Mark scheme · ECO.MAC14 The Monetary Policy Transmission Mechanism and Its Evaluation

Question 1

B1 selecting B, the interest rate channel, which directly reduces market interest rates on mortgages and consumer loans when Bank Rate is cut
Answer: B

Question 2

B1 a monetary policy action that raises asset prices such as equities, bonds and house prices
B1 higher asset prices increase household wealth and collateral values, encouraging consumption and enabling more lending for investment, thereby raising aggregate demand
Answer: Higher monetary stimulus raises asset prices, which increases wealth and collateral values and so boosts consumption and investment, increasing AD.

Question 3

M1 Bank Rate cut puts downward pressure on market interest rates for mortgages, credit cards and personal loans
A1 lower interest payments increase disposable income for households with variable-rate debt and reduce the cost of new borrowing
A1 higher disposable income and cheaper credit raise consumption, shifting aggregate demand to the right
Answer: A lower Bank Rate reduces market interest rates, lowering mortgage and loan payments and making borrowing cheaper; households therefore have higher effective disposable income and face cheaper credit, which increases consumption and shifts AD rightwards.

Question 4

B1 axes are correctly labelled Price level (vertical) and Real GDP (horizontal)
B1 initial equilibrium labelled E1 with an intersection of AD1 and SRAS at PL1 and Y1
B1 AD curve is drawn shifted to the right and labelled AD2
B1 new equilibrium labelled E2 with PL2 and Y2 clearly shown
M1 states that a Bank Rate cut reduces interest rates, encouraging C and I, can raise asset prices and may depreciate the exchange rate
A1 links the rise in C and I (and possibly net exports and asset-driven consumption) to a rightward shift of AD (AD1 to AD2)
A1 identifies the result: higher real GDP (Y2>Y1) and a higher price level (PL2>PL1) given SRAS unchanged
B1 diagram and explanation are coherent, showing the causal chain from interest rate cut to AD shift and higher price level

Question 5

M1 Bank Rate cut reduces the cost of borrowing and lowers yields on safe assets, reducing firms' cost of capital
A1 a lower cost of capital makes more investment projects have expected returns exceeding financing costs, so firms undertake more investment
A1 higher investment increases aggregate demand directly and also raises future productive capacity
Answer: A Bank Rate cut lowers borrowing costs and yields, reducing firms' cost of capital. More investment projects become profitable, so firms increase investment spending, raising AD now and increasing future capacity.

Question 6

M1 lower interest rates tend to reduce inflows of capital seeking higher returns and can make sterling less attractive, causing a depreciation of the exchange rate
A1 a depreciation makes exports cheaper to foreign buyers and imports more expensive to domestic buyers, tending to increase export volumes and reduce import volumes
A1 the net exports component (X-M) improves, raising aggregate demand
Answer: A Bank Rate cut often depreciates the exchange rate by reducing capital inflows, making exports cheaper and imports more expensive; this tends to raise net exports and so increases AD.

Question 7

M1 a Bank Rate cut can raise consumer and business confidence by signalling easier financial conditions and by reducing the chance of unemployment rising
A1 higher confidence increases the propensity to spend now rather than save, and encourages firms to invest and hire
A1 this behavioural response amplifies the impact of the interest rate cut on AD beyond the mechanical effect of lower borrowing costs
Answer: A cut in Bank Rate can boost consumer and business confidence, making households more willing to spend and firms more willing to invest, which amplifies the rightward shift in AD beyond purely mechanical interest-rate effects.

Question 8

M1 QE involves central bank purchases of long-term assets which raises their prices and lowers yields, prompting investors to rebalance into riskier assets and equities
A1 higher asset prices boost wealth and collateral, and lower yields reduce firms' and households' cost of borrowing, increasing consumption and investment and thus shifting AD to the right
A1 additionally, by increasing bank reserves QE can encourage banks to expand lending if they choose to, further supporting AD
Answer: QE raises asset prices and lowers long-term yields, causing portfolio rebalancing into riskier assets, increasing wealth and lowering financing costs, which boosts consumption and investment and so increases AD. QE may also raise bank reserves and support lending if banks expand credit.

Question 9

M1 identifies a reason QE can work at the zero lower bound, e.g. by lowering long-term yields and raising asset prices when short rates cannot be cut further
A1 develops this point: lower long yields and higher asset prices can raise consumption and investment and support AD even when Bank Rate is at zero
M1 identifies a limitation, e.g. if banks hoard reserves or if the portfolio rebalancing effect is weak, the pass-through to lending, asset prices and real activity may be muted
A1 brief judgement: QE can be a useful tool at the zero lower bound but its effectiveness depends on behavioural responses by banks, investors and households and so is not guaranteed
Answer: QE can be effective at the zero lower bound by lowering long-term yields and raising asset prices, supporting AD; however its impact is uncertain if banks do not lend or investors do not rebalance, so it is a useful but not foolproof tool.

