What this is

The realized assignment of a procurement cartel, reconstructed from a public antitrust ruling. Indecopi’s Resolución 080-2021/CLC (15 November 2021) sanctioned thirty-two construction groups for rigging Ministry of Transport road tenders between November 2002 and December 2016. This dataset is the tender-and-firm universe behind the paper The Price of Corruption.

Most of the collusion-detection literature has to infer which tenders were rigged from bid distributions. Here the competition authority adjudicated each tender, so the colluded/competitive label is observed, which makes the data useful for validating screens, studying cartel governance, and measuring overcharge.

All tables are firm-level and built entirely from the public resolution. No personal data is included.

Contents
  • 78 reconstructed road tenders with project, year, winning consortium and members, reference and offered values.
  • Firm × process roles (winning member, cover bidder, uncertain-target cover, participant without support).
  • 32 sanctioned economic groups with RUC, conduct dates, fines (UIT), and remedies.
  • Offer-level bids (Anexo 2) with the colluded/competitive classification.
  • Illicit benefit and reference values (Anexo 3) in the QA’d Excel transcription.
  • Exposure measures (firm- and process-level) and a SEACE/OCDS validation crosswalk.
  • A README.md and DATA_DICTIONARY.md.
