Mapping of Instruments and Incentives for Infrastructure Financing

Traditionally, infrastructure investments have been financed with public funds. Governments were the main actor in this field, given the inherent public good nature of infrastructure and the positive externalities often generated by such facilities. However, public deficits, increased public debt to GDP ratios and, at times, the inability of the public sector to deliver efficient investment spending, have in many economies led to a reduction in the level of public funds allocated to infrastructure. Budgetary pressures have been compounded in some cases by the need to repair bank balance sheets and rebuild capital and liquidity buffers, owing in part to strengthened prudential regulation in the banking sector. As a consequence, it is increasingly acknowledged that alternative sources of financing are needed to support infrastructure development.
