Quantity Theory of Money — Milton Friedman's Restatement

Milton Friedman (1956), in his famous essay "The Quantity Theory of Money: A Restatement," revived the classical quantity theory in a modern, choice-theoretic form. He treated the quantity theory not as a rigid mechanical relation but as a theory of the demand for money, and presented it as a body of empirical propositions about the effects of changes in the money stock on prices, output, and employment.

1. Core Idea

The quantity theory, in Friedman's formulation, states that the quantity of money demanded by the public is a stable function of a few variables, and that changes in the nominal quantity of money supplied relative to this demand are the dominant cause of changes in nominal income (prices and output) in the long run.

2. The Demand for Money Function

Friedman applied the theory of consumer choice to money holding. Money is one asset among many in a wealth-holder's portfolio, yielding services (liquidity, convenience) rather than explicit interest. He wrote the demand for real money balances as:

$M^d = f\left(P,\; r_b,\; r_e,\; \frac{1}{P}\frac{dP}{dt},\; w,\; Y,\; u\right)$

where:

• $M^d$ = nominal demand for money
• $P$ = general price level
• $r_b$ = expected nominal return on bonds
• $r_e$ = expected nominal return on equities
• $\frac{1}{P}\frac{dP}{dt}$ = expected rate of inflation (return on holding goods)
• $w$ = ratio of non-human to human wealth
• $Y$ = permanent (expected long-run) income
• $u$ = taste/preference variables

Because the function is homogeneous of degree one in P and Y, it can be rewritten in real terms:

$\frac{M^d}{P} = f\left(r_b,\; r_e,\; \frac{1}{P}\frac{dP}{dt},\; w,\; y_p,\; u\right)$

where $y_p = Y/P$ is real permanent income. This shows that real money demand depends on real variables, not on the nominal money stock — the essence of the classical neutrality proposition.

3. The Quantity Equation Restated

Friedman expressed the theory in the form of the exchange equation:

$M V = P Y$

where $V$ is the income velocity of circulation. Since $M^d/P$ is a stable function of real variables, velocity $V = PY/M$ is also stable and predictable in the long run. Rearranging:

$P = \frac{M V}{Y}$

Thus, given stable $V$ and full-employment output $Y$, changes in M translate proportionally into changes in P — the classical conclusion, but now derived from a micro-founded demand for money.

4. Key Propositions of Friedman's Theory

1. Stability of money demand: The demand for real balances is a stable function of permanent income and expected rates of return. Permanent income, not current income, is the appropriate scale variable.
2. Velocity is stable (not constant): Unlike Fisher's fixed $V$, Friedman allowed $V$ to vary with interest rates and expected inflation, but held it to be a predictable function of these variables.
3. Money is the dominant cause: Changes in nominal income are primarily caused by changes in the nominal money supply, not by autonomous changes in velocity or spending.
4. Short-run vs long-run effects:
   • In the short run, an increase in $M$ raises real output and employment (because prices and wages are sticky and expectations adjust slowly).
   • In the long run, output returns to its natural level and the entire effect falls on the price level — money is neutral.
5. Transmission mechanism: Changes in $M$ affect spending through portfolio adjustment — an excess money balance is used to buy bonds, equities, and goods, lowering interest rates and raising wealth and consumption.

5. Policy Implications

• Monetary rule over discretion: Since money supply changes have powerful and lagged effects, Friedman advocated a fixed growth rule (e.g., $k$ percent per year, roughly equal to the long-run growth of real output) rather than activist counter-cyclical policy.
• Inflation is always and everywhere a monetary phenomenon: Sustained inflation results from excessive growth of the money stock.
• Rejection of Keynesian fine-tuning: Fiscal policy is crowded out; monetary policy should aim at price stability, not at pegging interest rates or unemployment.

6. Criticisms

• The assumed stability of money demand broke down after the 1970s with financial innovation and deregulation, weakening the link between $M$ and $PY$.
• Velocity proved unstable in the short run, undermining the case for a rigid monetary rule.
• The theory downplays the role of expectations, uncertainty, and institutional factors in the transmission mechanism.
• Empirical evidence shows that money–income causality is not always unidirectional; income can also cause money.

