We have taken a model showing the interactions between the demand for a product and the ability to produce that product and extended it to deal with more than one producer. In addition to providing good technical background on the use of Subscripts, the model has provided some useful insights into the nature of new product markets. Policies that, in a monopoly situation, smooth out the transition can, in the face of a competitive supplier, simply benefit the competitor. It is true, in general, that as more detail is put in about the parties involved in a process it is possible to identify some as benefiting more strongly than others as new policies are implemented.
