This paper proposes a novel approach to introduce time-variation in structural parameters of DSGE models. Structural parameters are allowed to evolve over time via an observation-driven updating equation. The estimation of the resulting DSGE model can be easily performed by maximum likelihood...

This paper examines the effects of monetary policy shocks on UK regional economic growth and dispersion in a novel Constrained Mixed Frequency Vector Autoregressive framework. Compared to a standard MFVAR, the model partially accounts for missing quarterly observations for regional growth by...

The empirical literature using vector autoregressive models to assess the effects of fiscal policy shocks strongly disagrees on even the qualitative response of key macroeconomic variables to government spending and tax shocks. We provide new evidence for the U.S. over the period 1955-2006. We...

An n-variable structural vector auto-regression (SVAR) can be identified (up to shock order) from the evolution of the residual covariance across time if the structural shocks exhibit heteroskedasticity (Rigobon (2003), Sentana and Fiorentini (2001)). However, the path of residual covariances...

We explore a century-long dataset with a Markov-switching structural VAR to estimate state-dependent government spending multipliers. We show that the multiplier values are statistically larger during recessions than during expansions. However, the multipliers are always smaller than 1. Our...

We study the transmission of fiscal policy under imperfect information where government spending is composed by permanent and transitory components. Agents learn about the previous processes by only observing overall public spending and a noisy signal. Under this setting and employing maximum...

Accurately estimating the government spending multiplier is important so that fiscal policies can be used appropriately when recessions hit the economy. To fill the gap between the frontier research of calculating the government spending multiplier and current Korean research, and to estimate a...

This paper estimates the impact of government spending shocks on economic activity during periods of high and low uncertainty and during periods of boom and recession. We find that government spending shocks have larger impacts on output in booms than in recessions and larger impacts during...

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....

We investigate whether the macroeconomic effects of government spending shocks vary with the level of uncertainty. Using postwar US data and a Self-Exciting Interacted VAR (SEIVAR) model, we find that fiscal spending has positive output effects in tranquil times but is contractionary during...
