Table 2.

Model variables.

Fixed factors in the model: • TotalPopulation • AdoptionFraction • ContactRate • ImitationEffectiveness

Variables in the model: • PotentialAdopters (initial value) = TotalPopulation • AdoptionFromImitation = PotentialAdopters * ImitationEffectiveness • AdoptionFromWOM = Adopters * PotentialAdopters * ContactRate * AdoptionFraction/TotalPopulation • AdoptionRate = AdoptionFromImitation + AdoptionFromWOM • d(PotentialAdopters)/dt = –AdoptionRate

Variables in the system dynamics model for behavior dynamics.
