Poverty — common mistakes

In exams, you can illustrate the impact of redistribution by drawing two Lorenz curves on one diagram. Show the initial 'pre-tax' curve and then a second 'post-tax and benefits' curve that is closer to the 45-degree line of perfect equality. Label your axes and curves clearly to show you understand the effect of government policy.

No, this is a common misconception confusing equity with equality. Equity refers to fairness, not sameness. Vertical equity, a key principle, suggests it is fair for higher earners to pay a higher percentage in tax to fund services and support for the less well-off. The goal is to reduce excessive inequality to a level society considers fair, not to achieve perfect income equality.

Not all taxes are equally effective for redistribution. Progressive taxes, where the tax rate increases with income, are the primary tool. In contrast, regressive taxes, such as VAT on many goods, can worsen relative inequality as they take a larger percentage of income from the poor than from the rich. Proportional (flat) taxes have a neutral effect on the percentage distribution of income.

Not necessarily, as there is a potential trade-off. While redistribution can reduce poverty, increase social cohesion, and improve opportunities for the poor, it can also create a conflict with economic efficiency. High taxes may discourage work and investment, and generous benefits might reduce the incentive to find a job. The overall impact depends on the specific design of the policies and finding a balance between equity and efficiency.
