JAIIB Paper 1 Module B Quiz 7

Microeconomics studies decisions made by individual consumers, households and firms, including consumption and saving choices. Macroeconomics examines aggregates such as total national saving, investment, output and employment. A household decision can influence aggregate outcomes, but the individual decision itself is a microeconomic topic.

A change in the product‘s own price normally causes a movement along a given demand curve. The law of demand states that, other things equal, a higher price is associated with a lower quantity demanded. A shift of the entire curve instead results from a non-price determinant such as income, tastes, expectations or the price of a related good.

For a normal good, demand increases when consumer income increases, other things being equal. For an inferior good, demand generally decreases as income rises because consumers switch toward preferred alternatives. Giffen goods are a rare theoretical case involving an inferior good and a strong income effect; they are not implied merely by an increase in demand with income.

A binding price ceiling is set below the equilibrium price. At the lower controlled price, consumers want to buy more while producers are willing to supply less, creating excess demand or a shortage. The ceiling does not automatically restore market clearing; non-price allocation or informal-market effects may arise.

Cross-price elasticity measures the percentage change in demand for one good in response to a percentage change in the price of another. A positive value generally indicates substitutes: when coffee becomes more expensive, demand for tea may rise. Complements tend to have negative cross-price elasticity because a higher price of one reduces demand for the other.

Disinflation means inflation remains positive but slows—for example, annual inflation falls from 6% to 4%. Deflation means the general price level declines over a period, corresponding to negative inflation. The distinction matters because slower price increases are not the same as an overall fall in prices.

India‘s M1 broadly includes currency with the public, demand deposits with the banking system, and other deposits with the RBI. Time deposits are included in broader monetary aggregates, not in M1. Securities and mutual fund units are financial assets but are not components of M1.

A negative supply shock raises firms‘ costs and reduces the quantity they are willing or able to produce at each price level. This can raise the general price level while lowering real output, a pattern often called cost-push inflation or stagflation when accompanied by stagnant activity. It differs from demand-pull inflation, which originates in stronger aggregate demand.

In the classical loanable-funds view, the interest rate adjusts to bring planned saving into line with planned investment. A higher interest rate generally encourages saving and discourages investment, while a lower rate tends to do the opposite. Keynes‘ liquidity-preference approach instead emphasises money demand and money supply in determining the rate of interest.

The speculative motive relates to uncertainty about future interest rates and bond prices. Bond prices and yields move inversely: someone expecting interest rates to rise may expect bond prices to fall and may prefer holding money temporarily. Transactions demand is instead associated with routine payments, while precautionary demand concerns unforeseen needs.

With a fixed price level, a larger nominal money supply increases real money balances. At a given level of income, the interest rate consistent with money-market equilibrium falls; equivalently, the LM curve shifts rightward or downward. The IS curve represents goods-market equilibrium and does not shift solely because the money supply changes.

A conventional business cycle moves through expansion, peak, contraction and trough. Output and employment generally rise during expansion, reach a cyclical high at the peak, decline during contraction, and reach a low at the trough before recovery. Actual cycles differ in duration and severity, and not every downturn has the same pattern.

When the central bank sells securities, buyers pay for them and funds are transferred out of the banking system to the central bank. This generally drains reserves and tightens liquidity, other things equal. A purchase generally injects reserves. Open-market operations are distinct from fiscal spending decisions by the government.

CRR is the prescribed share of specified bank liabilities that must be maintained as cash balances with the central bank. A reduction lowers the amount tied up in required reserves and may increase lendable liquidity. It does not mechanically guarantee a one-for-one fall in lending rates, since transmission depends on funding costs, risk, demand and other conditions.

An increase in government expenditure directly raises aggregate demand, other things equal, and is an example of expansionary fiscal policy. Borrowing to finance it may also affect interest rates, debt and private investment, depending on economic conditions. Monetary policy is conducted through instruments such as policy rates and liquidity operations, not the budget‘s expenditure decision itself.

GDP deflator = (Nominal GDP ÷ Real GDP) × 100. Here, (330 ÷ 300) × 100 = 110. A deflator of 110 means the measured price level of domestically produced final goods and services is 10% above the base-year level, assuming the standard index base of 100. It is not itself the annual inflation rate unless compared with a prior period‘s deflator.

GDP measures the market value of final goods and services produced within a country‘s economic territory during a period. A newly produced machine is current investment and is counted. A used car‘s original production was counted earlier; the resale itself is not new production, although any current dealer service is counted. Transfer payments and share purchases do not represent current production.

GDP per capita is GDP divided by population. If population grows faster proportionately than GDP, GDP per capita falls. This indicator is an average and does not reveal how income is distributed, nor does it measure every aspect of welfare, but it helps distinguish aggregate output growth from output per person.

Fiscal deficit broadly measures the government‘s total expenditure minus total receipts excluding borrowings—that is, revenue receipts plus non-debt capital receipts. It indicates the borrowing requirement for the year. It is distinct from the revenue deficit, which compares revenue expenditure with revenue receipts, and from the primary deficit, which subtracts interest payments from the fiscal deficit.

Primary deficit is calculated as fiscal deficit minus interest payments. It indicates the current year‘s borrowing requirement excluding the interest burden arising from past debt. A low primary deficit does not mean the government has no fiscal deficit, because interest payments may still be substantial.
