Investment decision-making is modeled by means of a Kohonen neural net, whose neurons represent firms as decision-makers. Thus, the network reconstructs collective decision-making by the productive system. This model focuses on the decision to invest in novel fields of activity, which requires...

The paper presents a dynamic model of endogenous growth with boundedly-rational, locally interacting, firms. Technologies are randomly distributed in a n-dimensional lattice (the productivity space) in such a way that distances between any two practices in the lattice can be taken as a proxy of...
