The ideal of diffusion
The 1960s produced a series of economic commentaries on the way in which innovations spread throughout a market. Ranging from Rodgers in 19621 to Bass in 19692 these all developed around the concept of diffusion. Developed formally by Rodgers, and held by many people today, the diffusion theory is a specialised concept of communication. This communication, verbal, nonverbal, and observational, then produces a diffusion curve. What I will attempt to lay out here is a very short critique of the basic theory of diffusion. Unlike most economic commentaries however I will start before the innovation stage and use more recent studies into the sociology of science to examine the nature of scientific investigation and draw parallels to the nature of innovation. When diffusion models are examined in this way they are not only revealed as misleading descriptions of the interaction between firms and consumers, but lacking in any real explanatory power. I suggest instead that a translation model would be far more effective at both explaining the spread of innovations and offering advice towards more effective interactions between firms and markets in the future.
