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 1-3 The table below lists the major items in a country’s Balance of Payments accounts. This country’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. The Current Account and the Financial Account CURRENT ACCOUNT   Billions of dollars Exports of Goods and Services 834 Imports of Goods and Services 499 Primary Income Received from Abroad 132 Primary Income Paid Abroad 38 Secondary Income Received from Abroad 35 Secondary Income Paid Abroad 76     FINANCIAL ACCOUNT   Billions of dollars Net acquisition of financial assets – 988 Net incurrence of liabilities + 639 Net change in financial derivatives – 29 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.   Calculate the Financial Account balance.

Chаpter 10 Fоrmulаs аnd Definitiоns All symbоls 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. ***************************** The U.S. dollar/British pound exchange rate is $2/£ (two dollars per one pound). A Big Mac costs $5 in New York City and £2 in London. The difference in the cost of the Big Mac is representative of the difference in the cost of living in the two cities. We can conclude that the pound is ________, and U.S. tourists will be ________.
