Promoting Pro-Poor Growth: Practical Guide to EX ANTE Poverty Impact Assessment, OECD, 2007

    Guiding policy choice among interventions according to their likely impact on poverty reduction is a critical dimension of the pro-poor growth agenda. Without an ex ante assessment of likely distributional impacts, both policies and programmes often fail to achieve the desired pro-poor impacts. Evidence-based decision making is only possible if we are aware of how different socio-economic groups, women and men, might be affected by interventions. Based on such an assessment, decision makers are better placed to decide which interventions are expected to be most effective and how to increase their pro-poor impacts.

    This practical guide to ex ante Poverty Impact Assessment (PIA) reflects empirical evidence in the application of the PIA approach. It is designed to assist practitioners and decision makers to understand, plan and execute a PIA. It suggests a standardised but flexible analytical framework for undertaking a PIA. While focussing on ex ante, the approach can also be applied to ex post PIA. The guide comprises three main chapters:
    i) Chapter 1 explains the rationale, outline and key elements for ex ante PIA.
    ii) Chapter 2 explains the results chain being analysed, the conceptual framework and process for a PIA.
    iii) Chapter 3 provides practical guidance on how a PIA may be implemented.

    Methods for info gathering
    PIA is based on balancing quantitative and qualitative information to achieve a sound and reliable assessment. It draws mostly on already existing information sources. Where these are insufficient, additional data might need to be collected.
