Natural Oligopoly in Intermediated Markets

Author

  • Thomas Gehrig

Abstract

) and convergence to a fragmented industrial structure does not obtain as the economy grows large. In particular, we find a natural oligopoly in which in general there are three larger intermediaries of similar size and one smaller intermediary occupying niche markets. Nevertheless, as the number of islands increases, spreads shrink to zero and almost competitive allocations arise.
