We analyse the effectiveness of optimal simple and implementable monetary and fiscal policy rules in stabilising economic activity, inflation and government debt in face of an occasionally binding lower bound on the nominal interest rate in a New Keynesian model. We show that, within the...

This paper shows that debt-financed fiscal multipliers vary depending on the maturity of debt issued to finance spending. Utilizing state-dependent SVAR models and local projections for post-war US data, we show that a fiscal expansion financed with short term debt increases output more than one...

In this paper, we reconsider Minsky's financial instability hypothesis from the point of view of mathematical macrodynamic modeling. We start from a simple prototype small scale model of private debt and income with fixed prices. This system is similar to the Lotka-Volterra predator-prey system,...

Real wages in the United States have continued to stagnate in the years since the end of the Great Recession. This paper attributes this stagnation directly to the prolonged period of high unemployment. It notes research showing that the only period of sustained wage growth for most of the...

We revisit the theoretical underpinnings of the monetary policy consensus before the Great Recession. We highlight how they resulted from New Keynesian dynamic stochastic general equilibrium (DSGE) models that (i) neglected the actual process of coordination in markets, (ii) saw price rigidity...

Lieferengpässe im Zuge der Covid-19-Pandemie und der Krieg Russlands gegen die Ukraine haben dazu beigetragen, dass die Inflationsraten wieder angestiegen sind. Wir argumentieren, dass sich dadurch sechs strukturelle Faktoren verstärkt haben, warum die Inflation und auch höhere Zinsen nicht...

This paper studies price stability and debt sustainability when the real rate exceeds trend growth (r g) in a New Keynesian model with endogenous technology growth through R&D. Under debt-stabilizing ("passive") fiscal policy the Taylor principle is not sufficient for determinacy. Instead,...

We examine the relationship between inflation and fiscal sustainability with a two-step approach. In the first step, we estimate to estimate a country-specific time-varying measure of fiscal sustainability using the fiscal reaction function. This function captures the response of the primary...

DSGE models based on New Keynesian principles, which have been extended to allow for banking, the zero lower bound on interest rates (ZLB), and varying price duration, can account well for recent macroeconomic behavior across a variety of economies. These models Önd that active Öscal policy...
