Type:ArticleAbstract:We give a brief introduction to the vector autoregressive model for cointegrated I(2) variables and show how some plausible economic relations can be formulated in the I(2) framework in such a way that likelihood ratio ...

- Macroeconomic Dynamics, 2003, 7, 5, 711-733
Type:ArticleAbstract:A small macroeconomic model is constructed to study the transmission of the monetary policy conducted by the Deutsche Bundesbank (DBB) since the middle of the 1970s. For this purpose, quarterly, seasonally unadjusted data ...
Title:Test Procedures for Unit Roots in Time Series with Level Shifts at Unknown Time Author(s):LANNE, Markku; LUETKEPOHL, Helmut; SAIKKONEN, PenttiDate:2003Citation:
- Oxford Bulletin of Economics and Statistics, 2003, 65, 1, 91-115.
Type:ArticleAbstract:Two types of unit root tests which accommodate a structural level shift at a known point in time are extended to the situation where the break date is unknown. It is shown that for any estimator for the break date the tests ...
Title:Uncovered Interest Rate Parity and the Expectations Hypothesis of the Term Structure: Empirical Results for the U.S. and Europe Author(s):BRUEGGEMANN, Ralf; LUETKEPOHL, HelmutDate:2005Citation:
- Applied Economics Quarterly, 2005, 51, 2, 143-154.
Type:ArticleAbstract:A system of U.S. and euro-area short and long-term interest rates is analyzed. According to the expectations hypothesis of the term structure, the interest rate spreads should be stationary and according to the uncovered ...
Title:Testing for a Unit Root in a Time Series with a Level Shift at Unknown Time Author(s):SAIKKONEN, Pentti; LUETKEPOHL, HelmutDate:2002Citation:
- Econometric Theory, 2002, 18, 2, 313-348.
Type:ArticleAbstract:Unit root tests for time series with level shifts of general form are considered when the timing of the shift is unknown. It is proposed to estimate the nuisance parameters of the data generation process including the shift ...
Title:Unit Root Tests for Time Series with Level Shifts: A Comparison of Different Proposals Author(s):LANNE, Markku; LUETKEPOHL, HelmutDate:2002Citation:
- Economics Letters, 2002, 75, 1, 109-114.
Type:ArticleAbstract:A number of unit root tests which accommodate a deterministic level shift at a known point in time are compared in a Monte Carlo study. The tests differ in the way they treat the deterministic term of the DGP. It turns out ...
Title:Comparison of Unit Root Tests for Time Series with Level Shifts Author(s):LANNE, Markku; LUETKEPOHL, Helmut; SAIKKONEN, PenttiDate:2002Citation:
- Journal of Time Series Analysis, 2003, 23, 6, 667-685.
Type:ArticleAbstract:Unit root tests are considered for time series which have a level shift at a known point in time. The shift can have a very general nonlinear form, and additional deterministic mean and trend terms are allowed for. Prior ...
