The Great Depression of the 1930s with its dramatic unemployment rates was one of the most striking economic events of the past century. It shook economists' beliefs in the existence of self-adjusting forces and prompted Keynes to write his masterwork, The General Theory of Employment, Interest and Money.

Involuntary unemployment was the central concept of Keynes' book. However, after having been considered the sine qua non of economics for decades, it has gradually disappeared from textbooks and research. This book recounts and ponders this demise, asking whether the abandonment of the concept of involuntary unemployment is the manifestation of some inner defect of recent economic theory or is rather due to some intrinsic weakness of the concept itself, which makes it of little use when it comes to economic theorising.

In order to disentangle these issues, the author critically reviews the different explanations of involuntary unemployment that have been offered from Keynes upto the end of the 1980s. After consideringThe General Theory, the author studies the works of pioneering macroeconomists such as Hicks, Modigliani, Lange, Leontief, Tobin, Klein and Hansen. An examination of the 're-appraisal of Keynes' and of the so-called disequilibrium school is followed by a discussion of Friedman's and Lucas' anti-Keynesian attack. The final part of the book investigates a series of models purporting to revive the Keynesian project, namely implicit contract, efficiency wages, insider-outsider, coordination failures, and imperfect competition.

The Great Depression of the 1930s with its dramatic unemployment rates was one of the most striking economic events of the past century. It shook economists' belief in the existence of self-adjusting forces and prompted Keynes to write his masterwork, The General Theory of Employment, Interest and Money (1936). This book studies the evolution of macroeconomics viewed through the window of involuntary unemployment.
Involuntary unemployment has played a central role in the development of macroeconomics and has also been the object of heated debates, being defended and attacked by prominent economists with equal vehemence. However, this concept has gradually disappeared from textbooks and research. This book recounts and ponders this demise, asking is this a manifestation of a defect of economic theory or is it rather that the involuntary unemployment concept is of little use when it comes to economic theory?

The final section of the book investigates key topics such as different New Keynesian models, efficiency wages, and imperfect competition models.

This book retraces the history of macroeconomics from Keynes's General Theory to the present. Central to it is the contrast between a Keynesian era and a Lucasian - or dynamic stochastic general equilibrium (DSGE) - era, each ruled by distinct methodological standards. In the Keynesian era, the book studies the following theories: Keynesian macroeconomics, monetarism, disequilibrium macroeconomics (Patinkin, Leijongufvud and Clower), non-Walrasian equilibrium models, and first-generation new Keynesian models. Three stages are identified in the DSGE era: new classical macroeconomics (Lucas), RBC modelling, and second-generation new Keynesian modeling. The book also examines a few selected works aimed at presenting alternatives to Lucasian macroeconomics. While not eschewing analytical content, Michel De Vroey focuses on substantive assessments, and the models studied are presented in a pedagogical and vivid yet critical way.

One of the fruits of the revival of socialist economic theory over the past decade has been a wide-ranging debate about the validity of Marx's labour theory of value. At the heart of the discussion stands the theoretical work of Piero Sraffa and the conclusions drawn from it by such economists as Ian Steedman. Initially confined to a relatively narrow circle of specialists, the controversy about value theory has since spread to wider circles of the left. But although general awareness that the stakes of the dispute are of concern to all socialists is now extensive, understanding of the issues involved has remained more restricted than need be. This volume presents, for the first time, a comprehensive yet accessible overview of the discussion. The essays discuss not only the value debate itself, but also its relevance to such issues as capitalist crisis, the theory of exploitation, and historical materialism. Comprehensible to the non-specialist, but without sacrificing rigour or oversimplifying the issues, the articles assembled here offer a definitive summary of the current state of one of the crucial aspects of Marxist thought.
