Modes of Knowledge Accumulation, Entry Regimes and Patterns of Industrial Evolution.

This paper explores the interplay between entry, selection and innovative learning as determinants of industrial evolution. It proposes a model aimed at capturing some essential features of learning and competition as drivers of the dynamics. Using both analytical and numerical techniques, the paper disentangles possible generic properties which robustly hold for a wide range of parameterizations. In particular, the paper identifies different generic "evolutionary archetypes", defined by characteristic interactions between entry/exit regimes, learning and industrial structures.
