On the Lorenz curve, how would you show a gini co-efficient of '1' (I.E perfect inequality)



Is it possible to show? :spzz:



Thank you :)

Re: Lorenz Curve

Gini Coefficient = Area A/Area A+Area B
Since there is no Area B at perfect inequality, hence Area B = 0
Therefore Gini Coefficient = Area A/Area A = 1

Don't know how to qualitatively explain it though.

I know that but I don't think I'm explaining what I'm attempting to ask properly :(

Is that really a question? Just refer to the areas cos it's a stupid question and not even economics.

It's not a question for HSC level economics certainly :I

It's more like me looking at notes and wondering if how you'd be able to do something which wouldn't be examined?

Dat logic, explains why you smash economics :p

You should rather focus on what happens when the lorenz curve is 1 and how individuals/businesses/governments respond will increase your economic thinking :)

I'm all for students extending themselves beyond the syllabus, it really does assist in your extended responses if you understand MORE than is expected.

Re: Lorenz Curve

I guess you'd have to draw the line of inequality as far back as possible, which should demonstrate a gini co-efficient of about 0.95+

Re: Lorenz Curve

I would think it is a point at 100% cumulative income / 100% cumulative population, and a line along the population axis, not including the 100% cumulative population point.
