Our paper studies two attempts at integrating unemployment in macroeconomics. The first, due to Diamond, consists in a search model exhibiting multiple equilibria. The second is due to Andolfatto and Merz who, more or less simultaneously, were able to integrate the matching function in RBC...

Academic macroeconomics as it has been practiced for the last three decades has a bad reputation, especially after the onset of the 2008 recession. The aim of this paper is to reflect on this state of affairs. To begin, I draw a comparison between Keynesian and Lucasian macroeconomics, bringing...

In this review article of Backhouse and Boianovsky’s book, Transforming modern macroeconomics. Exploring disequilibrium microfoundations, 1956-2003, I make the following points: (a) Backhouse and Boianovsky’s too broad understanding of the disequilibrium approach results in their bringing...

The notion of frictional unemployment first arose in the writings of Beveridge, Pigou and Hicks. Why did it fail at the time to grow into a fully fledged theory ? Our answer is simple. This failure was due to the fact these economists were unwilling and/or unable to go beyond the then-prevailing...

The standard view about the relation between the Marshallian and the Walrasian approaches is that they are complementary to each other.

The aim of the present paper is to assess the new classical/real business cycle revolution, which dethroned Keynesian macroeconomics. In its first part, I critically discuss the microfoundations requirement that constitutes a cornerstone of the new approach and suggest an alternative, softer,...

The aim of this paper is to elucidate Keynes's Marshallian lineage. I argue that the result of bringing out the Marshallian antecedents of the General Theory highlights Keynes’s failure to achieve the theoretical project he was striving at, namely to demonstrate an involuntary unemployment...

This paper concerns a neglected aspect of Lucas’s work: his methodological writings, published and unpublished. Particular attention is paid to his views on the relationship between theory and ideology. I start by setting out Lucas’s non-standard conception of theory: to him, a theory and a...
