A consortium of energy companies plans to invest £320 £320\,£320 million in a new deep-water wind turbine assembly hub in the Humber region. An economic impact assessment estimates that in this regional economy, the marginal propensity to save (MPSMPSMPS) is 0.12, the marginal propensity to tax (MPTMPTMPT) is 0.15, and the marginal propensity to import (MPMMPMMPM) is 0.13. Assuming other things remain equal, what will be the total increase in national income (GDP) resulting from this investment?
