We consider the design of mechanisms for multi-sided exchanges that interact with strategic players—some of which have multi-dimension strategic spaces or are represented by mediators. Players act to optimize their own utilities. The mechanism designer, on the other hand, aims to optimize a social goal, i.e., the gain from trade. As the mediators control the information flow from their players ...

This paper starts with a re-examination of Piccione and Rubinstein’s [Games Econ. Behav. 20 (1997) 3] Absent-Minded Driver problem, and suggests a novel interpretation of Aumann, Hart and Perry’s [Games Econ. Behav. 20 (1997) 102] notion of action-optimality. We then consider several variants of the original problem in which the assumption that the player’s information sets partition the set of...

We propose a two-layer neuromorphic architecture by which motion field pattern, generated during locomotion, are processed by template detectors specialized for gaze-directed self-motion (expansion and rotation). The templates provide a gaze-centered computation for analyzing motion field in terms of how it is related to the fixation point (i.e., the fovea). The analysis is performed by relatin...

A letter or a three-dimensional shape was presented in the center of the visual field. Following the off-set of this stimulus either a comparison letter or a three-dimensional shape was flashed briefly in either the right or left visual field. The subject's task was to respond SAME, or DIFFERENT. The stimuli could be in the same plane, rotated in two dimensions (letters) or in three dimensions ...

We give an alternative proof of Madsen-Weiss’ generalized Mumford conjecture. Our proof is based on ideas similar to Madsen-Weiss’ original proof, but it is more geometrical and less homotopy theoretical in nature. At the heart of the argument is a geometric version of Harer stability, which we formulate as a theorem about folded maps.
