Abstract :Testing for structural change or the Chow Test enjoyed numerous applications since its introduction by Chow. There have also been several extentions of this test. One of the more re- cent extentions is to the case of structures with unequal disturbance variances. This paper ex- tends the computationally sîmple Lagrange Multiplier test of structural change under hetero- scedasticity introduced by Erlat to the case of several structures. The result is then used in testing the Life-Cycle Hypothesis of saving utilizing household expenditure survey data of Ankara.