Conclusion

Friedman's quantity theory restates the classical doctrine in a rigorous, choice-theoretic framework: money demand is a stable function of permanent income and opportunity-cost variables, velocity is predictable, and monetary changes are the principal determinant of nominal income. While its strong empirical claims have been challenged, it remains the foundation of monetarist thought and of modern rules-based monetary policy.

Phillips Curve and the Samuelson-Solow Modification

1. The original Phillips curve (A. W. Phillips, 1958)

Phillips studied about 100 years of British data (1861-1957) and found a stable inverse relationship between the unemployment rate and the rate of change of money wages:

$\dot{W} = f(U), \qquad \frac{\partial \dot{W}}{\partial U} < 0$

where $\dot{W}$ is the percentage change in money wages and $U$ the unemployment rate. The curve is convex to the origin: wage inflation rises at an increasing rate as unemployment falls, because near full employment firms must bid ever higher wages for scarce labour. Two implications follow:

• There is a trade-off between unemployment and wage inflation.
• There is a critical unemployment rate at which money wages are stable ($\dot{W}=0$).

2. Samuelson-Solow modification (1960)

In "Analytical Aspects of Anti-Inflation Policy" (American Economic Review, 1960), Samuelson and Solow adapted Phillips' wage curve to the United States and turned it into a policy tool.

(a) From wage inflation to price inflation. With prices set as a markup over unit labour cost, $P=(1+z)\,W/A$, where $A$ is average labour productivity. In growth rates:

$\pi = \dot{W} - \dot{A}$

Price inflation equals wage inflation minus productivity growth. Since $\dot W$ depends negatively on $U$, so does $\pi$: $\pi = g(U)$, $g'<0$. The curve now relates price inflation to unemployment.

(b) A menu of policy choices. They presented the curve as a menu from which policymakers could choose a combination of inflation and unemployment: lower unemployment at the cost of higher inflation, or lower inflation at the cost of higher unemployment.

(c) Empirical estimates for the USA. From US data they estimated that price stability would require unemployment of about 5.5-6%, while holding unemployment down to about 3% would bring inflation of roughly 4-5% a year. They also warned that the curve could shift with institutional factors such as union power, markups and expectations, so the trade-off was not permanent.

(d) Policy implication. Full employment and reasonable price stability could not both be achieved fully; the best point on the curve was a matter of social choice, to be reached through fiscal and monetary demand management.

3. Significance and criticism

The Samuelson-Solow version dominated the 1960s and underpinned Keynesian "fine-tuning". Friedman and Phelps (1968) criticised it for ignoring expectations: once workers anticipate inflation, the curve shifts upward and the trade-off disappears in the long run, leaving only the natural rate of unemployment (a vertical long-run Phillips curve). The stagflation of the 1970s, with high inflation and high unemployment together, confirmed this critique.

Monetary Approach to the Balance of Payments

The monetary approach to the balance of payments is a theory associated with the Chicago School, developed mainly by Harry Johnson, Robert Mundell, and Jacob Frenkel in the 1960s–70s. It treats the balance of payments as essentially a monetary phenomenon rather than a real or trade phenomenon. The central claim is that a balance of payments deficit or surplus reflects an imbalance between the demand for money and the supply of money in an open economy.

1. Core Idea

Under a fixed exchange rate system, the money supply of a country is not fully controlled by its central bank, because changes in international reserves (through balance of payments surpluses or deficits) also change the money supply. Therefore:

• A BOP deficit = excess supply of money (money supply > money demand) → reserves flow out.
• A BOP surplus = excess demand for money (money demand > money supply) → reserves flow in.

The balance of payments is thus the adjustment mechanism that brings money supply in line with money demand.

2. The Basic Model

Money demand is specified as a stable function of real income and the price level:

$M_d = k \cdot P \cdot Y$

where:

• $M_d$ = nominal demand for money
• $P$ = domestic price level
• $Y$ = real output (income)
• $k$ = fraction of income held as money (assumed stable)

Money supply is:

$M_s = m \cdot (D + R)$

where:

• $D$ = domestic credit created by the central bank
• $R$ = foreign exchange reserves
• $m$ = money multiplier

Equilibrium condition: $M_s = M_d$

$m(D + R) = kPY$

Solving for reserves:

$R = \frac{kPY}{m} - D$

This is the key equation. It shows that changes in reserves (i.e., the BOP) depend on:

• changes in money demand ($kPY$), and
• changes in domestic credit ($D$).

