This paper is a survey of practices andresults that have been observed in the implementation ofPBGs, drawing largely upon four in-depth Project PerformanceAssessment Reports undertaken by IEG, in Serbia, Macedonia,and Montenegro. It also draws upon IEG’s evaluations ofGhana’s Poverty Reduction Support Credits, which providebackground material on the 2015 Ghana PBG. A recent WorldBank review of the Albania PBG was also taken intoconsideration. The report draws on IEG’s technical analyses,coordinated with relevant units of the World Bank and,finally, interviews with a cross-section of World Bankstaff. It therefore represents an initial step in buildinggreater awareness of a relatively new and important tool indevelopment finance.
