摘要:
This paper outlines a methodology to test for structural break in a smooth time-varying cointegration model. We show how such a problem can be brought down to the standard procedure proposed by Hansen (J Bus Econ Stat 10:321-335, 1992). As an application, we investigate the long-run relationship between the crude oil price and the gasoline retail price for Switzerland.
