We present a theory of choice among lotteries in which the decision maker's attention is drawn to (precisely defined …) salient payoffs. This leads the decision maker to a context-dependent representation of lotteries in which true probabilities … are replaced by decision weights distorted in favor of salient payoffs. By endogenizing decision weights as a function of …

This concept allows us to bring together and partially …

In this paper, we assess the degree to which four of the most commonly used models of risky decision making can explain … utility model, a subjective expected utility model and a probability-transform model. We find that the four models considered … explain the decision-making behavior of the majority of our subjects. Surprisingly, we find that the choice behavior of the …

We study the problem of a policymaker who seeks to set policy optimally in an economy where the true economic structure is unobserved, and he optimally learns from observations of the economy. This is a classic problem of learning and control, variants of which have been studied in the past, but...
