We study stochastic choice as the outcome of deliberate randomization. After first deriving a general representation of a stochastic choice function with such property, we proceed to characterize a model in which the agent has preferences over lotteries that belong to the Cautious Expected...

In this paper we integrate the literature on decision quality with considerations specific to boards of directors. In order to maximize the value of their decisions, boards of directors must look beyond their legal obligations and incorporate business ethics and the latest developments in...

Kenneth Arrow and Karl Borch published several important articles in the early 1960s that can be viewed as the beginning of modern economic analysis of insurance activity. This chapter reviews the main theoretical and empirical contributions in insurance economics since that time. The review...

The principle of indifference states that events should be assigned equal probabilities if no reason can be given for regarding one event as more likely than another. This paper provides a normative argument for the principle of indifference based on a new formal model of decision under...

Models can be wrong and recognising their limitations is important in financial and economic decision making under uncertainty. Robust strategies, which are least sensitive to perturbations of the underlying model, take uncertainty into account. Finding the explicit set of alternative models...

This paper examines the preference-based approach to the identification of beliefs. It focuses on the main problem to which this approach is exposed, namely that of state-dependent utility. First, the problem is illustrated in full detail. Four types of state-dependent utility issues are...

This Article argues that information gaps—pockets of information that are pertinent and knowable but not currently known—are a byproduct of shadow banking and a meaningful source of systemic risk. It lays the foundation for this claim by juxtaposing the regulatory regime governing the shadow...

Decision-makers typically rely on informative starting points that are somewhat incorrect and then attempt to make appropriate adjustments. Such reliance on informative starting points may be an optimal response of a Bayesian decision-maker who faces finite computational resources (Lieder et al...

We investigate experimentally preferences between different ambiguous processes generated by two-color Ellsberg urns. By providing symmetric information on urns with different numbers of beads and keeping the information on the most optimistic, pessimistic, and equal probability of winning...
