Comparison of bootstrap confidence intervals for impulse responses of German monetary systems
Benkwitz, Alexander; Lütkepohl, Helmut; Wolters, Jürgen - 1999
It is argued that standard impulse response analysis based on vector autoregressive models has a number of shortcomings. Although the impulse responses are estimated quantities, measures for sampling variability such as confidence intervals are often not provided. If confidence intervals are...

Bootstrapping impulse responses in VAR analyses
Lütkepohl, Helmut - 2000
Because the parameters of vector autoregressive processes are often difficult to interpret directly, econometricians use quantities derived from the parameters to disentangle the relationships between the variables. Bootstrap methods are often used for inference on the derived quantities....

Lag selection in subset VAR models with an application to a US monetary system
Brüggemann, Ralf; Lütkepohl, Helmut - 2000
Alternative modeling strategies for specifying subset VAR models are considered. It is shown that under certain conditions a testing procedure based on t-ratios is equivalent to sequentially eliminating lags that lead to the largest improvement in a prespecified model selection criterion. A...

Estimation and testing for varying coefficients in additive models with marginal integration
Yang, Lijian; Härdle, Wolfgang; Park, Byeong U. - 2002
We propose marginal integration estimation and testing methods for the coefficients of varying coefficient multivariate … regression model. Asymptotic distribution theory is developed for the estimation method which enjoys the same rate of convergence … as univariate function estimation. For the test statistic, asymptotic normal theory is established. These theoretical …

Local power of likelihood ratio tests for the cointegrating rank of a VAR process
Saikkonen, Pentti; Lütkepohl, Helmut - 1997
Likelihood ratio (LR) tests for the cointegrating rank of a vector autoregressive (VAR) process have been developed under different assumptions regarding deterministic terms. For instance, nonzero mean terms and linear trends have been accounted for in some of the tests. In this paper we provide...

Problems related to bootstrapping impulse responses of autoregressive processes
Benkwitz, Alexander; Lütkepohl, Helmut; Neumann, Michael H. - 1997
Bootstrap confidence intervals for impulse responses computed from autoregressive processes are considered. A detailed analysis of the methods in current use shows that they are not very reliable in some cases. In particular, there are theoretical reasons for them to have actual coverage...

A parametric approach to the estimation of cointegration vectors in panel data
Breitung, Jörg - 2002
In this paper a parametric framework for stimation and inference in cointegrated panel data models is considered that is based on a cointegrated VAR(p) model. A convenient two-step estimator is uggested where in the first step all individual specific parameters are estimated, whereas in the...

Structural vector autoregressive models and monetary policy analysis
Holtemöller, Oliver - 2002
In this paper, the structural vector autoregressive (SVAR) model is used to analyze short-run and contemporaneous relationships between monetary aggregates and other macroeconomic variables. This requires imposing restrictions on the correlation structure of the VAR residuals. Different...
