Mark scheme · ECO.MAC1 Economic Growth: Causes, Types and the Economic Cycle

Question 1

B1 an increase in real GDP or real national income over a period
B1 it measures a rise in the volume of goods and services produced, not just nominal values
Answer: An increase in real GDP or real national income over time, showing the economy is producing more goods and services.

Question 2

B1 the long-run rate at which an economy can grow without generating rising inflationary pressure, based on growth in productive capacity
B1 determined by changes in factors of production and productivity such as labour, capital and technology
B1 often represented by a vertical LRAS or a trend line of actual output over time
Answer: The long-run rate of growth in an economy's productive capacity, determined by changes in factors of production and productivity, usually shown by a vertical LRAS or a trend line of output.

Question 3

M1 positive output gap occurs when actual GDP exceeds potential GDP
A1 implication: the economy is overheating, causing upward pressure on prices and possible inflation
M1 negative output gap occurs when actual GDP is below potential GDP
A1 implication: spare capacity exists, with higher unemployment and downward pressure on inflation
Answer: A positive output gap is when actual GDP exceeds potential GDP and implies overheating and upward pressure on prices. A negative output gap is when actual GDP is below potential GDP and implies spare capacity, higher unemployment and downward pressure on inflation.

Question 4

B1 identifies one supply-side factor, e.g. increased investment in physical capital such as machinery and infrastructure
A1 explains that more or better capital raises labour productivity and allows greater output for given inputs
B1 identifies a second factor, e.g. improvements in human capital through education and training
A1 explains that better skills increase labour productivity and the effective supply of skilled labour, increasing potential output
Answer: Examples: more investment in physical capital (e.g. new factory equipment, better transport infrastructure) raises productivity and output capacity; improved human capital from education and training raises labour productivity and potential output.

Question 5

M1 technological progress raises productivity of labour and capital, allowing more output from the same inputs
A1 this increases the economy's productive capacity, shifting LRAS to the right
A1 the effect may take time because adoption requires investment, training and replacement of capital goods, causing long time lags before measured output rises
Answer: Technological progress makes labour and capital more productive, increasing productive capacity and shifting LRAS right. The effect may be delayed because firms need time to invest, adopt new technology and train workers, so measured output rises only after these lags.

Question 6

B1 output gap = the difference between actual output (real GDP) and potential output (potential GDP), positive if actual > potential and negative if actual < potential
B1 policymakers might respond to a large negative gap with expansionary fiscal or monetary policy to stimulate AD and reduce unemployment
Answer: The output gap is the difference between actual and potential GDP; if actual is below potential it is negative. Policymakers may use expansionary fiscal or monetary policy to boost demand and reduce unemployment.

Question 7

M1 short-run growth is changes in real GDP due to variations in aggregate demand or utilisation of existing capacity, often temporary
A1 example cause: a rise in AD from lower interest rates or fiscal stimulus can raise real GDP in the short run
M1 long-run/trend growth is a sustained increase in productive capacity, shown as an outward shift in LRAS or trend output
A1 example cause: increases in the quantity or quality of factors of production, such as investment in capital and improvements in education
Answer: Short-run growth is temporary changes in actual GDP from demand or capacity utilisation, e.g. a fiscal stimulus raising AD. Long-run growth is a sustained rise in productive capacity from supply-side improvements, e.g. increased investment and better human capital shifting LRAS right.

Question 8

B1 correctly labelled axes (Price level vertical, Real GDP horizontal)
B1 LRAS shown vertical at potential output and labelled
B1 SRAS upward sloping and AD located to the left of LRAS so actual output is below potential, with both points labelled (Ya and Yp)
B1 negative output gap indicated or shaded as the horizontal difference between Yp and Ya
M1 policy option 1: expansionary monetary policy described, e.g. lower interest rates increase C and I, shifting AD right
M1 policy option 2: expansionary fiscal policy or supply-side policy described, e.g. higher government spending or tax cuts raise AD, or temporary investment in infrastructure raises potential output; explains how it reduces the gap
Answer: Diagram should show AD left of LRAS with Ya < Yp and the horizontal gap marked. Policies: lower interest rates to boost C and I and shift AD right; or fiscal expansion/infrastructure investment to raise AD or raise potential output.

