This paper develops residual-based monitoring procedures for cointegrating polynomial regressions (CPRs), i.e., regression models including deterministic variables and integrated processes, as well as integer powers, of integrated processes as regressors. The regressors are allowed to be...

This is a simulation-based warning note for practitioners who use the MGLS unit root tests in the context of structural change using different selection lag length criteria. With T=100 , we find severe oversize problems when using some criteria, while other criteria produce an undersizing...

This paper studies long economic series to assess the long-lasting effects of pandemics. We analyze if periods that cover pandemics have a change in trend and persistence in growth, and in level and persistence in unemployment. We find that there is an upward trend in the persistence level of...

We consider the problem of testing for a structural break in the spatial lag parameter in a panel model (spatial autoregressive). We propose a likelihood ratio test of the null hypothesis of no break against the alternative hypothesis of a single break. The limiting distribution of the test is...

This article employs recently developed unknown structural break tests to investigate intrinsic structural instability in China inflation dynamics over 1981¨C2007. In order to capture accurately the statistical nature of potential structural beak, we use asymptotic p-value function under the...

Analysis on structural changes in macroeconomic data series has been the key issue for studying data quality. This paper studies the structural changes in China s 36 macroeconomic time series using joint estimation model, and we find out the characteristics and movement pattern for the outliers....
