2.
For the given in Problem 1:
(a)
Write the equation of the saving function.
(b)
Draw a figure showing the equilibrium level
of national income in terms of desired saving and
investment.
3.
Starting from the given and figure of Problem 1,
and assuming that autonomous investment expen-
ditures increase from I
= 100 to I

= 200, draw
a figure in terms of total expenditures showing the
new equilibrium level of national income.
4.
Starting from the given and figure of Problem 2, and
assuming that autonomous investment expenditures
increase from I
= 100 to I

= 200:
(a)
Draw a figure in terms of desired saving and
investment showing the new equilibrium level of
national income.
(b)
