3. Answer the following questions about external wealth.
a. Home has external wealth of $100 million in period t. In t+1, Home purchases $160
million foreign assets, and Foreign purchases $120 million in Home assets. Assume a
world interest rate of 10% per annum. Compute the "change" in external wealth at t+1 for
Home.
b. A country's external wealth was -$1.5 billion at the end of 2015, and its trade balance
was $750 million in 2016. Assume the world interest rate is 5% per annum. What is the
"value" of a country's external wealth at the end of 2016?
1. The table below shows a country's hypothetical national income and product accounts data.

a. Compute the following accounts using the information in the table:
Gross national expenditure (GNE)
. Trade balance (TB)
•
Gross domestic product (GDP)
•
Gross national income (GNI)
.
Gross national disposable income (GNDI)
Current account (CA)
b. Derive the current account identity using the national income identity. Are savings greater
than or smaller than investment in this country? The national income identity is:
GNDIGNE + CA, GNE = C + G + I.
4. Assume that a country produces an output Q of 50 every year. The world interest rate is 10%.
Consumption C is 50 every year, and I = G = 0. There is an unexpected drop in output in year
0, so output falls to 28 and is then expected to return to 50 in every future year. If the country
desires to smooth consumption, how much should it borrow in period 0? What will the new
level of consumption be from then on?

- 2. Show how each of the following would affect the following US balance of payments: trade balance (TB), net factor income abroad (NFIA), net unilateral transfers (NUT), financial account (FA), and capital account (KA). Identify which specific account is affected in each case (e.g., +$10 in TB). Note that the sum of the balance of payment accounts is zero. Example: A California computer manufacturer purchases a $50 hard disk from a Malaysian company, paying the funds from a bank account in Malaysia. Answer: The US imports a hard disk from Malaysia: TB = $50 The US draws a foreign asset to pay for the import (less external asset): FA = +$50. (Note: The balance of payment identity holds: CA + FA (+KA) = −- $50 + $50 = 0. No KA in this example.) a. A US tourist in Japan sells his iPod to a local resident for yen worth $100.
