The concept of melding together two separate models to arrange the most complete economic picture possible is analyzed in this 1980 report. The MIO and MEPA models were brought together for a project evaluating the economic effects of container-port expansion at the Massachusetts Port Authority. Researchers were able to perform a policy simulation that used both detailed inter-industry relationships and well specified econometric structural equations by conjoining the MEPA and MIO models. The results showed potentially substantial gains in wages, personal income, and state government revenues, but only modest increases in employment gains per ten million dollars of investment in port facility construction.
