Superstar economists : coauthorship networks and research output
Zimmermann, Christian; Hsieh, Chih-sheng; König, Michael D. - 2018
We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....

This study examines the impact of a behavioral intervention on reducing discrimination against Venezuelan migrants in the screening of home rental applications conducted by Ecuadorian real estate agents (REAs). Given that Venezuelan migrants represent the second-largest migratory group globally,...

Incorporating fairness motives into the impulse balance equilibrium and quantal response equilibrium concepts : an application to 2x2 games
Tavoni, Alessandro - 2009
Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts...

Learning to play approximate Nash equilibria in games with many players
Cartwright, Edward - 2004
We illustrate one way in which a population of boundedly rational individuals can learn to play an approximate Nash equilibrium. Players are assumed to make strategy choices using a combination of imitation and innovation. We begin by looking at an imitation dynamic and provide conditions under...

Whom can you trust? : reputation and cooperation in networks
King, Maia - 2017
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...

How homophily affects learning and diffusion in networks
Golub, Benjamin; Jackson, Matthew O. - 2009
We examine how three different communication processes operating through social networks are affected by homophily - the tendency of individuals to associate with others similar to themselves. Homophily has no effect if messages are broadcast or sent via shortest paths; only connection density...

Under-connected and over-connected networks
Hellmann, Tim; Buechel, Berno - 2009
Since the seminal contribution of Jackson & Wolinsky 1996 [A Strategic Model of Social and Economic Networks, JET 71, 44-74] it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has...

Opinion dynamics and wisdom under conformity
Buechel, Berno; Hellmann, Tim; Kölßner, Stefan - 2014
We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors' expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an...
