Measurement of Inequality
Sources of Inequality
Why is Inequality a problem?
Inequality at work and discrimination
Inequality Data
I. Measurement of Inequality



How do we measure the equality or inequality
of any distribution?
Variance – Measure of dispersion of a
distribution. Formula?
Dealing with income, percentage of income
each 10% (or 20% etc.) of recipients receive
I. Measurement of Inequality

Lorenz Curve

Start with lowest income recipient up to highest on
horizontal axis

Vertical axis is percentage of income received
I. Lorenz Curve
I. Gini Ratio




Gini Ratio
G=A/(A+B)
Gini Ratios of various
nations
What is happening to
world income
equality/inequality
among nations?
II. Sources of Inequality




Different levels of natural ability
Different levels of human capital, i.e. acquired
skills and abilities
Monopoly power
Discrimination
III. Why is Inequality a Problem?




Do we want incomes to be perfectly equal?
Why or why not?
What happens if incomes are too unequal?
How do we define “too” unequal? What
standard do we use?
What is the impact of equality on social
cohesion? Does this matter?
IV. Inequality at Work and Discrimination




What are the sources of gender inequality of
pay at work?
What does it mean if we say women earn
$.78 cents for every dollar a man earns, what
could be the causes of that?
Can any of the causes be something other
than discrimination?
What might be the non-discriminatory
sources of inequality?
IV. Inequality at Work and Discrimination



Why might women choose different jobs from
men?
What occupations did women traditionally
enter and what were the characteristics of
those occupations?
Are any of the non-discriminatory sources of
the gender wage gap likely also to apply to
the racial wage gap?
