L.S. Penrose was the first to propose a measure of voting power (which later came to be known as 'the (absolute) Banzhaf (Bz) index'). His limit theorem - which is implicit in his booklet (1952) and for which he gave no rigorous proof - says that in simple weighted voting games (WVGs), if the...

We consider a game played by a state sponsor of terrorism, a terrorist group, and the target of terrorist attacks.

This paper proposes a new measure for a group's ability to lead society to adopt their standard of behavior, which in particular takes account of the time the group takes to convince the whole society to adopt their position. This notion of a group's power to initiate action is computed as the...

We study the impact of bots on social learning in a social network setting. Regular agents receive independent noisy signals about the true value of a variable and then communicate in a network. They na¨ıvely update beliefs by repeatedly taking weighted averages of neighbors' opinions. Bots...

The novelty of our model is to combine models of collective action on networks with models of social learning. Agents are connected according to an undirected graph, the social network, and have the choice between two actions: either to adopt a new behavior or technology or stay with the default...

In this paper I consider how individuals allocate their time between church attendance (and other religious activities) and secular leisure activities. Moreover individuals use a cognitive style, which is either intuitive-believing or reflective-analytical. I assume that the full benefit from...
