We study the impact of research collaborations in coauthorship networks on total research output. Through the links in the collaboration network researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them. We characterize the interior...

Community enforcement is an important device for sustaining efficiency in some repeated games of cooperation. We investigate cooperation when information about players' reputations spreads to their future partners through links in a social network that connects them. We find that information...

Analyzing the topological properties of the network of shareholding relationships among the Euro Area banks we evaluate the relevance of a bank in the ?nancial system respect to ownership and control of other banks. We ?nd that the degree distribution of the European banking network displays...

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...

This paper studies the phenomenon of early hiring in entry-level labor markets (e.g. the market for gastroenterology fellowships and the market for judicial clerks) in the presence of social networks. We offer a two-stage model in which workers in training institutions reveal information on...

Spendensammelnde Nonprofit-Organisationen (NPOs) verfügen verglichen mit gewinnorientierten Unternehmen ähnlicher Grösse über relativ hohe finanzielle Reserven in Form eines Finanzvermögens. Deren Höhe hängt von verschiedenen Faktoren ab, die im Rahmen der vorliegenden Studie untersucht...

We study a structural model of R&D alliance networks in which firms jointly form R&D collaborations to lower their production costs while competing on the product market. We derive the Nash equilibrium of this game, provide a welfare analysis and determine the optimal R&D subsidy program that...

In this paper we analyze R&D collaboration networks in industries where firms are competitors in the product market. Firms' benefits from collaborations arise by sharing knowledge about a cost-reducing technology. By forming collaborations, however, firms also change their own competitive...

The networks of nominal flows between industries in a Social Accounting Matrix (SAM) framework are studied. The flows of the SAM submatrices of production (or output of goods and services) and intermediate consumption, are identified, which are constructed from the supply and use tables of the...

This monograph compares the methodologies and progress of the different existing models of information and communication technology (ICT) use for broad-based development and economic growth in India. It will examine the role of complementary reforms in government administration and policies. The...
