This volume on the Classical–Keynesian approach to macroeconomics is an impressive tribute to Óscar Dejuán, a fine scholar and friend, reflecting his intellectual orientation—especially his advocacy of the classical surplus approach and Keynes’s principle of effective demand—and the breadth of his interests in production theory, income distribution, economic development, the history of economic thought, and input–output analysis.Heinz D. Kurz, University of Graz, AustriaA well-deserved book in honour of a great scholar, whose contributions have influenced and impacted a great many academics, including young scholars. This book is an essential read, and is rich with contributions from both young and well established authors. The editors have done Óscar Dejuán proud, with this collection of remarkable articles. Well done.Louis-Philippe Rochon, Laurentian University, CanadaThis Festschrift is a very exciting book that reflects Dejuán’s interests in several fields, including the revival of the surplus approach, the role of aggregate demand, growth theory, input-output analysis, monetary policy, and the history of economic thought. On each of these topics, the book collects very appealing and innovative contributions. It will be a must for all students and scholars interested in a pluralistic approach to economic theory and policyAntonella Stirati, Roma Tre University, Italy
