The Evolution of R&D Networks
Dawid, Herbert - 2012
We study the evolution of R&D networks in a Cournot model where rms may lower marginal costs due to bilateral R&D collaborations. Stochastically stable R&D networks exhibit the dominant group architecture, and, contrary to the existing literature, generically unique predictions about the size of...

Evolutionary stability in asymmetric oligopoly : a non-Walrasian result
Leininger, Wolfgang; Moghadam, Hamed M. - 2014
It is a very well-known result that in terms of evolutionary stability the long-run outcome of a Cournot oligopoly …. Contrary to Tanaka (1999) we show that the evolutionarily stable price in an asymmetric Cournot oligopoly needs not equal the … order to transform the game with asymmetric firms into a symmetric oligopoly game and then extend Schaffer’s definition …

On the stability of CSS under the replicator dynamic
Louge, Fernando - 2010
This paper considers a two-player game with a one-dimensional continuous strategy. We study the asymptotic stability of equilibria under the replicator dynamic when the support of the initial population is an interval. We find that, under strategic complementarities, Continuously Stable Strategy...

On the dynamic foundation of evolutionary stability in continuous models
Oechssler, Joerg; Riedel, Frank - 2000
We show in this paper that none of the existing static evolutionary stability concepts (ESS, CSS, uninvadability, NIS) is sufficient to guarantee dynamic stability in the weak topology with respect to standard evolutionary dynamics if the strategy space is continuous. We propose a new concept,...

Imitation and the evolution of Walrasian behavior : theoretically fragile but behaviorally robust
Apesteguia, Joe; Huck, Steffen; Oechssler, Joerg; … - 2007
A well-known result by Vega-Redondo implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian …

R&D investments under endogenous cluster formation
Dawid, Herbert; Hellmann, Tim - 2016
We study investments in R&D and the formation of R&D clusters of firms which are competitors in the market. In a three stage game, firms first decide on long-term R&D investment, then form research clusters according to the unanimity game introduced in Bloch(1995), and finally compete in...
