El artículo discute la exposición de Santiago y Cante (2009) de la teoría de la decisión racional (TDR) y el modelo de utilidad esperada y controvierte su afirmación de acuerdo con la cual la Prospect Theory (PT) de Kahneman y Tversky pone en riesgo el estatus normativo de la TDR. Para ello...

This paper tests new "independence" properties to compare three models of risky decision making. According to the rank-affected multiplicative (RAM) weights model, all three properties should be satisfied; according to the transfer of attention exchange (TAX) model, two should be satisfied and one...

We develop a belief-based account of decision under uncertainty. This model predicts decisions under uncertainty from (i) judgments of probability, which are assumed to satisfy support theory; and (ii) decisions under risk, which are assumed to satisfy prospect theory. In two experiments,...

The Cumulative Prospect Theory (CPT) uses piecewise value functions instead of consumer utility and provides alternative assumptions for investment behaviour approximated by power value function. In this study, our aim to find a generalized value function that will make the value function...

When individuals choose among risky alternatives, the psychological weight attached to an outcome may not correspond to the probability of that outcome. In rank-dependent utility theories, including prospect theory, the probability weighting function permits probabilities to be weighted...

The most distinctive prediction of prospect theory is the fourfold pattern (FFP) of risk attitudes. People are said to be (1) risk-seeking over low-probability gains, (2) risk-averse over low-probability losses, (3) risk-averse over high-probability gains, and (4) risk-seeking over...

Empirical studies of fishers’ preferences have found that most fishers are risk-averse, while expected-utility theory predicts risk neutrality even for sizable stakes. We test this prediction using data from a stated choice experiment with Swedish commercial fishers. Our results show that...

The insurance industry has an essential economic importance.In spite of the great progress,we have to emphase that the existing theoretic models cannot entirely explain the mechanism of the insurance market and of its decisional process,especially in the case of the events with low...
