Here we try to represent the diffusion of mitigation technologies across a population of farmers. The technology bring environmental benefits, but also costs to farmers. This is similar to the Bass model, I discovered today (20 Dec 2016). Another case of wheel re-invention
The cost ranges from negative (win:wins) to very high. We assume that adoption rate is influences by the cost.
In this simple model, cost can be interpreted here in a broad sense, as difficulty, which relates no only to monetary cost but also to things like current skill level of the farmer, for example.
A new loop is added to represent the likelihood of an adopted finding a potential adopter. This loop has very little effect on the evolution of Adopters. Why?
