This paper analyzes the dynamic stability of moral codes in a two population trust game. Guided by a moral code, members of one population, the Trustors, are willing to punish members of the other population, the Trustees, who defect. Under replicator dynamics, adherence to the moral code has unstable oscillations around an interior Nash Equilibrium (NE), but under smoothed best response dynami...

This paper applies quantal response equilibrium (QRE) models (McKelvey and Palfrey, Games and Economic Behavior 10 (1995), 6-38) to a wide class of symmetric coordination games in which each player's best response is determined by an order statistic of all players' decisions, as in the classic experiments of Van Huyck, Battalio, and Beil (American Economic Review 80 (1990), 234-248; Quarterly J...

background and aim : the quick speech in noise (q-sin) test have been designed to evalu­ate individuals’ ability to recognize speech in noise. this study established to evaluate the test-retest reliability and equivalency of the five test lists of the persian q-sin test in subjects with sensory hearing loss (shl) and normal hearing individuals. methods : this cross-sectional study was per­forme...

This paper studies properties of equilibrium selection based on quantal response equilibrium (QRE) models (McKelvey and Palfrey, Games and Economic Behavior 10 (1995), 6-38). In a QRE, the chances of playing sub-optimal strategies by mistakes are proportional to expected payo ̄ s, and QRE produces a distinct prediction from other noise-based re§ nements. A selection based on QRE coincides with r...

We analyze data from the second-price maximum-value auction experiment reported in Ivanov, Levin and Niederle (2010) in order to investigate the extent to which the winner’s curse can be explained by quantal response, in combination with diffferent assumptions about equilibrium (QRE) or nonequilibrium beliefs (QCH or QCE). We find a close correspondence between the theoretical predictions of th...

This research is on improving the efficiency of our previous work for removing semantically equivalent expressions in program search results.

in this paper we investigate a nonlinear evolution model described by the rosenau-kdv equation. we propose a three-level average implicit finite difference scheme for its numerical solutions and prove that this scheme is stable and convergent in the order of o(τ2 + h2). furthermore we show the existence and uniqueness of numerical solutions. comparing the numerical results with other methods in...

Viability of Bordetella pertussis was preserved when glycerol broth suspensions were quick frozen and stored at -70 C for as long as 45 months.

This paper applies quantal response equilibrium (QRE) models (McKelvey and Palfrey, 1995, Games and Economic Behavior) to ultimatum bargaining games. When the strategy space is discrete, as the noise vanishes, the QRE of the normal-form representation converges to a Nash equilibrium in which an equilibrium o er is between 0 and a half of the pie while the QRE of the extensive-form representatio...
