If a good is normal, then this curve will have a positive slope; if the good is inferior, it will have a negative slope.
The inventor of this curve founded the first Mortgage Insurance Society during his time in Dresden. Antonelli and Nataf demonstrated that if individuals face the same prices in a market, then their instances of this curve would all be parallel with one another. Gorman later generalized this result to build such a curve for an entire society. If a good is normal, then this curve will have a positive slope; if the good is inferior, it will have a negative slope. For 10 points, identify this curve that plots the quantity of a good demanded against successively higher income levels.
