Macroeconomics for Business 2022 Board Question Paper

Four Assumptions of the Classical Theory of Employment

1. Full Employment Equilibrium: Full employment is the normal state of a capitalist economy; involuntary unemployment is purely temporary.
2. Say’s Law of Markets: “Supply creates its own demand.” Aggregate production automatically generates sufficient purchasing power to buy the output.
3. Wage-Price and Interest Rate Flexibility: Perfect downward and upward flexibility of wages, commodity prices, and interest rates restores market equilibrium automatically.
4. Laissez-Faire Capitalism: Complete freedom from government intervention, where money serves purely as a neutral medium of exchange (Classical Dichotomy).

Derivation of Government Expenditure Multiplier ($K_g$)

In a 3-sector Keynesian closed economy:

$$Y = C + I + G$$

Where consumption function is $C = a + b(Y - T)$, holding investment ($I$) and taxes ($T$) constant:

$$Y = a + bY - bT + I + G$$

$$Y(1 - b) = a - bT + I + G$$

$$Y = \frac{a - bT + I + G}{1 - b}$$

Differentiating with respect to Government Expenditure ($G$):

$$K_g = \frac{\Delta Y}{\Delta G} = \frac{1}{1 - b} = \frac{1}{1 - MPC} = \frac{1}{MPS}$$

• Conclusion: The government spending multiplier equals $\frac{1}{1 - MPC}$ or $\frac{1}{MPS}$.

Four Determinants of the Saving Function

1. Level of Disposable Income ($Y_d$): The primary determinant; saving is a direct positive function of disposable income ($S = -a + sY_d$).
2. Real Interest Rate ($r$): Higher real interest rates increase the return on savings, providing an incentive to substitute future consumption for present consumption.
3. Wealth and Accumulated Assets: Greater accumulated financial and real estate wealth reduces the urgency for additional current saving.
4. Expectations of Future Price and Income Levels: Anticipated future inflation encourages immediate spending, lowering current savings.

Two Major Sources of Deficit Financing

1. Internal (Domestic) Borrowing: Issuing government treasury bills, development bonds, and citizen savings certificates to domestic commercial banks, financial institutions, and the public.
2. Monetization / Central Bank Borrowing: Borrowing directly from the central bank (Nepal Rastra Bank) through overdrafts or issuing new fiat currency, expanding high-powered money.

Four Components of Current Account in Balance of Payments (BOP)

1. Trade in Merchandise Goods (Visible Trade): Receipts from physical exports minus payments for physical imports.
2. Trade in Commercial Services (Invisible Trade): International transactions in tourism, aviation, freight, shipping, and financial services.
3. Primary Income (Factor Income): Cross-border compensation of employees, investment income, dividends, and interest payments.
4. Secondary Income (Current Transfers): Inflows and outflows of workers’ remittances, foreign humanitarian aid, gifts, and grants.

Major Causes of Market Failure

1. Presence of Externalities: Uncompensated spillover costs (negative externalities like industrial pollution) or benefits (positive externalities like basic research).
2. Public Goods: Commodities characterized by non-rivalry in consumption and non-excludability (e.g., national defense, street lighting), leading to the free-rider problem.
3. Market Power and Monopolistic Distortions: Monopolies restrict output below competitive levels to charge higher prices ($P > MC$).
4. Asymmetric Information: Imperfect knowledge leading to adverse selection and moral hazard.

Concept of Macro Dynamic Analysis

Macro dynamic analysis is the study of the behavior of macroeconomic aggregates (national output, aggregate employment, price level, capital accumulation) as they evolve continuously across sequential chronological time.

• Key Characteristic: Explicitly incorporates time lags, rates of change over time ($dY/dt$), adjustment paths, and business cycle fluctuations, tracing the precise trajectory from an initial disequilibrium to a final state.

Determination of National Output in a Four-Sector Economy

In an open four-sector economy (Households, Firms, Government, and Foreign Sector), national output ($Y$) is determined at the equilibrium intersection of Aggregate Demand ($AD$) and Aggregate Supply ($AS$):

$$Y = AD \implies Y = C + I + G + (X - M)$$

• Leakages-Injections Approach:
  $$S + T + M = I + G + X$$
  Where leakages (Saving $S$, Taxes $T$, Imports $M$) exactly balance injections (Investment $I$, Government expenditure $G$, Exports $X$).

