We investigate the role of manipulation in a model of opinion formation where agents have opinions about some common question of interest. Agents repeatedly communicate with their neighbors in the social network, can exert some effort to manipulate the trust of others, and update their opinions...

We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors' expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an...

We investigate the role of manipulation in a model of opinion formation. Agents repeatedly communicate with their neighbors in the social network, can exert effort to manipulate the trust of others, and update their opinions about some common issue by taking weighted averages of neighbors'...

This paper analyzes the impact of changes in the winning chances of candidates running for the 2007 French presidential election on abnormal stock returns of firms that could benefit from a candidate's victory. We use prices formed by transactions on a political prediction market to reveal the...

This paper applies the methodological tools typical of social network analysis (SNA) within an evolutionary framework, to investigate the knowledge-base (KB) dynamics of the biotechnology sector. Knowledge is here considered a collective good represented as a co-relational and a...

In recent literature a relevant problem has been the relationship between career/personal contactnetworks and different career paths. In addition the recent advances in social capital theory have shown the way in which networks impact on personal careers. In particular women’s careers appear...

Due to the strong polarisation of economic activities in space and rise in collaborative behaviour, increasing attention has recently been devoted to the relationship between geography and network formation. The studies conducted on this topic reveal a high variation in terms of methodologies....

This chapter aims at providing an original review of the main theoretical approaches to technological knowledge, both implicit and explicit, and of their empirical counterparts in the field of economics of innovation. While there are in the literature interesting contributions aiming at...
