In particular, imitation is subject to a money pump if and … condition for imitation not being subject to a money pump is that the relative payoff game is a generalized ordinal potential …

We introduce a generalized theoretical approach to study imitation and subject it to rigorous experimental testing. In … our theoretical analysis we find that the different predictions of previous imitation models are due to different … effects of seemingly innocent changes in information. Moreover, the generalized imitation model predicts the differences …
