Do new communication technologies, such as social media, reduce collective action problem? This paper provides evidence that penetration of VK, the dominant Russian online social network, affected protest activity during a wave of protests in Russia in 2011. As a source of exogenous variation in network penetration, we use information on the city of origin of the students who studied together with the founder of VK, controlling for the city of origin of the students who studied at the same university several years earlier or later. We find that a 10% increase in VK penetration increased the probability of a protest by 4.6%, and the number of protesters by 19%. Additional results suggest that social media has affected protest activity by reducing the costs of coordination, rather than by spreading information critical of the government. In particular, VK penetration increased pro-governmental support and reduced the number of people who were ready to participate in protests right before the protests took place. Also, cities with higher fractionalization of network users between VK and Facebook experienced fewer protests. Finally, we provide suggestive evidence that municipalities with higher VK penetration received smaller transfers from the central government after the occurrence of protests.

The Occupy movement and the Arab Spring have brought global attention to the potential of social media for empowering otherwise marginalized groups. This book addresses questions like what happens after the moment of protest and global visibility and whether social media can also help sustain civic engagement beyond protest.

Pinning down the role of social ties in the decision to protest has been notoriously elusive, largely due to data limitations. The era of social media and its global use by protesters offers an unprecedented opportunity to observe real-time social ties and online behavior, though often without an attendant measure of real-world behavior. We collect data on Twitter activity during the 2015 Charlie Hebdo protests in Paris which, unusually, record both real-world protest attendance and high-resolution network structure. We specify a theory of participation in which an individual's decision depends on her exposure to others' intentions, and network position determines exposure. Our findings are strong and consistent with this theory, showing that, relative to comparable Twitter users, protesters are significantly more connected to one another via direct, indirect, triadic, and reciprocated ties. These results offer the first large-scale empirical support for the claim that social network structure influences protest participation.

The book examines the highly dynamic communication ecology of recent contentious politics and its expanding digital footprint. First, it looks at the attainment of democratic citizenship through practice as street protests attract substantial numbers of followers who narrate their involvement or reflect on the claims and the implications of collective action on social media. Secondly, it considers the ramifications for contemporary democracy arising from the large-scale uptake of social media by variegated protest networks, which no longer pivot on the coordination capacity of bureaucratic movement organizations. The book ties these aspects together to propose that contentious politics can be a fertile ground for progressive civic participation.

This edited volume examines malaise with democracy within three middle-income Latin American countries - Chile, Argentina and Uruguay. In particular, the book focuses on the gap within public opinion on democratic system within the context of crisis of representation and breakdowns of democracy. Based on a study using comparative and systematic survey data, the contributors of this volume provide a solid analysis on the state of democracy in three Latin American countries, whose lessons are useful for all types of democracy, in the north and the south.

Digital and social media are increasingly integrated into the dynamics of protest movements around the world. They strengthen the mobilization power of movements, extend movement networks, facilitate new modes of protest participation, and give rise to new protest formations. Meanwhile, conventional media remains an important arena where protesters and their targets contest for public support. This book examines the role of the media -- understood as an integrated system comprised of both conventional media institutions and digital media platforms -- in the formation and dynamics of the Umbrella Movement in Hong Kong. For 79 days in 2014, Hong Kong became the focus of international attention due to a public demonstration for genuine democracy that would become known as the Umbrella Movement. During this time, twenty percent of the local population would join the demonstration, the most large-scale and sustained act of civil disobedience in Hong Kong's history -- and the largest public protest campaign in China since the 1989 student movement in Beijing. On the surface, this movement was not unlike other large-scale protest movements that have occurred around the world in recent years. However, it was distinct in how bottom-up processes evolved into a centrally organized, programmatic movement with concrete policy demands. In this book, Francis L. F. Lee and Joseph M. Chan connect the case of the Umbrella Movement to recent theorizations of new social movement formations. Here, Lee and Chan analyze how traditional mass media institutions and digital media combined with on-the-ground networks in such a way as to propel citizen participation and the evolution of the movement as a whole. As such, they argue that the Umbrella Movement is important in the way it sheds light on the rise of digital-media-enabled social movements, the relationship between digital media platforms and legacy media institutions, the power and limitations of such occupation protests and new "action logics," and the continual significance of old protest logics of resource mobilization and collective action frames. Through a combination of protester surveys, population surveys, analyses of news contents and social media activities, this book reconstructs a rich and nuanced account of the Umbrella Movement, providing insight into numerous issues about the media-movement nexus in the digital era.
