Abstract

This study examines the presence of abnormally low bids in public-private partnership (PPP) project tenders across Latin America. To this end, a representative database of PPP processes in Latin America was developed. Surprisingly, the findings indicate a notable absence of abnormally low bids. This result stands in stark contrast to recent studies. The analysis of 122 PPP projects spanning diverse countries and sectors provides a foundation for constructing a statistical test to identify abnormally low bids.

Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
