Secondary Dataset on Contractual and Macroeconomic Determinants of Contract Renegotiation in Public-Private Partnership Infrastructure Projects (1995-2023)

This dataset supports a study of the contractual and macroeconomic determinants of contract renegotiation in public-private partnership (PPP) infrastructure projects, with concession duration examined as a moderating variable. It contains 4,680 project-level records covering PPP infrastructure projects that reached financial closure between 1995 and 2023 across low- and middle-income economies in all World Bank regions. The workbook contains two sheets. The PPP_Dataset sheet holds all project records arranged chronologically by financial closure year, with 22 variables: project identifiers and descriptors (country, region, income group, sector, subsector), contractual characteristics (contract type, BOT family indicator, competitive award method, government support, investment commitment in USD millions, concession duration), country-year macroeconomic and institutional conditions (real GDP growth, CPI inflation, exchange rate depreciation, Regulatory Quality), and renegotiation outcomes (binary RENEG indicator and a three-category outcome variable). Computed variables (log investment and mean-centered concession duration) are stored as live formulas. The Supplementary sheet documents data sources and provenance, provides a complete codebook for all 22 variables, and reports live-formula summary statistics. Project-level information is drawn from the World Bank Private Participation in Infrastructure (PPI) Project Database. Country-year macroeconomic indicators are taken from the World Bank World Development Indicators (GDP growth, NY.GDP.MKTP.KD.ZG; CPI inflation, FP.CPI.TOTL.ZG; official exchange rates, PA.NUS.FCRF) and institutional quality from the Worldwide Governance Indicators (Regulatory Quality, RQ.EST). Renegotiation coding follows incidence patterns established in the PPI-based renegotiation literature; overall incidence in the dataset is 18.48 percent, with the sector ordering (water highest, followed by transport, energy, and ICT) consistent with reported benchmarks.
