This paper discusses the following two hypotheses. The first one is based on the epistemological proposal which we have named the principle of discontinuity. It asserts that certain developments in the history of economic thought involve theoretical breaks which can only be fully explained by...

The monetary economy has properties that cannot be analyzed using the tools of today's dynamic general equilibrium analysis. Keynes's economics, far from being an aberration in the otherwise orderly evolution of modern macroeconomics from Adam Smith's ideas about the invisible hand, was a major...

This paper examines Robert E. Lucas's views on the relationship of macroeconomics to real world economic phenomena, and on Keynes's place in its history, suggesting that these stem from a particular and debatable understanding of how the subdiscipline has evolved. It considers some implications...

Orthodox and heterodox theories of financial crises are hereby compared from a theoretical viewpoint, with emphasis on their genesis. The former view (represented by the fourthgeneration models of Paul Krugman) reflects the neoclassical vision whereby turbulence is an exception; the latter...

The Financial Crisis of 2008, and the Great Recession in its wake, have shaken up macroeconomics. The paradigm of the "New" Neoclassical Synthesis, which seemed to provide a robust framework of analysis for short-run macro not long ago, fails to capture key elements of the recent crisis. This...

This paper presents an overview of different models which explain financial crises, with the aim of understanding economic developments during and possibly after the Great Recession. In the first part approaches based on efficient markets and rational expectations hypotheses are analyzed, which...

Keynes is back. President Obama's economic stimulus package is based on the premise that we can spend our way out of recession. It is an application of the Keynesian multiplier theory, which was expounded in Keynes' 1936 economic treatise, The General Theory of Employment, Interest and Money....

Krugman has recently revitalized IS-LM with a number of succinct analytical pieces on his blog. The reverberations were remarkable. Economists, however, are known often not grasp the full content of their own and, a fortiori, of others' models. This happened to Keynes in the days of high theory...
