VisszaAbstract:
I will discuss my work in the field of network theory and its applications to Economics and Social Sciences. I will show how several properties of empirical social networks and financial markets can be reproduced as emerging properties of relatively simple theoretical models. The main focus will be on socio-economic systems characterized by the presence of many heterogeneous agents, each endowed with a piece of information (an opinion, a belief or a preference), which can be shared with some of the other members of a population (in a distributed fashion). To obtain a global understanding of the problem studied, different aggregation techniques will be used.