3. Main Propositions

1. BOP deficits are monetary in nature. They arise when domestic credit expansion exceeds the growth of money demand.
2. A deficit is self-correcting. As reserves fall, the money supply falls, reducing excess balances until $M_s = M_d$ and the deficit disappears.
3. Devaluation works only through the money market. A devaluation raises the domestic price level, increases money demand, and thereby improves the BOP — but only if it is not accompanied by offsetting domestic credit expansion.
4. Sterilization is ineffective in the long run. If the central bank tries to offset reserve losses by expanding domestic credit, the deficit simply continues.
5. BOP is a monetary, not a real, problem. Real factors (income, tastes, technology) matter only through their effect on money demand.

4. Mechanism of Adjustment

Suppose the central bank expands domestic credit ($D \uparrow$). Then:

$M_s > M_d \Rightarrow \text{excess money balances}$

Households spend the excess on goods, services, and foreign assets → imports rise, capital outflows occur → BOP deficit → reserves fall → $M_s$ falls → excess balances eliminated → BOP returns to equilibrium.

The opposite happens with a credit contraction: excess money demand → reserve inflows → BOP surplus.

5. Policy Implications

• Monetary policy is the key tool for correcting BOP imbalances. Reducing domestic credit improves the BOP.
• Fiscal policy affects BOP only indirectly, through its impact on money demand and the budget deficit financed by credit creation.
• Under flexible exchange rates, the exchange rate adjusts instead of reserves, so the monetary approach predicts that BOP imbalances disappear and the exchange rate bears the adjustment burden.
• Global monetarism: In a fixed-rate world, a single world money supply and world inflation rate exist; individual countries cannot independently control their money supply in the long run.

6. Criticisms

1. Assumes stable money demand function, which is questionable, especially in developing countries.
2. Ignores real factors such as productivity, tastes, and structural changes that affect trade.
3. Assumes full employment and price flexibility, which may not hold in the short run.
4. Overlooks the role of capital mobility and speculative flows.
5. Empirical evidence is mixed; many BOP crises cannot be explained by monetary factors alone.
6. Not applicable to developing countries where financial markets are underdeveloped and money demand is unstable.

7. Conclusion

The monetary approach provides a powerful and elegant framework for understanding the balance of payments as a stock-flow adjustment process in the money market. It correctly emphasizes that sustained BOP deficits are usually associated with excessive domestic credit expansion. However, its assumptions of stable money demand and price flexibility limit its applicability, particularly in developing economies like Nepal. It is best regarded as a complement to, rather than a substitute for, the elasticity and absorption approaches.

Money is anything generally accepted as a medium of exchange and a measure of value. In a modern economy it performs several functions, which are broadly classified into primary, secondary and contingent functions.

Primary functions

1. Medium of exchange — Money is accepted by all as payment for goods, services and debts. This eliminates the double coincidence of wants required under the barter system and makes transactions smooth and quick.
2. Measure of value (unit of account) — Money serves as a common denominator in which the value of all goods and services is expressed and compared. Prices, wages, rents and profits are all quoted in money, which simplifies valuation and accounting.

Secondary functions

3. Store of value — Money can be saved for future use because it is durable, portable and generally retains value. It transfers purchasing power from the present to the future, though inflation erodes this function.
4. Standard of deferred payment — Money is used to settle debts and contracts payable in the future. Loans, instalments and salaries are fixed in money terms, which makes borrowing and lending possible and encourages credit and capital formation.
5. Transfer of value — Money allows purchasing power to be transferred from one person to another or from one place to another easily, as through cheques, drafts and remittances.

Contingent functions

6. Distribution of national income — Money is the means by which factor incomes (wages, rent, interest, profit) are paid and the national product is distributed among factors of production.
7. Basis of credit — Modern banking and credit creation rest on money; banks create credit on the foundation of money deposits.
8. Maximisation of satisfaction — Consumers can allocate money income among different goods to maximise utility, and producers can combine factors to minimise cost.
9. Liquidity and general purchasing power — Money is the most liquid asset, holding general command over goods and services.

Thus, money is not merely a medium of exchange; it acts as a unit of account, a store of value, a standard of deferred payment and the basis of credit and income distribution. By removing the difficulties of barter, it promotes specialisation, trade, saving, investment and economic growth, and in this sense it truly performs various functions in an economy.

