Abstract

The present paper studies resource allocation in an expanding product variety framework à la Romer (1990). We consider the limiting case where net returns to specialization are zero and, therefore, R&D is completely useless, socially. Nevertheless, the market equilibrium involves allocation of ressources to R&D, and this wasteful allocation may take place even in a steady state.
