We also investigate how political affinity interacts with government support to impact delays in project initiation. The analysis encompasses 2,902 projects across 84 developing economies, from 1985 to 2021, sourced from the World Bank. The findings highlight the significance of these factors in starting projects on time, offering valuable insights for project stakeholders.2025http://zaguan.unizar.es/record/16318410.1080/14719037.2025.2561112http://zaguan.unizar.es/record/163184oai:zaguan.unizar.es:163184Public Management Review (2025), 1-33All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/closedAccess
