Structure and strategy in collective action
TLDR
In this article, the authors consider both structural and strategic influences on collective action and show that strong and weak links are better for revolt when thresholds are low, and strong links were better when thresholds were high.Abstract:
This article considers both structural and strategic influences on collective action. Each person in a group wants to participate only if the total number taking part is at least her threshold; people use a network to communicate their thresholds. People are strategically rational in that they are completely rational and also take into account that others are completely rational. The model shows first that network position is much more important in influencing the revolt of people with low thresholds than people with high thresholds. Second, it shows that strong links are better for revolt when thresholds are low, and weak links are better when thresholds are high. Finally, the model generalizes the threshold models of Schelling (1978) and Granovetter (1978) and shows that their findings that revolt is very sensitive to the thresholds of people “early” in the process depends heavily on the assumption that communication is never reciprocal.read more

Maximizing the spread of influence through a social network
TL;DR: An analysis framework based on submodular functions shows that a natural greedy strategy obtains a solution that is provably within 63% of optimal for several classes of models, and suggests a general approach for reasoning about the performance guarantees of algorithms for these types of influence problems in social networks.

Complex Contagions and the Weakness of Long Ties
Damon Centola,Michael W. Macy +1 more
TL;DR: The strength of weak ties is that they tend to be long and connect socially distant locations, allowing information to diffuse rapidly as discussed by the authors, which may explain the widely observed tendency for social movements to diffuse spatially.

A Noncooperative Model of Network Formation
Venkatesh Bala,Sanjeev Goyal +1 more
TL;DR: An approach to network formation based on the notion that social networks are formed by individual decisions that trade off the costs of forming and maintaining links against the potential rewards from doing so to formulate the network formation process as a noncooperative game.

FROM FACTORS TO ACTORS: Computational Sociology and Agent-Based Modeling
Michael W. Macy,Robert Willer +1 more
TL;DR: Agent-based models (ABMs) as mentioned in this paper have been widely used in computational sociology to model social life as interactions among adaptive agents who influence one another in response to the influence they receive, such as diffusion of information, emergence of norms, coordination of conventions or participation in collective action.

TL;DR: In this article, the conceptual and empirical foundations of community-based and driven development (CBD) initiatives are reviewed, and the authors find that projects that rely on community participation have not been particularly effective at targeting the poor.

The Strength of Weak Ties
TL;DR: In this paper, it is argued that the degree of overlap of two individuals' friendship networks varies directly with the strength of their tie to one another, and the impact of this principle on diffusion of influence and information, mobility opportunity, and community organization is explored.

Micromotives and Macrobehavior
TL;DR: The Micromotives and Macrobehavior was originally published over twenty-five years ago, yet the stories it tells feel just as fresh today as discussed by the authors, and the subject of these stories-how small and seemingly meaningless decisions and actions by individuals often lead to significant unintended consequences for a large group-is more important than ever.
