We consider a lag-augmented two- or three-stage least squares estimator for a structural dynamic model of nonstationary and possibly cointegrated variables without the prior knowledge of unit roots or rank of cointegration. We show that the conventional two- and three-stage least squares...

We consider the estimation of a structural vector autoregressive model of nonstationary and possibly cointegrated variables without the prior knowledge of unit roots or rank of cointegration. We propose two modified two stage least squares estimators that are consistent and have limiting...

This paper tries to answer the following basic question: have the high interest rates had the desired effect of appreciating the nominal exchange rates in the Asian crisis countries? We use Korean high-frequency (weekly) data during the crisis and its aftermath to examine the relationship...
