Q1Questions
Differentiate between balance of trade and current account balance.
Solution
The main differences between the Balance of Trade (BoT) and the Current Account Balance are as follows:
-
Scope: The Balance of Trade is a narrow concept. It only includes the transactions related to the export and import of goods (visible items). The Current Account is a much broader concept. It includes the Balance of Trade, as well as the balance of services (invisible items like shipping, banking, tourism) and transfer payments (gifts, remittances, grants).
-
Component: The Balance of Trade is a component of the Current Account. The Current Account Balance is calculated as the sum of the Balance of Trade and the Balance on Invisibles (net services + net transfers).
-
Indicator: The BoT indicates whether a country's exports of goods are greater than its imports of goods. The Current Account Balance provides a more comprehensive picture of a country's international transactions, showing whether the country is a net lender to (in case of a surplus) or a net borrower from (in case of a deficit) the rest of the world.
Q2Questions
What are official reserve transactions? Explain their importance in the balance of payments.
Solution
Official reserve transactions refer to the purchase or sale of foreign currencies by the central bank of a country from its foreign exchange reserves.
Their importance in the balance of payments (BoP) is that they are the ultimate financing items that bring the BoP account into balance. The BoP is said to be in surplus if autonomous receipts are greater than autonomous payments, and in deficit if autonomous payments are greater than autonomous receipts.
-
In case of a BoP deficit: The central bank will sell foreign exchange from its reserves to meet the excess demand. This is recorded as a positive item in the BoP account and is called an official reserve sale. The decrease in official reserves equals the overall BoP deficit.
-
In case of a BoP surplus: The central bank will buy the excess foreign exchange, leading to an increase in its official reserves. This is recorded as a negative item in the BoP account.
Therefore, official reserve transactions are the accommodating transactions that bridge the gap in the balance of payments. They are particularly important under a fixed or managed floating exchange rate system where the central bank has to intervene to maintain the exchange rate.
Q3Questions
Distinguish between the nominal exchange rate and the real exchange rate. If you were to decide whether to buy domestic goods or foreign goods, which rate would be more relevant? Explain.
Solution
The distinction between the nominal exchange rate and the real exchange rate is as follows:
-
Nominal Exchange Rate: This is the price of one currency in terms of another. For example, if it takes Rs. 80 to buy 1 US dollar, the nominal exchange rate is Rs. 80 per dollar. It tells us how many units of the domestic currency are needed to acquire one unit of a foreign currency, but it does not account for the price levels in the two countries.
-
Real Exchange Rate: This is the relative price of foreign goods in terms of domestic goods. It measures the rate at which goods of one country can be traded for the goods of another country. It is calculated by adjusting the nominal exchange rate for the price levels in the two countries.
Relevance for Purchasing Decisions:
The real exchange rate would be more relevant for deciding whether to buy domestic or foreign goods.
Explanation: The nominal exchange rate only tells you the price of currency. However, the decision to buy a good from a particular country depends on its actual cost. The real exchange rate provides this information because it compares the prices of goods. For instance, even if the domestic currency is strong (low nominal exchange rate), if inflation in the domestic country is very high, its goods might still be more expensive than foreign goods. The real exchange rate captures both the currency value and the price levels, giving a true picture of the relative cost and purchasing power. A higher real exchange rate makes foreign goods relatively more expensive, encouraging the consumption of domestic goods.
Q4Questions
Suppose it takes 1.25 yen to buy a rupee, and the price level in Japan is 3 and the price level in India is 1.2 . Calculate the real exchange rate between India and Japan (the price of Japanese goods in terms of Indian goods). (Hint: First find out the nominal exchange rate as a price of yen in rupees).
Solution
To calculate the real exchange rate, we first need to determine the nominal exchange rate and then use the price levels of both countries.
Step 1: Find the nominal exchange rate (e)
The nominal exchange rate should be expressed as the price of the foreign currency (Yen) in terms of the domestic currency (Rupees).
We are given: 1.25 Yen = 1 Rupee
Therefore, 1 Yen = 1 / 1.25 Rupees
So, the nominal exchange rate (e) = 0.80 Rupees per Yen.
