Social and Technological Efficiency of Patent Systems

  • Thomas VALLEE (LEN-C3E)
  • Murat YILDIZOGLU (E3i, IFReDE-GRES)

This article develops an evolutionary model of industry dynamics in order to carry out a richer theoretical analysis of the consequences of a stronger patent system. The first results obtained in our article are rather consistent with the anti-patent arguments and they do not favour the case for a stronger patent system: higher social welfare and technical progress are observed in our model in industries with milder patent systems (lower patent height and patent life).
