Minimum Requirements Approach

to the Economic Base


The minimum requirements approach (MRA) compares a focal region's employment pattern to that of similar(ly sized) regions. It assumes that regional employment in any specific industry (i) in that region (r) with the lowest (or close to the lowest) employment percentage in that industry is just sufficient to satisfy local demand and does not contribute to exports. This industry than does not include any basic employment. All other regions, including our focal region, would employ basic (export) workers in any specific industry to the extent that its exployment exceeds that industry's employment in the 'minimum requirement region'.
