Income Offer Curve

… a core term used in Economic Analysis and Atlas102


Haydon Economics (reference below) defines income offer curve as a line that depicts the optimal choice of two goods at different levels of income at constant prices.

Haydon Economics writes:

“The income offer curve is also known as the income expansion path. If both goods are normal goods, then the income expansion path will have a positive slope. … If we hold the prices of goods 1 and 2 fixed and look at how demand changes as we change income, we generate a curve known as the Engel curve. The Engel curve is a graph of the demand for one of the goods as a function of income, with all prices being held constant.”