Real Balance Effect — Don Patinkin (5 marks)

Meaning. The real balance effect (also called the Pigou–Patinkin effect) is the influence of a change in the real value of people's money holdings on their consumption spending. Don Patinkin gave it a central place in his Money, Interest, and Prices (1956) to show how a general fall in prices can raise aggregate demand and restore full employment.

Real balance defined. Real balance means the purchasing power of nominal money balances, i.e. $M/P$ where $M$ is the nominal stock of money and $P$ is the price level. When prices fall with nominal money unchanged, $M/P$ rises, so wealth rises.

How the effect works.

1. Suppose there is unemployment and prices fall.
2. The real value of cash holdings ($M/P$) increases, so households feel wealthier.
3. Being wealthier, they consume more out of given income.
4. Aggregate demand rises, output and employment increase, and the economy moves back toward full employment.

Patinkin's integration of money and value theory. Patinkin argued that money is not merely a medium of exchange but also a store of value, and hence a component of real wealth. He therefore wrote the consumption function as depending on real income and real balances: $C = f(Y,\; M/P)$ This is his "real balance effect" proper. It is the link that makes money non-neutral: a change in $M$ or $P$ alters real wealth and thus real variables.

Conditions for its strength.

• Money must be outside money (fiat or government-issued), not backed by private debt, so that a fall in $P$ genuinely raises net private wealth.
• The distribution of money holdings must be such that those gaining real balances actually spend.
• Expectations must not be perverse; if falling prices create expectations of further falls, spending may be postponed and the effect weakened.

Significance.

1. It provides the automatic stabiliser that classical economists claimed: flexible prices can, in principle, bring the economy to full employment without government intervention.

• It shows why a deflationary gap cannot persist indefinitely in Patinkin's system.

2. It demonstrates that the quantity theory holds only when the real balance effect is absent or negligible.
3. It reconciles monetary theory with general equilibrium value theory — Patinkin's main contribution.

Criticism.

• Keynesians (and later Patinkin himself) held that the effect is too weak and slow to cure a depression; hence fiscal policy is still needed.
• It works only with outside money; in a credit-money economy its size is small.
• It ignores distribution effects and expectational effects, which may offset it.

Conclusion. The real balance effect is Patinkin's key device for showing that money matters for real variables through wealth. It gives a theoretical automatic adjustment mechanism, but its practical importance in fighting deep depressions is limited.

Balance of payments is always balanced in accounting sense. Why? [5 marks]

Answer:

The balance of payments (BoP) of a country is always balanced in the accounting (bookkeeping) sense because it is prepared on the double-entry system of accounting. Under this system, every international transaction is recorded twice — once as a credit and once as a debit — so the total of all credits must always equal the total of all debits. Hence, the BoP always "balances" as an accounting statement.

Reasons:

1. Double-entry bookkeeping: Every transaction has two sides. For example, if Nepal imports goods worth Rs 1,00,000 on credit, the import is debited in the current account and the corresponding liability (short-term foreign borrowing) is credited in the capital account. The two entries offset each other, keeping the account balanced.

2. Corresponding entries for every item: Every deficit or surplus item automatically creates its own financing item. A trade deficit must be financed by borrowing from abroad, drawing down reserves, or receiving grants/remittances — all of which appear as credit entries. Thus the deficit in one sub-account is matched by a surplus in another.

3. Reserve account as the balancing item: The country's official reserve account (foreign exchange reserves) acts as the residual or balancing item. Any net deficit is met by a fall in reserves (credit entry), and any net surplus leads to an increase in reserves (debit entry). This ensures the overall account always balances.

4. Statistical discrepancy/errors and omissions: In practice, due to recording errors, timing differences and unrecorded transactions, the two sides may not match exactly. A separate item called "errors and omissions" (or net errors and omissions) is inserted to make the account balance. This further ensures the identity holds.

Conclusion:

The BoP is always balanced in the accounting sense because of the double-entry system and the use of the reserve account and errors-and-omissions as balancing items. However, it may be in economic disequilibrium — that is, it may show a deficit or surplus in its individual components (like the current account), which is what matters for policy. Thus, "always balanced" refers only to its bookkeeping identity, not to its economic balance.

Demand-pull vs Cost-push inflation

Conclusion: Demand-pull inflation originates from the demand side and is associated with expansion, whereas cost-push inflation originates from the supply side and is associated with stagnation plus inflation (stagflation). Hence the policy remedies also differ — demand management for the former, supply-side measures for the latter.

