According to an article in the NY Times yesterday:
[Alan ]Greenspan cautioned that the country should not be lulled into a false sense of security about the
federal deficit just because at the moment interest rates on long-term Treasury securities remain [fairly
constant].
1)
Draw diagrams below showing equilbrium in the markets for Foreign Exchange and Loanable Funds. Be
sure to label all axes and curves that you draw, and show the initial equilbrium exchange rate e0, interest
rate r0, savings LF0, and dollars exchanged for foreign currency FX0.
2)
If the government increases its deficit, which curve shifts?_________ Which direction?______ This shift
(ceteris paribus) should cause interest rates to (rise or fall) _________, the dollar to appreciate or depreciate)
________________, and the trade deficit to (rise or fall) __________
3)
Show the shift on your graphs below. Label the new equilibrium values e1, r1, LF1, and FX1.
4)
In fact, we have not seen the interest rate change mentioned above, which gives rise to the “false sense of
security” that Greenspan mentioned. A (rightward, leftward) __________ shift of the __________ curve
would explain the lack of movement in interest rates. On your graphs below, show this shift and label the
new equilibrium values e2, r2, LF2, and FX2.
5)
In recent years the Saudis, Chinese, and Indians have purchased increasing amounts of US Treasury bonds
and currency. If foreigners decide not to purchase US bonds and dollars anymore, and current US budget
deficit trends continue, the macromodels discussed in class would predict that US interest rates will (increase,
decrease, ?)______________, the dollar will (depreciate, appreciate, ?) ___________, US net exports will
(increase, decrease, ?),__________ US Investment will (increase, decrease, ?) _____________, US long term
real growth rates will (increase, decrease, ?)_______________, and your opportunity to become wealthy will
(increase, decrease, ?)_____________. If you like, you may (optionally) explain your answer below and on
the back of the page, to make sure I understand your reasoning.
