The Transformation of macroeconomic policy and research is Prescott's 2004 Nobel Prize lecture. It sets out the method and significance of micro-founded, forward-looking, dynamic-equilibrium models as originated by Kydland, Prescott, Lucas and others, and widely adopted as cheap computing power becomes available. Assess the impact on use of macro models for policymaking, with particular attention to time consistency and credible commitment. It is complemented by the shorter, more empirical 'Quantitative Aggregate Theory' by co-laureate Finn Kydland, available from the same site. Both in video as well as text form.
