some specific effects (of network) initiates processes of positive feedback, meaning that any initial difference in the …

This paper investigates how employment intermediaries affected the inter-firm network of worker mobility in an region … transfers of workers between firms. Using network-based methodologies we find that temporary employment agencies significantly … increase network integration and practicability, while fastly increasing control over hiring channels. The policy implications …

crucially depend on the details of the communication network among agents. The main contribution of this paper is to show that …

We investigate the impact of network structures describing reciprocal influence-relationships between agents on their … uncertainty. The model could explain specific network dynamics observed in markets with asymmetric or not perfect information on …

This paper studies the impact of a probabilistic risk-sharing network structure on the optimal portfolio composition … function of his location in the network. If we assume positive asset-correlation coefficients, the relative location of a …-straightforward way. We analyse also two potential "centrality measures" able to select the key-player in the risk-sharing network. The …

how the speed of learning by chit-chat depends on the structure of the environment. A network represents the environment … meetings depends on the underlying network structure and we use this quantity to investigate the speed of learning in the … distribution (MPS). Specifically, if the number of individuals is low (high), then a MPS of the network increases (decreases) the …

Network is often considered as a support of knowledge creation. We consider that two main forms of networks can be … creation. The aim of this article is then to demonstrate mathematically the hypothesis that a decentralized network is more … forms of network in order to compare afterwards their dynamical evolution.
