The island nation of Macadamia recently experienced an 800 percent jump in tourism, increasing income throughout the island.

What impact will the increase in income have on the equilibrium interest rate in Macadamia, assuming no change in the supply of money?

What will the Macadamia Central Bank have to do to keep the increase in income from impacting the interest rate?
