Estara has experienced moderate economic growth, but manufacturers report shortages of technicians while many former agricultural workers remain unemployed. The government describes this as structural unemployment.
It has introduced vocational courses designed jointly by colleges and employers. The courses are intended to increase human capital, labour productivity and occupational mobility. However, trainees may not enter employment for several years.
The government is constructing a freight railway linking industrial areas to the main port. This infrastructure should reduce delivery times and attract private investment. Construction expenditure will increase aggregate demand immediately, whereas the increase in productive capacity may occur later.
Critics argue that the programme is expensive, may increase government debt and could cause inflation because Estara is currently close to full employment.
Manufacturing output and employment before and after the programme.
| Period | Manufacturing real output / billion estars | Manufacturing employment / million workers |
|---|---|---|
| Before programme | 48 | 1.20 |
| After programme | 60 | 1.25 |

Cordania has a legally binding minimum wage. Small firms argue that it raises labour costs and reduces employment of inexperienced workers. Trade unions argue that it limits poverty and supports worker motivation.
The government proposes reducing the minimum wage for young workers and limiting unions’ role in wage bargaining. It expects greater labour-market flexibility, although opponents fear lower wages and greater income inequality.
Unemployment benefits will also be reduced. The government expects this to increase the incentive to search for work and accept available jobs.
Economists warn that Cordania’s current slowdown is caused mainly by weak aggregate demand. Benefit reductions may therefore reduce consumption without creating enough vacancies.
Overall labour-market quantities at the binding minimum wage in Cordania; the table does not provide a separate figure for young workers.
| Worker group | Minimum wage / cordas per hour | Labour demanded / workers | Labour supplied / workers |
|---|---|---|---|

Belland transferred its state-owned passenger railway to private investors. This privatization was intended to create stronger profit incentives, reduce costs and improve service quality.
Passenger journeys subsequently increased, but fares also rose. Consumer groups argue that the railway remains a natural monopoly and that ownership transfer alone cannot create competition.
The government also introduced deregulation, simplifying rules governing new freight operators. Entry increased and delivery costs fell. However, railway unions claim that reduced safety requirements have increased risks to workers and passengers.
The competition authority is considering fare controls and minimum safety standards. These measures could protect consumers but might weaken incentives to invest.
Passenger railway data before and after privatization.
| Period | Passenger journeys / millions per year | Average fare / bellars per journey |
|---|---|---|
| Before privatization | 40 | 8 |
| After privatization | 50 | 10 |

Darsia reduced its business tax rate to encourage investment. The government expects firms to retain more profit and purchase machinery, but critics claim that firms may instead distribute the additional profit to shareholders.
Personal income taxes were also reduced. This may increase work incentives and entrepreneurship, although some workers may choose more leisure after their disposable income rises.
Darsia offers tax credits for research and development (R&D) because new ideas may create benefits for firms other than the original innovator. Public universities have also received research grants.
The tax cuts and R&D tax credits reduce government revenue, while research grants increase government expenditure. If the resulting budget deficit is financed by borrowing, future debt servicing or cuts to education and infrastructure may offset the supply-side gains.
Annual private investment in Darsia before and after tax reform.
| Period | Private investment / billion dars |
|---|---|
| Before tax reform | 24 |
| After tax reform | 30 |
Representative firm's profit and business-tax rates

Faron reduced tariffs on machinery and consumer products. The government expects trade liberalization to lower input costs and expose domestic firms to stronger competition.
Some inefficient producers have closed, creating structural unemployment. Consumers have benefited from lower prices and greater choice, while exporting firms can purchase cheaper machinery.
Three large firms dominate Faron’s food-processing industry. The government has introduced anti-monopoly regulation, investigating collusion and preventing exclusionary agreements with retailers.
Large firms argue that their scale permits lower average costs and that intervention may reduce investment. Consumer organizations claim that stronger competition will lower prices and encourage innovation.
Prices of an imported machine in Faron, with the trade-model assumption for part (c).
| Price measure / model | Value / farons per machine (where applicable) |
|---|---|
| World price | 20000 |

Galena has introduced an industrial policy supporting battery and medical-equipment production through grants, public procurement and concessional finance. The government expects these sectors to create skilled employment and export capacity.
Critics argue that ministers may select firms for political reasons. Supported firms could become dependent on subsidies and lobby against their withdrawal.
Technical colleges are developing courses with manufacturers, while the government is financing laboratories and reliable electricity networks. This coordination is intended to increase productive capacity and attract private investment.
The programme raises aggregate demand in the short run and requires additional government borrowing. Its long-run success depends on innovation, worker skills and foreign demand.
Annual public support and additional private investment in supported sectors.
| Programme component | Annual amount / billion galens |

