Maruva has experienced economic growth, but many children in remote districts lack reliable transport to school. The government defines relative poverty as household income below 60% of median household income.
Low-income households often withdraw teenagers from school so that they can work. Limited education reduces their human capital, productivity and future earnings. A pilot programme provides school meals and transport to children in low-income districts.
Maruva finances a means-tested child benefit partly through a progressive tax on personal income. Critics claim that higher marginal tax rates may weaken incentives to work and encourage tax avoidance.
Supporters argue that the benefit raises disposable income immediately, while school provision addresses inequality of opportunity. However, complicated applications may prevent eligible households from receiving support.
Households below the relative-poverty line before and after the programme.

Export-oriented factories have expanded in coastal Rovina, while unemployment remains high in former mining towns. Differences in skills and employment opportunities have increased income inequality.
Many employed adults still live below the national minimum income standard. The government proposes a higher minimum wage and vocational training for displaced mining workers.
The minimum wage would rise from 9 to 11 rivas per hour. Employers argue that the increase may reduce employment in labour-intensive firms, while trade unions expect higher incomes and lower worker turnover.
Informal workers are not legally covered. The government is therefore considering an in-work transfer for low-income households alongside stronger enforcement of labour law.
Covered labour market in Rovina at the initial and proposed minimum wages.
| Hourly wage / rivas | Labour supplied / workers | Labour demanded / workers |

Selucia's national poverty rate is based on household income. Surveys nevertheless show that some households above the income threshold lack sanitation, reliable electricity and access to clinics.
The government is introducing the Multidimensional Poverty Index (MPI) to supplement its income measure. Officials expect it to reveal overlapping deprivation in health, education and living standards.
Rural clinics charge fees that discourage low-income households from seeking preventive treatment. The government has introduced targeted healthcare subsidies financed by an excise tax on luxury cars.
Better health may increase human capital and labour productivity. However, remote households are often omitted from official surveys, making it difficult to target spending accurately.

Asteria relies heavily on a broad sales tax. Since low-income households spend a larger proportion of their income, economists describe this tax as regressive relative to income.
The government proposes removing the sales tax from basic food and increasing personal income tax on high earners. Revenue would finance housing allowances and public childcare.
Supporters expect the reforms to increase disposable income at the bottom of the distribution and shift the Lorenz curve towards equality. Opponents predict avoidance, lower labour-force participation and reduced entrepreneurship.
The childcare programme is intended to reduce gender inequality in employment. A transfer payment would also be paid to low-income tenants facing high urban rents.
Annual income and sales tax paid by representative households in Asteria.
| Household | Annual income / asters | Sales tax paid / asters |
|---|---|---|
| Low-income | 20 000 | 1 600 |

Severe flooding destroyed homes and fishing equipment in Pelago. Many households lost both current income and productive assets, demonstrating the difference between income and wealth.
The government reports poverty using an international poverty line adjusted for purchasing power. Local charities argue that a national minimum income standard better reflects Pelago's unusually high transport and housing costs.
Emergency cash transfers raised consumption, while grants helped fishing families replace boats and equipment. The government is also building flood-resistant housing in the poorest districts.
Critics argue that universal reconstruction grants waste resources on wealthy households. Supporters respond that means testing would delay payments and exclude families whose records were destroyed.
Poverty survey results in Pelago after the flood.
| Poverty threshold | People below threshold / number | People surveyed / number |

Women in Darsana have similar average qualifications to men but are under-represented in senior occupations. Researchers attribute part of the wage gap to discrimination in recruitment and promotion.
The government has introduced transparent pay reporting, equal-pay enforcement and subsidised childcare. It argues that these policies promote equality of opportunity rather than guaranteeing equal outcomes.
Businesses warn that compliance costs may discourage hiring. Supporters argue that using workers according to productivity rather than gender improves resource allocation and raises national output.
Persistent exclusion can increase poverty among single-parent households and weaken social stability by reducing trust in institutions.

Automation has raised productivity in Vardos's logistics sector but reduced demand for routine warehouse labour. Demand has increased for technicians with advanced digital skills, widening differences in human capital and earnings.
Displaced workers may experience structural unemployment because their skills do not match available vacancies. The government offers retraining grants and temporary unemployment benefits.
Shareholders have received higher profits as firms adopt automation. Since financial assets are concentrated among richer households, technological change may increase wealth inequality as well as income inequality.
Employers argue that automation reduces prices and creates new occupations. Trade unions seek stronger transfers and a tax on unusually large capital gains to finance lifelong learning.
Employment and training outcomes for displaced warehouse workers in Vardos.

