On the contrary, innovative financing from the outset has been designed to generate additional resources for development, and not be used as a substitute for traditional resources, as stated in declarations adopted by the United Nations and in various conclusions of Leading Group meetings. The ‘niche’ idea behind innovative financing versus traditional official development assistance (used in sectors or economic approaches that are not sufficiently targeted by traditional assistance) is also in practice a guarantee. The measurement issue in official development assistance (which raises the question of perimeters selected by the OECD DAC for this aggregate, which is by nature heterogeneous) must also be separated from the additionality issue (i.e. of whether innovative financing actually complements traditional financing).