Major instruments of monetary policy in Nepal

Nepal Rastra Bank (NRB) is the central bank. Its main aims are price stability, a stable exchange rate (the Nepali rupee is pegged to the Indian rupee) and adequate liquidity for growth. It uses the following instruments.

A. Quantitative (general) instruments

• Cash Reserve Ratio (CRR): the minimum share of deposits that banks and financial institutions must hold as cash with NRB. Raising it reduces lending capacity; lowering it releases liquidity.
• Statutory Liquidity Ratio (SLR): the minimum share of liabilities that banks must hold in liquid assets such as cash, government securities and balances with NRB.
• Bank rate: the rate at which NRB lends to commercial banks. It signals the stance of policy and sets the ceiling of the interest rate corridor.
• Open market operations (OMO): NRB buys or sells government securities and uses reverse repo, repo and deposit collection auctions to absorb or inject liquidity. These are the main day-to-day tools.
• Interest rate corridor: a policy rate bounded by a ceiling (the standing liquidity facility or bank rate) and a floor (the deposit collection rate) to keep the short-term interbank rate stable.
• Refinance facility: concessional lending through banks to priority sectors such as agriculture, small and cottage industries and export-oriented activity.

B. Qualitative (selective) instruments

• Directed lending: requiring banks to lend minimum shares to productive, agriculture, energy and deprived sectors.
• Margin requirements and loan-to-value limits: for example on loans against shares or real estate.
• Moral suasion: NRB persuades banks through directives and discussions.

Nepalese context. Because of the peg with the Indian rupee, NRB cannot set interest rates fully independently, and it must guard its foreign exchange reserves. It therefore relies mainly on CRR, SLR, OMO and the interest rate corridor to manage liquidity and keep inflation in line with India's.

Tobin's Portfolio Selection Approach to Money Demand (5 marks)

Background: Tobin (1958) extended Keynes's liquidity preference theory by explaining why rational, risk-averse individuals hold both money and bonds rather than putting all wealth into the higher-yielding asset. His approach is based on the trade-off between risk and return.

Assumptions:

1. Wealth holders hold a portfolio of only two assets: money and bonds.
2. Money is a riskless asset with zero (or certain) nominal return.
3. Bonds yield a positive expected return but carry capital gain/loss risk (interest rate uncertainty).
4. Individuals are risk-averse and maximize expected utility.

Core idea: Since bonds are risky, a risk-averse person diversifies — holding some money (safe but zero return) and some bonds (risky but positive return). The optimal proportion depends on the expected return on bonds and the degree of risk aversion.

Derivation logic:

• Let the share of wealth in bonds be $b$ and in money be $(1-b)$.
• Expected portfolio return: $E(R) = b \cdot r_b$ (where $r_b$ is bond yield).
• Portfolio risk (standard deviation): $\sigma_R = b \cdot \sigma_b$.
• As $b$ rises, both expected return and risk rise proportionally. The individual maximizes utility subject to this risk–return constraint, giving an optimal $b^*$ and hence an optimal money holding $M^d = (1-b^*)W$.

Determinants of money demand:

1. Interest rate ($r$): A rise in $r$ raises the reward for holding bonds, so $b^*$ rises and money demand falls — same inverse relation as Keynes, but derived from risk aversion, not just transactions/speculation.
2. Wealth ($W$): Higher wealth raises absolute money demand.
3. Riskiness of bonds ($\sigma_b$): Greater uncertainty lowers bond holding and raises money demand.
4. Degree of risk aversion: More risk-averse individuals hold more money.

Significance: Tobin provided microeconomic foundations for the speculative demand for money, showing that diversification — not an "all-or-nothing" choice — explains why people hold money even when bonds yield more. This makes money demand interest-elastic and more stable, strengthening the case for monetary policy.

McKinnon's Demand for Money Function [5 marks]

Ronald I. McKinnon, in his work on financial repression and economic development (1973), proposed a demand for money function that differs from the conventional Keynesian and Friedmanite formulations by emphasizing the role of financial deepening and the degree of monetization in developing economies. His function is particularly relevant for less developed countries (LDCs) where the financial system is fragmented and the subsistence (non-monetized) sector coexists with the monetized sector.

