This paper studies the identification of the costs of simultaneous search in portfolio problems (Chade and Smith, 2006). We show that market shares data from a single market do not provide sufficient information to identify the search cost distribution in any interval, even if...

We study two aspects of globalization. It allows a decision-maker to go beyond his own local experience and to learn from other decision-makers in addressing common problems. This improves the identification and diffusion of best practices. It also provides extra information to `markets' that...

In this paper we study Markov Decision Process (MDP) problems with the restriction that at decision epochs only a finite number of given Markovian decision rules may be applied. The elements of the finite set of allowed decision rules should be mixed to improve the performance. The set of...

In experimental investigations of the effect of real incentives, accountability—the implicit or explicit expectation of a decision maker that she may have to justify her decisions in front of somebody else—is often confounded with the incentives themselves. This confounding of accountability...

This paper analyzes, for S-shaped value functions, the relations between loss aversion and perceptional risk aversion (i.e. computed with the perceived probability weights) in Cumulative Prospect Theory. We show that perceptional risk aversion for mixed sign lotteries is equivalent to weak loss...

This paper deals with utility (or value) function for reference dependent models. A new characterization of S-shaped utility functions displaying loss aversion is put forward. Then it is used to analyze some standard forms commonly used in the literature. It is shown that, unless some...