Step 2: Identify the price levels
- Price level in Japan (Foreign Price, P_f) = 3
- Price level in India (Domestic Price, P_d) = 1.2
Step 3: Calculate the Real Exchange Rate (RER)
The real exchange rate is the relative price of foreign goods in terms of domestic goods. The formula is:
RER = (e × P_f) / P_d
Substituting the values:
RER = (0.80 × 3) / 1.2
RER = 2.4 / 1.2
RER = 2
Conclusion:
The real exchange rate is 2. This means that one unit of a Japanese good can be exchanged for two units of an Indian good. Japanese goods are twice as expensive as Indian goods.
Q5Questions
Explain the automatic mechanism by which BoP equilibrium was achieved under the gold standard.
Solution
Under the gold standard, each country defined the value of its currency in terms of a fixed amount of gold. This created a system of fixed exchange rates. The automatic mechanism for achieving Balance of Payments (BoP) equilibrium under this system is known as the price-specie-flow mechanism.
The process worked as follows:
-
Country with a BoP Deficit: A country with a BoP deficit (imports > exports) would have to pay for its excess imports in gold. This resulted in an outflow of gold from the deficit country.
- The outflow of gold would reduce the country's money supply, as the money supply was directly tied to its gold reserves.
- A reduction in the money supply would lead to a fall in the general price level (deflation).
- Lower domestic prices would make the country's goods cheaper for foreigners, leading to an increase in exports. Simultaneously, foreign goods would become relatively more expensive for domestic residents, leading to a decrease in imports.
- This increase in exports and decrease in imports would automatically correct the BoP deficit and restore equilibrium.
-
Country with a BoP Surplus: A country with a BoP surplus (exports > imports) would receive gold as payment.
- The inflow of gold would increase the country's money supply.
- An increase in the money supply would cause the general price level to rise (inflation).
- Higher domestic prices would make the country's exports more expensive and less competitive, leading to a fall in exports. Imports would become relatively cheaper, leading to an increase in imports.
- This fall in exports and rise in imports would eliminate the BoP surplus, restoring equilibrium.
In this way, the flow of gold between countries automatically adjusted price levels and trade flows to maintain BoP equilibrium without direct government intervention.
Q6Questions
How is the exchange rate determined under a flexible exchange rate regime?
Solution
Under a flexible exchange rate regime, also known as a floating exchange rate regime, the exchange rate is determined purely by the market forces of demand for and supply of foreign exchange. The central bank does not intervene in the foreign exchange market to influence the rate.
-
Demand for Foreign Exchange: People and firms demand foreign currency for various reasons, such as importing goods and services, sending gifts abroad, or purchasing financial assets in other countries. The demand curve for foreign exchange is downward sloping because a higher exchange rate (making foreign currency more expensive) increases the cost of foreign goods, which reduces the demand for imports and thus the demand for foreign currency.
-
Supply of Foreign Exchange: The supply of foreign currency comes from sources like exports of goods and services, receiving gifts or remittances from abroad, and foreign investment in the domestic country. The supply curve for foreign exchange is typically upward sloping because a higher exchange rate means foreigners can get more domestic currency for their currency, making domestic goods cheaper for them. This encourages exports, thus increasing the supply of foreign currency.
-
Equilibrium Exchange Rate: The equilibrium exchange rate is established at the point where the demand curve for foreign exchange intersects the supply curve. At this rate, the quantity of foreign currency demanded equals the quantity supplied. If the demand for foreign currency increases, the demand curve shifts to the right, leading to a depreciation of the domestic currency (a higher exchange rate). Conversely, if the supply of foreign currency increases, the supply curve shifts to the right, leading to an appreciation of the domestic currency (a lower exchange rate).
Q7Questions
Differentiate between devaluation and depreciation.
Solution
Both devaluation and depreciation refer to a decrease in the value of a country's currency relative to other currencies, but they occur under different exchange rate systems.
The key differences are:
| Basis | Depreciation | Devaluation |
|---|---|---|
| Exchange Rate System | Occurs under a flexible (or floating) exchange rate system. | Occurs under a fixed exchange rate system. |
| Cause | It is caused by market forces, i.e., an increase in demand or a decrease in supply of foreign currency in the foreign exchange market. | It is a deliberate, official action taken by a country's government or central bank to lower the currency's value. |
| Mechanism | It is an automatic market-driven adjustment. | It is a conscious policy decision announced by the monetary authority. |
| Example | If the exchange rate for the US dollar changes from Rs. 75 to Rs. 80 due to market dynamics, the rupee has depreciated. | If the government officially announces a change in the fixed exchange rate from Rs. 50 per dollar to Rs. 60 per dollar, it is a devaluation of the rupee. |
Q8Questions
Would the central bank need to intervene in a managed floating system? Explain why.
