In a nutshell

  • Public procurement comprises a significant part of GDP in both developing and developed countries.
  • I provide fundamental conditions for cost-effective public procurement using empirical findings from Turkish public procurement.
  • The presence of a competitive environment (i.e. the number of bidders in auctions) is the major determinant of public procurement efficiency
  • There is an optimal level of competition in public procurement:
  • Procurement costs are higher when the number of bidders is below the optimal level.
  • Too much competition might have unintended effects and increase procurement price.
  • Optimal level of competition changes with respect to procurement type (service, goods, and construction).
  • Depending on the type of procurement, the lowest possible procurement prices are achieved when there are five to 10 bidders.
  • Entrant firms decrease procurement costs, but are less likely to survive in the public procurement market compared to incumbents.
