Games on networks: Direct complements and indirect substitutes
Currarini, Sergio; Fumagalli, Elena; Panebianco, Fabrizio - 2013
Many types of economic and social activities involve significant behavioral complementarities (peer effects) with neighbors in the social network. The same activities often exert externalities that cumulate in stocks affecting agents' welfare and incentives. For instance, smoking is subject to...

Networks of commons
İlkiliç, Rahmi - 2008
A tragedy of the commons appears when the users of a common resource have incentives to exploit it more than the socially efficient level. We analyze the situation when the tragedy of the commons is embedded in a network of users and sources. Users play a game of extractions, where they decide...

Optimal equilibria of the best shot game
Pin, Paolo; Dall'Asta, Luca; Ramezanpour, Abolfazl - 2009
We consider any network environment in which the best shot game is played. This is the case where the possible actions are only two for every node (0 and 1), and the best response for a node is 1 if and only if all her neighbors play 0. A natural application of the model is one in which the...

Cournot competition on a network of markets and firms
Ilkiliç, Rahmi - 2009
Suppose markets and firms are connected in a bi-partite network, where firms can only supply to the markets they are connected to. Firms compete a la Cournot and decide how much to supply to each market they have a link with. We assume that markets have linear demand functions and firms have...
