Characterizations of Nash equilibrium, correlated equilibrium, and rationalizability in terms of common knowledge of rationality are well known [Aumann 1987; Brandenburger and Dekel 1987]. We show how to get analogous characterizations of sequential equilibrium and (trembling hand) perfect equilibrium, as a consequence of recent results of Halpern [2009]. Arguably the major goal of epistemic ga...
Vickrey (1961) provided a game-theoretic analysis of the single-unit second price auction and showed that bidders have an incentive to set their bids equal to their valuations. Groves (1973), Clarke (1971), and Forsythe, Isaac, and Palfrey (1989) generalized this analysis for public goods and multiple unit auctions. The cornerstone of the Vickrey auction is its pricing rule by which the winner'...
We consider a fundamental game theoretic problem concerning selfish users contributing packets to an M/M/1 queue. In this game, each user controls its own input rate so as to optimize a desired tradeoff between throughput and delay. We first show that the original game has an inefficient Nash Equilibrium (NE), with a Price of Anarchy (PoA) that scales linearly or worse in the number of users. I...
Our regulatory institutions, broadly taken, include our moral norms and models and have not fully adapted to significant changes in data mining technology. For example, we suggest that the metaphors — Big Brother and “data mining” itself — commonly used to describe and assess this new technology are deficient, overemphasizing social discipline by the state and the passivity of the so-called dat...
Researchers often find that nonlinear regression models are more relevant for their studies than are linear ones, and are thus often in a position of requiring efficient designs for a given nonlinear model. A common shortcoming of most optimal designs for nonlinear models used in practical settings, however, is that these designs typically focus only on first-order parameter variance or predict...
The diffusion of mobile services is one of important technological phenomena of the twenty-first century (Dholakia & Dholakia, 2003). According to the International Telecommunication Union,1 the number of mobile service users had exceeded 1.5 billion individual subscribers by early 2005. This represents around one-quarter of the world’s population. The introduction of .mobi, a new toplevel doma...
We provide a Bayes-Nash equilibrium analysis of the simultaneous ascending auction (SAA) when local bidders interested in a single item compete against global bidders interested in aggregating many items. We first assume that each local bidder values only a specific item, e.g. the license for the region where it has monopoly power, and that global bidders’ valuation functions are convex. For th...
Introduction: This research investigated the effects of violent and football video games on cognitive functions, cortisol levels, and brain waves. Methods: A total of 64 participants competed in a single-elimination tournament. Saliva samples of all players were obtained before and after the games for the assessment of cortisol levels. The cognitive performances of the players were also assess...
cooperation is the foundation of many protocols in wireless networks. without cooperation, the performance of a network significantly decreases. hence, all nodes in traditional networks are required to cooperate with each other. in this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whether to cooper...
An inspection game is here a non-cooperative two-person-game between an inspector and an inspectee. It models a situation where the inspector controls the inspectee who has an incentive to violate certain legal obligations. A recent survey of inspection games applied to data verification, for example in nuclear material safeguards, is given in [1]. Dresher [2] described a sequential inspection ...
