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...

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...

Using a monetary search model, Rocheteau, Rupert and Wright (2007) show that the relationship between inflation and unemployment can be positive or negative depending on the primitives of the model. The key features are indivisible labor, nonseparable preferences and bargaining. Their results...

Fiscal policy has become quite controversial in the post-Keynesian era, the debate over the Obama stimulus package being a contentious recent example. Some pundits go so far as to take the position that macroeconomic theory has failed to meaningfully progress in terms of providing useful...

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...

Building a model with three imperfect markets - goods, labor and credit - representing a product's life-cycle, we find that goods market frictions drastically change the qualitative and quantitative dynamics of labor market variables. The calibrated model leads to a significant reduction in the...

Unemployment may depend on equilibrium in other markets than the labor markets. This paper adresses this old idea by introducing search frictions on several markets: in a model of credit and labor market imperfections as in Wasmer and Weil (2004), I further introduce search on the goods market....

This note proposes a growth model that is derived from the standard Solow growth model by replacing the neoclassical production function with Kaldor's technical progress function while maintaining a marginalist theory of factor prices in the spirit suggested by von Weizsäcker (1966, 1966b). The...