House prices in Elmont have risen much faster than wages. Older homeowners have gained substantial net wealth, while young tenants spend a growing share of income on rent.
A household may have low current income but own valuable housing because income is a flow whereas wealth is a stock. The government is considering a recurrent property tax with rebates for low-income homeowners.
Revenue from the property tax would finance social housing and deposits for first-time buyers. Economists argue that wider asset ownership may reduce insecurity and intergenerational inequality.
Opponents claim that the tax would be unfair to asset-rich but cash-poor retirees. Supporters propose allowing deferred payment until a property is sold. The objective is greater equity, not identical asset ownership.
Annual disposable income and housing costs for two households in Elmont.
| Household | Annual disposable income / elms | Annual housing costs / elms |

Commercial banks in Navira require land as collateral. Since land ownership is concentrated, many tenant farmers cannot borrow to purchase irrigation equipment or improved seeds. This is an example of inequality of opportunity.
Low productivity and unstable income contribute to absolute poverty in rural districts. The government has established a publicly guaranteed microcredit programme for low-income farmers.
Access to credit may raise investment, productivity and income. However, crop failures can leave borrowers with debts exceeding the value of their assets.
The government is combining credit with agricultural training and weather insurance. Critics question whether subsidised loans are preferable to targeted government spending on irrigation and rural schools.

Oranta's household survey excludes many homeless people, undocumented migrants and residents of remote settlements. Informal earnings and income received in kind are also under-reported.
The government uses an international poverty line converted using purchasing power parity. City authorities argue that the national result understates urban deprivation because rents are much higher in the capital.
Oranta plans to combine income data with indicators of schooling, nutrition, sanitation and housing. A person whose weighted deprivation score reaches the cut-off will be classified as poor using a composite indicator.
Improved measurement will be costly, and choices about indicators, weights and thresholds remain normative. Nevertheless, policy makers expect better data to improve the targeting of food and housing assistance.

Migrant workers contribute to Calidia's agriculture and construction sectors but often lack recognised qualifications. Some employers pay migrants less than citizens doing similar work.
The government proposes recognition of overseas qualifications, language training and stronger equal-pay enforcement. These measures aim to reduce inequality of opportunity and occupational segregation.
Most migrants pay consumption taxes, but undocumented workers cannot claim unemployment benefits. Since low-income households spend a large share of income, indirect taxation may increase their total tax burden.
The government is considering a temporary means-tested transfer for low-income households regardless of citizenship status. Critics fear that the policy will be costly and politically unpopular.
Average monthly earnings for comparable work in Calidia.

House prices and financial-asset values have increased rapidly in Country D. Table 1 compares the distribution of annual income with the distribution of net wealth. Net wealth is measured as assets minus liabilities. For each measure, households are ranked separately from lowest to highest according to that measure and divided into five equally sized quintiles. Thus, the annual-income shares and net-wealth shares in Table 1 refer to their respective rankings.
Quintile shares; households are ranked separately from lowest to highest for annual income and net wealth.

Using the text/data provided and your knowledge of economics, recommend a policy that the government of Country D could use to reduce wealth inequality.
Automation and international competition have reduced demand for routine labour in Country F. Workers from low-income households have limited access to vocational training, and women remain under-represented in higher-paid occupations.
Table 1 shows household income shares before and after a pilot programme combining vocational education, childcare and enforcement of equal-pay legislation.
Household income shares by quintile before and after the pilot programme.
| Household quintile | Before programme / % | After programme / % |
|---|---|---|
| Lowest 20% | 4 | 6 |
| Second 20% | 8 | 10 |
| Third 20% | 13 | 15 |
| Fourth 20% | 25 | 25 |
| Highest 20% | 50 | 44 |
The government trained 50 000 unemployed people at an annual cost of 2400 solars per participant. The employment rate among participants increased from 52% to 68%. Each additional employed participant earns an average of 18 000 solars per year and pays 10% of this income in personal income tax.
Table 2 provides additional labour-market and poverty data.
Labour-market and poverty indicators in Country F
| Indicator | Before programme | After programme |
|---|---|---|
| Average hourly earnings: men | 24 solars | 24 solars |
| Average hourly earnings: women | 19.20 solars | 19.20 solars |
| Target population | 600 000 people | 600 000 people |
| People below poverty line | 120 000 people | 84 000 people |

Using Table 2, calculate the gender hourly earnings gap as a percentage of men's hourly earnings.
Calculate the programme's gross annual cost, the number of additional employed participants, the additional income-tax revenue and the fiscal cost after this additional tax revenue.
Using Table 2, calculate the change in the target population's poverty rate in percentage points and as a percentage of the initial poverty rate.
Explain how globalisation and technological change can increase income inequality in Country F.
Using the text/data provided and your knowledge of economics, recommend a policy or complementary policy package to reduce inequality of opportunity in Country F.

