In expectations-driven liquidity traps, a higher inflation target is associated with lower inflation and consumption. As a result, introducing the possibility of expectations-driven liquidity traps to an otherwise standard model lowers the optimal inflation target. Using a calibrated New...

I characterize optimal monetary and fiscal policy in a stochastic New Keynesian model when nominal interest rates may occasionally hit the zero lower bound. The benevolent policymaker controls the short-term nominal interest rate and the level of government spending. Under discretionary policy,...

This paper investigates the impact of fiscal shocks on inflation, using a large panel of 139 countries over the period 1970–2021. First, both headline and core measures of inflation increase in response to expansionary shifts in the fiscal policy stance. Second, we split the sample and observe...

Concerns of prolonged stagnation periods with near-zero interest rates and deflation have become widespread in many advanced economies. We build a theoretical framework that rationalizes two theories of low interest rates: expectations-trap and secular stagnation in a unified setting. We...

Are government spending shocks inflationary at the zero lower bound (ZLB)? Despite the importance of the inflation channel in amplifying government spending multipliers at the ZLB, empirical studies have not provided a clear answer to this question. Exploiting newly constructed high-frequency...

Large risk shocks give rise to cost-push effects in the canonical New Keynesian model. At the same time, monetary policy becomes less effective. Therefore, stochastic volatility introduces occasional trade-offs for monetary policy between inflation and output gap stabilisation. The cost-push...

In this paper, we analyse nominal exchange rate and price dynamics after risk shocks with short-term interest rates constrained by the zero lower bound (ZLB). We show with a stylized theoretical model that temporary risk shocks may lead to permanent shifts of the exchange rate and the price...

Zimbabwe has recently experienced record hyperinflation of 80 billion percent a month. This paper uses new data from Zimbabwe to investigate money demand under hyperinflation using an ARDL estimation for the period 1980-2008. The results produce plausible convergence rates and long- run...
