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. CONSUMPTION (Bions of dollars) ) 700 600 500 400 300 200 100 0 -100 9 100 200 300 400 500 000 DISPOSABLE INCOME (Billions of dollars) 700 000 From the preceding data, you know that the level of savings in the economy last year was 3 economy is billion and the marginal propensity to save in this Suppose that this year, disposable income is projected to be $600 billion. Based on your analysis, you would expect consumption to be 3 billion and savings to be S billion,

a=$250b, I=$500b, G= $350b, MPC=80%; Calculate: the multiplier the equilibrium level of income the equilibrium level of consumption the equilibrium level of saving  Now assume that individuals in the aggregate would like to save more.  Write a new consumption function that reflects this change. What is your new assumption?