Question 9

B1 boom: high output above trend, low unemployment and rising inflationary pressure
B1 downturn: growth slows, investment and confidence fall, employment growth weakens
B1 recession: significant fall in real GDP, rising unemployment and negative growth for at least two quarters
B1 recovery: GDP growth returns, employment rises and confidence begins to improve
Answer: Boom: output above trend with low unemployment and inflationary pressure. Downturn: slowing growth, falling investment and weakening jobs growth. Recession: falling real GDP and rising unemployment (often two quarters of negative growth). Recovery: GDP growth resumes, employment and confidence start to rise.

Question 10

M1 identifies supply-side cause 1, e.g. increased investment in R&D and capital equipment
A1 explains that this raises productivity and potential output, example: firms adopting automation and new machinery in manufacturing
M1 identifies supply-side cause 2, e.g. improvements in education and training to raise human capital
A1 explains that a more skilled workforce increases labour productivity, example: vocational training programmes raising productivity in services
Answer: Investment in R&D and capital raises productivity and potential output (e.g. automation in factories). Better education and training increase human capital and labour productivity (e.g. vocational training improving service sector efficiency).

Question 11

M1 states mechanism: a fall in AD (C, I, G or net exports) reduces planned spending, causing firms to cut output and employment
A1 explains why this is distinct from supply-side shortfalls: capacity exists but is unused, so output falls without damage to LRAS
M1 gives evidence indicator 1: a rising unemployment rate and falling capacity utilisation indicating spare capacity
A1 gives evidence indicator 2: weak consumer confidence/retail spending and falling business investment pointing to lower AD
Answer: A demand-led recession occurs when AD falls so firms cut output and jobs despite spare capacity. Evidence would include rising unemployment and falling capacity utilisation, plus weak retail spending and falling investment showing weak AD.

Question 12

Level 1 (1-5): Basic statements about supply-side policies with little development, or an answer that lists policies without evaluating their effectiveness. Limited or no attempt to consider alternatives or provide a reasoned conclusion.
Level 2 (6-10): Some analysis of how supply-side policies raise potential output, with developed advantages such as higher productivity and competitiveness. Some consideration of limitations, such as time lags, funding constraints and possible crowding out; limited evaluation of alternatives.
Level 3 (11-15): Clear, sustained analysis and evaluation. Explains mechanisms by which supply-side policies raise LRAS and sustainable growth, weighs strengths (durability, addressing structural barriers) against weaknesses (long time lags, funding costs, distributional impacts), and compares to demand management or mixed approaches. Reaches a balanced, supported judgement that recognises context and trade-offs.
Level 4 (16-20): Comprehensive analysis with well-developed evaluation. Integrates real-world considerations such as the state of spare capacity, the fiscal position, institutional constraints, and political feasibility. Assesses when supply-side policies dominate, when demand-side stimulus is preferable, and the roles of complementary policies. Offers a qualified judgement grounded in analysis.
Level 5 (21-25): Excellent, insightful evaluation. Provides detailed, balanced arguments on both sides, considers magnitude and timing of effects, distributional consequences and measurement challenges, and uses clear reasoning to justify a nuanced conclusion about the relative effectiveness of supply-side policies in restoring sustainable long-run growth after a recession.
Indicative content:
- How supply-side policies increase LRAS: improving human capital (education, training), raising capital stock (infrastructure investment), stimulating innovation (R&D incentives), deregulation improving productivity
- Advantages: raise productive capacity, durable effects on trend growth, improve competitiveness and potential exports, can reduce structural unemployment
- Limitations: long implementation and impact lags, high fiscal cost and opportunity cost, political and practical constraints, possible short-run ineffectiveness if economy lacks demand
- Distributional effects: benefits may be concentrated among skilled workers or capital owners unless policies are targeted, transitional unemployment during reallocation
- Alternatives: demand-side policies such as monetary stimulus or fiscal stimulus can boost short-run recovery when spare capacity exists, but risk inflation if near potential output
- Complementarity: sequencing matters, for example combine short-run demand stimulus with long-term supply reforms to avoid persistent underemployment while raising potential output
- Contextual factors: state of public finances, inflation expectations, global economic conditions, and speed needed for recovery
- Judgement: a supported view that supply-side policies are essential for sustainable long-run growth, but in many recession contexts they should be complemented by temporary demand management, and the case depends on timing, fiscal capacity and the nature of the recession
