- External borrowings and assistance
- Components:
- Current Account: Records trade in goods and services and transfer payments.
Key Concepts
- Nominal Exchange Rate: The number of units of domestic currency needed to purchase one unit of foreign currency.
- Real Exchange Rate: The relative price of foreign goods in terms of domestic goods.
- Devaluation vs. Depreciation:
- Devaluation: Decrease in the price of domestic currency under pegged exchange rates.
- Depreciation: Decrease in the price of domestic currency under floating exchange rates.
Important Formulas
- Current Account Balance: Trade Balance + Net Invisibles
- Trade Balance: Exports - Imports
- Capital Account Balance: Sum of all capital inflows - Sum of all capital outflows
Example of Balance of Payments for India (in million USD)
| Item | Million USD |
|---|---|
| Exports (of goods only) | 150 |
| Imports (of goods only) | 240 |
| Trade Balance | -90 |
| (Net) Invisibles | 52 |
| Current Account Balance | -38 |
| Capital Account Balance | 41.15 |
Economic Agents
- Definition: Individuals or institutions that take economic decisions.
- Types: Households, firms, government.
Fiscal Policy
- Definition: Government policy regarding spending and taxation.
- Components: Government expenditure, tax structure.
Exchange Rate Determination
- Under a flexible exchange rate regime, the exchange rate is determined by market forces without central bank intervention.

A.
Foreign Direct Investments (FDIs)
B.
Trade in goods and services
C.
External borrowings
D.
Portfolio investments
Correct Answer: B
Solution:
The current account includes trade in goods and services, as well as transfer payments.
Chapter Concept:
Balance of Payments (BOP)
A.
An increase in foreign direct investment (FDI) into the country.
B.
A decrease in exports of goods and services.
C.
A rise in remittances received from citizens working abroad.
D.
An increase in the country's external debt repayments.
Correct Answer: A
Solution:
A surplus in the capital account occurs when capital inflows exceed capital outflows. An increase in foreign direct investment (FDI) into the country represents a capital inflow, thus contributing to a surplus in the capital account.
Chapter Concept:
Balance of Payments (BOP)
A.
The exchange rate should remain unchanged.
B.
The exchange rate should decrease, making the dollar cheaper.
C.
The exchange rate should increase, making the rupee cheaper.
D.
The exchange rate should adjust to reflect the price differences, with the dollar depreciating.
Correct Answer: D
Solution:
According to the purchasing power parity theory, the exchange rate should adjust to reflect differences in price levels between countries. If US prices rise more than Indian prices, the dollar would depreciate relative to the rupee.
Chapter Concept:
Open Economy Macroeconomics
A.
Exchange rates should adjust to equalize the price of identical goods in different countries.
B.
Exchange rates should remain constant regardless of price levels.
C.
Exchange rates should be determined by government intervention.
D.
Exchange rates should be based on the gold standard.
Correct Answer: A
Solution:
The PPP theory suggests that in the long run, exchange rates should adjust to equalize the price of identical goods in different countries, accounting for differences in price levels.
Chapter Concept:
Purchasing Power Parity (PPP)
A.
Rs 40 per dollar
B.
Rs 50 per dollar
C.
Rs 60 per dollar
D.
Rs 70 per dollar
Correct Answer: B
Solution:
For PPP to hold, the exchange rate should equalize the price of the shirt in both countries. Therefore, $8 should equal Rs 400, implying an exchange rate of Rs 50 per dollar.
Chapter Concept:
Purchasing Power Parity (PPP)
A.
Fixed Exchange Rate
B.
Flexible Exchange Rate
C.
Managed Floating Exchange Rate
D.
Gold Standard
Correct Answer: C
Solution:
A managed floating exchange rate system, also known as dirty floating, combines elements of both fixed and flexible exchange rate systems, where central banks intervene to moderate exchange rate movements.
Chapter Concept:
Exchange Rate Determination
A.
It requires constant intervention by the central bank to maintain exchange rates.
B.
It automatically adjusts to correct surpluses and deficits in the balance of payments.
C.
It fixes the exchange rate at a predetermined level.
D.
It prevents any speculative attacks on the currency.
Correct Answer: B
Solution:
In a flexible exchange rate system, the exchange rate is determined by market forces, which helps automatically adjust for surpluses and deficits in the balance of payments.
