Building on the first-hand data collection, we aim to systematically identify specific public policy areas where PDBs operate in practice. Previously, we have identified eight official mandates of PDBs, namely, the flexible mandate, agriculture, international trade, housing, infrastructure, international financing of private sector development, local government, and micro, small and medium-sized enterprise. Yet, little is known what are specific public policy areas engaged by PDBs with a flexible mandate and whether PDBs with a single official mandate engage in other public policy areas. Our present report aims to fill the gap. We aim to answer two research questions: first, what are the frequency of public policy areas pursued by PDBs; second, what types of PDBs are more likely to engage in a specific public policy area.
