Is higher status necessarily a signal of higher quality? Prior research on how status and quality can become decoupled has shown that social influence processes can lead to a low correlation between status and quality. Here we show that having high but not top status can be an indication of medium rather than high quality, even if top status indicates top quality. A formal model shows that such...

This paper studies an overlapping generations model with stochastic production and incomplete markets to assess whether the introduction of an unfunded social security system leads to a Pareto improvement. When returns to capital and wages are imperfectly correlated a system that endows retired households with claims to labor income enhances the sharing of aggregate risk between generations. Ou...

Group members often reason egocentrically, believing that they deserve more than their fair share of group resources. Leading people to consider other members' thoughts and perspectives can reduce these egocentric (self-centered) judgments such that people claim that it is fair for them to take less; however, the consideration of others' thoughts and perspectives actually increases egoistic (se...

Recent studies have suggested that current agent-based models are not sufficiently sophisticated to reproduce results achieved by human collaborative learning and reasoning. Such studies suggest that humans are diverse and dynamic when solving problems socially. However, despite their relevance to problem-solving, these two behavioral features have not yet been fully investigated. In this paper...

resilience as a psychological emotional mechanism is employed by the individuals when they are in stressful irritating situations to be able to resume their previous productive mental activities. it is a vital coping activity when students go through upsetting events, psychological breakdowns, academic failures, suffocating educational atmospheres, and undemocratic teaching techniques. the esse...

In this paper, a system of GIG/l/K queue is considered. The optimal system's capacity (K), when the system is optimized with respect to the benefit of the entire system (social optimization) and when the criterion for optimality is individual gains (individual optimization), is determined and compared. In social optimization, the system capacity is obtained through maximization of the syst...
