# Offer curves for giffen good [closed]

I learnt that giffen good doesn't satisfy the law of demand, but can we draw an offer curve to represent giffen good?

• Yes, that is possible, both for a price and an income offer curve. What exactly is your question? May 27 at 19:10
• Also, you have a lot of answered questions; consider accepting some answers. May 27 at 19:12
• @Giskard-How would it look like? Any reference points? The internet is filled with interior and normal, haven't encountered any example highlighting the case of giffen good. PS I just accepted some of the answers.

• How would what look like? Price offer curve or income offer curve? And will you be satisfied with just a graph? May 27 at 19:47
• Price offer curve.. a graph should be fine :)

Below is a graph of the price offer curve of good $$y$$ when income is $$48$$ units, $$p_x = 8$$ and the utility function is $$U(x,y) = \min\left(2x+2y,x+10\right).$$ (Based on "Simple Utility Functions with Giffen Demand" by Sørensen).
Good $$y$$ exhibits Giffen behavior when $$0 < p_y < 8$$.
A gif of the optimal choice changing as $$p_y$$ changes is presented below (budget set is grey, indifference curve and optimal bundle are green, income-offer curve is orange dashed line):
