You are expected to explain/analyze (AO2) the relationship between equality and equity, and the meaning of economic inequality (SL/HL)
Equity means economic fairness. In other words, people who work harder jobs that require more skills earn a higher wage, in order to incentivize work. This creates inequalities, as some will earn more than others.
Equality, on the other hand, means everyone earns the same amount, ensuring no inequalities exist.
There are 2 types of economic inequality:
Unequal distribution of income: There are inequalities present in people's income in a society
Unequal distribution of wealth: There are inequalities present in people's wealth in a society
Both can obviously affect the other.
Both income and wealth inequality can be illustrated using the Lorenz Curve and Gini Coefficient.
