Improvement of the world’s livestock industry necessitates input from many directions. Planning by a host of national and international agencies is required in order to provide optimal stimulus in very diverse areas ranging from formulation of laws and incentives that stimulate competition yet prevent undue competition, to the optimal provision of credit. Planning is needed to carry out a complex array of interrelated research. The purpose of this book is specifically tasked with setting forth frameworks and methods for evaluation of investments and associated economic decision-making in the livestock industries of developing countries. Economists will find this book useful because it synthesizes .much material into a cohesive whole–material that is often presented in a cursory manner or overlooked as emphasis has shifted to sophisticated quantitative techniques.
