In a specific credit market model with one lender and five borrowers, two of whom are excluded and earn zero income, the relationship between the lender's share of total income (s) and the Gini coefficient (g), a measure of income inequality, is given by the formula: g = (4s + 1) / 5. This formula is valid for s ≥ 0.25. If a market change causes the lender's income share (s) to increase from 0.3 to 0.4, what is the resulting impact on income inequality?

Credit Market Model Validation

For a credit market model with one lender and five borrowers where two are excluded (earning zero income), the formula g = (4s + 1) / 5 accurately calculates the Gini coefficient (g) based on the lender's income share (s), regardless of the value of s.

In a specific credit market model with one lender and five borrowers (two of whom are excluded and earn zero income), the Gini coefficient (g), a measure of inequality, is a linear function of the lender's income share (s). The formula is given by: $g = \frac{4s + 1}{5}$ This relationship implies that for every 0.10 increase in the lender's income share, the Gini coefficient will increase by exactly ______.

Interpreting an Inequality Model

In a specific economic model of a credit market, the relationship between income inequality (g) and the lender's share of total income (s) is given by the formula: g = (4s + 1) / 5. This model involves one lender and five borrowers, two of whom are excluded and earn no income. The formula is valid only when the lender's income share is at least 1/4. Match each component of this model with its correct description or implication.
