In applied time series analysis, checking for autocorrelation in a fitted model is a routine diagnostic tool. Therefore it is useful to know the asymptotic and small sample properties of the standard tests for the case when some of the variables are cointegrated. The properties of residual...

A test for the cointegrating rank of a vector autoregressive (VAR) process with a possible shift and broken linear trend is proposed. The break point is assumed to be known. The setup is a VAR process for cointegrated variables. The tests are not likelihood ratio tests but the deterministic...

Using business survey data on German manufacturing firms, this paper provides tests for hypotheses that predict distributrional effects in the transmission mechanism of monetary policy. Effects of monetary policy shocks on the business conditions of firms of several size classes are analysed,...

We investigate autoregressive approximations of multiple frequency I(1) processes, of which I(1) processes are a special class. The underlying data generating process is assumed to allow for an infinite order autoregressive representation where the coefficients of the Wold representation of the...

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 interest rate parity the difference between the U.S. and euro area longterm...

Different identification schemes for monetary policy shocks have been proposed in the literature. They typically specify just-identifying restrictions in a standard structural vector autoregressive (SVAR) framework. Thus, in this framework the different schemes cannot be checked against the data...

Using a small VAR of the current account and investment, we identify two categories of shocks: permanent vs. transitory and country-specific vs. global. Our approach involves only the most minimal identifying assumption. Using data from the G7n countries, we find that the predictions of the...

A multivariate structural time series model is applied to the factor inputs of a production function to estimate the Belgian output gap. The number of independent cycles and the frequencies are not restricted a priori. Phase shifts are introduced to allow for leads and lags. Over 1983-2004, a...

We investigate the controversial issue whether unemployment is related to productivity growth in the long run, using U.S. data in a framework of infrequent mean shifts. Tests find (endogenously dated) shifts around 1974, 1986, and 1996, system techniques indicate that the shifts are common...
