摘要：In this study,econometric models were developed for profitibalities of farm enterprises. Three enterprises such as tobacco, cotton and wheat 'were taken into consideration. The independent variables involved in the models are specific costs which are expected to be : effective on the profitabilities, gross margins. Estimators were first obtained through least squares and then more efficient estimators were found through seemingly unrelated regression using cross ! sectional farm data. Al1 the estimators were interpreted and compared to each others.^.
