Theme 4 - Poverty and inequality Flashcards
what is income
flow of money measured over time
what is wealth
stock concept
- money measured at a given point in time
what are assets
anything with market value that can generate income
How Income Relates to Wealth
- Individuals with higher incomes are able to save more after covering their basic expenses.
- These savings can be used to purchase assets such as property, stocks, or bonds, which grow in value over time
- The income generated by these assets can be reinvested to acquire even more assets or enhance the value of existing ones.
- This creates a compounding cycle where wealth continues to grow, independent of the original income.
reasons for differentials in income and wealth
Age
As individuals age, they gain work experience and seniority, leading to higher income levels.
- This allows older individuals to save more, invest in assets, and accumulate wealth over time.
- younger individuals often have lower incomes and limited opportunities to build assets.
Education
- Higher levels of education provide individuals with specialized skills that are in demand, enabling access to higher-paying jobs.
- This leads to greater lifetime earnings, higher savings potential, and the ability to invest in wealth-generating assets like property or stocks.
- As a result, individuals with advanced education build and sustain more wealth than those with lower education levels.
Ownership of Financial Assets
- Individuals who own financial assets, such as stocks or bonds, earn income through dividends and capital gains.
- This generates additional streams of income, enabling further investments and the compounding of wealth.
- Consequently, those with financial assets experience accelerated wealth accumulation, widening the gap with those who lack such ownership.
Ownership of Properties
- Property ownership provides rental income and benefits from property value appreciation over time.
- Wealthier individuals can reinvest rental income into further properties or other investments, compounding their wealth.
- This creates a cycle of increasing wealth for property owners, while non-owners face stagnant wealth and reduced savings due to rent payments.
Wage Differentials
- High-skilled workers in sectors like technology or finance earn significantly more than low-skilled workers.
- This enables high earners to save more, invest in financial assets, and build long-term wealth.
- The impact is that wage disparities translate directly into wealth inequalities, as low-skilled workers struggle to accumulate savings or assets.
what is absolute poverty
incomes below a threshold($2/day), individuals unable to access basic needs,
what is relative poverty
incomes below a given median in society
equity vs equality
equity - fairness in the distribution of income
equality - EQUAL distribution of income
what is horizontal equity
equal treatments of equals, eg those with the same incomes will be taxed the same
what is vertical equity
higher income earners in society have to pay the highest tax rates, progressive/proportionate tax systems
causes of poverty
Unemployment (Cyclical/Structural)
- Unemployment reduces individuals’ ability to earn income, pushing them into poverty.
- Cyclical unemployment arises during economic downturns, while structural unemployment reflects a mismatch between workers’ skills and job market needs.
- The impact is a loss of income, reduced standard of living, and increased reliance on government support, deepening poverty levels.
Poor Education/Skills
- Lack of education or relevant skills limits access to higher-paying jobs.
- This reduces individuals’ earning potential and confines them to low-paying or unstable employment.
- As a result, poverty persists as individuals struggle to save or invest in long-term opportunities.
Poor Health/Healthcare
- Health problems reduce individuals’ ability to work and increase their medical expenses.
- Inadequate access to affordable healthcare worsens health outcomes, reducing productivity and job retention.
- This creates a cycle of poverty, as individuals are unable to escape financial hardship due to ongoing health issues.
Wage Differentials (Relative Poverty)
- Wage disparities mean low-income earners cannot afford the same standard of living as higher earners.
- This creates relative poverty, even in economies with high average incomes.
- The impact is social inequality, reduced social mobility, and long-term disparities in wealth and opportunities.
- Bad Luck (Born into Poverty/Single Parent)
- Individuals born into poor families face fewer opportunities for education, networking, and career advancement.
- Single-parent households often have limited income streams and higher living costs.
- The result is intergenerational poverty, as disadvantaged individuals struggle to break out of their circumstances.
- Tax Cuts for Well-Off (Relative Poverty)
- Tax cuts for high-income earners increase income inequality by concentrating wealth among the already affluent.
- This reduces government revenues for welfare programs and social support systems.
- The impact is a widening income gap, with low-income earners falling further into relative poverty.
Subsistence Agriculture (Developing Countries)
- Dependence on subsistence farming limits income potential, as output is consumed rather than sold.
- Farmers are vulnerable to weather shocks and lack access to modern technology or credit.
- This results in persistent poverty, with little opportunity for economic advancement or savings.
