This would have to be done on the basis of little, and as yet <br /> <br />uncompiled, data. <br /> <br />In such circumstances, it seemed preferable to omit <br /> <br />agglomeration and economy of scale effects from the model structure in the <br /> <br />recognition that such an omission probably leads to underestimates of the <br /> <br />overall impact of large scale EET development. <br /> <br />Numerous Exo~enous Inputs - Because of the highly disaggregated nature of <br /> <br />this model, there are a large number of inputs required to run it. While this <br /> <br />is primarily a data and resources problem from the point of view of the mode 1 <br /> <br />operator, it also impinges upon the user in the sense that errors in the <br /> <br />input, no matter how accurate the model, will be transformed into errors in <br /> <br />output. The nature and scale of this study did not provide the resources for <br /> <br />a detailed estimate of inputs for all sectors, but only those which were most <br /> <br />closely associated with the objectives of the study. <br /> <br />In a comparative <br /> <br />analysis among results for the year 2000 under different scenarios, however, <br /> <br />crude est:Unates of sector final <br /> <br />~~~) <br />~l ~ - the results, only <br /> <br />demand do not affect, for the most part, <br /> <br />the <br /> <br />the absolute magnitudes of these results. <br /> <br />Capital Formation - The economic impact of capital formation is embodied <br /> <br />in the final demands and rest-of-the-world payments of the input-output <br /> <br />sectors of the model. The final demands reflect the capital formation called <br /> <br />forth from local sectors of the economy to provide Basin replacement capacity <br /> <br />in long-run economic equilibrium- <br /> <br />The payments to the rest-of-the-world <br /> <br />reflect, in part, the continuous repayment of debts incurred as a result of <br /> <br />capital formation. This characterization of capital accounts, while accurate <br /> <br />in an equilibrium context, does not capture the time-dependent economic impact <br /> <br />of large and perhaps transient bursts of plant construction necessary to <br />
