For over fifty years project analysis techniques have been applied in the assessment of development projects where poorly designed and appraised projects can waste scarce resources. This study examines the continued relevance of this approach, assesses methodological developments over this period and investigates current practical problems in the application of these techniques. This major work brings together authors with experience of both academic and operational project work to focus on issues such as the shadow exchange rate, the shadow wage, the discount rate and assessment of poverty impact and risk, as well as problems relating to specific sectors covering environmental projects, transport, education and health. There are also general chapters on the experience of semi-input–output-based estimation of shadow prices and the relevance of shadow pricing techniques to the context of developed economies in the EU. An overview by the editors sets out the evolution of the literature and highlights current issues. The general conclusion is that project analysis techniques remain relevant, albeit within a very different development context to that in which they were originally envisaged to be applied. With new perspectives on key economic parameters, this book will appeal to academics working on development, officials involved with project aid programmes, postgraduate students of development and professional economists working on development projects.
