ABSTRACT The REMI and IMPLAN models are widely used approaches to estimating economic impacts for small regions. However, few benchmarks exist for assessing these estimates. This paper evaluates the relative performance of these models in terms of a given impact: the opening of an automobile assembly plant in central Illinois. Although our results are not conclusive and are limited by our application, we find that in terms of several indirect performance criteria, IMPLAN's outcomes, on balance, are somewhat more plausible than those for REMI.