Congested roads raise delivery costs and expose residents to air pollution. Harvia is constructing an electric metro and upgrading freight routes. The government expects this infrastructure to improve efficiency and crowd in private investment.
The metro may create positive externalities by reducing congestion and pollution. However, construction is costly, and inaccurate passenger forecasts could leave an underused system.
Harvia defines sustainable economic growth as growth that can continue without undermining future living standards or environmental resources.
The economy is currently operating close to full employment. Construction spending will raise aggregate demand before the transport network substantially increases aggregate supply, potentially increasing inflation and public debt.
Freight journey data before and after the transport upgrade.

Isola has unemployed construction workers while software and renewable-energy firms report vacancies. This structural unemployment reflects a mismatch between workers’ skills and expanding industries’ requirements.
The government funds retraining and relocation grants to improve occupational mobility. Employers help design courses, but completion does not guarantee a job.
Isola is also experiencing a recession caused by falling consumption and investment. Some economists argue that retraining cannot by itself correct cyclical unemployment when firms face insufficient demand.
The government is considering combining retraining with temporary demand-side support. Its budget is limited, and unsuitable courses would waste scarce resources.
Retraining completion, employment outcomes and programme cost in Isola.
| Measure | Value |
|---|---|
| Workers completing retraining (full set of trainees for cost calculation and employment denominator) | 12000 |
| Completers entering employment within six months | 9000 |
| Average programme cost per trainee / isolars | 6000 |
Retraining outcomes in Isola
| Measure | Value |
|---|---|
| Workers completing retraining (full set of trainees; denominator for employment rate and cost) | 12 000 workers |

Jorvik privatized its regional water supplier to improve efficiency and finance replacement of leaking pipes. Privatization created profit incentives, but households cannot easily choose another supplier.
Economists describe the network as a natural monopoly because duplicating reservoirs and pipes would be costly. Following privatization, operating efficiency improved but household charges increased.
The government created an independent regulator that limits charges and sets water-quality standards. The firm argues that strict price controls reduce funds available for infrastructure investment.
Low-income households spend a relatively large share of income on water. Environmental groups also warn that weak regulation could encourage excessive extraction from rivers.
Annual operating cost and water supplied before and after privatization.
| Period | Operating cost / million jors | Water supplied / million |
|---|---|---|
| Before privatization | 480 | 600 |
| After privatization | 450 | 750 |

Kintara has experienced persistent inflation as nominal wages have risen faster than labour productivity. Firms report increasing unit labour costs, weakening export competitiveness.
The government proposes vocational training, automation grants and reduced business taxes. These supply-side policies aim to raise productivity, reduce costs and expand productive capacity.
Training and automation may take years to affect output. Tax reductions and grants may increase consumption and investment immediately, raising aggregate demand.
The central bank warns that if demand expands before productive capacity, inflation may initially accelerate. Critics also question whether tax reductions will generate enough additional investment to justify lost revenue.
Average annual labour cost and output per worker in Kintara.
| Year | Average nominal labour cost per worker / kins | Annual output per worker / units |

Montara’s government reduced the business profit tax and introduced a tax credit for research and development (R&D). It expects the reforms to increase private investment, innovation and productive capacity. Critics argue that some firms may distribute their additional retained profit to shareholders rather than invest it.
Table 1 shows information for Orion Technologies, a representative domestic firm, before and after the reforms.
Orion Technologies before and after Montara’s business tax and R&D reforms.
| Measure | Before reforms | After reforms |
|---|---|---|
| Business profit tax rate / % | 28 | 20 |

Using the text/data provided and your knowledge of economics, recommend whether Montara should rely primarily on cuts in business taxation and R&D tax credits to increase long-term economic growth.
Belland has a legally established minimum wage of 15 crowns per hour. The government argues that reducing the minimum wage to the competitive equilibrium level would increase labour-market flexibility, reduce firms’ costs and improve international competitiveness. Labour unions argue that the reform would increase in-work poverty.
Table 1 presents estimates for Belland’s competitive labour market.
Table 1: Estimated labour-market quantities in Belland
| Hourly wage rate / crowns | Labour demanded / workers | Labour supplied / workers | Annual hours / worker |
|---|---|---|---|
| 15 | 420 000 | 510 000 | 1 600 |
| 12 | 470 000 | 470 000 | 1 600 |
The estimates assume other factors affecting labour demand and supply remain unchanged. Around 40% of minimum-wage workers live in households in the lowest income quintile.
Using Table 1, calculate the excess supply of labour at the minimum wage.
Calculate the percentage change in employment if the wage falls from 15 crowns to the equilibrium wage of 12 crowns.
Using Table 1, calculate the change in the total annual wage bill paid by firms if the wage falls to 12 crowns per hour.

