A social welfare function for a denumerable society satisfies {Pairwise Computability} if for each pair (x,y) of alternatives, there exists an algorithm that can decide from any description of each profile on {x,y} whether the society prefers x to y. I prove that if a social welfare function...

In this paper, we examine an agent-based model and an equation-based model in the form of a mean field model. We show how the mean field model is a small, fast model that identifies the high level properties of a subject, in this case financial time series’ stylized facts. The agent based...

The dynamics of information dissemination in social networks is of paramount importance in processes such as rumors or fads propagation, spread of product innovations or "word-of-mouth" communications. Due to the difficulty in tracking a specific information when it is transmitted by people,...

A laboratory experiment studies coordination and cooperation in games played in different networks - local, random and small-world. Coordination on the payoff-dominant equilibrium was faster in small-world networks than in local and random networks. However, in a prisoner's dilemma game,...

This paper contains a model of waste elimination through design. It argues for the importance of managing design complexity in improving cost, quality, variety, and time-to-market performance variables. Management of design complexity is identified with creation, choice, and application of...

Discrimination is a pervasive aspect of modern society and human relations. Statistical discrimination theory suggests that profit-maximizing employers should use all the information about job candidates, including information about group membership (e.g., race or gender), to make accurate...

This paper illustrates an artificial ecosystem where hierarchical organizations emerge out of collisions between individuals, problems, solutions and choice opportunities according to the rules of the Garbage Can Model of organizational choice (GCM). This artificial world suggests that specific...
