It is not a question of stimulus against public investments.
If stimulus one needs to make certain that these go to those who provide the most effective demand creation in sustainable sectors; if infrastructure these have to create employment in the short term and serve as support for long term sustainable growth.
But, whatever alternative is chosen, there is a need to follow sound implementation principles. For instance, in infrastructure projects and in order to guarantee ownership, these should be proposed by the States municipalities or even private corporations; for transparency these should be approved by a public committee after a brief evaluation of the projects on what they offer in terms of jobs and sustainable growth; and, finally, for accountability, the projects should only receive the funds in strict pre-specified terms and conditions, cash on delivery.
