In this paper we propose tests for hypotheses regarding the parameters of the deterministictrend function of a univariate time series. The tests do not require knowledge of the form ofserial correlation in the data and they are robust to strong serial correlation. The data cancontain a unit root...

This paper shows that the integrated modified OLS (IM-OLS) estimator developed for cointegrating linear regressions in Vogelsang and Wagner (2014a) can be straightforwardly extended to cointegrating multivariate polynomial regressions. These are regression models that include as explanatory...

This paper addresses tests for structural change in a weakly dependent time series regression. The cases of full structural change and partial structural change are considered. Heteroskedasticity-autocorrelation (HAC) robust Wald tests based on nonparametric covariance matrix estimators are...
