Title:Risk-sharing and contagion in networks
Author(s):CABRALES, Antonio; GOTTARDI, Piero; VEGA-REDONDO, FernandoDate:2013Type of Publication:Working PaperSeries/Report no.:EUI ECOAbstract:The aim of this paper is to investigate how the capacity of an economic system to absorb shocks depends on the specific pattern of interconnections established among financial firms. The key trade-off at work is between ...
Title:Social Networks and the Process of “Globalization”
Author(s):DUERNECKER, Georg; VEGA-REDONDO, FernandoDate:2012Type of Publication:Working PaperSeries/Report no.:EUI ECOAbstract:We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call “globalization.” This term refers to the process by which even agents who are geographically far apart come to interact, ...
Title:Being Close to Grow Faster: A network-based empirical analysis of economic globalization
Author(s):DUERNECKER, Georg; MEYER, Moritz; VEGA-REDONDO, FernandoDate:2012Type of Publication:Working PaperSeries/Report no.:EUI ECOAbstract:Globalization features one of the major global trends which shape economic outcomes in developing and developed countries. Standard results from the empirical growth literature suggest that participation in worldwide trade ...
Title:Threshold Learning Dynamics in Social Networks
Author(s):GONZÁLEZ-AVELLA, Juan Carlos; EGUÍLUZ, Victor M.; MARSILI, Matteo; VEGA-REDONDO, Fernando; SAN MIGUEL, MaxiDate:2011Type of Publication:ArticleAbstract:Social learning is defined as the ability of a population to aggregate information, a process which must crucially depend on the mechanisms of social interaction. Consumers choosing which product to buy, or voters deciding ...
Title:Error Cascades in Observational Learning: An experiment on the Chinos game
Author(s):FERI, Francesco; MELÉNDEZ-JIMÉNEZ, Miguel A.; PONTI, Giovanni; VEGA-REDONDO, FernandoDate:2011Type of Publication:ArticleAbstract:The paper reports an experimental study based on a variant of the popular Chinos game, which is used as a simple but paradigmatic instance of observational learning. There are three players, arranged in sequence, each of ...
Title:Complex Networks and Local Externalities: A strategic approach
Author(s):VEGA-REDONDO, Fernando; GALEOTTI, AndreaDate:2011Type of Publication:ArticleAbstract:In this paper, we illustrate a new approach to the study of how local externalities shape agents’ strategic behavior when the underlying network is volatile and complex. We consider a large population that interacts as ...
Title:Vertex Centralities in Input-Output Networks Reveal the Structure of Modern Economies
Author(s):BLÖCHL, Florian; THEIS, Fabian J.; VEGA-REDONDO, Fernando; FISHER, Eric O’N.Date:2011Type of Publication:ArticleAbstract:Input-output tables describe the flows of goods and services between the sectors of an economy. These tables can be interpreted as weighted directed networks. At the usual level of aggregation, they contain nodes with ...
Title:Optimal Information Transmission in Organizations: Search and Congestion
Author(s):ARENAS, Alex; CABRALES, Antonio; DANON, Leon; DIAZ-GUILERA, Albert; GUIMERA, Roger; VEGA-REDONDO, FernandoDate:2010Type of Publication:ArticleAbstract:We propose a stylized model of a problem-solving organization whose internal communication structure is given by a fixed network. Problems arrive randomly anywhere in this network and must find their way to their respective ...
Title:The Option to Leave: Conditional Dissociation in the Evolution of Cooperation
Author(s):IZQUIERDO, Segismundo S.; IZQUIERDO, Luis R.; VEGA-REDONDO, FernandoDate:2010Type of Publication:ArticleAbstract:Conditional dissociation, i.e. the option to leave an interacting partner in response to his behaviour, is a mechanism that has been shown to promote cooperation in several settings, but the fundamental features that make ...
Title:Peer Effects and Peer Avoidance: The Diffusion of Behavior in Coevolving Networks
Author(s):FOSCO, Constanza; MARSILI, Matteo; VEGA-REDONDO, FernandoDate:2010Type of Publication:ArticleAbstract:We study the long-run emergence of behavioral patterns in dynamic complex networks. Individuals can display two kinds of behavior: G(good) or B (bad). We assume that the exposure of a G agent to bad behavior on the part ...
Title:Network Games
Author(s):GALEOTTI, Andrea; GOYAL, Sanjeev; JACKSON, Matthew O.; VEGA-REDONDO, Fernando; YARIV, LeeatDate:2010Type of Publication:ArticleAbstract:In contexts ranging from public goods provision to information collection, a player's well-being depends on his or her own action as well as on the actions taken by his or her neighbours. We provide a framework to analyse ...
Title:Economic Networks: What Do We Know and What Do We Need to Know?
Author(s):SCHWEITZER, Frank; FAGIOLO, Giorgio; SORNETTE, Didier; VEGA-REDONDO, Fernando; WHITE, Douglas R.Date:2009Type of Publication:ArticleAbstract:We examine the emergent field of economic networks and explore its ability to shed light on the global and volatile economy where credit, ownership, innovation, investment, and virtually every other economic activity is ...
Title:Peer Effects and Peer Avoidance: Epidemic Diffusion in Coevolving Networks
Author(s):FOSCO, Constanza; MARSILI, Matteo; VEGA-REDONDO, FernandoDate:2008Type of Publication:Working PaperSeries/Report no.:EUI ECOAbstract:We study the long-run-emergency of behavioral patterns in dynamic complex networks. Individuals display two kinds of behavior: G("good") or B ("bad"). We assume that agents have an innate tendency towards G, but can also ...

Title:Network Organizations
Author(s):VEGA-REDONDO, FernandoDate:2008Type of Publication:Working PaperSeries/Report no.:EUI ECOAbstract:It is common to define a network organization as one that is fast and flexible in adapting to changes in the underlying environment. But besides the short-run advantages of adaptability, fast changes in the structure of ...
Title:Networks Emerging in a Volatile World
Author(s):EHRHARDT, Gorge; MARSILI, Matteo; VEGA-REDONDO, FernandoDate:2008Type of Publication:Working PaperSeries/Report no.:EUI ECOAbstract:The paper proposes a model to study the conditions under which complex networks emerge (or not) when agents are involved in a dynamic coordination setup. The focus, however, is not on the classical issue of equilibrium ...
Title:Structural holes in social networks
Author(s):GOYAL, Sanjeev; VEGA-REDONDO, FernandoDate:2007Type of Publication:ArticleAbstract:We consider a setting where every pair of players that undertake a transaction (e.g. exchange goods or information) creates a unit surplus. A transaction can take place only if the players involved have a connection. If ...
