Re-distribution of income and wealth explained
Re-distribution of income and wealth covers 3 specification points, including a) The distinction between income and wealth and b) Incentives and the poverty trap.

a) The distinction between income and wealth
Income is a flow concept, representing the money received by an individual or household over a specific period. Examples include monthly salaries, weekly wages, interest on savings, and annual dividends. In contrast, wealth is a stock concept, measuring the total net value of assets owned at a specific point in time, such as property, shares, and savings, minus any liabilities like mortgages. The distinction is vital: a high-earning professional might have high income but low wealth due to significant debt, whereas a retiree might have low income but substantial wealth from owning a home outright. Understanding this distinction is essential for evaluating economic inequality and the differing impacts of re-distribution policies.
b) Incentives and the poverty trap
The poverty trap occurs when individuals on low incomes face a disincentive to work longer hours or seek higher-paying jobs. This happens because the combination of income tax and the withdrawal of means-tested benefits results in little or no increase in disposable income, creating a high marginal effective tax rate. For example, if a worker earns an extra £100 but loses £65 in benefits and pays £20 in tax, their net gain is only £15, severely reducing the incentive to earn more. This situation perpetuates relative poverty and limits labour market participation. Governments attempt to mitigate the poverty trap by adjusting benefit withdrawal taper rates, increasing the personal tax allowance, or reforming welfare systems.
c) Taxation and the provision of services
Governments use taxation and the provision of services to redistribute income and wealth, reducing inequality. Progressive taxation, such as income tax where higher earners pay a larger percentage of their income, directly reduces the post-tax income gap. The revenue generated funds essential services like state education, healthcare, and subsidised social housing. By providing services like healthcare free at the point of use, or housing at below-market rents, the government effectively increases the real income of lower-income households who would otherwise struggle to afford them. For example, funding the NHS ensures that healthcare access is not determined by wealth, narrowing the gap in living standards.

Re-distribution of income and wealth exam tips
Marking Points
- Define income as a flow of money received over a specific period of time.
- Define wealth as a stock of assets held at a specific point in time, net of liabilities.
- Distinguish between the two concepts using concrete examples, such as wages (income) and property (wealth).
- Explain the relationship between the two, noting that wealth can generate income (e.g. dividends from shares).
- Define the poverty trap as a situation where an increase in gross income leads to little or no increase in disposable income.
- Explain that the poverty trap is caused by the simultaneous deduction of income tax and the withdrawal of means-tested benefits.
- Calculate or identify the marginal effective tax rate to demonstrate the disincentive to work longer hours.
- Evaluate government policies designed to reduce the poverty trap, such as altering the taper rate of universal credit or other benefits.
- Identify progressive taxation as a mechanism that takes a larger proportion of income from high earners to reduce income inequality.
- Explain how government revenue is used to fund public and merit goods, such as healthcare and education.
- Evaluate the impact of providing state services on the real income and living standards of low-income households.
- Analyse the potential disincentive effects of high marginal tax rates on labour supply and enterprise.
Examiner Tips
- 💡Use the terms 'stock' and 'flow' explicitly when distinguishing between wealth and income to demonstrate precise economic understanding.
- 💡When evaluating inequality, explicitly distinguish between income inequality and wealth inequality, as they require different policy responses.
- 💡Remember that policies designed to redistribute income, such as progressive income taxation, may not effectively redistribute accumulated wealth.
- 💡Use a numerical example to illustrate the poverty trap, showing the net effect of earning additional gross income on disposable income.
- 💡Clearly distinguish between means-tested benefits, which contribute to the poverty trap, and universal benefits, which do not.
- 💡Discuss the trade-off between providing an adequate safety net and maintaining incentives to work when evaluating welfare policies.
- 💡Always distinguish between income inequality and wealth inequality when evaluating government policies.
- 💡Use specific examples of progressive taxes and state-provided services to support your analysis of redistribution.
- 💡Consider the macroeconomic trade-offs, such as the potential negative impact of high taxation on economic growth.
Common Mistakes
- Using the terms income and wealth interchangeably; correction: always specify income as a flow over time and wealth as a stock at a given moment.
- Assuming that high income guarantees high wealth; correction: high income earners may have high consumption and significant debt, resulting in low net wealth.
- Categorising rent received as wealth; correction: rent is a flow of income generated from the stock of wealth held in property.
- Confusing the poverty trap with the unemployment trap; correction: the poverty trap affects those already in low-paid work seeking to increase hours, whereas the unemployment trap affects those out of work deciding whether to accept a job.
- Stating that individuals in the poverty trap lose all their income; correction: they lose a significant proportion of their additional income, not their total income.
- Assuming that increasing the minimum wage automatically solves the poverty trap; correction: higher wages may still be offset by benefit withdrawals and taxation unless the tax and benefit system is reformed.
- Confusing income and wealth; correction: income is a flow of money over time, whereas wealth is a stock of assets at a given point in time.
- Assuming all taxes are progressive; correction: indirect taxes like VAT are regressive and can widen income inequality.
- Stating that providing services redistributes wealth directly; correction: it primarily redistributes real income and living standards, though it can affect wealth accumulation over generations.
