Unknown effects of social innovations

The Spread of Innovations by Social Learning

The spread of innovations in social networks.

Which network structures favor the rapid spread of new ideas, behaviors, or technologies? This question has been studied extensively using epidemic models. Here we consider a complementary point of view and consider scenarios where the individuals' behavior is the result of a strategic choice among competing alternatives. In particular, we study models that are based on the dynamics of coordina...

The Diffusion of Innovations in Social Networks

We consider processes in which new technologies and forms of behavior are transmitted through social or geographic networks. Agents adopt behaviors based on a combination of their inherent payoff and their local popularity (the number of neighbors who have adopted them) subject to some random error. We characterize the long-run dynamics of such processes in terms of the geometry of the network,...

The Diffusion of Innovations in Social Networks

This paper determines how different network structures influence the diffusion of innovations. We develop a model of diffusion where: 1. an individual’s decision to adopt a new technology is influenced by his contacts; and 2. contacts can discuss, coordinate, and make adoption decisions together. A measure of connectedness, ‘cohesion’, determines diffusion. A cohesive community is defined as a ...

Social Cognitive Theory in Mobile Banking Innovations

This paper examines the behavior Australian youths have toward mobile banking. Social cognitive theory is the theoretical framework in which a conceptual model is empirically tested. The conceptual model includes five constructs (media, modeling, outcome expectancy, learning orientation and entrepreneurial orientation), which are proposed to influence an individual’s intention to adopt mobile b...