Derivation of the IS Curve

The IS curve represents goods market equilibrium where planned investment equals planned saving ($I = S$).

1. Investment Function: $I = I_0 - dr$ (where $d$ is interest sensitivity of investment).
2. Saving Function: $S = -a + (1 - b)Y$ (where $(1 - b) = s$ is MPS).
3. Equilibrium Condition:
   $$-a + sY = I_0 - dr$$
   $$sY = a + I_0 - dr \implies Y = \frac{a + I_0}{s} - \frac{d}{s}r$$

• Slope: Because $d/s > 0$, higher interest rates reduce investment and national output, giving the IS curve a negative (downward) slope in the $(Y, r)$ space.

Three Causes of Demand-Pull Inflation

1. Excessive Growth of Money Supply: When the central bank expands broad money ($M_2$) faster than the growth rate of real GDP, excess purchasing power drives up aggregate prices.
2. Expansionary Fiscal Policy and Budget Deficits: Large increases in public infrastructure spending financed through deficit monetization push aggregate demand beyond full-capacity output.
3. Surge in Export Demand & Remittance Inflows: Massive foreign currency inflows and remittances expand domestic liquidity and consumer consumption expenditure.

Quantitative Instruments of Monetary Policy

Quantitative (general) instruments are monetary policy tools deployed by the central bank (such as Nepal Rastra Bank) to regulate the total volume, cost, and availability of bank credit in the entire macroeconomy without discriminating between specific sectors.

---

Core Quantitative Tools:

1. Cash Reserve Ratio (CRR):

   • The statutory percentage of total customer deposit liabilities that commercial banks are legally mandated to maintain as cash balances with the central bank.
   • Mechanism: Raising CRR locks up bank liquidity, reducing lending capacity and containing inflation; lowering CRR injects credit to stimulate economic activity.

2. Statutory Liquidity Ratio (SLR):

   • The mandatory proportion of deposits that banks must invest in specified liquid unencumbered assets (gold, government treasury bills, development bonds).
   • Ensures banking solvency and directs commercial credit into government sovereign debt.

3. Bank Rate / Policy Repo Rate:

   • The benchmark interest rate at which the central bank lends short-term emergency funds to commercial banks.
   • Increasing policy rates elevates commercial lending rates, deterring speculative borrowing; cutting rates stimulates capital investments.

4. Open Market Operations (OMO):

   • The outright purchase and sale of government securities in the secondary debt market.
   • Selling securities absorbs excess liquidity from the banking system; purchasing securities injects fresh liquidity into circulation.

5. Standing Liquidity Facility (SLF) and Reverse Repo Auctions:

   • Short-term corridor facilities used to stabilize overnight interbank interest rate volatility.

Economic Growth vs. Economic Development

Comparative Analysis

Solution: Consumption Schedule and Keynes’s Psychological Law

i) Completed Schedule ($MPC = 0.8$)

• Since $MPC = \frac{\Delta C}{\Delta Y_d} = 0.8$, each $\Delta Y_d = 100$ increase in income leads to $\Delta C = 0.8 \times 100 = 80$.
• Saving is derived as $S = Y_d - C$:

---

ii) Three Propositions of Keynes’s Psychological Law of Consumption

1. Proposition 1: When Income Increases, Consumption Increases, But by Less:
   • Men are disposed, as a rule, to increase their consumption as income grows, but not by as much as the increase in their income ($0 < \Delta C / \Delta Y < 1$).
   • Here, when $Y_d$ rises by 100, $C$ rises by only 80.
2. Proposition 2: Increased Income is Divided Between Consumption and Saving:
   • The increment in income is shared between spending and saving ($\Delta Y = \Delta C + \Delta S$).
   • For each 100 increase, 80 is spent on consumption and 20 is saved.
3. Proposition 3: An Increase in Income Leads to an Increase in Both Consumption and Saving:
   • A rising national income never leads to a reduction in either absolute consumption or absolute savings; both expand concurrently.

