This paper investigates how the ordering of variables affects properties of the time-varying covariance matrix in the Cholesky multivariate stochastic volatility model. It establishes that systematically different dynamic restrictions are imposed when the ratio of volatilities is time-varying....

We represent the dynamic relation among variables in vector autoregressive (VAR) models as directed graphs. Based on these graphs, we identify so-called strongly connected components (SCCs). Using this graphical representation, we consider the problem of variable selection. We use the relations...

In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroskedasticity is occasionally allowed for in inference, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change...

Incorporating arbitrage-free term-structure dynamics into a semi-structural macro-model, we jointly estimate the real equilibrium interest rate (r*), trend inflation, and term premia for the United States and the euro area, using a Bayesian approach. The natural real rate and trend inflation are...

The present paper discourses on how European integration and gradual enlargement has affected the synchronicity in business cycles in EU regions. The analysis, which is conducted on annual data at the NUTSII level, is based on the following grounds: First, it examines the degree of synchronicity...

Monetary responses to financial stress have recently become an important issue in macroeconomic and policy discussions in the USA as well as in the EU. In this paper, the authors study two regimes of monetary responses. While the fundamentals of an economy are assumed to have a long-run...
