Evaluating an Argument about Consumer Preferences
A classmate argues, 'A rational consumer's preferences should be consistent. Therefore, if they are willing to trade two cookies for one glass of milk when they have many cookies and little milk, they should be willing to make the same trade when they have few cookies and a lot of milk. This implies their indifference curves should be straight lines.' Critically evaluate this argument. In your evaluation, explain why this reasoning is typically considered incorrect in standard consumer theory and describe the principle that governs the more common shape of an indifference curve.

Comparing Individual Time Preferences via Indifference Curve Slopes
A consumer is indifferent between two bundles of goods: Bundle A (10 slices of pizza, 1 can of soda) and Bundle B (3 slices of pizza, 4 cans of soda). Both bundles lie on the same smooth, downward-sloping, curved line that is bowed towards the origin. What does the shape of this line between points A and B imply about the consumer's preferences?
Analyzing Atypical Consumer Preferences
A consumer's preferences for coffee and croissants are represented by a standard indifference curve that is downward-sloping and convex to the origin. Coffee is plotted on the horizontal axis and croissants are on the vertical axis. Match each description of a position on the curve with the statement that best describes the consumer's willingness to trade at that position.
Explaining the Shape of an Indifference Curve
If a consumer's willingness to trade one good for another remains constant regardless of how much of each good they currently possess, the line representing all bundles of goods that provide them with the same level of satisfaction will be a straight, downward-sloping line.
Evaluating an Argument about Consumer Preferences
The characteristic shape of a typical indifference curve, which is bowed inward toward the origin and becomes flatter as one moves along it from left to right, reflects the economic principle of a diminishing ____.
A consumer's preferences for books (horizontal axis) and movies (vertical axis) are represented by a single, standard indifference curve that is downward-sloping and convex to the origin. The following four bundles of goods all lie on this same curve. Arrange these bundles in order from the point where the consumer is most willing to trade movies for books to the point where they are least willing.
An indifference curve, representing combinations of two goods that provide a consumer with equal satisfaction, is typically drawn as a curve that is 'bowed in' toward the origin (convex). Which of the following provides the best economic justification for this specific shape?
Imagine a consumer's preferences for two goods, Good X (on the horizontal axis) and Good Y (on the vertical axis), are represented by an indifference curve that is downward-sloping but bowed away from the origin (concave). What does this unusual shape imply about the consumer's behavior?
