'Fleurbaey and Maniquet are among the outstanding scholars in the development of formal theories of social choice and justice today. Their many original contributions and synthesis, in the present volume, are masterly and go well beyond what can be said in the usual philosophical language. The concepts of fair and efficient resource allocations have been enriched by their work.' Kenneth J. Arrow, Stanford University and Nobel Laureate in Economics