Solution: National Income Accounts Computation

---

(a) Computation of $GDP_{MP}$

1. By Expenditure Method:

$$GDP_{MP} = C + I_g + G + (X - M)$$

• Private Final Consumption Expenditure ($C$) = $\text{Rs } 400\text{ B}$
• Government Consumption Expenditure ($G$) = $\text{Rs } 80\text{ B}$
• Net Exports ($X - M$) = $\text{Rs } (-20)\text{ B}$
• Gross Domestic Capital Formation ($I_g$):
  $$I_g = \text{Net Domestic Fixed Capital Formation} + \text{Depreciation} + \text{Addition to Stocks}$$
  $$I_g = 120 + 80 + (-20) = \mathbf{180\text{ Billion}}$$

$$GDP_{MP} = 400 + 180 + 80 + (-20) = \mathbf{Rs\ 640\text{ Billion}}$$

---

2. By Income Method:

$$GDP_{MP} = NDP_{FC} + \text{Depreciation} + \text{Net Indirect Taxes (NIT)}$$

• Compensation of Employees ($COE$):

  $$COE = \text{Wages and salaries} (200) + \text{Employer social security contribution} (40) = \text{Rs } 240\text{ B}$$

• Operating Surplus: $\text{Rs } 80\text{ B}$ (Rent of 2.0 is already an accounting component of operating surplus)

• Mixed Income of Self-Employed: $\text{Rs } 160\text{ B}$$NDP_{FC} = COE + \text{Operating Surplus} + \text{Mixed Income} = 240 + 80 + 160 = \mathbf{Rs\ 480\text{ Billion}}$$

• Net Indirect Taxes ($NIT$):

  $$NIT = \text{Indirect Taxes} (100) - \text{Subsidies} (20) = \mathbf{Rs\ 80\text{ Billion}}$$

• Consumption of Fixed Capital (Depreciation): $\mathbf{Rs\ 80\text{ Billion}}$$GDP_{MP} = NDP_{FC} + \text{Depreciation} + NIT = 480 + 80 + 80 = \mathbf{Rs\ 640\text{ Billion}}$$

Both expenditure and income methods yield identical results: Rs 640 Billion.

---

(b) Justification: Final Product Method and Double Counting

• Yes, absolutely agreed.
• Justification: The final product method includes only the market value of final consumer and capital goods purchased by end-users, deliberately excluding all intermediate inputs (e.g., wheat sold to a flour mill, or flour sold to a baker). By measuring only the final retail value, it ensures that the value of raw materials is counted exactly once, preventing double counting.

Solution: Saving-Investment Equilibrium and Paradox of Thrift

Given:

• Investment function: $I = 200 + 0.1Y$
• Initial saving function: $S = -400 + 0.2Y$

---

a) Initial Equilibrium Income, Saving, and Investment:

Equilibrium occurs where $S = I$:

$$-400 + 0.2Y = 200 + 0.1Y$$

$$0.2Y - 0.1Y = 200 + 400$$

$$0.1Y = 600 \implies Y^* = \frac{600}{0.1} = \mathbf{Rs\ 6,000\text{ Billion}}$$

• Equilibrium Saving ($S^*$):
  $$S^* = -400 + 0.2(6000) = -400 + 1200 = \mathbf{Rs\ 800\text{ Billion}}$$
• Equilibrium Investment ($I^*$):
  $$I^* = 200 + 0.1(6000) = 200 + 600 = \mathbf{Rs\ 800\text{ Billion}}$$

---

b) Equilibrium When Planned Saving Increases by Rs 100 Billion:

When planned saving shifts upward by Rs 100 Billion, autonomous saving becomes $-400 + 100 = -300$:

$$S' = -300 + 0.2Y$$

Equating new saving with investment ($S' = I$):

$$-300 + 0.2Y = 200 + 0.1Y$$

$$0.1Y = 500 \implies Y' = \frac{500}{0.1} = \mathbf{Rs\ 5,000\text{ Billion}}$$

• New Equilibrium Saving ($S'$):
  $$S' = -300 + 0.2(5000) = -300 + 1000 = \mathbf{Rs\ 700\text{ Billion}}$$
• New Equilibrium Investment ($I'$):
  $$I' = 200 + 0.1(5000) = 200 + 500 = \mathbf{Rs\ 700\text{ Billion}}$$

---

c) Reflection on the Paradox of Thrift:

• Yes, this condition perfectly illustrates the Paradox of Thrift.
• Explanation: An autonomous desire by households to save more (increasing planned saving by Rs 100B) reduces aggregate consumption demand. Because investment is income-induced, the contraction in consumer demand induces a decline in national income from Rs 6,000B to Rs 5,000B. Consequently, the total realized savings actually fell from Rs 800B to Rs 700B rather than rising!

Solution: Nominal GDP, Real GDP, and GDP Deflator

Let 2019 be the base year ($P_0^X = 10, P_0^Y = 20$).

