This paper estimates the interaction between monetary- and fiscal policy using a structural VAR model with time-varying parameters. For demand and supply shocks, the two policies are estimated to be complementary, while for monetary and fiscal policies shocks the two policies act as substitutes....

Fiscal multipliers provide a way of quantifying the GDP gain for a given (discretionary) fiscal policy intervention. I compute government consumption multipliers for New Zealand, in normal times and when monetary policy is constrained at the effective lower bound, using an estimated...

We contribute to the growing empirical literature on monetary and fiscal interactions by applying a sign restriction identification scheme to a structural TVP-VAR in order to disentangle and evaluate the policy shocks and policy transmissions. This in turn allows us to study the Great Recession...

Locating the appropriate degree of interaction between fiscal and monetary policy plays an important role in ensuring economic stability. Their joint impact is, however, still unclear. We observe significant differences in the transmission of shocks, in particular between the Great Recession and...

We propose a novel framework where forward guidance (FG) is endogenously determined. Our model assumes that a monetary authority solves an optimal policy problem under commitment at the zero-lower bound. FG derives from two sources: 1. from commiting to keep interest rates low at the exit of the...

When the government issues long-term bonds, the optimal time-consistent fiscal and monetary policy is to consolidate debt in a liquidity trap by increasing taxes and by taming public spending. This prescription is at odds with large deficit-spending undertaken in the US during previous liquidity...

Optimal monetary and fiscal policy are jointly analyzed in a heterogeneous two-agents New Keynesian environment, where fiscal policy is modeled in the form of lump-sum transfers set by the government. The main result is that transfer policy does not serve as a substitute for forward guidance -...

How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...

Can the central bank credibly commit to keeping the nominal interest rate low for an extended period of time in the aftermath of a deep recession? By analyzing credible plans in a sticky-price economy with occasionally binding zero lower bound constraints, I find that the answer is yes if...
