Excess Demand and Deficient Demand

Answer: A — AD exceeds full-employment AS. Excess Demand occurs specifically when planned AD is GREATER than what the economy can produce at FULL EMPLOYMENT (recall Chapter 7’s definition — all willing workers already employed, all resources fully utilised). Since output CANNOT rise beyond this ceiling, the extra spending can ONLY show up as HIGHER PRICES (inflation), not more actual goods and services.

Answer: A — Gap between actual AD and the AD required for full-employment equilibrium. The Inflationary Gap is a PRECISE measurement tool — it tells policymakers EXACTLY how much they need to REDUCE Aggregate Demand (through contractionary monetary or fiscal policy) to bring the economy back to a NON-INFLATIONARY full-employment equilibrium, without any painful reduction in output (since output was already at its maximum anyway).

Answer: A — Excess Demand/Inflation. A tax cut leaves households with MORE disposable income, which typically INCREASES Consumption spending (C). If this happens when the economy is ALREADY at full employment (output cannot rise any further, since all resources are fully utilised), this extra demand CANNOT be met by MORE production — it can ONLY be absorbed through HIGHER PRICES, creating (or worsening) Excess Demand/Inflation.

Answer: A — Deficit financing causes Excess Demand. Deficit financing involves the government spending BEYOND its tax revenue, funding the shortfall by BORROWING from the Central Bank (which effectively CREATES new money). This INJECTS extra purchasing power into the economy WITHOUT a corresponding increase in output, directly fuelling Excess Demand. Options B, C and D are all CONTRACTIONARY actions that would instead cause or worsen DEFICIENT demand, not excess demand.

Answer: A — Inflation without output/employment change. Since the economy is ALREADY at full employment (all resources fully utilised, as established in Chapter 7), MORE aggregate demand CANNOT translate into MORE real output or MORE jobs — there is simply no additional capacity to produce more. The ONLY way the economy can “absorb” excess demand is through RISING PRICES (inflation), making this the primary and most direct consequence.

Answer: A — Favours profit-earners/debtors; hurts fixed-income earners. During inflation, PRICES of goods/services rise, and businesses/profit-earners can adjust their prices UPWARD to capture this — their nominal income rises WITH inflation. DEBTORS also benefit since the REAL VALUE of their fixed debt repayments shrinks over time. However, people with FIXED incomes (pensioners receiving a set monthly amount, salaried workers whose wages adjust slowly) find their REAL purchasing power ERODING, since their income does NOT rise as fast as prices — a classic inflation-driven income redistribution effect.

Answer: A — AD falls short of full-employment AS, causing involuntary unemployment. Deficient Demand occurs when planned spending is INSUFFICIENT to purchase all the goods/services the economy is CAPABLE of producing at full employment. Firms respond to this WEAK demand by CUTTING PRODUCTION and LAYING OFF workers — directly causing INVOLUNTARY UNEMPLOYMENT (recall Chapter 7’s precise definition: workers WILLING to work at the prevailing wage but unable to find jobs due to insufficient demand).

Answer: A — Gap between actual AD and the AD required for full-employment equilibrium (shortfall direction). The Deflationary Gap tells policymakers PRECISELY how much they need to INCREASE Aggregate Demand (through expansionary monetary or fiscal policy) to eliminate involuntary unemployment and restore the economy to full employment. It is the EXACT MIRROR IMAGE of the Inflationary Gap — one measures an EXCESS, the other measures a SHORTFALL.

Answer: A — Worsening Deficient Demand. Raising Repo Rate and CRR are CONTRACTIONARY tools — they make borrowing MORE expensive, discouraging both household Consumption (fewer loans for big purchases) and firm Investment (costlier to borrow for expansion). If the economy is ALREADY suffering from Deficient Demand/unemployment, applying MORE contractionary policy would be a POLICY ERROR — it would further SHRINK AD, worsening (not fixing) the unemployment problem. The CORRECT response to Deficient Demand is the OPPOSITE: LOWER rates and CRR to EXPAND credit and spending.

