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...

This paper provides new evidence on the effects of government spending shocks and the fiscal transmission mechanism in the euro area for the period 1980-2008. Our contribution is two-fold. First, we investigate changes in the macroeconomic impact of government spending shocks using time-varying...

We investigate the effects of fiscal policy surprises for US data, using vector autoregressions. We overcome the difficulties that changes in fiscal policy may manifest themselves in variables other than fiscal variables first and that fiscal variables may respond "automatically" to business...

This paper decomposes government spending into its temporary and permanent components using Baker’s et. al. economic policy uncertainty (EPU) in a bivariate SVAR setting with long-run constraints, a la Blanchard and Quah (1989). To illustrate the applicability of the bivariate moving average...

We investigate the effects of UK monetary policy from 1974-2001 using a structural vector autoregression with quarterly data. We adapt Uhlig's (2001) sign restriction identification methodology and show that shocks which can reasonably be described as monetary policy shocks have played a very...

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...

I estimate the effect of U.S. government spending and tax shocks on Canada and the U.K. from 1975 to 2014, and on Japan from 1979 to 2014. Spending and tax shocks are identified using sign restrictions on the impulse responses from a vector autoregression (VAR). I find that spillover effects of...

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...

We identify government spending news and surprise shocks based on the Survey of Professional Forecasters (SPF) data. After an analytical and empirical clarification of the natures of two news measures in Ramey (2011b), we show that a measure of the news shock for the recent sample period is...
