JAIIB Paper 1 Module B Quiz 9

Microeconomics studies individual economic units and particular markets, including the demand for a specific product. Macroeconomics studies economy-wide aggregates such as overall output, inflation and unemployment. The question isolates one product market and holds other factors constant, so it is microeconomic analysis.

A mixed economy combines market mechanisms and private enterprise with government ownership, regulation, public services or policy intervention. The relative roles of the state and markets differ by country and sector; neither the state nor private markets need control every decision.

For a normal good, higher income increases demand at each price, shifting the demand curve to the right. With the supply curve unchanged, the new equilibrium generally has a higher price and a higher quantity. A movement along a demand curve is caused by a change in the good’s own price, not income.

Substitute goods can satisfy similar wants. When tea becomes more expensive, some consumers switch toward coffee, increasing coffee demand. Complementary goods are typically consumed together; a price rise in one usually reduces demand for the other.

A binding price ceiling prevents the price from rising to its market-clearing level. At the controlled lower price, consumers want to buy more while producers are willing to supply less, creating excess demand or a shortage. The actual quantity traded may then be limited by the amount available.

CPI tracks price changes for a basket of goods and services relevant to consumers and is widely used to assess retail inflation. WPI tracks price movements for goods at the wholesale level under its defined coverage and does not represent the same consumer basket or services coverage. The two indices can therefore move at different rates.

Inflation over the interval is calculated as ((current index − previous index) ÷ previous index) × 100. Here, ((218 − 200) ÷ 200) × 100 = (18 ÷ 200) × 100 = 9%. The index rose by 18 points, but the inflation rate is the percentage change relative to the starting value.

Cost-push inflation occurs when higher input costs—such as energy, raw materials or wages not matched by productivity—raise production costs and prices. Demand-pull inflation is associated with aggregate demand rising relative to productive capacity. Disinflation means inflation is slowing, while deflation means the general price level is falling.

In the classical theory, the interest rate adjusts to balance saving and investment. Saving represents the supply of loanable funds, while investment represents demand for funds. The theory typically assumes that the interest rate coordinates these real-sector decisions, unlike Keynes’ liquidity-preference approach, which focuses on money demand and money supply.

The speculative motive concerns the choice between holding money and interest-bearing securities in light of expectations about future interest rates and bond prices. Since bond prices and interest rates move inversely, an investor expecting rates to rise may expect bond prices to fall and prefer to hold money temporarily. Transactions and precautionary motives are distinct reasons for holding money.

With a higher nominal money supply and a given price level, real money balances increase. At a given income level, the interest rate that equilibrates money demand with money supply is lower, so the LM curve shifts right/downward. In the full IS–LM equilibrium, output and interest rates adjust together; the result depends on the model’s assumptions.

A leading indicator tends to change direction before the broader economy does and can therefore provide an early signal of turning points. A coincident indicator moves broadly with current activity, while a lagging indicator typically confirms a change after it has occurred. Such indicators are signals, not guarantees of future outcomes.

When the central bank sells securities, buyers pay for them and funds are transferred out of the banking system to the central bank. This normally drains reserves and tightens liquidity, other things equal. A central-bank purchase generally injects reserves. The ultimate effect on broad money and credit depends on banks’ behaviour and other factors.

In the simplest deposit-multiplier model, the money multiplier is inversely related to the required reserve ratio (m = 1/rr under restrictive assumptions). A higher reserve ratio means a smaller fraction of deposits is available to support additional lending and deposit creation, so the simple multiplier falls. Actual money creation is more complex and depends on cash preferences, excess reserves and credit demand.

Expansionary fiscal policy raises aggregate demand through higher government expenditure, lower taxes or a combination of both. It may be used to support output and employment during a downturn. Its effect on output depends on the size of the multiplier, spare capacity, financing, monetary-policy responses and other conditions.

Using the relationship given in the question, GDP at factor cost = ₹300 lakh crore − ₹25 lakh crore = ₹275 lakh crore. Net indirect taxes are indirect taxes less subsidies. The question explicitly supplies the simplified relationship to avoid ambiguity arising from changes in national-accounting presentation.

Gross national income is broadly GDP plus net primary (factor) income receivable from the rest of the world. GDP is based on production within the domestic territory, regardless of who owns the factors of production. Net exports are exports minus imports and are only one component of expenditure-based GDP.

Salaries are recurring expenditure for government operations and are classified as revenue expenditure. Construction of a new railway line and acquisition of land normally create or acquire assets and are capital expenditure. Repayment of loan principal is a capital disbursement, not revenue expenditure.

Revenue deficit = revenue expenditure − revenue receipts. Therefore, ₹29 lakh crore − ₹24 lakh crore = ₹5 lakh crore. It indicates that current revenue receipts are insufficient to meet revenue expenditure. It differs from fiscal deficit, which measures the government’s total borrowing requirement after accounting for non-debt capital receipts.

Funds raised through government borrowing, including issuance of dated securities, are debt capital receipts because they create a repayment obligation. Tax revenue is a revenue receipt; non-debt capital receipts include items such as recovery of loans and disinvestment proceeds. Borrowing is not classified as expenditure.