Solution
Yes, the central bank would need to intervene in a managed floating system.
Explanation:
A managed floating exchange rate system, also known as a 'dirty float', is a hybrid of the fixed and flexible exchange rate systems. Under this system:
-
The 'Float' Part: The exchange rate is primarily determined by market forces of demand and supply, allowing it to fluctuate.
-
The 'Managed' Part: The central bank does not let the exchange rate float freely without any limits. It actively intervenes in the foreign exchange market by buying or selling foreign currencies to influence the exchange rate.
The reason for this intervention is to moderate exchange rate movements and prevent excessive volatility. The central bank may intervene if it feels the currency is depreciating too quickly (which can fuel inflation) or appreciating too rapidly (which can harm the competitiveness of exports). By buying or selling its foreign reserves, the central bank can manage the rate to keep it within a desired, though often undeclared, range. Therefore, intervention is a key feature of a managed floating system, and official reserve transactions are not equal to zero.
Q9Questions
Are the concepts of demand for domestic goods and domestic demand for goods the same?
Solution
No, in an open economy, the concepts of 'demand for domestic goods' and 'domestic demand for goods' are not the same. They differ in how they account for imports and exports.
-
Domestic Demand for Goods: This refers to the total spending by domestic residents, firms, and the government on all goods and services, irrespective of where they are produced (domestically or abroad). It is the sum of domestic consumption (C), investment (I), and government spending (G).
- Domestic Demand for Goods = C + I + G This includes spending on both domestically produced goods and imported goods.
-
Demand for Domestic Goods: This refers to the total demand for goods and services that are produced within the country's borders. It includes spending by domestic residents (C + I + G) minus their spending on foreign goods (Imports, M), plus spending by foreigners on domestic goods (Exports, X).
- Demand for Domestic Goods = C + I + G + X - M
The key difference is that domestic demand includes imports and excludes exports, while the demand for domestic goods excludes imports and includes exports.
Q10Questions
What is the marginal propensity to import when ? What is the relationship between the marginal propensity to import and the aggregate demand function?
Solution
Given the import function M = 60 + 0.06Y:
- The marginal propensity to import (m) is the fraction of an additional unit of income that is spent on imports. In the given equation, it is the coefficient of income (Y). Therefore, the marginal propensity to import (m) is 0.06.
Relationship with the Aggregate Demand Function:
The marginal propensity to import (m) acts as a leakage from the circular flow of income and reduces the slope of the aggregate demand (AD) function.
In an open economy, the aggregate demand is given by AD = C + I + G + X - M.
Assuming C = cYd and M = mY (ignoring autonomous parts for simplicity), the AD function depends on income (Y). When income increases by one unit, consumption of domestic goods increases by 'c', but spending on imports increases by 'm'. This spending on imports does not generate income within the domestic economy.
Therefore, the induced part of aggregate demand that falls on domestic goods is (c - m)Y. This means the slope of the AD curve in an open economy is (c - m), which is flatter than the slope of the AD curve in a closed economy (which is just 'c'). A higher marginal propensity to import leads to a larger leakage, a flatter AD curve, and a smaller value for the autonomous expenditure multiplier.
Q11Questions
Why is the open economy autonomous expenditure multiplier smaller than the closed economy one?
Solution
The open economy autonomous expenditure multiplier is smaller than the closed economy multiplier because of an additional leakage from the circular flow of income: imports.
-
Closed Economy Multiplier: The formula is 1 / (1 - c), where 'c' is the marginal propensity to consume. In a closed economy, when there is an autonomous increase in spending (like government expenditure), it becomes income for someone, who then spends a fraction 'c' of it. This entire amount is spent on domestic goods, generating further domestic income.
-
Open Economy Multiplier: The formula is 1 / (1 - c + m), where 'm' is the marginal propensity to import.
Explanation:
In an open economy, when income increases, a portion of this increased income is spent on domestically produced goods (as determined by 'c'), but another portion is spent on imported goods (as determined by 'm'). The amount spent on imports does not generate further income within the domestic economy; instead, it becomes income for foreign producers. This spending on imports is a 'leakage' from the domestic income stream at each round of the multiplier process.
Since 'm' is a positive value, the denominator of the open economy multiplier (1 - c + m) is larger than the denominator of the closed economy multiplier (1 - c). A larger denominator results in a smaller value for the multiplier. Thus, the presence of imports dampens the multiplier effect of any change in autonomous spending.
