Recent developments in the political, scientific and economic debate will have important repercussions on economic policy and welfare, many of them not reflected in traditional GDP measures and in economic policy. Thus it is of critical importance to develop and to use new approaches able to compare policy scenarios for their effectiveness, their efficiency, their enforceability and other dimensions. Quantitative methodology has to assess the relative performance of different policy scenarios taking into account their long-term economic, social and environmental impacts. The methodology based on Data Envelopment Analysis (DEA) and Multi Criteria Analysis (MCA) provides a promising comparison framework.
