We interview both parents and their children enrolled in six primary schools in the district of Treviso (Italy). We study the structural differences between the children network of friends reported by children and the one elicited asking their parents. We find that the parents' network has a...

The conditions under which young workers find their first real post-graduation jobs are both very important for the young's future careers and insufficiently known given their public policy implications. To study these conditions, and in particular the role played by networks, we use a Swedish...

A random intersection graph is constructed by independently assigning each vertex a subset of a given set and drawing an edge between two vertices if and only if their respective subsets intersect. In this paper a model is developed in which each vertex is given a random weight, and vertices...

The citation network of the International Journal of Research in Marketing (IJRM) is examined from 1981 to 1995. We propose a model that contains log-linear and logmultiplicative terms to estimate simultaneously the importance, cohesion, and structural equivalence of journals in the network...

Recently a variety of link-based stability concepts have emerged in the literature on game theoretic models of social network formation.We investigate two basic formation properties that establish equivalence between some well known types of stable networks and their natural extensions.These...

Gordon Tullock has been one of the most important founders and contributors to Public Choice. Two innovations are typical Tullock Challenges. The first relates to method: the measurement of subjective well-being, or happiness. The second relates to digital social networks such as Facebook,...

We evaluate a natural experiment at a Swedish university, in which students were randomized to either taking all their courses online, or to have some courses online and some on campus (blended learning). Our setting creates two groups for the online courses: One group with no access to campus...

We analyzed the impact of social networks on general practitioners' (GPs) referral behavior based on administrative panel data from 2,684,273 referrals to resident specialists made between 1998 and 2007. To construct estimated social networks, we used information on the doctors' place and time...
