Chapter 9 Formulas and Definitions All symbols are as in the textbook and lectures. CA + FA = 0, ignoring KA, and except for the statistical discrepancy GDP = C + I + G + X – M GNP = GDP + net primary income + net secondary income GNP = C + I + G + CA S + (T – G) = I + CA ********************************* Information for questions 8-9 Consider the following hypothetical information on the National Income and Product Accounts for Indonesia. Indonesia’s Capital Account is 0. The amounts are in billions of dollars, but ignore the “billions” part, that is, just treat the numbers as whole numbers in dollars. For all questions, enter a whole number of the appropriate sign. Enter 0 if the answer cannot be obtained with the information given. Only exact answer is accepted, so double check your calculations. The answers may be positive or negative, make sure to enter the right sign. Calculate Indonesia’s public savings.

Chapter 10 Formulas and Definitions All symbols are as in the textbook and lectures. Unless otherwise stated, you can assume that two countries have purchasing power parity (PPP) and interest rate parity. Exchange rate when there is PPP: R = P / P*. In this formula, P and P* can be regarded as prices of individual goods or of consumption baskets. Approximate relationship when there is interest rate parity: i – i* = (F – R)/R. For the purpose of this test, take this equation to be exact, not approximate. You can also use the equivalent equation i – i* = F/R – 1. For this formula to work, i and i* must be fractional, not percentages. So, a domestic interest rate of 1.34% is written i=1.0134, a foreign interest rate of 22.5% is written i*=1.225. Note that you may be asked to enter answers as percentages, though. ***************************** Information for questions 13-15 The figure represents possible supply and demand curves for the Brazilian Real (symbol R). The vertical axis is in the usual unit of U.S. dollars per Real. Note that one vertical grid spacing is 1 cent. Initially the Real is trading with supply curve S0 and demand curve D0, therefore the initial exchange rate is 0.13 $ / R. For numeric questions, only the exact answer is accepted, so double check that you are reading the graph correctly. All graphical answers can be made exact with the assumption: if two curves seem to cross where two grid lines also cross, then they do. Beginning from the initial situation (with supply S0 and demand D0), suppose that the International Olympic Committee selects Rio de Janeiro for the next Summer Olympic Games. This causes a rise in the demand by Americans for hotel rooms and other goods and services in Brazil, which of course need to be paid in Brazilian reais. All else equal this causes the curve of the Real to shift to the .