Answer: A — Increase Bank Rate, CRR/SLR, Repo Rate, and Sell securities (OMO) — all contractionary. To fight EXCESS Demand, the RBI must CONSISTENTLY apply CONTRACTIONARY tools that REDUCE the money supply and credit availability: raising Bank Rate/Repo Rate makes borrowing costlier; raising CRR/SLR forces banks to hold more reserves, lending less; selling securities via OMO absorbs money FROM the banking system. ALL these actions work TOGETHER in the SAME direction — shrinking AD to bring it back in line with the full-employment AS level, cooling inflation.

Answer: A — Increase Govt Expenditure, Decrease Taxes, Increase Deficit Financing — all expansionary. To fight DEFICIENT Demand, the Government must apply EXPANSIONARY fiscal tools: INCREASING its own spending (G) directly adds to AD (and triggers the Chapter 8 multiplier effect); DECREASING taxes leaves households with MORE disposable income, boosting Consumption; INCREASING deficit financing injects EXTRA money into the economy. Options B, C and D would either WORSEN deficient demand (B, C) or are the WRONG direction for public borrowing (D, which should DECREASE to leave more money with the public, not increase).

Answer: A — The Government Expenditure Multiplier (same as Investment Multiplier, 1÷MPS) amplifies the effect. This directly connects to Chapter 8: an increase in G works EXACTLY like an increase in I — the initial spending becomes INCOME for suppliers/workers, who then spend a fraction (MPC) of THAT income, creating FURTHER rounds of spending, in the SAME decreasing geometric series pattern. Since k=1÷MPS is typically GREATER than 1, a MODEST government spending increase can generate a MUCH LARGER total boost to national income — making it a highly EFFICIENT tool for closing deflationary gaps.

Answer: A — AD = C+I+G; AS = C+S+T in the three-sector model. The THREE-SECTOR economy extends the two-sector model (Households + Firms) by adding the GOVERNMENT sector. On the DEMAND side, Government Expenditure (G) becomes a THIRD component alongside C and I. On the SUPPLY side, Government TAXATION (T) becomes a SECOND “leakage” from income (alongside Saving, S) — since taxed income is NOT available for either consumption or private saving. This is DIFFERENT from the full four-sector model (which additionally includes Net Exports, X−M) covered in later chapters.

Answer: A — Connects to Chapter 1’s Circular Flow “Leakages=Injections” concept. This is a DIRECT callback to the very FIRST chapter of the syllabus: in the Circular Flow of Income, LEAKAGES are amounts withdrawn from the flow of spending (Saving and Taxes, since this money does NOT immediately return as consumer spending), while INJECTIONS are amounts ADDED to the flow from outside current consumer spending (Investment and Government spending). The equilibrium condition I+G=S+T is EXACTLY the general “Injections=Leakages” rule, now applied specifically with Government included as the third sector.

Answer: A — Deficient Demand, since Leakages exceed Injections. When Leakages (S+T = Rs 500 crore) EXCEED Injections (I+G = Rs 450 crore), MORE money is being WITHDRAWN from the circular flow (through saving and taxation) than is being ADDED BACK (through investment and government spending). This causes TOTAL SPENDING in the economy to be INSUFFICIENT relative to output, leading to DEFICIENT DEMAND — National Income will tend to FALL until a new equilibrium is reached where Leakages once again equal Injections (at a LOWER income level).

Answer: A — Bank Credit expansion/contraction affects both demand conditions in opposite ways. Bank Credit is a KEY link between the banking system (Chapter 6) and demand conditions (Chapter 9): when banks LEND MORE FREELY (credit expansion, via the Credit Multiplier from Chapter 6), this INCREASES money supply and spending power, potentially CAUSING or WORSENING Excess Demand. When banks TIGHTEN lending (credit contraction), this DECREASES money supply and spending power, potentially CAUSING or WORSENING Deficient Demand. This demonstrates how Chapter 6 banking concepts directly explain Chapter 9 demand-side problems.

