[Evaluation of public policies. SESPAS Report 2010]

Public policy evaluation is not always a mandatory task for administrations. A priori, the instruments for government intervention are chosen and calculated to maximize the social welfare function that should be implicit in the policies undertaken, or in the government's electoral program. However, it is surprising how the government sometimes acts without questioning whether institutional functioning and the corresponding public policies can effectively and efficiently achieve this objective. The absence of evaluation drains the scarce available resources towards ineffective and inefficient programs, which could be otherwise used in other initiatives with a greater impact on the population's welfare.
