Shocks to monetary and fiscal policy have played a major role in public debt developments in the OECD countries since the mid-1970s. According to the applied VAR approach, these shocks, taken together, explained, on average, about half of the forecast error variation in the debt to GDP ratio,...

In this essay we study the optimal noncoordinated fiscal policy in a monetary union, where a common and independent monetary authority commits to optimally set the union-wide nominal interest rate. The national governments in the monetary union implement independent fiscal policies by choosing...

We study the effect of collateral eligibility of corporate loans on the pricing of these loans by banks in Finland. Speciftcally, we investigate whether loans that are pledgeable as collateral for central bank borrowing have lower liquidity premia and thus lower interest rates. For...

Canzoneri and Diba (2004) show that the Taylor principle is not a panacea for equilibrium determinacy in a model where bonds and money provide liquidity services to households. We consider a cashless New Keynesian model with two types of government bonds. One bond provides transaction services,...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

This paper analyzes euro area and U.S. inflation dynamics since the beginning of the 1990s by estimating New Keynesian hybrid Phillips curves with time-varying parameters. We measure inflation expectations by subjective forecasts from Consensus Economics survey and so do not assume rational...

This paper studies fiscal policy in a New Keynesian DSGE model with endogenous technology growth in which scarring can occur endogenously through hysteresis effects in TFP. Both demand- and supply-driven recessions can weaken investment in R&D and technology adoption, thus depressing the...

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,...

This paper estimates regime-switching monetary policy rules featuring trend inflation using post-WWII US data. We find evidence in favour of regime shifts and time-variation of the inflation target. We also find a drop in the inflation gap persistence when entering the Great Moderation sample....

According to the long-run Taylor principle (Davig and Leeper, 2007), a central bank can deviate to a passive monetary policy and still obtain equilibrium uniqueness if a sufficiently aggressive monetary policy is expected for the future. Does this principle hold true when both monetary and...
