Questions and Answers

According to the provided content, what is a key difference between students in the context of their feasible frontiers and indifference curves?

Students have different feasible frontiers, but similar indifference curves.
Students always choose the same optimal point on the feasible frontier because all have identical preferences.
Students have similar preferences, leading to similar shapes and slopes of their indifference curves.
Students have identical feasible frontiers, but potentially different indifference curves due to varied preferences. (correct)

What condition describes where Alexei will make his optimal choice?

The point where indifference curves intersect the feasible frontier.
The point where the marginal rate of substitution is less than the marginal rate of transformation.
The point where the marginal rate of substitution equals the marginal rate of transformation. (correct)
The point where the marginal rate of substitution is greater than the marginal rate of transformation.

If point C is below the feasible frontier and point D is on the feasible frontier, what can be inferred about Alexei's potential optimal choice?

Alexei might choose point C because it offers more of both free time and grade options.
Alexei will always prefer point C because it is below the feasible frontier.
Alexei could choose either point C or D as they offer the same level of utility.
Alexei might choose point D as it is on the feasible frontier, while point C is suboptimal. (correct)

Considering students with downward-sloping indifference curves, what is implied about the optimality of point E?

Flashcards

Optimal Choice

The point where an individual's indifference curve is tangent to their feasible frontier, representing the optimal choice.

Marginal Rate of Substitution = Marginal Rate of Transformation

The rate at which an individual is willing to trade one good for another (marginal rate of substitution) is equal to the rate at which one good can be transformed into another (marginal rate of transformation).

Downward-Sloping Indifference Curve

If an individual's indifference curve is downward sloping, they prefer more of both goods. However, the optimal choice depends on the individual's specific preferences, not just the shape of the curve.

Ratio of Final Grade per Free Time

This ratio indicates the productivity of an individual's time allocation. It's not necessarily the optimal choice as individuals have different preferences.

Feasible Choice

A feasible choice represents a combination of goods that is attainable given an individual's resources and constraints.

Study Notes

Optimal Choice for Alexei

Alexei will choose a point where the marginal rate of substitution equals the marginal rate of transformation.
Point D, on the feasible frontier, is a potential optimal choice for Alexei, as it is on the frontier, unlike point C, which is below it.
All students with downward-sloping indifference curves (regardless of their specific slope) would select point E as their preferred option.
Point E maximizes the ratio of final grade to free time per day for Alexei.
