SIdE Postgraduate Courses

June, 28 - July, 3, 2021, Venice, Italy

Summer School on Network Econometrics

Coordinator: Roberto Casarin (University Ca' Foscari of Venice). E-mail: r.casarin@unive.it

Instructors: Monica Billio (University Ca' Foscari of Venice), Roberto Casarin (University Ca' Foscari of Venice), Matteo Iacopini (Vrije University of Amsterdam), Sergio Petralia (Utrecht Univeristy and LSE), Luca Rossini (University of Milan).

The summer school is organized in collaboration with the Venice Center for Risk Analytics for Public Policies (VERA) and the Italian Society of Econometrics (SIdE).


The aim of the course is to provide students with models and tools from network and graph theory for the analysis of a wide variety of social, economic, financial and political interaction effects. The organization of the course can be split into three main part. The first is an introduction to some background in graph theory applied to social and economic networks. The second part deals with network models and the third with the practical issues of extracting latent networks and analysing networks in economics and finance. The main focus of the third part is on stochastic models for networks and temporal networks. The main focus of the practical examples will be on social, economics and financial networks. Partecipants will learn how to deal with network analysis in R, MATLAB and Gephi.
