This paper considers equilibrium directed search with a finite number of heterogeneous workers and firms, where firms compete in direct mechanisms. Unlike previous findings, Nash equilibrium here does solve the problem of coordination failure. Restricting the match value function to be supermodular, and that firms use truthful strategies also imply positive assortative matching and decentralize...

Background: Pro-inflammatory cytokines are associated with systemic inflammatory responses. Objective: To investigate the levels of pro-inflammatory cytokines (IL-1b, IL-6, and TNF-a) in patients with non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH) compared to healthy individuals. Methods: This case-control study was c...

conclusions our comprehensive literature review showed that our study was the first investigation in iran and the region, which determined the prevalence of nafld based on tissue diagnosis. we believe that the prevalence of nafld/nash in our donors can represent the overall prevalence in this age group in iran. results among 116 cases, two were diagnosed as probable nash. there was a significan...

We consider a family of population game dynamics known as Best Experienced Payoff Dynamics. Under these dynamics, when agents are given the opportunity to revise their strategy, they test some possible strategies fixed number times. Crucially, each strategy is tested against new randomly drawn set opponents. The revising agent then chooses whose total payoff was highest in test, breaking ties a...

In the single-peaked domain, median rule is strategy-proof but not implementable in (Bayes–)Nash equilibrium by its associated direct mechanism. We define value-based mechanism that implements domain under complete and incomplete information. Such a selects of profile different values announced agents (i.e., ignoring redundant announcements). The does depend on agents’ beliefs (in line with rob...

The price of anarchy is by now a standard measure for quantifying the inefficiency introduced in games due to selfish behavior, and is defined as the ratio between the optimal outcome and the worst Nash equilibrium. However, the price of anarchy is not even defined in games that admit no Nash equilibrium. We propose the dynamic inefficiency measure, which quantifies the average inefficiency int...

We study the design of core-selecting payment rules for combinatorial auctions (CAs), a challenging setting where no strategyproof rules exist. Unfortunately, under the rule most commonly used in practice, the Quadratic rule Day and Cramton (2012), the equilibrium strategies are far from truthful. In this paper, we present a computational approach for nding good core-selecting payment rules. We...

conclusions il6 and il8 gene polymorphisms have no role in nash pathogenesis and liver fibrosis process, but presence of the a/a genotype in the il8 gene is associated with disease progression. patients and methods consecutive patients with biopsy proven nash and age- and gender-matched healthy individuals with normal liver function tests and normal ultrasonography were enrolled in the study. h...

This paper reports an experimental study on three well-known solutions for problems of adjudicating con‡icting claims: the constrained equal-awards, the proportional, and the constrained equal-losses rules. We …rst let subjects play three games designed such that the unique equilibrium allocation coincides with the recommendation of one of these three rules. In addition, we let subjects play an...
