DSGE models are typically estimated assuming the existence of certain structural shocks that drive macroeconomic fluctuations. We analyze the consequences of introducing nonfundamental shocks for the estimation of DSGE model parameters and propose a method to select the structural shocks driving...

Abstract This paper conducts an empirical investigation of the effects of temporary versus persistent fiscal policy shocks. Using data from the US I show that short lived fiscal expansions have a positive effect on output and consumption; while persistent fiscal shocks generate negative effects...

Apart from a priori assumptions on instantaneous or long run effects of structural shocks, sign restrictions have become a prominent means for structural vector autoregressive (SVAR) analysis. Moreover, second order heterogeneity of systems of times series can be fruitfully exploited for...

In this paper we introduce the general setting of a multivariate time series autoregressive model with stochastic time-varying coefficients and time-varying conditional variance of the error process. This allows modeling VAR dynamics for non-stationary times series and estimation of time varying...

This paper discusses comovement between inflation and output in the euro area. The strength of the comovement may not be apparent at first sight, but is clear at business cycle frequencies. Our results suggest that at business cycle frequency, the output and core inflation comovement is high and...

What are the drivers of business cycle fluctuations? And how many are there? By documenting strong and predictable co-movement of real variables during the business cycle in a sample of advanced economies, we argue that most business cycle fluctuations are driven by one major factor. The...

In this paper we set up a macroeconomic model designed to describe small open economy enduring political uncertainty arising from split of a country into two independent parts. The findings in the paper indicate, stabilization of asset markets in either country at the post-secession era depends...

We use financial intraday data to identify monetary policy surprises in the euro area. We find that monetary policy statements and press conferences after European Central Bank (ECB) Governing Council meetings convey information that moves the yield curve far out. Moreover, the nature of the...

This study establishes the first empirical evidence of the impact of economic uncertainty shocks on industry-level investment, output and employment in Australia. We find the Construction and Financial and Insurance Services industries are the most impacted by a shock to economic uncertainty....

Compared with identification of monetary policy shocks, Identification of fiscal policies shocks are equally important, but there are insufficient in related research of China. Therefore, the paper chooses Sign Restriction to identify fiscal policies shocks of China. After we discuss...