Question 10

B1 a liquidity trap occurs when interest rates are at or near zero and households and firms prefer to hold cash rather than invest or spend, making conventional monetary policy ineffective
B1 relevance: in a liquidity trap, cuts in Bank Rate have little effect on spending because the demand for money is highly elastic and the normal channels of interest-rate transmission are impaired
Answer: A liquidity trap is when interest rates are at or near zero and people prefer holding cash, reducing the effectiveness of Bank Rate cuts because monetary transmission into spending and investment is weak.

Question 11

M1 identifies that there are recognition, decision and implementation lags plus long transmission and impact lags before policy affects output
A1 explains that because lags are long and uncertain, monetary policy may take effect after the output gap has partly or fully closed, potentially destabilising the economy or causing inflation later
A1 adds that variable lag length makes it hard to calibrate policy size and timing, weakening confidence that policy will reliably close a given negative output gap
Answer: Monetary policy faces long recognition, decision and transmission lags so its effects on output are delayed and uncertain; this means policy may act too late or overshoot, limiting its reliability in closing a negative output gap.

Question 12

M1 identifies that households or firms with high debt or low collateral may be unwilling or unable to borrow even when rates fall
A1 explains that lenders may be unwilling to extend credit to weak-balance-sheet borrowers, so lower rates do not translate into higher lending and spending
A1 consequence: monetary policy stimulus is blunted, reducing its capacity to raise AD and close a negative output gap
Answer: If households or firms are highly indebted or lack collateral, they may not borrow more when rates fall, and banks may restrict credit; this weakens the link from rate cuts to consumption and investment so monetary policy has smaller effects on AD.

Question 13

Level 1 (1-5): Basic statements about how monetary policy can affect demand, with limited linkage between channels and the negative output gap and little or no evaluation or use of AD/AS. Points are fragmentary or descriptive.
Level 2 (6-10): Clear explanation of several transmission channels and how they can work to close a negative output gap, with some use of AD/AS. Some evaluation of limits such as lags, liquidity traps and balance-sheet issues, but analysis may be partially developed or unbalanced.
Level 3 (11-15): Detailed, well-balanced analysis weighing strengths and weaknesses of monetary policy in closing a negative output gap. Considers multiple channels, the role and limits of QE at low rates, time lags, confidence effects and distributional or supply-side considerations. Uses AD/AS to show short-run effects and discusses secondary effects and real-world constraints, leading to a supported and nuanced judgement.
Indicative content:
- Explanation of how Bank Rate cuts affect consumption via lower mortgage and loan payments and cheaper borrowing, shifting AD right; use AD/AS to show higher Y and higher PL in short run.
- Discussion of investment channel via lower cost of capital, higher profitability of projects, and impact on AD and future LRAS.
- Exchange rate channel: rate cuts can depreciate the currency, improving net exports and shifting AD right, but effects depend on elasticities and openness.
- Asset price channel and portfolio balance: lower yields raise equity and house prices, boosting wealth and collateral and supporting consumption and investment; QE amplifies this at low rates.
- Expectations channel: policy can influence confidence, which can magnify or mute mechanical effects; credibility of the central bank matters.
- Evaluation of QE at low rates: can lower long-term yields and raise asset prices, but effectiveness depends on banks lending, investors rebalancing and households spending; may have diminishing returns and distributional consequences.
- Limits due to liquidity trap: when rates near zero, conventional cuts are ineffective; QE may help but is uncertain.
- Time lags: recognition, implementation and transmission lags can mean policy is too late or causes inflation later; variable lags complicate calibration.
- Balance-sheet constraints: high household or corporate debt and weak collateral reduce the pass-through to spending.
- Other limits: supply-side constraints, global factors, and fiscal policy interactions; monetary policy may be less effective when the negative gap is due to structural problems.
- Consideration of when monetary policy is relatively more effective, e.g. when confidence is responsive, banks lend freely, and the economy has spare capacity, versus when it is less effective, e.g. deep liquidity traps or severe balance-sheet recessions.
- Supported judgement weighing the above, for example that monetary policy is an important and often rapid tool to reduce a modest negative output gap but is unlikely to fully close a deep, balance-sheet driven gap on its own and works best in combination with fiscal or supply-side measures.
