Suboptimality of Intersection Points ('Could Do Better' Scenarios)
Points where an indifference curve intersects the feasible frontier represent choices that are feasible but suboptimal. These are often referred to as 'could do better' scenarios because the individual can increase their utility. At an intersection point, the marginal rate of substitution (MRS) is not equal to the marginal rate of transformation (MRT), indicating an imbalance in trade-offs. By moving along the feasible frontier towards the point of tangency, the individual can reach a higher indifference curve and thus achieve greater satisfaction. For example, the intersection points on Karim's IC1 and IC2 are suboptimal because he can reach the higher IC3.

Comparing Graphical Slopes to Determine Relative MRS and MRT
A consumer is choosing between consuming apples and bananas, and their current consumption bundle is on their budget line. At this specific bundle, the consumer's personal willingness to trade apples for bananas is higher than the market's price ratio of apples to bananas. To achieve a higher level of satisfaction while staying within their budget, what should the consumer do?
Analyzing a Production Choice
Consider an individual's choice between two goods, constrained by a feasible frontier. If their current consumption bundle is located at a point where their indifference curve intersects (crosses) the feasible frontier, they cannot achieve a higher level of satisfaction and should not change their consumption.
Analyzing Consumer Choice Inefficiency
An individual is choosing between two goods, represented on a standard graph with a feasible frontier and a set of indifference curves. Match each description of a consumption point to its correct economic implication.
Evaluating a Consumption Choice
When an individual's combination of two goods lies on their feasible frontier but their indifference curve intersects (crosses) the frontier at that point, the choice is considered ________ because a higher level of satisfaction is attainable by reallocating resources along the frontier.
An individual is currently consuming a bundle of two goods where their indifference curve intersects their feasible frontier. Arrange the following steps in the logical order they should follow to move from this suboptimal point to their best possible, utility-maximizing choice.
Analyzing a Student's Time Allocation
An individual is choosing between two goods, with their options limited by a feasible frontier and their preferences shown by indifference curves. If their current choice is a point on the feasible frontier, under which of the following graphical conditions is this choice feasible but suboptimal, meaning they could increase their satisfaction by moving to a different point on the frontier?
