--TASK--
"If we revisit the circular flow of income model below you should realise that in a MARKET SYSTEM, the amount of INCOME THAT A HOUSEHOLD EARNS DEPENDS ON THE QUANTITY & QUALITY OF THE FACTORS OF PRODUCTION THEY OWN, so can you think why this will lead to unequal incomes and ultimately lower abilities to consume goods snd services?"
--WEALTH--
WEALTH refers to a 'STOCK' OF VALUABLE POSSESSIONS such as CASH IN YOUR SAFE, SHARES, BONDS, PROPERTY, GOLD JEWELRY etc...
--INCOME--
INCOME, on the other hand refers to a 'FLOW' OF MONEY YOU RECEIVE OVER TIME, such as WAGES for employment, RENT for properties you own, or INTEREST on loans you have given.
--THINK AHEAD--
"We have all seen headlines like the ones below but how is it possible to come up with these bold statements?", "What methods/metrics can we use to find out the distribution of income by % of the population?"
--THINK AHEAD--
"Look at the data below, what do you think it is showing you?", "What does 'decile' mean?", "What does the 1.1 mean in the 1996 column?", "What does the 34.6 mean in the 1971 column?"
--INCOME QUINTILES--
"The richest 20% of households, earn x% amount of the total income earned, whereas the poorest 20% of households only earn y% of total income"
INCOME INEQUALITY can be measured using INCOME QUINTILES, which are constructed by RANKING HOUSEHOLDS from the POOREST to the RICHEST in terms of % SHARE of TOTAL INCOME, then SPLITTING them into FIVE PARTS (AKA 'QUINTILES').
The FIRST QUINTILE = Total income share (as a %) of the POOREST 20% of households,
The SECOND QUINTILE = Total income share (as a %) of the NEXT POOREST 20% of households
...and so on until the FIFTH QUINTILE represents the total income share of the richest 20% of households.
USAGE: Given that equal income distribution would mean each quintile's income share would be 20%, then it is easy to observe inequalities by looking at how far away each quintile's income share is from 20%.
For example, if we look at the data from the US census, we can see that in 2020, the poorest 20% of households earned only 3% of total income, whilst the richest 20% earned 52.2% of total income
(https://www.census.gov/data/tables/time-series/demo/income-poverty/historical-income-households.html)
--TASK--
Using the table below, MAKE 5 OBSERVATIONS regarding the PATTERN OF INCOME DISTRIBUTION in the US SINCE 1970 to 2020.
--LORENZ CURVE--
Household income disparities can be more easily visualised by using a LORENZ CURVE (WIKI), which can be DERIVED FROM THE INCOME QUINTILES mentioned above.
By plotting the CUMULATIVE % of HOUSEHOLDS on the HORIZONTAL AXIS, and the CUMULATIVE % SHARE OF INCOME on the VERTICAL AXIS, we can DERIVE 'THE LORENZ CURVE'.
IF EACH HOUSEHOLD EARNS THE SAME INCOME, then they will have an EQUAL % SHARE OF TOTAL INCOME, thus THE LORENZ CURVE will be a STRAIGHT LINE RISING FROM ORIGIN, which we call 'THE LINE OF PERFECT EQUALITY'.
However IF INEQUALITIES EXIST, then the LORENZ CURVE will BOW OUTWARDS FROM THE ORIGIN and THE FURTHER AWAY FROM THE LINE OF PERFECT EQUALITY, the GREATER THE LEVEL OF INEQUALITY, and vice versa.
--TASK--
Go to this LINK and extract the 2010 data for the UK and construct a QUINTILE TABLE, as well as a LORENZ CURVE.
Next add the Lorenz curves for SOUTH AFRICA and NORWAY
Finally RANK them in order of LEAST UNEQUAL TO MOST UNEQUAL.
