We study the problem of finding an envy-free allocation of a cake to d+1 players using d cuts. Two models are considered, namely, the oracle-function model and the polynomial-time function model. In the oracle-function model, we are interested in the number of times an algorithm has to query the players about their preferences to find an allocation with the envy less than …. We derive a matchin...

We show that an asymptotic envy-freeness is a necessary condition for a form of robust approximate implementation in large economies. JEL classi cation numbers: D78, D51, D71 Envy-Freeness and Implementation in Large Economies Matthew O. Jackson Ilan Kremer

While perfectionism is widely considered to influence risk for eating disorders, results of longitudinal studies are mixed. The goal of the current study was to investigate a more complex model of how baseline perfectionism (both high personal standards and self-critical evaluative concerns) might influence change in risk status for eating disorders in young adolescent girls, through its influe...

We consider random assignment of multiple indivisible objects. When each agent receives one object, Bogomolnaia and Moulin (2001) show that the probabilistic serial mechanism is ordinally efficient, envy-free and weakly strategy-proof. When each agent receives more than one object, we propose a generalized probabilistic serial mechanism that is ordinally efficient and envy-free but not weakly s...

Social networking sites (SNS) have grown to be one of the most prevalent technologies, providing users a variety of benefits. However, SNS also provide user sufficient opportunities to access others’ positive information. This would elicit envy. In the current study, we develop a theoretical framework that elaborates the mechanism through which online envy is generated and influences SNS usage....

this study tries to review the reasons for which young girls tend to perform beauty surgeries on their faces, within the framework of veblen’s “theory of the leisure class” and his “social models” such as fiscal ownership. the statistical society has been the girl students of the university of tehran selected through snow ball sampling and discourse analysis was applied to analyze the semi-stru...

The novel as a modern literary genre is generally regarded as the realization of its main character's journey from immaturity to a status of maturity. The character, usually an uncomplicated person unable to cope with the complexities of life at first, gains an insight and understanding to handle his/her complex situation accordingly later in the novel. It is usually agreed in both literary cri...