Benefit Levels
- If unemployment benefits, disability payments, or other social welfare programs are inadequate, individuals reliant on these schemes struggle to meet basic needs. This leads to higher levels of absolute poverty,
- Poor benefit levels exacerbate income inequality, reduce social mobility, and place additional strain on charitable organizations and public services like healthcare.
Employment Law Levels
Weak employment laws contribute to poverty by allowing bad working conditions and low wages.
- In countries with minimal regulation, employers may offer insecure contracts, low pay, and limited benefits. For example, workers on zero-hour contracts or in the gig economy may lack job security and income stability, trapping them in working poverty.
- leaves individuals vulnerable to financial shocks, while low pay perpetuates cycles of poverty, particularly in sectors with high labor demand but low bargaining power, such as retail or hospitality.
Trade Unions
Declining trade union membership weakens workers’ ability to negotiate for better wages and conditions, worsening poverty.
- Trade unions historically provided a counterbalance to employer power, ensuring fair pay and decent working conditions. As union influence declines, wage growth stagnates, and the share of income accruing to workers falls, particularly for low-income earners. Without collective bargaining, workers in industries with limited skills or competition are more likely to face exploitation.
- Reduced union influence contributes to income inequality and working poverty, particularly in sectors dominated by low-paid, non-unionized workers. This also increases reliance on government welfare programs to fill the income gap.
explain the lorenz curve
The Lorenz Curve is a graphical representation of income or wealth distribution in an economy. It compares the cumulative share of income (or wealth) received by percentages of the population, starting with the poorest.
The x-axis represents the cumulative percentage of the population (from 0% to 100%).
The y-axis represents the cumulative percentage of income or wealth.
A 45-degree line represents perfect equality (everyone has the same income).
The Lorenz Curve lies below the 45-degree line, showing the actual distribution of income or wealth.
explain the gini coefficient
The Gini Coefficient quantifies inequality based on the Lorenz Curve. It is calculated as the ratio of the area between the Lorenz Curve and the 45-degree line to the total area under the 45-degree line.
Formula:
𝐺 =𝐴/𝐴+𝐵
A = Area between the Lorenz Curve and the line of perfect equality.
B = Area under the Lorenz Curve.
G: Value between 0 and 1, where 0 indicates perfect equality and 1 indicates maximum inequality.
Interpretation:
𝐺=0 : Everyone has the same income (perfect equality).
𝐺=1: One person has all the income (maximum inequality).
Example:
A country like Sweden might have a Gini Coefficient of 0.25, indicating low inequality.
A highly unequal country, such as South Africa, might have a Gini Coefficient of 0.63.
difference between wealth and income
income is a flow whereas wealth is a stocn
what are transfer payments
payments made from the govt to economic agents
what are mean tested benefits
benefits given to people who desperately need it, then taken away when living conditions improve
policies to redistribute wealth and income
🏛️ 1. Progressive taxation
→ Higher-income individuals pay a larger percentage of their income in tax
→ This increases the tax burden on those with greater ability to pay
→ Government uses this revenue to fund public services or benefits
→ Helps reduce the post-tax income gap and promote equity
💰 2. Welfare payments (e.g. Universal Credit, pensions)
→ Direct transfers to low-income or vulnerable groups
→ Increases their disposable income
→ Allows them to access essential goods and services
→ Improves living standards and reduces relative poverty
📚 3. Free or subsidised education and healthcare
→ Removes cost barriers to accessing vital services
→ Increases human capital, especially for lower-income households
→ Improves job prospects and earnings potential
→ Leads to long-term reduction in income inequality
🧾 4. Minimum wage laws
→ Sets a legal wage floor to protect low-paid workers
→ Increases earnings at the bottom of the income distribution
→ Reduces in-work poverty
→ Promotes a more equitable wage structure
🏘️ 5. Subsidised housing or housing benefits
→ Reduces the housing cost burden for low-income households
→ Frees up income for other essentials
→ Improves access to safe living conditions
→ Helps reduce wealth inequality caused by housing asset ownership
policies to redistribute wealth and income(eval points)
- State of government finances
If the government is running a fiscal deficit, heavy redistribution through welfare spending or tax cuts for the poor may be unsustainable.
This could lead to borrowing, increasing national debt.
In the long term, higher interest repayments reduce fiscal flexibility.
Therefore, redistribution must consider public sector budget constraints.