Answer: A — Tax revenue falls as incomes and business activity shrink. This is a DIFFICULT policy challenge often called the “fiscal paradox”: during Deficient Demand, the ECONOMY needs MORE government spending to boost AD — but SIMULTANEOUSLY, government TAX REVENUE is FALLING (since lower incomes, lower profits and lower business activity mean less taxable income), making it HARDER for the government to fund the very spending increase needed. This is why governments often resort to DEFICIT FINANCING (borrowing) during downturns rather than relying solely on tax revenue.

Answer: A — Hoarding/speculation is an EFFECT of Excess Demand. Options B, C and D are all CAUSES of Excess Demand (things that push AD above the full-employment AS level). Option A (hoarding and speculation) is instead a CONSEQUENCE/EFFECT of the resulting INFLATION — once prices start rising due to excess demand, people REACT by hoarding goods (anticipating even higher future prices) and engaging in speculative buying, which can further AMPLIFY the inflationary pressure in a self-reinforcing cycle.

Answer: A — Deficient Demand emerges; the multiplier works in reverse. A FALL in Investment (I) directly REDUCES total Aggregate Demand (AD=C+I). If the economy was PREVIOUSLY at full employment, this fall in I will pull AD BELOW the full-employment AS level, creating Deficient Demand. Just as an INCREASE in I triggers a POSITIVE multiplier effect (Chapter 8), a DECREASE in I triggers the SAME multiplier process IN REVERSE — a relatively small fall in I can cause a PROPORTIONALLY LARGER fall in total income and employment, worsening the deficient demand problem.

Answer: A — Excess Demand; raising margin requirement reduces available credit. Recall from Chapter 6: Margin Requirement determines what PORTION of a collateral value banks can lend against. INCREASING this requirement means banks must lend LESS relative to collateral (e.g., forcing borrowers to put up a LARGER share of their own funds), REDUCING the total credit extended to the public. This CONTRACTIONARY effect helps COOL DOWN Excess Demand by shrinking the overall money supply and spending power in the economy.

Answer: A — AD will fall, contributing to Deficient Demand. BOTH changes push AD in the SAME (downward) direction: FALLING EXPORTS means foreigners are buying LESS domestic production, directly reducing a component of AD. RISING IMPORTS means domestic households/firms are spending MORE on FOREIGN goods (money leaving the domestic economy) rather than domestic production. Both effects REDUCE Net Exports (X−M), pulling down total AD and potentially contributing to or worsening Deficient Demand conditions.

Answer: A — They are mirror-image problems with exactly opposite causes, effects and required policy responses. This captures the ENTIRE structural logic of the chapter: EVERYTHING about Excess Demand (its causes like rising C/I/G, its effect of inflation, its need for CONTRACTIONARY policy) has a PRECISE mirror opposite in Deficient Demand (falling C/I/G as causes, unemployment/deflation as effects, EXPANSIONARY policy needed). Real economies commonly CYCLE between these two conditions over time (economic booms creating excess demand risk; recessions creating deficient demand risk), which is exactly WHY governments and central banks continuously monitor and adjust policy.

Answer: A — Excess Demand, since both actions are contractionary. INCREASED public borrowing means the government sells MORE bonds to the public — when people BUY these bonds, they are SETTING ASIDE money (into government securities) INSTEAD of spending it on consumer goods, effectively ABSORBING excess purchasing power from circulation. Combined with REDUCED government spending (directly cutting a component of AD), BOTH actions work TOGETHER as CONTRACTIONARY tools, specifically designed to COOL DOWN Excess Demand/Inflation, not to stimulate a weak economy.

Answer: A — National Income rises (via the multiplier) until S and T rise enough to restore I+G=S+T at a higher income level. When G increases, Injections (I+G) TEMPORARILY exceed Leakages (S+T) at the OLD income level. This imbalance triggers the SAME adjustment mechanism from Chapter 8: unplanned inventory depletion, followed by firms INCREASING production, RAISING National Income (through the multiplier process). As income RISES, BOTH Saving (S, since people save a fraction of higher income, per the Saving Function from Chapter 7) AND Tax revenue (T, since taxes are often linked to income/economic activity) also RISE, until Leakages once again EQUAL Injections — but now at a NEW, HIGHER equilibrium income level.

