A physician performs two tasks: making diagnoses and determining treatments. To reduce medical error, residents are supposed to consult their supervisors when they face uncommon circumstances. However, recent research shows that residents are reluctant to do so. This paper presents a model that...

We study cooperative games with communication structure, represented by an undirected graph. Players in the game are … complete communication structure, then the proposed solution coincides with the Shapley value, and that if the game has a cycle …-free communication structure, it is the solution proposed by Herings, van der Laan and Talman (2008). We introduce the notion of link …

In this paper we introduce an extension of the model of restricted communication in cooperative games as introduced in … Myerson (1977) by allowing communication links to be directed and the worth of a coalition to depend on the order in which the … players enter the coalition. Therefore, we model the communication network by a directed graph and the cooperative game by a …

In this paper we test the celebrated quot;Strength of weak tiesquot; theory of Granovetter (1973). We test two hypotheses on the network structure in a data set of collaborating economists. While we find support for the hypothesis of transitivity of strong ties, we reject the hypothesis that...

This paper proposes a simple social network model of occupational segregation, generated by the existence of inbreeding bias among individuals of the same social group. If network referrals are important in getting a job, then expected inbreeding bias in the social structure results in different...

Can online social contacts replace the importance of real-life social connections in our pursuit of happiness? With the growing use of social network sites (SNSs), attention has been increasingly drawn to this topic. Our study empirically examines the effect of SNS use on happiness for different...

Hypercongestion - the phenomenon that higher traffic densities can reduce throughput - is well understood at the link level, but has also been observed in a macroscopic form at the level of traffic networks; for instance, in morning rush-hour traffic into a downtown core. In this paper, we show...