Q12Questions
Calculate the open economy multiplier with proportional taxes, , instead of lump-sum taxes as assumed in the text.
Solution
To calculate the open economy multiplier with proportional taxes, we start with the equilibrium condition for national income (Y).
-
Equilibrium Condition: Y = C + I + G + X - M
-
Behavioural Equations:
- Consumption (C): C = C̄ + c(Yd), where Yd is disposable income.
- Disposable Income (Yd): Yd = Y - T
- Proportional Tax (T): T = tY
- Investment (I): I = Ī (autonomous)
- Government Spending (G): G = Ḡ (autonomous)
- Exports (X): X = X̄ (autonomous)
- Imports (M): M = M̄ + mY
-
Substitute the equations into the equilibrium condition: Y = [C̄ + c(Y - tY)] + Ī + Ḡ + X̄ - [M̄ + mY]
-
Simplify and group terms with Y: Y = C̄ + cY - ctY + Ī + Ḡ + X̄ - M̄ - mY Now, move all terms containing Y to the left side of the equation: Y - cY + ctY + mY = C̄ + Ī + Ḡ + X̄ - M̄
-
Factor out Y: Y(1 - c + ct + m) = Ā (where Ā represents all autonomous expenditure components) This can also be written as: Y(1 - c(1 - t) + m) = Ā
-
Solve for Y to find the multiplier: Y = [1 / (1 - c(1 - t) + m)] × Ā
Therefore, the open economy multiplier with proportional taxes is:
Multiplier = 1 / (1 - c(1 - t) + m)
Q13Questions
Suppose (a) Find equilibrium income. (b) Find the net export balance at equilibrium income (c) What happens to equilibrium income and the net export balance when the government purchases increase from 40 and 50 ?
Solution
Given the following equations:
C = 40 + 0.8Yd
T = 50
I = 60
G = 40
X = 90
M = 50 + 0.05Y
(a) Find equilibrium income (Y)
First, define disposable income (Yd):
Yd = Y - T = Y - 50
The equilibrium condition is Y = C + I + G + X - M.
Substitute the given values:
Y = [40 + 0.8(Y - 50)] + 60 + 40 + 90 - (50 + 0.05Y)
Y = 40 + 0.8Y - 40 + 60 + 40 + 90 - 50 - 0.05Y
Group the Y terms and the constant terms:
Y = (0.8Y - 0.05Y) + (40 - 40 + 60 + 40 + 90 - 50)
Y = 0.75Y + 140
Y - 0.75Y = 140
0.25Y = 140
Y = 140 / 0.25
Y = 560
The equilibrium income is 560.
(b) Find the net export balance at equilibrium income
Net Exports (NX) = Exports (X) - Imports (M)
NX = 90 - (50 + 0.05Y)
Substitute the equilibrium income Y = 560:
NX = 90 - (50 + 0.05 × 560)
NX = 90 - (50 + 28)
NX = 90 - 78
NX = 12
The net export balance is a surplus of 12.
(c) G increases from 40 to 50
The change in government purchases (ΔG) = 50 - 40 = 10.
New Equilibrium Income:
We can use the multiplier to find the change in income.
Multiplier = 1 / (1 - c + m) = 1 / (1 - 0.8 + 0.05) = 1 / 0.25 = 4
Change in income (ΔY) = Multiplier × ΔG = 4 × 10 = 40
New Equilibrium Income (Y') = Old Y + ΔY = 560 + 40 = 600
New Net Export Balance:
New Imports (M') = 50 + 0.05Y' = 50 + 0.05 × 600 = 50 + 30 = 80
New Net Exports (NX') = X - M' = 90 - 80 = 10
When government purchases increase to 50:
- Equilibrium income increases to 600.
- The net export surplus decreases to 10.
Q14Questions
In the above example, if exports change to , find the change in equilibrium income and the net export balance.
Solution
We start from the original equilibrium calculated in the previous question:
Original Equilibrium Income (Y) = 560
Original Net Exports (NX) = 12
Original Exports (X) = 90
The exports change to X' = 100. This means the change in exports (ΔX) = 100 - 90 = 10.
The multiplier, as calculated before, is 4. (Multiplier = 1 / (1 - c + m) = 1 / (1 - 0.8 + 0.05) = 4).
1. Find the change in equilibrium income
The change in equilibrium income (ΔY) is the multiplier times the change in autonomous spending (in this case, ΔX).
