Use both numerical and graphical methods to find the multiplier effect of the following shift in the consumption function in an economy in which investment is always $220, government purchases are always $100, and net exports are always 2-40. (Hint: What is the marginal propensity to consume?)
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.

Suppose now that Kejimkujik’s national income increases to $330 billion. Assuming the amount paid in taxes is fixed at $100 billion and that MPC = 0.6, what is the new amount of household consumption?

$219.4 billion
$220.6 billion

Consider a hypothetical economy in which the marginal propensity to consume (MPC) is 0.50. That is, if disposable income increases by $1,
consumption increases by 50c.
Suppose further that last year disposable income in the economy was $400 billion and consumption was $350 billion.
On the following graph, use the blue line (arcle symbol) to pict this economy's consumption function based on these data.
