These ‘sensitivities’ are empirical questions that are hotly disputed. 18.1 FISCAL VERSUS MONETARY POLICYIn this figure, when the money supply increases from $1 trillion to $1.2 trillion, the interest rate falls from 6 percent to 4 percent a year and investment increases from $2 trillion to $4 trillion.18.1 FISCAL VERSUS MONETARY POLICYHere, the same change in the money supply lowers the interest rate from 6 percent to 5 percent a year and increases investment from $2 trillion to $2.25 trillion.Monetary policy is less powerful here than in the previous case.