The Function

McKinnon's demand for money function is expressed as:

$\left(\frac{M}{P}\right)^d = f\left(Y,\ \frac{I}{Y},\ r_m - \pi^e,\ \dots\right)$

More specifically, in McKinnon's formulation:

$\left(\frac{M}{P}\right)^d = L\left(Y,\ \frac{I}{Y},\ d - \pi^e\right)$

where:

• $\left(\frac{M}{P}\right)^d$ = desired real money balances
• $Y$ = real income (output)
• $\frac{I}{Y}$ = ratio of investment to income (a proxy for the degree of monetization and capital accumulation)
• $d$ = nominal deposit rate of interest paid on money
• $\pi^e$ = expected rate of inflation
• $d - \pi^e$ = real return on holding money

Key Features

1. Wealth and Monetization Effect: Unlike Friedman, who uses permanent income and wealth, McKinnon uses $Y$ and $\frac{I}{Y}$. The variable $\frac{I}{Y}$ captures the process of capital accumulation and the spread of the money economy. As an economy develops and monetizes, the demand for money rises.

2. Real Rate of Return on Money: The opportunity cost of holding money is measured by the real deposit rate $(d - \pi^e)$. McKinnon argues that in LDCs, the relevant substitution is not between money and bonds (as in Keynes) but between money and physical capital (self-financed investment). Hence, the real return on money matters greatly.

3. Complementarity between Money and Capital: A key McKinnon insight is that money and capital are complementary, not substitutes, in developing economies. Higher real deposit rates encourage saving in the form of bank deposits, which are then intermediated into investment. Thus, a higher $(d - \pi^e)$ raises both real money demand and capital formation — the McKinnon complementarity hypothesis.

4. Financial Repression: When governments keep nominal deposit rates artificially low (below the inflation rate), real returns become negative, reducing money demand and driving savings into unproductive assets (gold, land, foreign currency). This is "financial repression," which McKinnon argues retards investment and growth.

Policy Implication

McKinnon recommends financial liberalization — raising deposit rates to positive real levels — to increase real money demand, mobilize savings, and promote investment. This contrasts with Keynesian prescriptions of low interest rates to stimulate investment.

The monetary base model of money multiplier explains how the total money supply in an economy is determined by the monetary base (also called high-powered money or reserve money) and the money multiplier. It is expressed as:

$M = m \times B$

where:

• $M$ = total money supply
• $m$ = money multiplier
• $B$ = monetary base (high-powered money)

1. Monetary Base (B)

The monetary base consists of currency held by the public ($C$) plus reserves held by commercial banks with the central bank ($R$):

$B = C + R$

It is called "high-powered money" because every unit of it can support multiple units of money supply through the credit creation process.

2. Derivation of the Money Multiplier

Total money supply is defined as currency with the public plus demand deposits:

$M = C + D$

Let:

• $c = \dfrac{C}{D}$ = currency–deposit ratio
• $r = \dfrac{R}{D}$ = reserve–deposit ratio

Then: $B = C + R = cD + rD = (c + r)D$

$M = C + D = cD + D = (1 + c)D$

Dividing $M$ by $B$:

$\frac{M}{B} = \frac{(1+c)D}{(c+r)D} = \frac{1+c}{c+r}$

Thus the money multiplier is:

$m = \frac{1+c}{c+r}$

3. Interpretation

• The multiplier $m$ is greater than 1 because $c + r < 1 + c$ (since $r < 1$).
• A higher currency–deposit ratio ($c$) lowers the multiplier, as more base money is held as currency outside banks.
• A higher reserve–deposit ratio ($r$) also lowers the multiplier, as banks create fewer deposits per unit of reserves.
• The central bank controls $B$ directly, while $c$ and $r$ depend on public behaviour and bank policy.

4. Conclusion

The monetary base model shows that changes in money supply arise from changes in the monetary base and the multiplier. The central bank can influence money supply by altering $B$ (through open market operations, discount policy, etc.), but the ultimate effect depends on the behaviour of the public and commercial banks as reflected in $c$ and $r$.

Major causes of inflation in Nepal

1. Import-dependence and supply shocks: Nepal imports a large share of consumer goods, petroleum products and industrial raw materials. A rise in world prices or depreciation of the Nepali rupee against the US dollar directly raises domestic costs (imported/cost-push inflation). Disruption of supplies from India through strikes, blockades or border closures causes acute shortages and price spikes.

