Question One: A. Suppose the relationship between consumption expenditures and household income of a representative sample of households in Ghana is specified as, Y, = Bi+ B2X, +8,, where i refers to household i, and i = 1, 2,.., n It is believed that while low income households have similar and less flexible consumption habits, high income households have rather flexible and varied consumption habits. The consumption pattern so described corresponds to a situation where at least one of the fundamental assumptions to the General Linear Regression Model is violated, (1). Identify that or those of the fundamental hypotheses that are systematically violated. (ii). Indicate the consequences of the violation of those fundamental hypotheses on the ordinary least squares estimation of the specified model. (iii). Suggest an alternative estimation approach which corrects for the identified violation. [Marks 50]
