When banks extend loans to each other, they generate a negative externality in the form of systemic risk. They create a network of interbank exposures by which they expose other banks to potential insolvency cascades. In this paper, we show how a regulator can use information about the financial...

We consider a connection networks model. Every agent has a demand in the form of pairs of locations she wants connected, and a willingness to pay for connectivity. A planner aims at implementing a welfare maximizing network and allocating the resulting cost, but information is asymmetric: agents...

This paper examines network formation among a connected population with a preference for conformity and leadership. Agents build stable personal relationships to achieve coordinated actions. The network serves as a repository of collective experiences so that cooperation can emerge from simple,...

In this paper we address the manifold nature of knowledge through the analysis of four distinct but complementary phenomena (Internet hyperlinks, European research networks, EPO co-patent applications, Erasmus students mobility) that characterize knowledge as an intrinsic relational structure...

We provide an analysis of corporate governance networks implied by members of board of directors of 319 companies listed in Istanbul Stock Exchange (ISE) for the year 2007. Our configuration yields a bipartite network for which we provide small world statistics in addition to the usual measures...

Der Beitrag untersucht, inwieweit es durch eine Förderung mittels Technologieund Gründerzentren (TGZ) gelingt, Unternehmen beim Aufbau von Kooperationsbeziehungen zu unterstützen. Im Rahmen einer Querschnittsuntersuchung wird sowohl die Vernetzung der Unternehmen innerhalb der Zentren als...

We study a model of network formation and start-up financing with endogenous entrepreneurial type distribution. A hub firm admits members to its network based on signals about entrepreneurs' types. Network membership is observable, which allows lenders to offer different interest rates to...

This paper extends the theory of endogenous coalition formation, with complete information and transferable utility, to the overlapping case. We propose a cover function bargaining game which allows the formation of overlapping coalitions at equilibrium. We show the existence of subgame perfect...

In order to face the new competitive scenario, Apulian textile firms are involved in a process of change and are trying to adopt a networking approach in analysing the international propensity of SMEs. The case of the textile network in Apulia has been analysed using a semi-structured...

This paper provides evidence that interbank markets are tiered rather than flat, in the sense that most banks do not lend to each other directly but through money center banks acting as intermediaries. We capture the concept of tiering by developing a core-periphery model, and devise a procedure...
