When converting GDP at market price to NNP at factor cost, the candidate subtracts net indirect taxes before depreciation, or adds net factor income from abroad to NDP instead of GDP, producing an internally inconsistent aggregate.
The candidate memorises the labels GDP, GNP, NDP and NNP but not the fixed sequence of adjustments, and treats net factor income from abroad as an optional add-on rather than a directional adjustment.
What to do instead
Write and reuse a single ladder: GDP at MP minus depreciation = NDP at MP; minus net indirect taxes = NDP at FC; plus net factor income from abroad = NNP at FC. Practise ten numerical conversions in both directions and check that GNP at MP = GDP at MP + NFIA.
Adds the full sales value of every firm, including intermediate goods such as steel sold to car manufacturers, when estimating national income by the output method.
The candidate confuses total output with value added and does not check whether a good is resold or embodied in another product during the same year.
What to do instead
Before summing, label each item as intermediate or final. Use value added = sales + change in stock minus intermediate consumption, or sum final expenditure. Work through one example containing a farmer, a miller and a baker, showing why only the final bread value or the sum of value added is counted.
Calculates total deposit creation from an initial deposit by multiplying it by the cash reserve ratio, for example saying Rs 1,000 at 20% CRR creates only Rs 200 of deposits, instead of using the reciprocal.
The candidate remembers that CRR is central to credit creation but reverses the multiplier, and does not distinguish the initial deposit from excess reserves.
What to do instead
Use money multiplier = 1/CRR and total deposits = initial excess reserves x 1/CRR. Show that Rs 1,000 of excess reserves at 20% CRR supports Rs 5,000 of total deposits and Rs 4,000 of new credit. Also state the assumptions: no cash leakage and no excess reserves held by banks.
States that raising the repo rate or CRR increases money supply, or that RBI purchases of government securities in the open market drain bank reserves.
The candidate memorises tool names without the direction of effect, and conflates the RBI's action with the resulting change in reserves.
What to do instead
Build a two-column direction table: expansionary policy = lower repo rate, lower CRR, lower reverse repo, RBI net OMO purchases; contractionary policy = the opposites. For each tool, write 'action -> reserves -> money supply' in one line and test yourself with mixed-order questions.
Uses the government-expenditure multiplier 1/(1-MPC) for a lump-sum tax cut, or claims output must rise by exactly 1/(1-MPC) times a spending increase even when the economy is at full employment.
One multiplier formula is applied to every fiscal change, and the candidate ignores the difference between expenditure and tax multipliers and the capacity constraint.
What to do instead
Keep three separate formulas: government expenditure multiplier = 1/(1-MPC); lump-sum tax multiplier = -MPC/(1-MPC); balanced-budget multiplier = 1. Add the condition that at full employment a demand increase mainly raises prices or imports rather than real output.
Defines primary deficit as fiscal deficit plus interest payments, or says revenue deficit equals fiscal deficit minus interest payments.
The three deficit terms are learned as overlapping labels rather than as a hierarchy, so the candidate reverses the interest-payment adjustment.
What to do instead
Memorise fiscal deficit = total expenditure - total receipts excluding borrowings; revenue deficit = revenue expenditure - revenue receipts; primary deficit = fiscal deficit - interest payments. Confirm with a numerical example where interest payments are positive and check that primary deficit is smaller than fiscal deficit.
Records FDI inflows and changes in foreign exchange reserves as current-account items, or places export earnings in the capital account because money is entering the country.
The candidate classifies transactions by the direction of money flow rather than by the nature of the underlying transaction.
What to do instead
Use the rule: current account = goods, services, income and unilateral transfers; capital account = changes in foreign assets and liabilities, including FDI, loans and reserve changes. Draw a two-column T-account and classify ten mixed items by asking what is being exchanged, not which way the money moves.
Describes the 1991 reforms as a continuation of the pre-1991 licensing system, or defines privatisation as the complete sale of all public-sector undertakings.
Reform slogans are memorised without dates or scope, and liberalisation, privatisation and globalisation are collapsed into one undifferentiated package.
What to do instead
Make a two-period timeline: 1950-90 (planning, licensing, import substitution) and post-1991 (deregulation, devaluation, tax reform, disinvestment, greater foreign trade and investment). For privatisation, note partial disinvestment and strategic sale rather than blanket sale, and give one concrete policy example for each of the three reform words.
Treats informalisation as identical to the unorganised sector and concludes that a rising share of informal employment automatically improves worker welfare, or says demographic dividend is guaranteed because the population is young.
The candidate uses informal and unorganised interchangeably and ignores the conditions attached to the demographic dividend.
What to do instead
Define informal employment by the absence of social security and written contracts, not by firm size, and note that informalisation can reflect distress. For the demographic dividend, list the required conditions: education, health, job creation, female workforce participation and productive investment. Use one example of a country that captured the dividend and one that did not.
Compares India, Pakistan and China only by current GDP size and concludes China grew fastest simply because it has the largest population, or says China followed import substitution like India after 1978.
The candidate relies on rote headline indicators and lacks a comparative framework linking population, sectoral composition and policy approach.
What to do instead
Compare on a fixed grid: GDP and per capita income, sectoral shares, life expectancy, literacy, poverty and trade openness. Then link policy: China's gradual opening, special economic zones and export orientation after 1978; India's licensing era and 1991 reforms; Pakistan's mixed record with agriculture and external dependence. Reject single-cause explanations and cite at least two indicators before drawing a conclusion.
