9 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 e 0, interest rate r 0, savings LF 0, and dollars exchanged for foreign currency FX 0. 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 e 1, r 1, LF 1, and FX 1. 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 e 2, r 2, LF 2, and FX 2. 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.
