Book excerpt: Now more than ever, policy evaluation is an important component in addressing the world's economic crisis. Before it can do so, the discipline must adapt to changing economic and political environments. The contributors address a basic question: What impact do crises have on evaluation and how can evaluation contribute in times of turbulence? Examining the state of evaluation today, the volume's editors cover a broad range of topics, including post-hoc evaluation; shifting economic paradigms; the World Bank Group's response to the global economic crisis; challenges in evaluating financial literacy; evaluating counter-terrorism programs; evaluation in the context of humanitarian crises; and why civil society organizations in sub-Saharan Africa matter in evaluating poverty interventions. The contributors explore the role of evaluation in the search for solutions to global instability. They recognize, however, that in order to address unprecedented crises, evaluation itself needs to be evaluated and updated as part of the process of change and reform. This volume is the latest in Transaction's well-respected Comparative Policy Evaluation series.
