Industry profits and free entry in input markets

Author

Listed:
  • Matsushima, Noriaki

Abstract

When upstream firms compete in quantity and freely enter the input market, competition among downstream firms reduces the input price (the marginal cost of downstream firms). The industry profits of downstream firms competing in quantity can increase with the number of downstream firms.
