We introduce a generalized theoretical approach to study imitation models and subject the models to rigorous … experimental testing. In our theoretical analysis we find that the different predictions of previous imitation models are due to … the generalized imitation model predicts the differences between treatments well. The data also provide support for …

endogenous technology innovation and imitation. We show that, unlike the neoclassical growth framework, the transitional dynamics …

technology that exhibits diminishing imitation opportunities is sufficient to account for the observed average patterns. We also …
