Abstract

A structural change test and corresponding change estimator of an instrumental variable nature are proposed. The strengths of the approach lie in its ease of application and the strong test power. It does not suffer from critical value adjustments required by the CUSUM type tests and is unique in that it tests and measures the size of the break in one operation. The power of this test is compared to others in the literature, both algebraically and through simulations, with favourable results.
