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 ...
