%X i show that continuous convex preference relations that have affine indifference curves do not have a concave representation if there are two indifference curves that are not parallel. in other words a preference relation with affine indifference curves that has a concave representation has a linear utility representation.
%K concave representation
%K concavifiable preferences
%K linear utility.
