The price of anarchy for network formation in an adversary model
Kliemann, Lasse - In: Games 2 (2011) 3, pp. 302-332
We study network formation with n players and link cost α 0. After the network is built, an adversary randomly deletes one link according to a certain probability distribution. Cost for player ν incorporates the expected number of players to which ν will become disconnected. We focus on...

Vertical mergers, foreclosure and raising rivals' costs: Experimental evidence
Normann, Hans-Theo - 2010
The hypothesis that vertically integrated firms have an incentive to foreclose the input market because foreclosure raises its downstream rivals' costs is the subject of much controversy in the theoretical industrial organization literature. A powerful argument against this hypothesis is that,...

Truth-telling and Trust in Sender-receiver Games with Intervention
Gurdal, Mehmet Y.; Ozdogan, Ayca; Saglam, Ismail - 2011
Recent experimental studies find excessive truth-telling in strategic information transmission games with conflictive preferences. In this paper, we show that this phenomenon is more pronounced in sender-receiver games where a truthful regulator randomly intervenes. We also establish that...

Abbink, Klaus; Brandts, Jordi - 2003
Bertrand competition under decreasing returns involves a wide interval of pure strategy equilibrium prices. We first present results of experiments in which two, three and four identical firms repeatedly interact in this environment. Less collusion with more firms leads to lower average prices....

Truth-telling and trust in sender-receiver games with intervention
Gurdal, Mehmet Y.; Ozdogan, Ayca; Sağlam, İsmail - 2011
Recent experimental studies find excessive truth-telling in strategic information transmission games with conflictive preferences. In this paper, we show that this phenomenon is more pronounced in sender-receiver games where a truthful regulator randomly intervenes. We also establish that...

Directed generosity and network formation : network dimension matters
D'Exelle, Ben; Riedl, Arno - 2010
We explore network effects on generosity for different network dimensions. To this end we elicit multiple network dimensions (friendship, social support, economic exchange, etc.) in a rural village in the Southern hemisphere and measure generosity with a sequence of dictator games conducted in...

Excess capacity and pricing in Bertrand-Edgeworth markets : experimental evidence
Fonseca, Miguel A.; Normann, Hans-Theo - 2012
We conduct experiments testing the relationship between excess capacity and pricing in repeated Bertrand-Edgeworth duopolies and triopolies. We systematically vary the experimental markets between low excess capacity (suggesting monopoly) and no capacity constraints (suggesting perfect...
