In this paper we develop a test of the joint null hypothesis of parameter stability and a unit root within an ADF style autoregressive specification whose entire parameter structure is potentially subject to a structural break at an unknown time period. The maintained underlying null model is a...

Results for the identification of non-linear models are used to support the traditional form of the order condition by sufficient conditions. The sufficient conditions reveal a two step procedure for firstly checking generic identification and then testing identifiability. This approach can be...

For policy makers and business cycles analysts is important to count on variables that anticipate points of inflection in economic activity. This paper studies aggregate real money balances as leader indicator of the economic activity based on a Probit mo

This paper derives the memory of the product series xtyt, where xt and yt are stationary long memory time series of orders dx and dy, respectively. Special attention is paid to the case of squared series and products of series driven by a common stochastic factor. It is found that the memory of...

Our paper reports on Monte Carlo experiments using Evans's data-generating process to gauge the performance of these two kinds of regime-switching tests.
