Testing the TASP: An experimental investigation of learning in games with unstable equilibria
Cason, Timothy N.; Friedman, Daniel; Hopkins, Ed - 2009
We report experiments designed to test between Nash equilibria that are stable and unstable under learning. The 'TASP … equilibrium under fictitious play like learning processes. We use two 4 x 4 games each with a unique mixed Nash equilibrium; one … is stable and one is unstable under learning. Both games are versions of Rock-Paper-Scissors with the addition of a …

Fictitious play in `one-against-all' multi-player games
Sela, Aner - In: Economic Theory 14 (1999) 3, pp. 635-651
A compound game is an (n + 1) player game based on n two-person subgames. In each of these subgames player 0 plays against one of the other players. Player 0 is regulated, so that he must choose the same strategy in all n subgames. We show that every fictitious play process approaches the set of...

Learning, Matching and Aggregation
Hopkins, Ed - ESRC Centre for Economic Learning and Social Evolution …
Fictitious play and "gradient" learning are examined in the context of a large population where agents are repeatedly … randomly matched. We show that the aggregation of this learning behaviour can be qualitatively di®erent from learning at the …

Constrained interactions and social coordination
Staudigl, Mathias; Weidenholzer, Simon - In: Journal of Economic Theory 152 (2014) C, pp. 41-63
We consider a co-evolutionary model of social coordination and network formation where agents may decide on an action in a 2×2-coordination game and on whom to establish costly links to. We find that if agents may only support a limited number of links payoff dominant conventions will emerge in...

Fictitious play in networks
Ewerhart, Christian; Valkanova, Kremena - 2016
This paper studies fictitious play in networks of noncooperative two-player games. We show that continuous-time fictitious play converges to Nash equilibrium provided that the overall game is zero-sum. Moreover, the rate of convergence is 1/T , regardless of the size of the network. In contrast,...

Fictitious play in networks
Ewerhart, Christian; Valkanova, Kremena - 2019
This paper studies fictitious play in networks of noncooperative two-person games. We show that continuous-time fictitious play converges to the set of Nash equilibria if the overall n-person game is zero-sum. Moreover, the rate of convergence is 1/T, regardless of the size of the network. In...