- Effectiveness of targeting
If redistribution policies aren’t well-targeted (e.g., universal benefits instead of means-tested), they may not reach the most disadvantaged.
This reduces their impact on poverty or inequality.
It also increases opportunity cost, as resources could be used more efficiently.
Targeted redistribution (e.g., child tax credits) is more cost-effective.
- Disincentive effects
Higher marginal tax rates to fund redistribution might discourage work and productivity among high earners.
This reduces tax revenue and harms economic growth.
However, these effects depend on the elasticity of labour supply.
If labour is inelastic, work effort won’t fall significantly—so redistribution may still be effective.
- Short-term vs long-term impact
Cash transfers and benefits can reduce poverty in the short term.
But investment in education, healthcare, and skills helps reduce inequality in the long term.
Long-term redistribution improves equity and efficiency.
So a balanced approach of immediate support and long-term investment is ideal.
how is poverty measured
- the human poverty index
- HPI-1 - used to measure deprivation in the most severely affected nations in the world, eg Haiti
- HPI - 2 - More relevant for developed nations
- both use components like life expectancy,employment,literacy levels,and relative income to other countries
or
the ratio method, where poverty is measured by calculating income proportion spent on necessities
some countries gini coefficient
Avg gini = 0.3
UK - 0.35
US - 0.37
South Africa, top 1% own 30% of all income (0.67)
After moving to capitalism, China gini increased from 0.44 to 0.55
Netherlands and Denmark gini has been < 0.28 since 1970s
Causes of wealth and income inequality between countries
🌍 1. Differences in levels of education
Some countries have underdeveloped education systems →
This limits the accumulation of human capital →
Workers are less productive and earn lower wages →
Leading to lower incomes and weaker economic development.
💸 2. Historical exploitation and colonialism
Colonial powers extracted resources and wealth from colonised nations →
Infrastructure was often designed for resource extraction, not long-term development →
Post-independence, many countries lacked industrial capacity and institutions →
This contributed to long-term poverty and inequality with developed nations.
💼 3. Differences in access to capital and investment
Developing countries often lack access to finance and foreign investment →
This restricts business growth and innovation →
Leading to low productivity and limited job creation →
Resulting in lower national income levels over time.
🏗 4. Weak institutions and governance
Poor countries may have weak legal systems and high corruption →
This deters investment and misallocates public funds →
Economic growth is undermined and inequality persists →
While richer countries benefit from strong, stable institutions.
💱 5. Unfavourable terms of trade
Developing countries often rely on exporting low-value primary goods →
While importing high-value manufactured goods →
This creates trade imbalances and stifles income growth →
Perpetuating income inequality relative to industrialised nations.
what is UBI
universal basic income is a welfare policy that guarantees a monthly income to EVERYONE in the population, regardless of their current income, employment, or other factors
features of UBI
- covers basic needs
- unconditional
- funded through taxation
pros of UBI
- Supports Those Out of Work
- UBI ensures that individuals who are unemployed still receive a stable income, providing financial security.
- Reduces poverty rates and prevents individuals from falling into severe financial hardship during periods of unemployment, such as economic recessions or personal crises. - Overcomes Problems with Means-Tested Benefits
- Means-tested benefits can disincentivize work due to the “poverty trap,” where increased income leads to a loss of benefits. UBI eliminates this issue by providing income unconditionally.
- Encourages more individuals to seek employment or increase working hours without fear of losing their financial safety net. - Always an Incentive to Work
- Unlike some welfare systems, UBI is not reduced or withdrawn as individuals earn more, ensuring that there is always a financial reward for working.
- Encourages workforce participation, increasing productivity and potentially leading to economic growth. - Everyone is Eligible (Income Top-Up)
- UBI is universal, meaning all citizens receive it regardless of their income level, acting as an income supplement for low- and middle-income earners.
- Reduces income inequality and provides greater financial security for the entire population, promoting social cohesion. - Supports Socially Beneficial Activity
- UBI allows individuals to engage in unpaid but socially valuable activities, such as caregiving, volunteering, or community service, without financial strain.
- Enhances societal well-being by encouraging activities that may not generate direct economic output but have significant social value. - Can Support Entrepreneurship
- With a guaranteed income, individuals are more likely to take risks, such as starting a business, as UBI provides a financial safety net.
- Encourages innovation and entrepreneurial activity, potentially leading to job creation and economic growth in the long term.
