Building on previous research this study utilizes static input-output analysis to estimate national income and foreign exchange impacts of hypothesized aluminum smelting in Jamaica and Guyana. Aluminum smelting is found to be consistent with very large increases in wages, operating surplus, and foreign exchange earnings. A domestic supply bottleneck in the public utilities sector, however, specifically electricity generation, is evident in both countries. It is also estimated that the vast majority of stimulated wages will be generated outside of the mining sector.