---

a) Computations

1. Nominal GDP (Current Prices $\sum P_t Q_t$):

   • 2019: $(10 \times 1000) + (20 \times 500) = 10,000 + 10,000 = \mathbf{Rs\ 20,000}$
   • 2021: $(30 \times 3000) + (40 \times 1500) = 90,000 + 60,000 = \mathbf{Rs\ 150,000}$
   • 2022: $(20 \times 2000) + (30 \times 1000) = 40,000 + 30,000 = \mathbf{Rs\ 70,000}$

2. Real GDP (Base Year 2019 Prices $\sum P_0 Q_t$):

   • 2019: $(10 \times 1000) + (20 \times 500) = \mathbf{Rs\ 20,000}$
   • 2021: $(10 \times 3000) + (20 \times 1500) = 30,000 + 30,000 = \mathbf{Rs\ 60,000}$
   • 2022: $(10 \times 2000) + (20 \times 1000) = 20,000 + 20,000 = \mathbf{Rs\ 40,000}$

3. GDP Deflator ($\frac{\text{Nominal GDP}}{\text{Real GDP}} \times 100$):

   • 2019: $\frac{20,000}{20,000} \times 100 = \mathbf{100.00}$
   • 2021: $\frac{150,000}{60,000} \times 100 = \mathbf{250.00}$
   • 2022: $\frac{70,000}{40,000} \times 100 = \mathbf{175.00}$

4. Inflation Rate (Percentage Change in GDP Deflator):

   • From 2019 to 2021: $\frac{250 - 100}{100} \times 100 = \mathbf{150\%}$

---

b) Significance of Real GDP in Economic Analysis

1. Measures Actual Physical Production: Removes the distorting effects of price inflation, isolating genuine changes in physical output.
2. Accurate Living Standards Benchmark: Reflects the real availability of goods and services per citizen.
3. Enables Inter-Temporal and International Comparisons: Serves as the authoritative basis for calculating economic growth rates.

Case Study Analysis: Foreign Direct Investment (FDI) Dynamics in Nepal

---

a) Causes for Poor Inflow of FDI in Nepal

1. Political Instability and Frequent Policy Shifts: Chronic government turnover and bureaucratic inconsistencies create high sovereign risk and uncertainty for foreign capital.
2. Bureaucratic Red Tape & Procedural Hurdles: Despite the “One Stop Service” center, multi-agency approvals, delays in profit repatriation, and stringent foreign exchange regulations discourage multinational investors.
3. Inadequate Infrastructure & Land Acquisition Hurdles: Severe transport logistics costs, unreliable power supplies in industrial zones, and prolonged legal disputes surrounding industrial land acquisition.
4. Labor Militancy and Rigid Labor Regulations: Historical labor disputes and rigid employment termination laws raise perceived operating risks.
5. Small Domestic Market and Landlocked Transit Friction: High freight costs through Indian ports undermine export competitiveness.

---

b) Role of FDI in Solving Unemployment and Technological Backwardness

• Yes, absolutely agreed.
• Justification:
  1. Closing the Saving-Investment Gap: Nepal suffers from low domestic capital formation. FDI provides non-debt-creating external capital to fund mega infrastructure (hydroelectric plants, expressways, cement factories).
  2. Direct and Indirect Employment Generation: FDI creates high-skilled engineering, technical, and managerial jobs, while stimulating thousands of downstream indirect jobs across local supplier networks.
  3. Technology Transfer & Spillovers: Multinationals introduce advanced machinery, automated digital control systems, quality benchmarks (ISO), and managerial expertise that local firms adopt through demonstration effects.

---

c) Fiscal Policy Measures to Attract More FDI in Nepal

1. Targeted Corporate Tax Holidays: Provide 10-year complete corporate income tax holidays for investments in prioritized strategic sectors (hydropower, digital IT parks, export manufacturing), followed by concessional tax rates.
2. Customs Duty Waivers on Capital Equipment: Exempt plant machinery, research tools, and spare parts imported for industrial manufacturing from customs duties and VAT.
3. Accelerated Depreciation Allowances: Permit expedited capital depreciation write-offs to enable investors to recover capital expenditure swiftly.
4. Guaranteed Bilateral Double Tax Avoidance Agreements (DTAA): Expand robust DTAA treaties to protect international corporations from double taxation and ensure seamless dividend repatriation.
