The first interests with regards to policy diffusion were focused in time variation or state lottery adoption,[REF] but more recently interest has shifted towards mechanisms (emulation, learning and coercion)[REF][REF] or in channels of diffusion[REF] where researchers find that regulatory agency creation is transmitted by country and sector channels.
Eveland evaluated diffusion from a phenomenological view, stating, "Technology is information, and exists only to the degree that people can put it into practice and use it to achieve values" [REF].
