Estimated characteristic roots in stationary auto-regressions are shown to give rather noisy information about their population equivalents. This is remarkable given the central role of the characteristic roots in the theory of autoregressive processes. In the asymptotic analysis the problems...

We characterize the restrictions imposed by the minimal I(2)-to-I(1) transformation that underlies much applied work, e.g. on money demand relationships or open-economy pricing relationships. The relationship between the parameters of the original I(2) vector autoregression, including the...

The long-run and short-run structure of the Danish manufacturing export sector is analyzed within a cointegrated vector autoregressive model. The price variables of the analysis can be characterized as integrated of second order, I(2), but long-run homogeneity seems to cancel the I(2)-trend...

This paper presents likelihood analysis of the I(2) cointegrated vector autoregression with piecewise linear deterministic terms. Limiting behavior of the maximum likelihood estimators are derived, which is used to further derive the limiting distribution of the likelihood ratio statistic for...

The effects of innovational outliers and additive outliers in cointegrated vector autoregressive models are examined and it is analyzed how outliers can be modelled with dummy variables. A Monte Carlo simulation illustrates that additive outliers are more distortionary than innovational...

This comment discusses the presence of Phillips-curve effects for the UK, 1860-2004. A reconsideration of the empirical evidence in Castle and Hendry (2009) seems to suggest different functional relationships between wage inflation and unemployment for different periods. We conclude that the...

This paper performs a multivariate cointegration analysis of UK money demand 1873–2001, and illustrates how a long-run time series analysis may be conducted on a data set characterized by turbulent episodes and institutional changes. We suggest accounting for the effects of the two world wars...

Relationships between the Federal funds rate, unemployment, inflation and the long-term bond rate are investigated with cointegration techniques. We find a stable long-term relationship between the Federal funds rate, unemployment and the bond rate. This relationship is interpretable as a policy...
