Non-linear cointegrating regression: Theory and Applications


This project will develop estimation and inference theory in non-linear cointegrating regression.  Empirical applications in money demand, trading data and various real time series data will also be considered.

Program Type



Using the fundamental advances raised in the past decade, we will explore non-linear regression models with non-stationary time series.  The main targets will be threshold effects in linear and non linear cointegrating regression, testing for non linear cointergration and model checks in non linear cointergrating regression.

The aim is to develop parametric and non parametric methods so that they are comparable to those appearing in linear cointegrating regression.  We will adopt some conventional estimators in the development of our asymptotic theory.  This will lead to a major simplification in the context of non linear cointegrating regression and structural non linear functional regression, and open up new possiblity for empirical research.
