Evidence is growing that forms of incivility –e.g. aggressive and disrespectful behaviors, harassment, hate speech and outrageous claims– are spreading in the population of social networking sites’ (SNS) users. Online social networks such as Facebook allow users to regularly interact with...

Abstract Social media have been credited with the potential of reinvigorating trust by offering new opportunities for social and political participation. This view has been recently challenged by the rising phenomenon of online incivility, which has made the environment of social networking...

This paper addresses two hot topics of the contemporary debate, social capital and economic growth. Our theoretical analysis sheds light on decisive but so far neglected issues: how does social capital accumulate over time? Which is the relationship between social capital, technical progress and...

We develop a dynamic model to analyze the sources and the evolution of social participation and social capital in a growing economy characterized by exogenous technical progress. Starting from the assumption that the well-being of agents basically depends on material and relational goods, we...

We develop a dynamic model to analyze the sources and the evolution of social participation and social capital in a growing economy characterized by exogenous technical progress. Starting from the assumption that the well-being of agents basically depends on material and relational goods, we...

This paper proposes an evolutionary framework to explore the dynamics of social interaction in an environment characterized by online networking and increasing pressure on time. The model shows how time pressure encourages the choice to develop social interactions also through online networking...

Empirical studies have documented a decline in indicators of social participation in the last decades. The responsibility of social disengagement has been often attributed to pervasive busyness and the rising pressure of time. In this paper we argue that computer-mediated interaction, and...

We set up a theoretical framework to analyze the possible role of economic growth and technical progress in the erosion of social capital. Under certain parameters, the relationship between technical progress and social capital can take the shape of an inverted U curve. We show the circumstances...

The objective of this paper is to theoretically analyze how human interaction may evolve in a world characterized by the explosion of online networking and other Web-mediated ways of building and nurturing relationships. The analysis shows that online networking yields a storage mechanism...

We have developed an evolutionary game model, where agents can choose between two forms of social participation: interaction via online social networks and interaction by exclusive means of face-to-face encounters. We illustrate the societal dynamics that the model predicts, in light of the...
