The projection dynamic and the geometry of population games
Ratul Lahkar,William H. Sandholm +1 more
TL;DR: The projection dynamic is an evolutionary dynamic for population games derived from a model of individual choice in which agents abandon their current strategies at rates inversely proportional to the strategies' current levels of use.
Journal ArticleDOI
The Projection Dynamic and the Replicator Dynamic
TL;DR: A variety of connections between the projection dynamic and the replicator dynamic are investigated, finding that the two dynamics exhibit qualitatively similar behavior in strictly stable and null stable games.
Journal ArticleDOI
The logit dynamic for games with continuous strategy sets
Ratul Lahkar,Frank Riedel +1 more
TL;DR: It is shown that in a restricted state space of probability measures with bounded density functions, solution trajectories of the logit dynamic converge to logit equilibria in potential games and negative semidefinite games.
Journal ArticleDOI
The dynamic instability of dispersed price equilibria
TL;DR: A finite strategy analogue of the Burdett and Judd (1983) price dispersion model is developed, showing that all dispersed price equilibria are unstable under the class of perturbed best response dynamics.
Journal ArticleDOI
Evolutionary implementation in a public goods game
Ratul Lahkar,Saptarshi Mukherjee +1 more
TL;DR: This work introduces the best response dynamic for such aggregative potential games to show evolutionary implementation of the efficient state in a large population public goods game and extends this result to other prominent evolutionary dynamics.
