Analysis of a Production Possibility

A farmer's feasible frontier shows the trade-off between tons of grain produced and hours of leisure per day. If this frontier is a downward-sloping curve that is bowed inward toward the origin (concave), what does this shape imply about the farmer's production process?

An individual's feasible frontier, showing the trade-off between daily consumption and hours of free time, is represented by a downward-sloping curve that is bowed inward toward the origin. This shape implies that the opportunity cost of an additional hour of free time, measured in terms of consumption given up, is constant.

Reasoning Behind a Concave Feasible Frontier

A student has 24 hours in a day to allocate between studying for an exam and free time. For every hour of free time they take, they lose an hour of study time. However, due to fatigue, each additional hour of studying results in a smaller increase in their final exam score than the previous hour. If the final exam score is on the vertical axis and hours of free time are on the horizontal axis, what is the shape of the student's feasible frontier?

Match each economic scenario describing a trade-off with the shape of the feasible frontier that represents it. Assume the first item mentioned in the scenario (e.g., 'leisure time') is on the horizontal axis and the second item (e.g., 'income') is on the vertical axis.

If an individual's feasible frontier for a trade-off (e.g., between goods produced or between leisure and consumption) is represented by a curve that is bowed inward toward the origin, it indicates that the opportunity cost of the item on the horizontal axis is ________ as more of that item is chosen.

Comparing Production Scenarios

A student is modeling the trade-off between their final grade in Economics and their final grade in Chemistry, given a fixed number of total study hours. The feasible frontier for this trade-off represents all possible combinations of grades they can achieve. Which of the following underlying assumptions about their studying process would produce a feasible frontier that is a curve bowed inward toward the origin (concave)?
