<br />o <br />c.", <br />W <br />,-,' <br /> <br />The methodology employed to make these estimates was quite involved and <br /> <br />determined in large measure by the data which were readily available. The <br /> <br />primary data sources were Udis, Howe and Krieder, Morris (1976), and LASL. <br /> <br />Initially, 1970 and 1980 TGO estimates were compiled for each sector using <br /> <br />Udis, Howe and Krieder as the principle source of 1970 TGO estimates and <br /> <br />Morris as the principle source for the 1980 TGO estimates~ although some <br /> <br />independent estimates based upon recent observations were also used. These <br /> <br />values were then used in conjunction with the price adjusted 1980 input-output <br /> <br />coefficients to estimate a vector of final demands for 1970 and 1980. A <br /> <br />simple mean of these two values was then used to estimate 1975 final demands. <br /> <br />@) <br /> <br />/ <br /> <br />These final demands were also modified in the light of final demand estimates <br /> <br />made in Udis, Howe and Kriederj Morris;....:r' LASL; - wdependent estimates of / <br /> <br />final demand for those sectors whose final demand was a readily distin- <br /> <br />guishable portion of sales; and judgement as the possibilities for substi- <br /> <br />tuting local product markets for export markets. <br /> <br />The modified vector of 1975 sector final demands ",as then used in the <br /> <br />model to generate a ne'" vector of 1975 TGO. These t"'o vectors were thus made <br /> <br />consistent with each other and the Basin IS economic interrelationships as <br /> <br />characterized by the model. While this method of estimating the 1975 levels <br /> <br />of economic activity in the regions of the Basin is not entirely satisfactory <br /> <br />on either theoretical or empirical grounds, it does make good use of the <br /> <br />available information embodied in past estimates and takes into consideration <br /> <br />the relative importance of final demand and output as "drivers" in the various <br /> <br />sectors. It should also be noted that special care was taken to improve the <br /> <br />accuracy of FD and TGO in the energy and agricultural sectors in this report. <br /> <br />The preceding procedure was carried out in 1970 dollar values. The 1978 <br /> <br />dollar values of estimated 1975 FD and TGO (see Tables 2.4 and 2.5) ",ere <br />
