Effects of aggregation error on analysis of agricultural production potential - Washington, D.C. (EUA) 1983 - 42 p. - Technical Bulletin (USDA) no. 1677 .

Tab.; 25 ref.; Sum. (En)

Agricultural economists involved in aggregate supply and demand analysis take one of two approaches: developing and then aggregating many micromodels; or directly estimating aggregate relationships. The micro approach is more costly and time consuming, although errors in specifying relationships and in measuring parameter values are generally lower than in macromodels. Unfortunately, error is always incurred when micro-relationships are aggregated. Errors resulting from aggregating soil inventory detail and the effects these errors have on linear programming analysis of agricultural production potentials are measured in this study. The tradeoffs between error levels, study costs, and user needs, and the implications for economist involved in designing research programs are discussed
