Question
Use the Keynesian Model to answer this set of questions.
Suppose that in the economy under consideration the consumption function can be
written as C=200+.8(Y-T). Furthermore, you know that taxes are autonomous and
equal to $10.
Now, suppose that investment spending is equal to $50 at every level of disposable
income and government spending is constant and equal to $100 at every level of
disposable income, suppose that (X-M) is constant and equal to $20 at every level of
disposable income.
(a)Draw a graph of the consumption function with respect to disposable income.
Measure/show consumption spending on the vertical axis and disposable income on the
horizontal axis
(b) Calculate equilibrium national income Y, from the information given.
(c) From the information given above is the government running a deficit or surplus
budget? Explain why.
(d) Full employment output in this economy (Y) is equal to $2000 what do you predict is
happening to inventories if the full employment level of output is produced? Hint: to
answer this question you will need to compare this full employment level of output with
the level of output.
(e) Show Y. from (b) and Yr from (d) on one Keynesian 45° diagram. What gap is present
in the economy?
(f) If the government wants to attain full employment income (Y.) by how much would
government spending have to increase given the information from beginning?
