We present an agent-based model of innovation processes, based upon a theory of innovationby Lane and Maxfield. The theory inspires and constrains the features of the model,thus reducing the embarasse de richesse that is one of the major methodological problems ofagent-based modeling. Artefacts are produced by agents using recipes; the basic dynamics,absent innovation, is one of production and sales, where the external world supplies "rawmaterials" and external demand. Depending upon the initial conditions, self-sustainingcycles of production and exchange can emerge among the agents. Innovation – that is,the generation of new recipes, in particular desired directions, called "goals" – results insubstantial modification of the system dynamics. Two innovation regimes are introduced:a "lonely" mode, in which each agent tries to introduce new products by itself, and a"relational" mode, in which two agents can improve their reciprocal knowledge and candecide to try to jointly develop a new artifact.