--GINI-COEFFICIENT--
Whilst being visually appealing, the Lorenz curve diagram can get messy if you want to show multiple countries and years, therefore for the sake of easy compilation and comparison, Lorenz curve data can be turned into a single number format called the GINI-COEFFICIENT, that ranges from 0 to 1.
The GINI-COEFFICIENT is calculated by DIVIDING 'THE AREA BETWEEN THE LINE OF PERFECT EQUALITY AND THE LORENZ CURVE', by 'THE AREA BELOW THE LINE OF PERFECT INCOME EQUALITY'.
THE MORE 'BOWED-OUT' THE LORENZ CURVE = THE LARGER THE NUMERATOR => THE LARGER THE LEVEL OF INEQUALITY = GINI COEFFICIENT CLOSER TO '1'
THE LESS 'BOWED-OUT' THE LORENZ CURVE = THE SMALLER THE NUMERATOR => THE SMALLER THE LEVEL OF INEQUALITY = GINI COEFFICIENT CLOSER TO '0'

In your own words, what is the main idea of each quote? Which definition do you find more compelling or accurate? Why?
--ABSOLUTE--
"Absolute poverty refers to..."
ABSOLUTE POVERTY is a condition where HOUSEHOLD INCOME IS BELOW A NECESSARY LEVEL TO MAINTAIN BASIC LIVING STANDARDS (food, shelter, housing). This condition makes it possible to compare different countries and also over time, and does not change with economic growth.
WORLD VISION AUSTRALIA, STRAITS TIMES, BBC, LIFE IN BUKIT MERAH
--RELATIVE--
"Relative poverty refers to..."
RELATIVE POVERTY is a condition where HOUSEHOLD INCOME IS A CERTAIN PERCENTAGE BELOW MEDIAN INCOME.
For example, the threshold for relative poverty could be set at 50% of median incomes. This rate changes with economic growth.
WORLD VISION AUSTRALIA, STRAITS TIMES, BBC, LIFE IN BUKIT MERAH
--🌏RWE TASK🌏--
After you write down the definitions, go and find the actual relative poverty amount for a household in your country of birth to use as a real world example:
"Relative poverty is defined as.....for example the poverty threshold in the UK is calculated as 60% of the UK's median household 'net equivalised' disposable income. In 2022/23, the median household income in the UK was £621 per week, before housing costs and £545 after housing costs were deducted therfore 60% of these medians is £373 and £327 respectively."

--INT'L POVERTY LINES--
THE INTERNATIONAL POVERTY LINE is a monetary threshold updated from $1.90 to $2.15 in 2022 and has since been raised again to $3-a day in June 2025, according to the World Bank.
This line represents the minimum amount of money needed to meet basic needs, (It is adjusted for purchasing power parities (PPPs), so it can be expressed in 'INTERNATIONAL DOLLARS'.

"In your opinion, what is the minimum amount needed for a household of 4 (2 adults + 2 children) to live decently in this country?", "What do you think is the best way to find the answer?", "Do you think it should cover items such as basic mobile data, bus fare, nappies etc....?"
--MINIMUM INCOME STANDARDS--
The MINIMUM INCOME STANDARDS (MIS) is a research method to identify WHAT INCOMES DIFFERENT TYPES OF HOUSEHOLDS REQUIRE TO REACH 'A SOCIALLY ACCEPTABLE 'LIVING STANDARD'.
MIS is the BASIS FOR THE CALCULATION OF THE UK LIVING WAGE, which is defined as the MINIMUM INCOME NECESSARY FOR A WORKER TO MEET THEIR BASIC NEEDS. This is not the same as a subsistence wage, which refers to a biological minimum.
Needs are defined to include FOOD, HOUSING, and other essential needs such as CLOTHING. The goal of a living wage is to ALLOW A WORKER TO AFFORD A BASIC, BUT DECENT STANDARD OF LIVING through employment without government subsidies.

--DIRECT--
DIRECT TAXES, as the name suggests, are taxes that are PAID DIRECTLY TO THE GOV'T and can not be avoided.
