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...

Keynesian economics dominated economic thought and macroeconomic policy-making in the 1950s and 1960s. However, the diffusion of Keynesian economics has been uneven. In this paper, we compare the spread of Keynesian economics in two continental European countries: Belgium and Italy. We focus on...

Alexandre Lamfalussy has been highly influential in the process of European monetary and financial unification. In this paper we will analyse the work of the "Young Lamfalussy" (from the mid 1950s to the mid 1960s). Lamfalussy started his career as an academic, focusing on growth theory and...

After a brief review of classical, Keynesian, New Classical and New Keynesian theories of macroeconomic policy, we assess whether New Keynesian Economics captures the quintessential features stressed by J.M. Keynes. Particular attention is paid to Keynesian features omitted in New Keynesian...

It is often said that after the crisis economic textbooks have to be rewritten. However, as surveys show, almost all professors continue using the standard IS-LM/AS-AD model as the workhorse for undergraduate training. This paper shows that the IS-LM/AS-AD model is not only full of obvious...

Milton Friedman's contributions to and influence on macroeconomics are discussed, beginning with his work on the consumption function and the demand for money, not to mention monetary history, which helped to undermine the post World War 2 Keynesian consensus in the area. His inter-related...

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...

This paper studies a New Keynesian model in which monetary policy may switch between regimes. We derive sufficient conditions for indeterminacy that are easy to implement and we show that the necessary and sufficient condition for determinacy, provided by Davig and Leeper, is necessary but not...

Conventional wisdom suggests that nominal, demand-side shocks have only temporary effects on real macroeconomic magnitudes and that the duration of their effects depends on the degree of nominal inertia. It is also argued that, in the absence of unit roots, temporary supply-side shocks also have...
