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...

This paper introduces tests for residual serial correlation in cointegrating regressions. The tests are devised in the frequency domain by using the spectral measure estimates. The asymptotic distributions of the tests are derived and test consistency is established. The asymptotic distributions...

The author develops tests for a unit root based on the Durbin-Hausman principle. The ordinary least squares estimator and the pseudo instrumental variables estimator using the current variable as an instrument are employed to formulate test statistics. The limit distributions of these tests are...

C. R. Nelson and C. I. Plosser (1982), in a classic paper, failed to find strong evidence against the null hypothesis of a generating process with a unit autoregressive root for thirteen U.S. macroeconomic time series. P. Perron (1989) claimed that such evidence was available for a majority of...