Examples include INCOME TAX, BUSINESS PROFIT TAX, WEALTH TAXES, and SOCIAL INSURANCE.
--INDIRECT--
INDIRECT TAXES, as the name suggests are taxes that are PAID INDIRECTLY TO THE GOV'T via the supplier of a good or service that is sold and paid for by a customer, hence it can also be thought of as a CONSUMPTION TAX or a TAX ON SPENDING.
Examples include GST, EXCISE DUTIES, and, TARIFFS.

--GOV'T PROVISION OF MERIT GOODS--
"MERIT GOODS are goods that are beneficial for consumers, often with POSITIVE CONSUMPTION EXTERNALITIES, that are UNDERPROVIDED BY THE MARKET and UNDER-CONSUMED. From the point of view of income redistribution, the issue here concerns low consumer incomes and poverty."
↓
"If income distribution were left entirely to the market, two of the most important merit goods that would be under-consumed due to low incomes and poverty would be EDUCATION and HEALTHCARE. Education and health care are so important that they are often viewed as FUNDAMENTAL HUMAN RIGHTS. This means that it is not enough for governments just to provide education and health care (to supplement the insufficient quantities provided by the market). Governments must also ensure that these are affordable for very low-income groups."
↓
"This can be accomplished when GOVERNMENTS OFFER EDUCATION AND HEALTHCARE FOR FREE (or nearly free) to consumers and is called ‘SUBSIDISED PROVISION’ of the goods and services, because the government offers them to consumers at a price (often zero) that is far below the cost of producing them. Governments may also provide subsidies to private providers to increase supply. In addition, education and health care can be made more affordable through transfer payments."
↓
↓
↓
----GOV'T PROVISION OF INFRASTRUCTURE--
Other merit goods that may require subsidised or direct provision by the government, and that are especially important in developing countries that concentrate large groups of people on very low incomes, include INFRASTRUCTURE, which includes numerous kinds of PHYSICAL CAPITAL, such as CLEAN WATER SUPPLIES, SANITATION, and SEWERAGE. Subsidisation or direct provision by the government makes these more affordable to poor people.
↓
↓
↓
--MARKET INTERVENTION--
GOVERNMENT INTERVENTION IN MARKETS: Governments often intervene in markets in ways that change the distribution of income. Examples include:
↓
MINIMUM WAGE LEGISLATION: "By setting a legal minimum wage, the government raises the lowest permissible wage above the equilibrium market level, thereby raising the wages of low-income (and usually unskilled) workers."
↓
FOOD PRICE CEILINGS: "By setting maximum prices for certain food products (prices below the market-determined equilibrium price), governments can make food more affordable for low-income groups."
↓
PRICE FLOORS FOR FARMERS: "By setting legal minimum prices for certain agricultural products (often involving government purchases of the resulting surpluses), governments raise their prices above the equilibrium market price in order to support farmers’ incomes."
↓
↓
↓
--UNIVERSAL BASIC INCOME--
UNIVERSAL BASIC INCOME: "Basic income guarantee, basic living stipend, guaranteed annual income, universal income security program or universal demogrant" is a sociopolitical financial transfer concept in which all citizens of a given population regularly receive a legally stipulated and equal financial grant paid by the government without a means test.[2][3] A basic income can be implemented nationally, regionally, or locally. If the level is sufficient to meet a person's basic needs (i.e., at or above the poverty line), it is sometimes called a full basic income; if it is less than that amount, it may be called a partial basic income." vox video

--TAXES & EFFICIENCY--
"We have seen how PROGRESSIVE TAXES work to IMPROVE EQUITY and how REGRESSIVE TAXES will WORSEN EQUITY; therefore, we could conclude that more of the former and less of the latter, right?"
↓
↓
↓
"What do you think will happen to the amount of hours of labour your are willing to supply if the direct tax rate goes too high?"
