The world's poor and dispossed could have no more articulate or insightful a champion among economists than Amartya Sen. By showing that the quality of our lives should be measured not by our wealth but by our freedom, his writings have revolutionized the theory and practice of development. The United Nations, in its own development work, has benefited immensely from the wisdom and good sense of Professor Sen's views. Kofi A. Annan, Secretary-General of the United Nations In this book, Amartya Sen develops elegantly, compactly, and yet broadly the concept that economic development is in its nature an increase in freedom. By historical examples, empirical evidence, and forceful and rigorous analysis, he shows how development, broadly and properly conceived, cannot be antagonistic to liberty but consists precisely in its increase.
