<br />. <br /> <br />o <br />-.l <br />i\,j <br />~ <br /> <br />. <br /> <br />given exogenously specified population and productivity <br /> <br /> <br />estimates, and aggregate production and utility functions; <br /> <br /> <br />2. The Data Resources Inc. interindustry energy model (3), <br /> <br /> <br />used to estimate the general economic output and price <br /> <br /> <br />structure and the interaction between energy and the <br /> <br /> <br />rest of the economy, given an aggregate consumer utility <br /> <br /> <br />function and nine sectoral interindustry production functions, <br /> <br /> <br />.all of which are estimated on the basis of past consumer and <br /> <br /> <br />producer behavioral relations. Aggregate consumption and <br /> <br /> <br />investment amounts are obtained from the growth model; <br /> <br />3. The Brookhaven National Laboratory and University of <br />Illinois input-output model (4), used to estimate <br />functional end use energy requirements (e.g. space heat <br />and motive power requirements) and detailed labor, capital, <br />and material requirements, given an exogenously specified <br /> <br />110-sector order vector of final demands and a 110 by 110 <br /> <br />-; <br /> <br />matrix of input-output coefficients, ~ggregates of which <br /> <br />". <br />are obtained from the DRI interindustry model. Detailed <br /> <br />energy into energy coefficient relations are obtained <br />from a minimum cost solution of a linear programming <br /> <br />allocation model of the energy system. <br /> <br />4. The Brookhaven National Laboratory linear programming <br />energy system allocation model (5), used to estimate <br />physical flows within the energy sector, and the associated <br /> <br />least-cost mix of energy supplies and covers ion activities, <br /> <br />given functional energy end use requirements from the <br />input-output model, prices from the DRI interindustry <br /> <br />model, and exogenously specified energy supply amounts <br /> <br />and/or supply price schedules. <br /> <br /> <br />As indicated, these models are defined at the national level and, <br /> <br /> <br />hence, none of the regional detail repr~sented in the FEA-PIES <br /> <br /> <br />based energy futures is contained in the ERDA Forecasts. <br /> <br />. <br /> <br />-,'," <br />>~"~:-~. <br /> <br />.~,~" <br /> <br />.,-.-;-"-'i"t--. <br /> <br />,.'_1,." <br /> <br />~- ")- <br />...... <br /> <br />"~!'