--DIRECT TAXES & EFFICIENCY--
We have seen that THE MORE PROGRESSIVE the direct tax system the GREATER THE AMOUNT OF EQUITY in the distribution of income, however, PROGRESSIVE INCOME TAXES have a DISINCENTIVE EFFECT which leads to a FALL IN THE SUPPLY OF LABOUR which leads to LOWER SAVINGS.
HIGH CORPORATION TAXES act as a DISINCENTIVE TO INVEST which leads to LESS PRODUCTION of CAPITAL GOODS.
LESS LABOUR & CAPITAL => LOWER rates of GROWTH.
SUPPLY-SIDE POLICIES are thus heavily based on REDUCING INCENTIVES TO STAY UNEMPLOYED.
As a counter, we can highlight the role of PROGRESSIVE TAXES in AUTOMATICALLY STABILISING the economy during deflationary and inflationary gaps, which ultimately reduce the volatility and loss of output, hence improving EFFICIENCY over the business cycle.
In addition, we could argue that GREATER EQUITY and TAX REVENUES via GREATER PROGRESSIVITY of the tax system will ALLOW THE LEAST PRODUCTIVE MEMBERS OF THE WORKING AGE POPULATION (Discouraged workers, the structurally unemployed, the malnourished, sick, and poorly educated) to INCREASE THEIR HUMAN CAPITAL, via better access to healthcare and education, and ultimately INCREASE THE LABOUR FORCE and subsequently INCREASE GDP.
--Sentence starter--
"Two of the government's main economic objectives are the 'equitable distribution of income' as well as 'economic growth', however, these two goals often create a 'trade-off' between equity and efficiency. For example, the more progressive the direct tax, the more equitable incomes become; however, this can lead to a disincentive to work which reduces output and efficiency, furthermore..."
↓
--TASK--
"Use the economic simulator below to identify at at least 5 'trade-offs' that a government must make between achieving efficiency and equity."
↓
--INDIRECT TAXES & EFFICIENCY--
INDIRECT TAXES on DEMERIT GOODS as we know CORRECT MARKET FAILURE and IMPROVE EFFICIENCY, however, they are REGRESSIVE and can WORSEN EQUITY.
Furthermore, INDIRECT TAXES are NOT JUST APPLIED TO DEMERIT GOODS and the RATE IS NOT ALWAYS THE SAME for example a government may choose to exempt NECESSITIES such as bread and milk from tax, while imposing different import duties on a variety of goods, meaning that RELATIVE PRICES CHANGE and thus RESOURCE ALLOCATION & ALLOCATIVE EFFICIENCY is impacted.
--GOV'T EXPENDITURE & EFFICIENCY--
"Despite the obvious OPPORTUNITY COSTS, government expenditure on MERIT GOODS is aimed at IMPROVING ALLOCATIVE INEFFICIENCY by CORRECTING their UNDERALLOCATION."
--TRANSFER PAYMENTS & EFFICIENCY--
"TRANSFER PAYMENTS such as UNEMPLOYMENT BENEFIT, may ACT AS A DISCINCENTIVE TO WORK, and thus CREATE A BURDEN ON SOCIETY with little improvements in EFFICIENCY."
↓
"WITHOUT TRANSFER PAYMENTS unemployed workers may become DISCOURAGED and leave the labour force entirely, or turn to ILLEGAL ACTIVITIES to survive, IMPACTING GROWTH and EFFICIENCY."
↓
"TRANSFER PAYMENTS also ACT AS AUTOMATIC STABILISERS during RECESSIONARY GAPS, LESSENING OUTPUT GAPS, and hence INEFFICIENCY."
--GOV'T INTERVENTION & EFFICIENCY--
Government attempts to intervene in the free market by introducing MINIMUM & MAXIMUM PRICES may IMPROVE EQUITY, but as we have seen from the WELFARE LOSS diagrams, they result in MARKET FAILURE and LESS EFFICIENCY.
