Q: Suppose the government increases its spending by $100 million, and the marginal propensity to consume (MPC) is 0.8. What is the total change in GDP according to the simple spending multiplier formula?

$$\frac{1}{1-0.8} = 5$$, so $$5 \times 100$$ million = $$500$$ million increase in GDP.

Question 16

Suppose the Taylor Rule is given by $$i = r^* + \pi + 0.5(\pi - \pi^*) + 0.5(y - y^*)$$, where $$i is $$the nominal interest rate, $$r^* is $$the equilibrium real interest rate, $$\pi is $$the current inflation rate, $$\pi^* is $$the target inflation rate, $$y is $$actual output, and $$y^* is $$potential output. If $$r^* = 2$$, $$\pi = 3$$, $$\pi^* = 2$$, $$y = y^*$$, what is the recommended nominal interest rate?

Accepted Answer

$$i = 2 + 3 + 0.5(3-2) + 0.5(0) = 2 + 3 + 0.5(1) = 5.5$$
