This paper studies wage-price dynamics in the context of a disequilibrium macro model where there are two Phillips (PC) curves, a wage PC and price PC. We adapt this framework but introduce a Kaldorian delay effect in wage dynamics whereby output and sales predate wage dynamics. Though along...

Peter Howitt is best known for his contributions to growth theory, but his work in short- run economics, which began with his Ph.D thesis and still continues, is important and deserves attention. It lies firmly in the Keynesian macro-disequilibrium tradition of Clower and Leijonhufvud, and for a...

Uncertainty is a challenge for monetary policy. This paper introduces model uncertainty into a behavioral New Keynesian DSGE framework to derive robust optimal monetary policies. We consider two potential forms of agents’ heterogeneity, which refer to two mechanisms of expectation formation...

This paper asks whether the post-Keynesian or New Keynesian paradigm provides a more realistic description of the effects of fiscal policy on output and consumption. I establish some macro and microeconomic stylized facts on fiscal multipliers and marginal propensities to consume based on the...

Professor Axel Leijonhufvud passed away few months ago, at the age of 89. Despite the fact that the contribution he made to economics has been widely recognized, his approach remains 'problematic' because of his dialogue and proximity with different streams of thought, and in particular with the...

We propose an easy-to-use search friction in the goods markets in medium-sized New Keynesian models. This friction allows increases in measured productivity in response to increases in expenditures via higher search effort from households. As a result markups can become procyclical and labor...
