Project outcomes vary much more within countries than between countries: country-level characteristics explain only 10–25 percent of project outcomes. Among macro variables, country growth and the policy environment are significantly positively correlated with project outcomes. Among micro variables, shorter project duration and the presence of additional financing are significantly correlated with better project outcomes. In addition, the track record of the project manager in delivering successful projects is highly significantly correlated with project outcomes. There are few significant differences between the two institutions in the relationship between these variables and project outcomes.en-USCC BY 3.0 IGOSOCIAL INCLUSIONPROJECT MANAGEMENTCOMMUNITIESDEVELOPMENT RESEARCHEQUITYSTRUCTURAL ADJUSTMENTSUPERVISIONACCOUNTINGAUTONOMYDEVELOPMENT ORGANIZATIONSDESCRIPTIONCOMPLEX PROJECTSINTERESTAID ALLOCATIONVALUEPROJECT COMPLETIONDEVELOPMENT BANKSSUSTAINABILITYBANKINDUSTRYFLEXIBILITYPROJECT MONITORINGPROGRAMSDEVELOPMENT ISSUESMONITORINGHEALTHIMPACTSDEVELOPMENT AIDSAMPLE SIZEPROJECTSPROJECTBORROWERSMULTILATERAL DEVELOPMENT BANKSINFRASTRUCTURE PROJECTSQUALITYECONOMIC ANALYSISDEVELOPMENT OBJECTIVESDEVELOPMENTICRPROJECT IMPLEMENTATIONLANDAIDSTATISTICSEVALUATIONTRAININGRISKTRANSPORTCONCESSIONAL LENDINGIMPACT EVALUATIONPRODUCTIVITYLENDINGCRITERIAPROJECT EVALUATIONINTERVENTIONSLOCAL GOVERNMENTINTERNATIONAL DEVELOPMENTINDICATORSRESEARCHIMPLEMENTATION COMPLETION REPORTLOANSOUTCOMESADBGOVERNMENTSOBJECTIVESFINANCEECONOMIC CONDITIONSPROJECT QUALITYSTRUCTURAL POLICIESINFRASTRUCTUREDEVELOPMENT POLICYDESIGNACTIONSBANKSDATA SETFISCALWorking PaperWorld Bank10.1596/1813-9450-7245
