Finite Sample Properties of Impulse Response Intervals in SVECMs with Long-Run Identifying Restrictions

Brüggemann, Ralf

This paper investigates the finite sample properties of confidence intervals for structural vector error correction models (SVECMs) with long-run identifying restrictions on the impulse response functions. The simulation ...

Forecasting Euro-Area Variables with German Pre-EMU Data

Brüggemann, Ralf; Lütkepohl, Helmut; Marcellino, Massimiliano

It is investigated whether Euro-area variables can be forecast better based on synthetic time series for the pre-Euro period or by using just data from Germany for the pre-Euro period. Our forecast comparison is based on ...

On the Small Sample Properties of Weak ExogeneityTests in Cointegrated VAR models

Brüggemann, Ralf

We investigate the small sample properties of two types of weak exogeneity tests in cointegrated VAR models that are frequently used in applied work. The first one is the standard Likelihood Ratio (LR) test in the Johansen ...

Uncovered Interest Rate Parity and the Expectations Hypothesis of the Term Structure

Empirical Results for the U.S. and Europe

Brüggemann, Ralf; Lütkepohl, Helmut

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 ...
