Imagine this economy has a 10% tax on income. The following are exogenous (not directly affected by income): G = 11 I = 4 X = M = 0 The consumption function is: C = k + cY, where k = 3, c = 0.8 Now we have to take that tax into account. Here is a way to think about it: Look at the consumption function. It says if you give me one more dollar of income I will spend 80 cents of it (mpc = 0.8). BUT I can only spend what I receive. I can only spend my after-tax or disposable income. With a 10% tax, I don't receive Y I receive 90% of Y or Y*(1-t) where t = 10% or 0.1. Let's define disposable income as Yd where Yd = Y*(1-t). Therefore we restate our consumption function as C = k + cYd Now we have, in this case, C = k + cYd or C = 3 + 0.8Yd or C = 3 + 0.8*(Y*[1-0.1]) or C = 3 + 0.72Y. Now what is the equilibrium GDP? Give the answer to ONE decimal place.

Consider the hypothetical country of Kejimkujik. Suppose that national income in Kejimkujik is $300 billion, households pay $100 billion in taxes, household consumption is equal to $160 billion, and the marginal propensity to consume (MPC) is 0.6. On the following graph, use the blue line (circle symbol) to plot the economy's consumption function.
