This paper explores the ability of the New-Keynesian (NK) model to explain the recent periods of quiet and stable inflation at near-zero nominal interest rates. We show how (conventional and unconventional) monetary policy shocks enlarge the ability to explain the facts, such that the theory...

This paper explores the ability of the New Keynesian (NK) model to explain the recent periods of quiet and stable inflation at near-zero nominal interest rates. We show that temporary and permanent shocks to the natural rate (and inflation) are sufficient for the ability of the simple NK model...

Skyrocketing debt-to-GDP ratios in the wake of the global coronavirus pandemic again brought the question of fiscal sustainability into focus. This paper evaluates sustainable monetary and fiscal policy coordination in high debt scenarios. In particular, it compares policy interactions in NK...

This chapter aims to provide a hands-on approach to New Keynesian models and their uses for macroeconomic policy analysis. It starts by reviewing the origins of the New Keynesian approach, the key model ingredients and representative models. Building blocks of current-generation dynamic...

This paper presents a new solution method for dynamic equilibrium models. The proposed method approximates the solution by polynomials that zero the residual function and its derivatives at a given point x0. It is essentially a projection-type algorithm, but is significantly faster than standard...

In this paper, I embed the fiscal theory of the price level (FTPL) in a simple continuous-time New Keynesian (NK) model with capital and capital adjustment costs. I offer an elaborate analysis of determinacy, model dynamics, transmission channels and the importance of capital adjustment costs in...

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...
