This text addresses the understanding and alleviation of poverty, inequality, and inequity using a unique and broad mix of concepts, measurement methods, statistical tools, software, and practical exercises. Most of the book's measurement and statistical tools have been programmed in DAD, a well established and widely available free software program that has been tailored especially for income distribution analysis and is used by scholars, researchers, and analysts in nearly 100 countries worldwide. It requires basic understanding of calculus and statistics. There are examples and exercises using real data.

This book provides a general framework for the use of theoretical contributions in empirical works, addressing the question of what is the effect of a price change on household well-being. This simple question is one of the most relevant and controversial questions in microeconomic theory and one of the main sources of errors in empirical economics. In particular, this book aims to 1) Review the essential microeconomics literature since the first seminal papers by Hicks in the 1930s; 2) Organize and simplify this literature in a way that can be easily used by analysts with different backgrounds providing algebraic, geometric and computational illustrations; 3) identify and measure the essential differences across methods and test how these differences affect empirical results; 4) Provide guidelines for the use of alternative approaches under imperfect information on utility, demand systems, elasticities and more generally incomes and quantities; 5) Provide computational codes in Stata for the application of all methods. The focus of the book is on developing economies and the poor, and the assumptions made will relate primarily to these countries and group of people, presumably the main policy focus of international organizations and national governments.
