We define a behavioral concept of relevance in the context of decision making under uncertainty.  We argue that this concept provides a sensible answer to the question "What probabilistic environments do an individuals' preferences reveal as mattering to her decisions?" under a symmetry...

This introductory article reviews the main themes relating to the development of new knowledge-based economies. After placing their emergence in historical perspective and proposing a theoretical framework which distinguishes knowledge from information, the authors characterize the specific...

Epstein (2009) describes three Ellsberg-style thought experiments and argues that they pose difficulties for the smooth ambiguity model of decision making under uncertainty developed by Klibanoff, Marinacci and Mukerji (2005).  We revisit these thought exeperiments and find, to the contrary,...

Are foundations of models of ambiguity-sensitive preferences too flawed to be usefully applied to economic models?  Al-Najjar and Weinstein (2009) say such is indeed the case.  In this paper, first, we point out that many of the key arguments by Al-Najjar and Weinstein do not apply to quite a...

This paper provides a positive theory about the contractual form of procurement contracts under cost uncertainty. However, while the cost of manufacture is uncertain it can be reduced by an amount depending on the extent of effort exerted by the agent. The effort exerted by the agent is not...

A `framing` effect occurs when an agent`s choices are not invariant under changes in the way a choice problem is formulated, e.g. changes in the way the options are described (violation of description invariance) or in the way preferences are elicited (violation of procedure invariance). In this...

This paper examines the impact of mass media and information and communications technologies (ICT) as knowledge-based infrastructures on economic development. The results strongly suggest that both mass media and ICT penetration are negatively associated with corruption. This result holds across...
