FAQs on CBSE Class 12 Economics Chapter 6 Open Economy Macroeconomics – NCERT Solutions 2025-26
1. What is the correct step-by-step approach to solving exchange rate determination problems as per NCERT Solutions for Class 12 Economics Chapter 6?
The best way to solve exchange rate determination problems is to follow a structured method:
- Identify the type of exchange rate system (fixed, flexible, managed floating).
- Set up the demand and supply equations for foreign currency as required in the question.
- Use the point where demand equals supply to find the equilibrium rate.
- Apply given values and solve using algebraic methods.
- For calculation-based questions, carefully substitute numerical values and show each step as per the CBSE marking pattern.
2. How can students avoid common mistakes while answering open economy multiplier questions in CBSE exams?
To avoid errors in open economy multiplier problems:
- Write the standard formula for both closed and open economy multipliers before starting calculations.
- Carefully distinguish autonomous from induced variables (like imports or taxes).
- Include all terms: consumption, taxation, imports, exports, government spending, and investments.
- Show each algebraic rearrangement clearly.
- Double-check the denominator, especially when proportional taxes or marginal propensity to import are involved.
3. What method should be used to systematically present differences between devaluation and depreciation as per CBSE Class 12 NCERT Solutions?
When asked to distinguish between devaluation and depreciation, use a tabular format:
- Devaluation occurs when the government officially lowers the value of its currency under a fixed exchange rate system.
- Depreciation takes place when a currency loses value due to market forces in a flexible exchange rate system.
4. Why is calculating the balance of payments (BoP) important when working with NCERT Solutions for this chapter?
Calculating the balance of payments is crucial because it records all international economic transactions of a country. Understanding BoP helps students:
- Apply accounting principles to real-life country data.
- Differentiate between current and capital account items.
- Analyze causes of BoP surplus or deficit.
5. How do step-by-step NCERT Solutions help in clarifying the impact of currency appreciation or depreciation on imports and exports?
NCERT Solutions explain that when a currency appreciates, imports become cheaper and exports become more expensive, possibly reducing export competitiveness. Conversely, depreciation means imports cost more but exports are cheaper, which can boost export volumes. Step-by-step answers help students:
- Connect currency movement to real-world trade scenarios.
- Understand the effect on trade balance and domestic producers.
- Structure answers to earn full marks in CBSE board exams.
6. What is the recommended sequence for breaking down calculations involving marginal propensity to import or proportional taxes in NCERT Solutions for Chapter 6?
CBSE-centric stepwise sequence:
- Write the functional relationship given (e.g., M = 60 + 0.06Y).
- Identify and state the marginal propensity from the equation (here, m = 0.06).
- If proportional taxes are present, clearly indicate the tax rate and its effect on disposable income.
- Substitute all variables into the main equilibrium income formula, showing each algebraic step.
7. How do NCERT Solutions encourage a systematic approach to distinguishing between current account and capital account transactions?
The Solutions recommend listing the key distinguishing features:
- Current account: Deals with export and import of goods/services, income, and unilateral transfers.
- Capital account: Relates to capital transfers and transactions in non-produced, non-financial assets.
8. What steps should be taken to ensure CBSE answer quality when using managed floating exchange rate examples?
To maximize marks:
- Define managed floating (dirty floating) clearly, mentioning its features.
- Include a real-life example, such as RBI intervention to stabilize the rupee.
- Use a diagram if asked for graphical representation.
- Highlight the blend of market-driven rates and occasional central bank intervention.
9. Why is it recommended to solve all end-of-chapter problems stepwise in this NCERT Solutions folder?
Solving problems stepwise ensures that students:
- Do not miss any calculation or formula application.
- Achieve full marks for method even if the final answer is slightly wrong (as per CBSE policy).
- Gain confidence in applying theory to practical numerical and conceptual CBSE questions.
10. How does following the CBSE prescribed method in NCERT Solutions improve performance in board exams for Class 12 Economics?
Applying the CBSE method as structured in NCERT Solutions helps in:
- Ensuring all formulas and calculations are displayed stepwise for partial marking.
- Maintaining answer structure, which is valued by board examiners.
- Addressing conceptual and practical problems with equal clarity.
