Economists in Funlandia, a closed economy,
have collected the following information about
the economy for a particular year:
Y = 10,000
C = 6,000
T = 1,500
G = 1,700
The economists also estimate that the
investment function is:
I = 3,300 – 100 r,
where r is the country’s real interest rate,
expressed as a percentage. Calculate private
saving, public saving, national saving,
investment, and the equilibrium real interest
rate.
