive demand from diminishing marginal rate of substitution and ordinal preferences. These approaches are not...

In its present formulation the Human Development Index (HDI) is a measure of the well-being of nations considering two fixed reference values for each indicator, the so-called fixed goals of development, as normalization parameters. As is well known, the HDI is insensitive to the relative...

This paper presents a review of adaptation concepts at the evolutionary, environmental, neural, sensory, mental and mathematical levels, including Helson’s and Parducci’s theories of perception and category judgments. Two kinds of adaptation can be clearly distinguished. The first, known as...

This paper examines the relationship between question order and sensitivity to scope in a large-scale web-based stated preference survey using an Internet panel. Results are presented from a contingent valuation survey in which each individual was asked to value two independent gains in life...

This study elicits individual preferences for reducing morbidity and mortality risk in the context of an infectious disease (campylobacter) using choice experiments. Respondents are in the survey asked to choose between different policies that, in addition to the two health risks, also vary with...

The paper reports the results of a survey designed to elicit probability judgements for different types of events: ‘pure chance’ events, for which objective probabilities can be calculated; ‘public’ events, about which there may be some discussion in social groups and the media; and...

In this article, the authors examine the cognitive mechanics involved in keeping prices in short-terme memory for subsequent recall. Consumers code and store prices verbally, visually, and in terms of their magnitude. The encoding used influences immediate recall performance. The memorability of...
