Evolutionary modelling in the Nelson-Winter tradition
	Because of its pioneering status and its relative simplicity, the model of Schumpeterian competition presented in Nelson and Winter's An Evolutionary Theory of Economic Change (1982, Chs 12-14) has obtained a prominent role in defining what evolutionary economics is about. From this model we know that economic evolution can be depicted as a process in which firms follow rules or routines that can occasionally be mutated or adapted. We also know that an important example of economic evolution takes place within an industry where new process techniques are introduced and imitated. These and other aspects of the Nelson-Winter model have to some extent defined a "paradigm" for further research on the conditions of R&D as a determinant of industrial concentration, dynamic competition in alternative technological regimes, the relationship between innovators and imitators, etc. A variant of the Nelson-Winter model (1982, Ch. 9) has also had some influence in promoting evolutionary growth theory. Therefore, it is relavant to study both the basic NelWin model and some of its many extensions.
