We study axiomatically the problem of obtaining an expected utility representation for a potentially incomplete preference relation over lotteries by means of a set of von Neumann-Morgenstern utility functions. It is shown that, when the prize space is a compact metric space, a preference...

Selfish utilitarianism, neo-classical economics, the directive of short-term income maximization, and the decision tool of cost-benefit analysis fail to protect our species from the significant risks of too much consumption, pollution, or population. For a longer-term survival, humanity needs to...

Personal decisions about health hazards are the main cause of impaired health and premature death. People smoke and eat too much and exercise too little. The lack of preventive efforts is surprising given their proven effectiveness. Arrow's (1963) classical paper suggested that moral hazard...

Two studies attempted to discriminate between a situationaleconomic and a cultural explanation for the recently reported finding that Chinese from the People's Republic of China (PRC) are more risk-seeking than Americans. Both studies compared American and Chinese proverbs related to risk and...

In this article, we describe a multistudy project designed to explain observed cross-national differences in risk taking between respondents from the People's Republic of China and the United States. Using this example, we develop the following recommendations forcross-cultural investigations....

Prospect theory's S-shaped weighting function is often said to reflect the psychophysics of chance. We propose an affective rather than psychophysical deconstruction of the weighting function resting on two assumptions. First, preferences depend on the affective reactions associated with...

Given the possibility to modify the probability of a loss, will a profit-maximizing insurer engage in loss prevention or is it in his interest to increase the loss probability? This paper investigates this question. First, we calculate the expected profit maximizing loss probability within an...
