JAIIB Paper 1 Module B Quiz 6

When two goods are substitutes, a rise in the price of one tends to increase demand for the other, other things equal. Consumers may switch from tea to coffee because coffee has become relatively less expensive. This is a shift in the demand curve for coffee, not merely a movement along coffee‘s demand curve, because the price of coffee itself has not changed.

Lower production costs make suppliers willing and able to offer more at each possible price, shifting the supply curve to the right. With demand unchanged, the new equilibrium generally has a lower price and a higher quantity. The outcome assumes a competitive-market model and no offsetting change in demand or other supply conditions.

Price elasticity of demand measures the percentage change in quantity demanded divided by the percentage change in price. Its absolute value is 0.4, which is less than one, so demand is price-inelastic over the range measured. Quantity demanded changes proportionately less than price. The negative sign reflects the usual inverse relationship between price and quantity demanded.

M1 is a narrow measure of money and includes currency with the public, demand deposits with the banking system, and other deposits with the Reserve Bank of India. It focuses on highly liquid means of payment. Broader aggregates add specified types of deposits and other components; the exact published definitions should be checked in RBI statistical releases when an exam question asks for the current official series.

The inflation rate based on a price index is the percentage change in the index: (159 − 150) / 150 × 100 = 6%. The base value is the earlier index level, not the later level. A price index measures the change in a specified basket or set of prices; the result depends on the index used and the period compared.

The Fisher relationship approximates the nominal interest rate as the real interest rate plus expected inflation. If expected inflation rises and the real rate and risk premia are unchanged, the nominal rate tends to rise by approximately the same amount. In practice, nominal rates may not adjust one-for-one immediately because of policy, risk, taxes and expectations.

In the speculative motive, people choose between holding liquid money and interest-bearing assets such as bonds based partly on expectations of future interest rates and bond prices. If they expect rates to rise, existing bond prices are expected to fall, so they may prefer to hold money temporarily. This is distinct from transactions demand, which is linked to routine payments, and precautionary demand, which addresses unexpected needs.

The LM curve represents money-market equilibrium. Higher money demand at a given income and interest rate creates excess demand for money; for equilibrium with unchanged real money supply, a higher interest rate is generally needed at each income level. Thus LM shifts left/up in the conventional diagram. The IS curve represents goods-market equilibrium and does not shift directly from this money-demand change.

A typical business-cycle sequence is peak, contraction, trough and expansion, followed by another peak. The peak is the turning point at a high level of activity; contraction is the downturn; the trough is the low point; and expansion is the upswing. Actual economic cycles do not always follow a perfectly regular timetable, and official dating uses multiple indicators.

The Cash Reserve Ratio (CRR) specifies the share of a bank‘s net demand and time liabilities that must be maintained as cash balance with the RBI under the applicable framework. Changing CRR affects the funds banks can deploy, making it a quantitative monetary-policy instrument. It differs from qualitative measures such as moral suasion, and it should not be confused with SLR assets maintained in prescribed liquid forms.

A policy-rate increase is generally a tightening measure. If it transmits to market and lending rates, borrowing becomes more expensive and interest-sensitive consumption and investment may moderate, easing aggregate demand and inflationary pressure over time. The strength and timing of transmission depend on liquidity, bank pricing, expectations, contract structures and the source of inflation; a rate increase cannot directly produce more food or energy supply.

CRR requires banks to maintain prescribed cash balances with the RBI. SLR requires them to maintain a prescribed proportion of relevant liabilities in specified liquid assets under the applicable rules, such as cash, gold or eligible unencumbered securities. Both are prudential/liquidity requirements, but the place and form in which the assets are maintained differ. Exact regulatory details should be checked against current RBI directions.

An increase in personal income-tax rates, with spending unchanged, is generally contractionary because it reduces disposable income and can restrain private consumption. The final effect depends on the tax base, taxpayer behaviour, timing and other economic conditions. This is a discretionary fiscal measure, unlike automatic changes in tax receipts that occur as incomes change without a new policy decision.

In the simplest model without taxes or imports, the expenditure multiplier is 1/(1 − MPC). With MPC = 0.75, the multiplier is 1/(1 − 0.75) = 1/0.25 = 4. This means an initial autonomous spending change can generate a total equilibrium output change four times as large in the model. Real-world multipliers are affected by taxes, imports, capacity constraints and monetary responses.

Nominal GDP values output at current-period prices, so it can rise when prices increase even if the quantity of production is unchanged. Real GDP attempts to remove the effect of price changes using a suitable price measure and reference method. The GDP deflator is commonly used to relate nominal GDP to real GDP and captures prices of domestically produced final goods and services.

Value added is the value of output minus the value of intermediate consumption. Here it is ₹500 − ₹320 = ₹180. Summing value added across production stages avoids double counting the same intermediate inputs. The question isolates the basic calculation; national accounts apply more detailed definitions and adjustments when compiling sectoral and aggregate data.

GDP measures the value of final goods and services produced within the domestic economy during a period. A transfer payment redistributes purchasing power but is not itself payment for current production of a good or service. If the recipient later spends the transfer on newly produced goods or services, that production is included in GDP through the relevant expenditure component; the transfer itself is not counted as output.

Primary deficit equals fiscal deficit minus interest payments. Therefore, ₹6 lakh crore − ₹2 lakh crore = ₹4 lakh crore. The measure indicates the current fiscal gap excluding interest costs on past debt. It is not the same as revenue deficit, which compares revenue expenditure with revenue receipts, or the overall fiscal deficit itself.

Tax revenue, such as income tax or GST, is ordinarily classified as a revenue receipt. Borrowings create liabilities and are capital receipts; recovery of loans and proceeds from disinvestment are generally non-debt capital receipts. Classification matters because the revenue deficit and fiscal deficit use different sets of receipts and expenditure, so exam questions should distinguish them carefully.

The expenditure identity is GDP = consumption + investment + government purchases + exports − imports. Net exports equal exports minus imports, so an increase in imports with exports unchanged reduces net exports. With the other expenditure components unchanged, the identity implies lower measured GDP. Imports are subtracted because their value is included in consumption, investment or government purchases but represents production outside the domestic economy.
