Supplier sanction risk in Peruvian public procurement: supplier-year panel dataset with reconstructed sanction history, 2018–2025

Consortium awards are split equally among members, because participation shares are not published.</p><p dir="ltr">Sanction history reconstruction: the current public sanctions registry removes sanctions that expired more than four years earlier, which would substantially undercount past sanctions (for example, 420 instead of 1,681 debarments starting in 2019). The full history was reconstructed by merging 36 archived versions of the debarment file and 31 of the fines file published by the regulator, yielding 16,635 debarments and 6,564 fines.</p><p dir="ltr">Files: the ZIP contains one Excel workbook with five sheets: Panel_proveedor_anio (data, 53 variables), Sanciones_OECE (reconstructed sanction registry), Diccionario (variable definitions, role and time of availability), Resumen_por_anio (annual counts and sanction rates) and Fuentes (source URLs).</p><p dir="ltr">Notes: labels for t = 2025 cover sanctions starting up to 26 September 2026 only (flag VENTANA_ETIQUETA_COMPLETA = 0).

Supplier names are omitted from the panel sheet; the RUC is the identifier.</p><p dir="ltr">Source: Peru's Public Procurement Agency (OECE, formerly OSCE) open data: CONOSCE award and consortium files 2018–2025, sanctioned suppliers registries (debarments and fines) and contractual penalties.
