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...

In this paper we examine the performance of theories of decision making under uncertainty/ambiguity from the perspective of their descriptive and predictive power, taking into account the relative parsimony of the various theories. To this end, we employ an innovative experimental design which...

This paper studies the attitude of non-professional investors towards financial losses and their decisions concerning wealth allocation among consumption, risky, and risk-free financial assets. We employ a two-dimensional utility setting in which both consumption and financial wealth...

We report on an experimental study with real-world politicians. These political experts face political choice problems under risk and probability. Thus, we test the frequently observed violations of rational choice theory -the reference point effect, loss aversion, framing effects, and the...

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...

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...

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...

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...