ΔY = Multiplier × ΔX
ΔY = 4 × 10
ΔY = 40
The new equilibrium income (Y') will be:
Y' = Original Y + ΔY = 560 + 40 = 600
2. Find the new net export balance
First, calculate the new level of imports at the new equilibrium income of 600.
New Imports (M') = 50 + 0.05Y' = 50 + 0.05 × 600 = 50 + 30 = 80
Next, calculate the new net export balance (NX') using the new level of exports and imports.
New Net Exports (NX') = New Exports (X') - New Imports (M')
NX' = 100 - 80
NX' = 20
Conclusion:
When exports increase to 100:
- The equilibrium income increases by 40, reaching a new level of 600.
- The net export balance increases to a surplus of 20.
Q15Questions
Suppose the exchange rate between the Rupee and the dollar was Rs. $30=1 $$ in the year 2010. Suppose the prices have doubled in India over 20 years while they have remained fixed in USA. What, according to the purchasing power parity theory will be the exchange rate between dollar and rupee in the year 2030.
Solution
The Purchasing Power Parity (PPP) theory states that the nominal exchange rate between two currencies will adjust to reflect the changes in the price levels of the two countries.
The formula for PPP is: e = P_domestic / P_foreign
Step 1: Define the initial situation (Year 2010)
- Nominal Exchange Rate (e_2010) = Rs. 30 per $
- Let the price level in India be P_India
- Let the price level in USA be P_USA
According to PPP in 2010: 30 = P_India / P_USA
Step 2: Define the situation after 20 years (Year 2030)
- Prices in India have doubled. So, the new price level in India (P'_India) = 2 × P_India
- Prices in the USA have remained fixed. So, the new price level in the USA (P'_USA) = P_USA
Step 3: Calculate the new exchange rate using PPP
According to PPP theory, the new exchange rate (e_2030) will be:
e_2030 = P'_India / P'_USA
e_2030 = (2 × P_India) / P_USA
e_2030 = 2 × (P_India / P_USA)
We know from Step 1 that (P_India / P_USA) = 30. Substituting this value:
e_2030 = 2 × 30
e_2030 = 60
Conclusion:
According to the purchasing power parity theory, the exchange rate between the dollar and the rupee in the year 2030 will be Rs. 60 = 1$.
Q16Questions
If inflation is higher in country A than in Country B , and the exchange rate between the two countries is fixed, what is likely to happen to the trade balance between the two countries?
Solution
If inflation is higher in country A than in country B under a fixed exchange rate system, the trade balance of country A is likely to worsen, moving towards a deficit or an increased deficit.
Here is the explanation:
-
Relative Price Change: Higher inflation in country A means that the prices of goods produced in country A (P_A) are rising faster than the prices of goods produced in country B (P_B).
-
Effect on Real Exchange Rate: The real exchange rate (RER) is the relative price of foreign goods in terms of domestic goods (RER = e × P_B / P_A). Since the nominal exchange rate (e) is fixed and P_A is rising faster than P_B, the real exchange rate for country A will decrease. This makes country A's goods relatively more expensive compared to country B's goods.
-
Impact on Exports: Because goods from country A are now relatively more expensive for consumers in country B and the rest of the world, the demand for country A's exports will fall.
-
Impact on Imports: At the same time, goods from country B are now relatively cheaper for consumers in country A. This will lead to an increase in demand for imports from country B into country A.
Conclusion:
With exports from country A decreasing and its imports increasing, the trade balance of country A (Exports - Imports) will deteriorate. If it was previously in surplus, the surplus will shrink. If it was balanced, it will move into a deficit. If it was already in deficit, the deficit will become larger.
Q17Questions
Should a current account deficit be a cause for alarm? Explain.
Solution
A current account deficit (CAD) is not necessarily a cause for alarm, but it can be if it is large, persistent, and financed in an unsustainable way. Whether it is alarming depends on the underlying reasons for the deficit and how it is being financed.
A current account deficit means a country is spending more on foreign goods, services, and transfers than it is earning from them. This deficit must be financed by a surplus in the capital account, which means the country is borrowing from abroad or selling its assets to foreigners.
When a CAD might NOT be a cause for alarm:
- Financing Productive Investment: If the borrowed foreign funds are used to finance productive investments (e.g., infrastructure, new factories, technology), it can enhance the country's future productive capacity. This future growth can generate the income needed to repay the foreign debt, making the deficit sustainable. In this case, the CAD reflects a healthy economy that offers attractive investment opportunities.