2. Excessive growth of money supply: Remittance inflows, expansionary credit from banks and deficit financing by the government increase purchasing power faster than the supply of goods, creating demand-pull pressure. In FY 2021/22, inflation crossed 7 per cent largely due to high money supply growth and import price hikes.

3. Rising cost of production: Frequent increases in petroleum prices, electricity tariffs, transport costs, wages and agricultural input prices raise the cost of production, which producers pass on to consumers.

4. Structural bottlenecks: Low agricultural productivity, weak infrastructure, poor market integration, middlemen and syndicate practices, and supply bottlenecks (bandhs, strikes, cartelling) restrict supply and push up prices.

5. Depreciation of the rupee and global factors: The Nepali rupee is pegged to the Indian rupee; when the Indian rupee weakens against the dollar, Nepal's import bill rises. Global events such as the COVID-19 pandemic and the Russia–Ukraine war raised fuel and food prices worldwide, transmitting inflation to Nepal.

6. Ineffective monetary and fiscal management: Delayed and uncoordinated policy responses, high government borrowing and weak market monitoring allow inflationary pressures to persist.

Measures to control inflation

1. Monetary measures: Nepal Rastra Bank should tighten credit (raise bank rate, CRR, and margin requirements), mop up excess liquidity through open market operations, and use moral suasion to restrain unproductive lending.

2. Fiscal measures: Reduce unnecessary government expenditure, control deficit financing, rationalise taxes, and increase capital spending to expand productive capacity.

3. Supply-side measures: Boost domestic production, especially agriculture, through irrigation, fertiliser subsidy, seeds and extension services; develop hydropower and industries to substitute imports.

4. Trade and import management: Reduce import dependence, promote export-oriented production, and use selective import duties and quotas on luxury goods.

5. Price control and market regulation: Strengthen market monitoring, break syndicates and cartels, maintain buffer stocks of essential goods, and enforce the Consumer Protection Act strictly.

6. Income and wage policy: Link wage increases to productivity growth and avoid excessive wage hikes that feed cost-push inflation.

7. Structural reforms: Improve infrastructure, transport and market access; promote financial inclusion and digital payments to reduce transaction costs.

In short, Nepal's inflation is mainly imported and cost-push in nature, aggravated by remittance-driven demand. A coordinated mix of tight monetary policy, prudent fiscal management, supply-side expansion and strict market regulation is needed to keep inflation within the target of about 5–6 per cent.

Income and interest rate effects of improving the position of BoP (5 marks)

An improvement in the balance of payments (BoP) position — say, through an increase in exports or a fall in imports — affects the economy through the foreign trade multiplier (income effect) and through money market adjustment (interest rate effect). These are the two central transmission channels in the Mundell–Fleming/open-economy IS–LM framework.

1. Income effect

• A BoP improvement raises net exports (NX ↑), which raises aggregate demand and hence equilibrium national income: $Y = C + I + G + (X - M)$.
• Through the foreign trade multiplier, $k = \dfrac{1}{1 - c(1-t) + m}$, the initial rise in exports produces a multiplied rise in income.
• The rise in income, however, raises imports (since $M = M_0 + mY$), which partly offsets the initial improvement in the trade balance. The BoP therefore improves by less than the initial export increase — the income effect works against the initial BoP gain.
• Higher income also raises saving and tax revenue, and stimulates employment and output.

2. Interest rate effect

• Higher income raises transaction demand for money ($L_t = kY$), so with a fixed money supply the interest rate rises (money market equilibrium: $M/P = kY - hi$).
• The higher interest rate crowds out some private investment and consumption, moderating the income expansion.
• On the external side, a higher domestic interest rate attracts foreign capital inflows (hot money), improving the capital/financial account of the BoP and appreciating the exchange rate under floating rates.
• The appreciation makes exports dearer and imports cheaper, which worsens the trade balance — again partly offsetting the original BoP improvement.

Conclusion

An improvement in the BoP thus has a dual effect: it raises income (through the trade multiplier) and raises the interest rate (through the money market). Both induced changes — higher imports and exchange rate appreciation — feed back to reduce the size of the initial BoP surplus. The net outcome depends on the relative strengths of the marginal propensity to import, the interest sensitivity of capital flows, and the exchange rate regime.
