We introduce a generalized theoretical approach to study imitation models and subject themodels to rigorous … experimental testing. In our theoretical analysis we find that the differentpredictions of previous imitation models are due to …. In alaboratory experiment we test the different theories by systematically varying informationconditions. We find that …

A well-known result by Vega-Redondo implies that in symmetric Cournot oligopoly, imitation leads to the Walrasian … actions will be played some fraction of the time in the long run. We then conduct experiments to check this fragility. We …

A well-known result by Vega-Redondo (1997) implies that in symmetric Cournot oligopoly, imitation leads to the … identical actions will be played some fraction of the time in the long run. We then conduct experiments to check this fragility …

The paper presents the concept of an imitation equilibrium and explores it in the context of some simple oligopoly … be suitable for imitation for various reasons. Only one of the most successful of the remaining members of the reference … group is imitated. Imitation is the adoption of the imitated player's strategy. Imitation equilibrium does not only mean …

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 …

The econometrics hinges on a model built upon Experience Weighted Attraction learning, and the …

We analyze a symmetric n-firm Cournot oligopoly with a heterogeneous population of optimizers and imitators. Imitators …

When this … cost differential is positive (i.e., imitation is relatively cheaper vis a vis Cournot), most firms use this heuristic and …
