We use a unique data set provided by the Public Procurement Authority of Turkey that covers all government procurement auctions for the years 2004-12, 588,454 auctions. We conclude that PEP adoption had adverse effects. The number of firms submitting bids in procurement auctions is significantly lower after PEP adoption. The procurement costs are significantly higher after PEP. These results suggest that policy makers should eliminate barriers to e-procurement adoption to gather the intended results of PEP.eninfo:eu-repo/semantics/closedAccesscompetitione-procurementpublic procurement auctionsArticle7
