Abstract
In this paper a model of technological evolution based on replicator dynamics is developed. Such a model is based on a twin characteristics representation of product technology and on a population approach. The model can give a general representation of technological evolution, but this paper concentrates on the relationship between variety and competition. Variety is considered to be a very important variable influencing economic development. By means of the characteristics and population approach adopted in this paper it is possible to distinguish between inter-and intra-technology competition. In this paper it is demonstrated that the variety of the system can only increase if intra-technology competition is more intense than inter-technology competition. Intuitively this implies that new technologies will only be able to emerge if incumbent technologies experience the competition coming from the new ones to be weaker than their own internal competition.