Answer: C — Both A and R are false. A is FALSE: BOTH Fiscal Policy (Government: spending, taxes, deficit financing) AND Monetary Policy (Central Bank/RBI: Bank Rate, CRR, SLR, Repo Rate, OMO) are used TOGETHER to correct Excess and Deficient Demand — this is one of the CENTRAL themes of this chapter, directly building on Chapter 6’s coverage of RBI credit control tools. R is FALSE: the Central Bank has EXTENSIVE authority to influence AD through controlling money supply and credit availability — this was the ENTIRE focus of the “Controller of Credit” function studied in Chapter 6.

Answer: C — Both A and R are false. A is FALSE: during Deficient Demand, the CORRECT fiscal response is to DECREASE taxes (not raise them), leaving households with MORE disposable income to spend, boosting Consumption and AD. Raising taxes during a demand shortfall would be a POLICY ERROR, further squeezing household spending power. R is FALSE: higher taxes typically REDUCE overall AD, since the resulting FALL in private consumption spending generally OUTWEIGHS any additional government spending capacity — taxes are fundamentally a CONTRACTIONARY tool, appropriate for fighting Excess Demand, NOT Deficient Demand.

Answer: C is incorrectly matched. Increasing Government Expenditure ADDS MORE to Aggregate Demand (recall AD=C+I+G in the three-sector model) — this would make Excess Demand WORSE, not better. To correct EXCESS Demand, the government should DECREASE its expenditure (a contractionary fiscal measure). Increasing government expenditure is instead the CORRECT tool for fighting DEFICIENT Demand (an expansionary measure that boosts weak AD). Options A, B and D are all correctly matched examples of appropriate policy-effect pairings.

Answer: A — The proposal is inappropriate; the scenario describes Excess Demand requiring CONTRACTIONARY policy instead. High inflation combined with an economy near full employment is the CLASSIC signature of EXCESS DEMAND. The CORRECT policy response is CONTRACTIONARY: RAISE interest rates (Bank Rate/Repo Rate) and DECREASE government spending, to REDUCE Aggregate Demand back toward the full-employment AS level, cooling inflation. The policymaker proposal (cut rates, INCREASE spending) is EXACTLY BACKWARDS — these are EXPANSIONARY tools appropriate for DEFICIENT Demand, and applying them here would make the inflation problem WORSE while providing NO employment benefit (since the economy is already near full employment, with no spare capacity to absorb more demand as real output).

Answer: B — Not in equilibrium; Income will RISE since Injections exceed Leakages. Calculate: I+G = 200+150 = Rs 350 crore (Injections). S+T = 180+120 = Rs 300 crore (Leakages). Since Injections (Rs 350 crore) EXCEED Leakages (Rs 300 crore), MORE money is being ADDED to the circular flow than is being WITHDRAWN — this corresponds to AD>AS conditions, causing UNPLANNED inventory depletion, prompting firms to INCREASE production. National Income will RISE (potentially triggering the multiplier process) until a NEW equilibrium is reached where I+G once again equals S+T, at a HIGHER income level.

Answer: B — (I) and (III) are correct; (II) and (IV) are incorrect. (I) CORRECT: since output cannot rise beyond full employment, excess demand translates purely into higher prices. (II) INCORRECT: the measures are DIRECT OPPOSITES — CONTRACTIONARY (raise rates/CRR, cut spending, raise taxes) for Excess Demand versus EXPANSIONARY (lower rates/CRR, raise spending, cut taxes) for Deficient Demand, NOT identical tools. (III) CORRECT: weak demand forces firms to cut production and lay off willing workers, directly causing involuntary unemployment. (IV) INCORRECT: Taxes (T) are a LEAKAGE (withdrawal) from the circular flow, grouped WITH Saving (S) on the leakage side of the equilibrium equation I+G=S+T — NOT an injection like Investment (I) or Government spending (G).
