This paper provides a multiple-priors representation of ambiguous beliefs à la Ghirardato, Maccheroni, and Marinacci (2004) and Nehring (2002) for any preference that is (i) monotonic, (ii) Bernoullian, i.e. admits an affine utility representation when restricted to constant acts, and (iii) suitably continuous. Monotonicity is the main substantive assumption: we do not require either Certainty ...

The analysis of extensive-form games involves assumptions concerning players’ beliefs at histories off the predicted path of play. However, the revealed-preference interpretation of such assumptions is unclear: how does one elicit probabilities conditional upon events that have zero ex-ante probability? This paper addresses this issue by proposing and axiomatizing a novel choice criterion for a...

J Appl Physiol 91: 2823–2830, 2001.—Estrogen replacement increases risk of venous thrombosis. In this study, we determined responses in vitro to platelets and platelet products in veins from adult male and intact and ovariectomize...

Wrist stiffness has been shown to have a greater effect on wrist dynamics than inertia and damping for all but the fastest wrist rotations [1]. Therefore, making coordinated wrist rotations requires that humans predict and compensate for the effects of wrist stiffness. Because wrist stiffness is anisotropic (with greater stiffness in radial-ulnar deviation than flexion-extension), some movement...

Rai¤a (1961) has suggested that ambiguity aversion will cause a strict preference for randomization. We show, however, that dynamic consistency implies that individuals will be indi¤erent to ex ante randomizations. On the other hand, it is possible for a dynamically-consistent ambiguity averse preference relation to exhibit a strict preference for some ex post randomizations. We argue that our ...

It is one of the central doctrines for ”rational” decision making that an agent should be forward-looking and not be bound by things already gone. We argue that this is not an appealing principle for collective decision making, and that things already gone have necessary and substantive roles. We consider a dynamic process of social welfare orderings explicitly, and propose a discipline which i...

In the classic Anscombe and Aumann decision setting, we give necessary and sufficient conditions that guarantee the existence of a utility function u on outcomes and an ambiguity index c on the set of all probabilities on the states of the world such that, for all acts f and g, f % g ⇔ min p (∫ u (f) dp+ c (p) ) ≥ min p (∫ u (g) dp+ c (p) ) . The function u represents the decision maker’s risk ...

UNLABELLED Compared to adult medicine, drug use in children is not extensively researched. OBJECTIVE The objective of present study is to find out drug prescribing pattern in the Department of Pedodontics and Preventive Dentistry and Orthodontics in teaching hospitals in Rajasthan, India. METHODS A prospective study was conducted in June 2011. A total of 619 prescriptions were collected ran...
