Development finance is an issue that typically concerns developing countries. This is where numerous, grave socio-economic problems persist, including – and not among the least – the need for stable development finance in higher quantity and of higher quality. However, development finance could also be used today as a growth-enhancing concept applicable to advanced economies, to boost their growth and help their social inclusion. It could contribute to rebalancing macroeconomic policies and move them towards a new “possible trinity”: growth based on higher productivity, growth that favours stronger social inclusion and growth that is friendlier to the environment.
