IDA is funded largely by contributions from the governments of its richer member countries. Additional funds come from IBRD's and IFC's income and from borrowers' repayments of earlier IDA credits.
Partners meet every three years to replenish IDA funds and review IDA's policies. The most recent replenishment of IDA's resources, the 17th (IDA17), was finalized in December 2013, resulting in a record replenishment size of special drawing rights (SDR) 34.6 billion ($52.1 billion) to finance projects over the three-year period from July 1, 2014, to June 30, 2017. To increase openness and help ensure that IDA's policies are responsive to country needs and circumstances, representatives of borrower countries from each IDA region have been invited to take part in the replenishment negotiations since IDA13.
In addition, since IDA13, background policy papers have been publicly released, as well as drafts of the replenishment reports before their finalization.
The World Bank's principal research unit is the Development Economics Vice Presidency (DEC). Unlike operations and network departments, which also undertake research, its mandate includes research that may be cross-country and across sectors and reach beyond specific regional units or sectors. DEC researchers provide cross-support to World Bank operations to help ensure that the Bank's policy advice is firmly grounded in current knowledge.
With nine programs, it produces the majority of the Bank's research and enjoys a high international profile. The work of DEC researchers appears in academic journals, the World Bank Policy Research Working Paper Series, books, blogs, and special publications such as the Policy Research Reports.