Using an AD/AS diagram, explain how a high level of income inequality may limit economic growth.
Using real-world examples, discuss the view that reducing income inequality will always increase economic growth.
Using a Lorenz curve diagram, explain how changes in direct and indirect taxation may alter a household's total average tax rate and the distribution of disposable income. Distinguish between standard disposable income after direct taxes and transfers and the effect of indirect taxes on post-tax purchasing power; assume transfer payments and benefits in kind are unchanged.
Using real-world examples, evaluate whether the progressivity of a country's tax system should be judged by taxation alone.
Using labour market diagrams, explain how technological change may increase income inequality.
Using real-world examples, discuss the effectiveness of government policies in preventing technological change from increasing poverty and inequality.
Using an AD/AS diagram, explain how a universal basic income may affect poverty, aggregate demand and potential output.
Using real-world examples, evaluate whether a universal basic income is more effective than targeted transfer payments in reducing poverty and inequality.

Torvia's contributory pension system provides high benefits to workers with continuous formal employment. People who spent years in unpaid care or informal work often receive very low pensions.
Many low-income retirees own no financial assets and are vulnerable to rent and food-price increases. The government proposes a universal basic pension, which is a form of universal basic income restricted to people above retirement age.
The pension would be financed through progressive personal income taxation and reduced tax concessions on private pensions. Supporters expect lower absolute poverty and greater security.
Critics argue that wealthy retirees do not need the payment and that population ageing will raise its fiscal cost. A means-tested pension would be cheaper, but complex applications may cause non-take-up and stigma.
Pension poverty among retirees in Torvia before and after a universal pension.
| Measure | Before pension / people | After pension / people |
|---|---|---|
| Total retirees | 800 000 | 800 000 |
| Retirees below absolute-poverty line | 176 000 | 96 000 |
Fiscal information for the proposed universal basic pension, including the stated offset from recovered tax concessions.
| Item | Value |
|---|---|
| Eligible retirees | 800 000 people |
| Pension payment | 500 torins per month |
| Payments per year | 12 |
| Recovered tax concessions | 1.2 billion torins per year |
| Progressive income-tax revenue | Not quantified separately |
Define the term universal basic income (Text A, paragraph 2).
Define the term absolute poverty (Text B, paragraph 1).
Using Table 1, calculate the absolute-poverty rate before and after the pension and the percentage decrease in the number of retirees in poverty.
Using Table 2, calculate the gross annual cost and the net annual cost after recovered tax concessions.
Using a poverty cycle diagram, explain how the universal pension may reduce persistent poverty among retirees (Text A).
Using a Lorenz curve diagram, explain how financing the pension through progressive taxation may affect disposable-income inequality (Text B).
Using an AD/AS diagram, explain the likely short-run effect of the universal pension on Torvia's aggregate demand (Text A).
Using a labour market diagram, explain one possible effect of higher personal income taxation on labour supply (Text B).
Using information from the texts/data and your knowledge of economics, discuss whether a universal basic pension is preferable to a means-tested pension for reducing poverty and inequality in Torvia.
Country E is considering a universal basic income (UBI) of 600 florins per month for each of its 8 million adults. Existing means-tested benefits costing 18 billion florins per year would be abolished, and the government expects to save 1.2 billion florins in annual administration costs.
Median annual disposable income is 30 000 florins. Country E defines relative poverty as income below 60% of median disposable income. Table 1 shows the distribution of adults around the relative-poverty threshold before the UBI. Assume that the UBI raises every adult's annual income by 7200 florins and that the median and poverty threshold remain unchanged.
Distribution of adults by annual disposable income before the UBI.
| Annual disposable income / florins | Adults / million |
|---|---|
| Below 10 800 | 0.6 |
| 10 800 to below 18 000 | 1.1 |
| At least 18 000 | 6.3 |
| Total | 8.0 |
To help finance the UBI, the government proposes the additional personal income levy shown in Table 2.
Proposed marginal additional personal income levy; the UBI is excluded from the levy base. Band populations are not provided, so total levy revenue cannot be calculated.
| Annual income band (UBI excluded) / florins | Marginal additional levy rate |
|---|---|
| 0–30 000 | 0% |
| 30 001–70 000 | 10% |
| Above 70 000 | 20% |
An adult earning 90 000 florins also spends 24 000 florins, including a 20% indirect tax, on taxable goods and services.
Define the term universal basic income.
Calculate the gross annual cost and the net additional annual fiscal cost of the proposed UBI.
Using Table 1, calculate the relative-poverty threshold and the relative-poverty rates before and after introduction of the UBI.
Explain why a UBI may reduce absolute poverty while having a smaller long-run effect on relative poverty than the calculation suggests.
Using Table 2, calculate the additional personal income levy paid by an adult earning 90 000 florins, its average rate and its marginal rate.
Calculate the indirect tax included in the adult's expenditure.
Explain one possible effect of the UBI on incentives to work.
Using the text/data provided and your knowledge of economics, recommend whether the government of Country E should introduce the proposed universal basic income.
