Answer all questions in full sentences where required. The final 25-mark question requires a developed evaluative response. Total time guidance 60 minutes.

Define what is meant by a market-based supply-side policy in the UK context, distinguishing it from an interventionist supply-side approach.

(Total for Question 1 is 2 marks)

Data extract: UK multifactor productivity (MFP) index (2010 = 100) for a simplified recent five-year period: 2016: 102.0, 2017: 103.5, 2018: 103.0, 2019: 104.2, 2020: 103.8. The government enacted a package of market-based reforms focused on deregulation and corporation tax reduction in 2017. Explain how the data show a short-term change in productivity growth after the 2017 reforms, using the figures above.

(Total for Question 2 is 9 marks)

Using the same MFP index from Question 2, calculate the percentage change in MFP between 2016 and 2019. Show your working and give your answer to 2 decimal places.

(Total for Question 3 is 4 marks)

Explain how a reduction in corporation tax is argued to increase business investment and thereby raise LRAS in the UK.

(Total for Question 4 is 3 marks)

Explain how measures to reduce trade union power or increase labour market flexibility are intended to affect wages, employment and LRAS in the UK.

(Total for Question 5 is 3 marks)

Explain how privatisation of a state-owned industry might increase efficiency and thereby raise LRAS in the UK market-based approach.

(Total for Question 6 is 3 marks)

Evaluate the view that cutting corporation tax is the most effective market-based measure to improve UK productivity. In your answer consider mechanism, timescales, distributional effects, possible unintended consequences and alternative market-based measures. Use diagrams where helpful and reach a supported judgement.

Question 1

B1 market-based policy is defined as measures that rely on market incentives and reduced government intervention to improve supply-side performance
B1 contrast such as less regulation, lower taxes, privatisation, or weaker trade union influence, not direct government provision or state investment
Answer: A market-based supply-side policy uses market incentives and reduced state intervention, for example lower taxes, deregulation and privatisation, rather than direct state provision.

Question 2

Level 1 (1-3): Basic statements about the data with minimal linkage to market-based reforms. May describe one or two index values without analysis.
Level 2 (4-6): Clear explanation of how productivity changed after 2017, with some use of the index figures and a plausible link to the timing of reforms, but limited analysis of magnitude or alternative causes.
Level 3 (7-9): Detailed analysis using the data, quantifying changes in growth rates, explaining how the 2017 reforms could plausibly have affected MFP, and considering short-term variability and other possible influences.
Indicative content:
- 2016 to 2017 MFP rises from 102.0 to 103.5, an increase of 1.47%, coinciding with the 2017 reforms.
- 2017 to 2018 MFP falls slightly from 103.5 to 103.0, a fall of 0.48%, suggesting the initial boost was not sustained immediately.
- 2018 to 2019 MFP then rises to 104.2, an increase of 1.17%, possibly reflecting delayed effects of reforms on investment and efficiency.
- 2019 to 2020 small fall to 103.8, showing volatility and that other factors (global conditions, demand shocks) can influence productivity.
- A reasoned argument that reforms may have an immediate signalling effect increasing confidence and investment (explaining the 2017 rise), but capital accumulation and managerial improvements often take time, producing mixed short-term data.
- Consideration that correlation in timing does not prove causation, and other factors such as global trade conditions or measurement noise could explain year-to-year changes.

Question 3

M1 method: (104.2 - 102.0) / 102.0 x 100
A1 = 2.16%, to 2 d.p.
B1 clear working shown
B1 final answer given as 2.16%
Answer: Percentage change = (104.2-102.0)/102.0 x 100 = 2.16%.

Question 4

M1 lower corporation tax increases retained profits and the after-tax return to investment
A1 firms are more likely to undertake capital investment, increasing the stock of capital
A1 higher capital per worker raises productivity and potential output, shifting LRAS to the right
Answer: Reduced corporation tax increases firms' retained earnings and after-tax returns, encouraging capital investment which raises capital stock and productivity, shifting LRAS right.

Question 5

M1 reducing union power can reduce wage rigidity and allow wages to adjust to market conditions
A1 this can lower unemployment or reduce structural mismatches by encouraging firms to hire and adjust hours, increasing employment and effective labour supply
A1 a more flexible labour market raises productive capacity and shifts LRAS to the right
Answer: Weaker union power can reduce wage rigidity, allowing wages and employment to adjust; greater hiring and labour reallocation raises effective labour supply and shifts LRAS right.

Question 6

M1 privatisation exposes formerly state-owned firms to competitive pressure and profit incentives
A1 this encourages cost reduction, better management and investment, and reduces X-inefficiency
A1 greater efficiency and productive investment raise capacity and shift LRAS to the right
Answer: Privatisation increases competitive and profit incentives, reducing X-inefficiency and encouraging investment, which raises efficiency and shifts LRAS right.

Question 7

Level 1 (1-5): Basic statements about corporation tax cuts and a small number of simplistic links to productivity. Little or no development or evaluation, and limited use of economic reasoning.
Level 2 (6-10): Developed explanation of how corporation tax cuts could raise investment and productivity, with some consideration of timescale and one or two limitations or alternative measures, but analysis is uneven and judgement is limited.
Level 3 (11-15): Clear analysis of mechanisms and timescales, with balanced discussion of strengths and weaknesses, including potential unintended consequences and reference to alternative market-based measures. A partial judgement is offered with some evidence.
Level 4 (16-20): Comprehensive analysis covering channels from tax cuts to investment, productivity and LRAS, detailed evaluation of empirical and theoretical limitations, distributional effects and countervailing factors, and comparison with other measures such as deregulation and benefit reform. Well developed judgement.
Level 5 (21-25): Thorough, well-structured evaluation with sophisticated analysis of mechanisms, magnitude and timing, critical assessment of evidence and likely real-world outcomes, clear comparison with alternative market-based policies, and a well-supported, balanced conclusion about the relative effectiveness of corporation tax cuts.
Indicative content:
- Mechanism: lower corporation tax raises after-tax returns and retained earnings, encouraging capital investment, R&D and adoption of productivity-enhancing technologies, shifting LRAS right.
- Timescale: investment and productivity gains from capital accumulation and organisational change take time, so short-run effects may be limited; initial incentive effects may be faster for FDI.
- Magnitude: the size of the tax cut matters; small cuts may have negligible effect if other constraints exist, such as demand weakness or skills shortages.
- Deadweight and distribution: corporation tax cuts primarily benefit shareholders and capital owners; limited direct benefit to workers unless investment leads to higher wages or employment.
- Crowding out and fiscal offset: tax cuts reduce government revenue unless offset, potentially reducing public investment in infrastructure or education that also raises productivity; financing by borrowing may raise interest rates, crowding out private investment.
- Firm heterogeneity: many firms are not investment-constrained; for smaller or credit-constrained firms tax cuts that increase cash flow may more directly boost investment than for large firms with ample retained earnings.
- Alternative market-based measures: deregulation can boost competition and efficiency quickly; reducing benefit generosity can increase labour supply; privatisation may reduce X-inefficiency; sometimes combinations work best.
- Measurement and uncertainty: productivity responds to many factors; correlation between tax changes and productivity growth is not proof of causation.
- Comparative judgement: corporation tax cuts can be effective when targeted and accompanied by measures to improve skills and competition, but alone they are unlikely to be the most effective single measure across the whole economy.
- Conclusion: a balanced view that corporation tax cuts have a role, especially to attract investment, but their effectiveness depends on context and they are unlikely to outperform a package including deregulation, targeted incentives for R&D and labour market reforms in improving UK productivity sustainably.
