Título: ONE SIZE DOES NOT FIT ALL: EVALUATING THE IMPACT BETWEEN MICROENTERPRISE MEASUREMENT AND POLICY EVALUATION
Researchers and economic development practitioners regard microenter-prises (MEs) as pivotal actors for economic development, poverty alleviation, andjob creation. Notwithstanding the importance of MEs in the economy, there is noconsistent definition of MEs; and thus, there is no consensus on the appropriate mea-surement and criteria that should be used to evaluate microenterprise performance.Two of the most commonly accepted standards criteria to determine MEs are thenumber of employees and total annual revenues. Although there is a growing body ofresearch conducted on microenterprise performance using the employment criteria todetermine the firm size, fewer studies have used the revenue criteria. These criteriawill be compared in a regional activity model at different units of geographic scale(state, county, and census tract level) using data from US business. Results suggestthat there are no statistically significant changes in the estimated model when the cri-teria are changed for the same geographic unit of scale. However, for the same criteria(employment-based or revenue-based), a change in the unit of geographic aggrega-tion produces different and sometimes contradictory results. These results imply thatevaluations of MEs and their factors are more sensitive to scale than to criteria, raisingawareness that for proper program evaluation, the unit of data aggregation matters.