Lumera’s government is considering market-based supply-side policies, including business-tax cuts, deregulation and weaker employment protection. Supporters expect stronger incentives and more flexible resource allocation.
An alternative package of interventionist supply-side policies would expand vocational education, public research and electricity infrastructure. Supporters argue that markets underprovide these activities because they create widespread external benefits.
Market-based reforms may have a smaller direct budget cost, but could increase inequality, job insecurity and environmental damage. Their effects depend on firms and workers responding to incentives.
Interventionist policies can directly target growth constraints but involve taxation, borrowing, government failure and long implementation lags. Lumera is close to full employment, so expenditure may increase inflation before productive capacity expands.
Output per worker in Lumera and comparable economies.
| Economy group | Output per worker / lums |
|---|---|
| Lumera | 42 000 |
| Comparable-economy average | 50 000 |
Annual fiscal figures for the proposed interventionist programme.
| Item | Amount / billion lums |
|---|---|
| Additional proposed interventionist expenditure | 9 |
| Current government expenditure | 81 |
| GDP | 300 |
Define the term market-based supply-side policies (Text A, paragraph 1).
Define the term interventionist supply-side policies (Text A, paragraph 2).
Using Table 1, calculate Lumera’s productivity gap in output per worker and as a percentage of the comparable-economy average.
Using Table 2, calculate proposed interventionist expenditure as a percentage of GDP and the percentage increase in government expenditure.
Using an AD/AS diagram, explain how successful market-based supply-side policies may affect Lumera’s economy (Text A).
Using a positive-externality diagram, explain the case for government funding of vocational education or research (Text A).
Using a minimum-wage diagram, explain how weaker employment protection or wage flexibility might reduce unemployment (Text A).
Using an AD/AS diagram, explain why the interventionist programme may initially increase inflation but reduce inflationary pressure in the long run (Text B).
Using information from the texts/data and your knowledge of economics, evaluate whether Lumera should rely mainly on market-based or interventionist supply-side policies.

Norland’s manufacturers import advanced machinery subject to a tariff. At the same time, firms report substantial production losses caused by preventable worker illness. The government can afford either to eliminate the machinery tariff or to use an equivalent amount of revenue to expand preventative health care, but it cannot initially finance both policies.
Table 1 presents information about imported machinery.
Norland’s current annual advanced-machinery imports
| Measure | Value |
|---|---|
| World price per machine | 50 000 florins |
| Tariff rate | of world-price value |
| Current annual quantity imported | 4 000 machines |
| Tariff basis | Applied to world-price value per machine |
Table 2 presents workforce and health information.
Norland workforce and preventative health programme data.
| Measure | Value |
|---|---|
| Number of workers | 1.2 million |
| Annual output per worker at full attendance | 80 000 florins, assuming 240 scheduled working days are completed |
| Working days per worker annually | 240 scheduled days |
| Current illness-related absence | 6 days per worker annually |
| Forecast absence after programme | 4 days per worker annually |
| Output per working day | Constant; based on 80 000 florins over 240 scheduled days |
Domestic machinery producers employ 8 000 workers and oppose tariff removal. Health clinics are concentrated in cities, although illness-related absence is highest in rural regions.
Define the term trade liberalization.
Using Table 1, calculate the annual tariff revenue that Norland’s government would lose if it eliminated the machinery tariff, assuming the quantity imported remains unchanged.
Calculate the percentage reduction in the domestic price of an imported machine if the tariff is eliminated and the world price is unchanged.
Using Table 2, calculate the forecast increase in Norland’s annual real output if the preventative health programme reduces absence as expected and output per working day remains constant.
Draw an AD/AS diagram showing how successful preventative health care may affect Norland’s macroeconomic equilibrium and productive capacity.
Explain how eliminating the machinery tariff may improve Norland’s international competitiveness.
Using the text/data provided and your knowledge of economics, recommend whether Norland should prioritize eliminating the machinery tariff or expanding preventative health care.
Explain how market-based and interventionist supply-side policies use different mechanisms to improve resource allocation and productive capacity.
Using real-world examples, to what extent can supply-side policies achieve economic growth without reducing equity or environmental sustainability?
