Webstructural breaks. In doing so we discuss the distinction between taking structural break dates as exogenously determined, an approach initially adopted in the literature, and endogenously testing break dates. That is, we differentiate between testing for breaks when the break date is known and when it is assumed to be unknown. Also WebIt tests the null hypothesis that there is no structural break against the alternative that there is a known structural break at time T b.
