One of the most famous ranking methods for digraphs is the ranking by Copeland score. The Copeland score of a node in a digraph is the difference between its outdegree (i.e. its number of outgoing arcs) and its indegree (i.e. its number of ingoing arcs). In the ranking by Copeland score, a node...

(3) Initial inclinations determine the critical mass of … network and other parameters. Given the complexity of the system we use a standard technique for estimating the solution …

Agents involved in the formation of a social or economic network typically face uncertainty about the benefits of … creating a link. However, the interplay of such uncertainty and risk attitudes has been neglected in the network formation … literature. We propose a dynamic network formation model that builds on standard microeconomic concepts of utility maximization …

In this paper, we connect the social network theory on centrality measures to the economic theory of preferences and … different networks. The famous degree measure assigns to every position in a weighted network the sum of the weights of all … links with its neighbours. A crucial property of a preference relation over network positions is neutrality to ordinary risk …

This paper aims to connect the social network literature on centrality measures with the economic literature on von … Neumann-Morgenstern expected utility functions using cooperative game theory. The social network literature studies various … concepts of network centrality, such as degree, betweenness, connectedness, and so on. This resulted in a great number of …

Health shocks are among the most important unprotected risks for microfinance clients, but the take-up of micro health insurance typically remains limited. This pa- per attributes low enrollment rates to a social dilemma. Our theory is that in jointly liable groups, insurance is a public good....

We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The bene??it of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system without...

Many economic organizations have some relational structure, meaning that economic agents do not only differ with respect to certain individual characteristics such as wealth and preferences, but also belong to some relational structure in which they usually take different positions. Two examples...
