Cross-Efficiency Evaluation Method with Compete-Cooperate Matrix

Correlated Cascades: Compete or Cooperate

In real world social networks, there are multiple diffusion processes which are rarely independent. They usually interact with each other in a competitive or cooperative manner. In this paper, motivated by the reinforcement theory in sociology, we model the adoption behavior of users in social networks by a multivariate marked Hawkes process. According to this model, the intensity of a user to ...

Rac and Rho compete to cooperate

Should You Compete or Cooperate with Your Schoolmates?

Should You Compete or Cooperate with Your Schoolmates? Building upon some education studies finding that cooperative behaviour in class yields better achievements among students, this paper presents a simple model showing that free riding incentives lead to an insufficient degree of cooperation between schoolmates, which in turn decreases the overall achievement. A cooperative learning approach...

Do grandparents compete with or support their grandchildren? In Guatemala, paternal grandmothers may compete, and maternal grandmothers may cooperate

Previous research has found that the presence of grandparents, particularly grandmothers, is often positively associated with child survival. Little research has explored the potential mechanisms driving these associations. We use data from rural Guatemala to test whether contact with and direct investment (advice and financial) from grandparents is associated with child health, proxied by heig...
