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 savings?
Based on Abel, Bernanke and Croushore, 10th edition, Chapter 4, Numerical Problems No. 1.
A consumer is making saving plans for this year and next. She knows her real income after
taxes will be $50,000 in both years. Any part of her income saved this year will earn a real
interest rate of 10% between this year and next year. Currently, the consumer has no wealth
(no money in the bank or other financial assets, and no debts). There is no uncertainty about
the future.
a) Formally derive the consumer’s intertemporal budget constraint.
b) Using the given numerical values rewrite and graph the budget line.
c) Find the consumer’s PVLR.
The consumer wants to save an amount this year that will allow her to (1) make college tuition
payments next year equal to $16,800 in real terms; (2) enjoy exactly the same amount of
consumption this year and next year, not counting tuition payments as part of next year’s
consumption; and (3) have neither assets nor debts at the end of next year.