When a CAD IS a cause for alarm:
- Financing Consumption: If the deficit is driven by borrowing to finance current consumption (e.g., imported consumer goods), it does not contribute to future productive capacity. This leads to an accumulation of foreign debt without creating the means to repay it, which is unsustainable in the long run.
- Large and Persistent Deficits: A large and persistent CAD can be a sign of structural weaknesses in an economy, such as low competitiveness or a lack of domestic savings. It can lead to a significant build-up of external liabilities.
- Risk of Sudden Stop: Heavy reliance on short-term foreign capital ('hot money') to finance the deficit is risky. A sudden loss of investor confidence can lead to a rapid outflow of this capital, triggering a balance of payments crisis, a sharp depreciation of the currency, and a severe economic recession.
Q18Questions
Suppose , taxes are 20 per cent of income, . Calculate equilibrium income, the budget deficit or surplus and the trade deficit or surplus.
Solution
Given the following equations:
C = 100 + 0.75Yd
I = 500
G = 750
Taxes (T) = 20% of income = 0.2Y
X = 150
M = 100 + 0.2Y
1. Calculate Equilibrium Income (Y)
First, define disposable income (Yd):
Yd = Y - T = Y - 0.2Y = 0.8Y
The equilibrium condition is Y = C + I + G + X - M.
Substitute the given values:
Y = [100 + 0.75(0.8Y)] + 500 + 750 + 150 - (100 + 0.2Y)
Y = 100 + 0.6Y + 500 + 750 + 150 - 100 - 0.2Y
Group the Y terms and the constant terms:
Y = (0.6Y - 0.2Y) + (100 + 500 + 750 + 150 - 100)
Y = 0.4Y + 1400
Y - 0.4Y = 1400
0.6Y = 1400
Y = 1400 / 0.6
Y = 2333.33
The equilibrium income is 2333.33.
2. Calculate the Budget Deficit or Surplus
Budget Balance = Government Revenue (T) - Government Spending (G)
First, calculate total tax revenue (T):
T = 0.2Y = 0.2 × 2333.33 = 466.67
Now, calculate the budget balance:
Budget Balance = 466.67 - 750 = -283.33
Since the result is negative, there is a budget deficit of 283.33.
3. Calculate the Trade Deficit or Surplus
Trade Balance (Net Exports, NX) = Exports (X) - Imports (M)
First, calculate total imports (M) at the equilibrium income:
M = 100 + 0.2Y = 100 + 0.2 × 2333.33 = 100 + 466.67 = 566.67
Now, calculate the trade balance:
Trade Balance = 150 - 566.67 = -416.67
Since the result is negative, there is a trade deficit of 416.67.
Q19Questions
Discuss some of the exchange rate arrangements that countries have entered into to bring about stability in their external accounts.
Solution
Countries have entered into various exchange rate arrangements to bring stability to their external accounts and foster predictable conditions for international trade and investment. The main systems are:
-
Fixed Exchange Rate System:
- Description: In this system, the government or central bank fixes the value of its currency against another major currency (like the US dollar), a basket of currencies, or a commodity like gold. The central bank must hold large foreign exchange reserves and be ready to buy or sell its currency to maintain this fixed rate.
- Stability: This system provides a high degree of stability and certainty for international transactions, which encourages trade and investment. It also imposes discipline on domestic monetary policy.
- Example: The Bretton Woods System (1944-1971) where currencies were pegged to the US dollar, which was in turn pegged to gold.
-
Flexible (or Floating) Exchange Rate System:
- Description: The exchange rate is determined by the free-market forces of demand and supply without any government intervention.
- Stability: While it can be volatile, this system provides stability through an automatic adjustment mechanism. For example, a trade deficit leads to currency depreciation, which makes exports cheaper and imports expensive, automatically helping to correct the deficit. It also allows a country to pursue an independent monetary policy.
-
Managed Floating Exchange Rate System:
- Description: This is a hybrid system where the exchange rate is largely determined by market forces, but the central bank intervenes periodically to prevent excessive fluctuations or to guide the currency toward a desired level. It is also known as a 'dirty float'.
- Stability: This system attempts to combine the benefits of both fixed and flexible systems. It allows for automatic adjustment while providing a degree of stability by preventing extreme volatility that could harm the economy.
- Example: This is the most common system used by countries around the world today, including India.
