It is time to take a fresh look at the PSWs and to ask some basic questions about their role and instruments. The aim of this essay is to raise issues that need to be addressed as we think about how PSWs should evolve and adapt to meet the formidable challenges ahead. These questions and the answers gained through careful research can help chart the right course and set the right expectations for MDB PSWs, DFIs, and impact investors generally.
The Asian Infrastructure Investment Bank (AIIB) has enjoyed considerable success in its young life. The challenge going forward is to translate this resounding political success into operational effectiveness and sound strategy. Given the political dimensions of this new institution, it is also worth considering what it will mean for other MDBs like the World Bank and the ADB. There are large questions of political leadership in the multilateral “system” but also an array of issues on which the AIIB could help shape a new system-wide approach, whether defined by some division of labor among the MDBs or by introducing institutional innovations.
