The table below shows the Gini coefficients for income before government intervention (market income) and income after government intervention (disposable income) for four countries. A Gini coefficient of 0 represents perfect equality, and 1 represents perfect inequality.
| Country | Market Income Gini | Disposable Income Gini |
|---|---|---|
| Country A | 0.50 | 0.30 |
| Country B | 0.40 | 0.25 |
| Country C | 0.60 | 0.45 |
| Country D | 0.45 | 0.20 |

Figure 5.28: Global Comparison of Market and Disposable Income Inequality
Analysis of Income Redistribution Policies
Two countries, Country A and Country B, have the same Gini coefficient for market income (income before taxes and transfers). However, after accounting for government taxes and transfers, their Gini coefficients for disposable income differ as shown below:
Country Market Income Gini Disposable Income Gini Country A 0.50 0.32 Country B 0.50 0.45 If a country's Gini coefficient for market income (income before taxes and transfers) is higher than another country's, its Gini coefficient for disposable income (income after taxes and transfers) must also be higher.
Explaining the Gini Coefficient Shift
Evaluating Claims About Economic Fairness
A country with a market income Gini coefficient of 0.5 is considering two new policies, each funded by an identical tax increase on the top 1% of earners.
- Policy X: Use the revenue to build and operate a new public transportation system, free for all citizens.
- Policy Y: Use the revenue to double the value of direct cash payments for existing social assistance programs for low-income families.
Which policy is expected to cause a larger immediate reduction in the Gini coefficient

The factory pays a government-mandated tax for every ton of smoke it releases. This situation is an example of an external effect.
