Local and Consistent Centrality Measures in Networks
Dequiedt, Vianney; Zenou, Yves - C.E.P.R. Discussion Papers - 2014
The centrality of an agent in a network has been shown to be crucial in explaining different behaviors and outcomes. In this paper, we propose an axiomatic approach to characterize a class of centrality measures for which the centrality of an agent is recursively related to the centralities of...

Gossip: Identifying Central Individuals in a Social Network
Banerjee, Abhijit; Chandrasekhar, Arun G; Duflo, Esther; … - C.E.P.R. Discussion Papers - 2014
Can we identify the members of a community who are best- placed to diffuse information simply by asking a random sample of in- dividuals? We show that boundedly-rational individuals can, simply by tracking sources of gossip, identify those who are most central in a network according to...

Trading and information diffusion in OTC markets
Babus, Ana; Kondor, Péter - C.E.P.R. Discussion Papers - 2013
We model trading and information diffusion in OTC markets, when dealers can engage in many bilateral transactions at the same time. We show that information diffusion is effective, but not efficient. While each bilateral price partially reveals all dealers' private information after a single...

The Missing Transfers: Estimating Mis-reporting in Dyadic Data
Comola, Margherita; Fafchamps, Marcel - C.E.P.R. Discussion Papers - 2015
Many studies have used self-reported dyadic data without exploiting the pattern of discordant answers. In this paper we propose a maximum likelihood estimator that deals with mis-reporting in a systematic way. We illustrate the methodology using dyadic data on inter-household transfers from the...

Bank Networks: Contagion, Systemic Risk and Prudential Policy
Aldasoro, Iñaki; Delli Gatti, Domenico; Faia, Ester - C.E.P.R. Discussion Papers - 2015
We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a...

Production Networks, Geography and Firm Performance
Bernard, Andrew B.; Moxnes, Andreas; Saito, Yukiko U. - C.E.P.R. Discussion Papers - 2015
This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

Simultaneous Search and Network Efficiency
Gautier, Pieter A; Holzner, Christian - C.E.P.R. Discussion Papers - 2011
When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects network clearing). We show that those frictions and the...

Asset Commonality, Debt Maturity and Systemic Risk
Allen, Franklin; Babus, Ana; Carletti, Elena - C.E.P.R. Discussion Papers - 2011
We develop a model in which asset commonality and short-term debt of banks interact to generate excessive systemic risk. Banks swap assets to diversify their individual risk. Two asset structures arise. In a clustered structure, groups of banks hold common asset portfolios and default together....
