Evaluating the Impact of Development Projects on Poverty: A Handbook for Practitioners (Directions in Development (Washington, D.C.).)

Despite the billions of dollars spent on development assistance each year, there is still very little known about the actual impact of projects on the poor. There is broad evidence on the benefits of economic growth, investments in human capital, and the provision of safety nets for the poor. But for a specific program or project in a given country, is the intervention producing the intended benefits and what was the overall impact on the population? Could the program or project be better designed to achieve the intended outcomes? Are resources being spent efficiently? These are the types of questions that can only be answered through an impact evaluation, an approach which measures the outcomes of a program intervention in isolation of other possible factors. This handbook seeks to provide project managers and policy analysts with the tools needed for evaluating project impact. It is aimed at readers with a general knowledge of statistics. For some of the more in-depth statistical methods discussed, the reader is referred to the technical literature on the topic. Chapter 1 presents an overview of concepts and methods. Chapter 2 discusses key steps and related issues to consider in implementation. Chapter 3 illustrates various analytical techniques through a case study. Chapter 4 includes a discussion of lessons learned from a rich set of 'good practice' evaluations of poverty projects which have been reviewed for this handbook. Very little is known about the actual impact of projects on the poor. Many are reluctant to carry out impact evaluations because they are deemed expensive, time consuming, and technically complex, and because the findings can be politically sensitive. Yet a rigorous evaluation can be powerful in assessing the appropriateness and effectiveness of programs. Evaluating impact is particularly critical in developing where resources are scarce and every dollar spent should aim to maximize its impact on poverty reduction. This handbook seeks to provide project managers and policy analysts with the tools needed for evaluating project impact. It is aimed at readers with a general knowledge of statistics. Chapter 1 presents an overview of concepts and methods, Chapter 2 discusses key steps and related issues to consider in implementation, Chapter 3 illustrates various analytical techniques through a case study, and Chapter 4 includes a discussion of lessons that have been reviewed for this handbook. The case studies, included in Annex I, were selected from a range of evaluations carried out by the Bank, other donor agencies, research institutions, and private consulting firms. Also included in the annexes are samples of the main components that would be necessary in planning any impact evaluation - sample terms of reference, a budget, impact indicators, a log frame, and a matrix of analysis Evaluating impact is particularly critical in developing countries where resources are scarce and every dollar spent should aim to maximize its impact on poverty reduction.
