Wage as the Opportunity Cost of Free Time
In a work-leisure model, the wage rate is equivalent to the opportunity cost of an hour of free time. This is because the wage quantifies the amount of consumption an individual forgoes by choosing an hour of leisure instead of working. For instance, with a wage of €30 per hour, the opportunity cost of one hour of free time is €30 in potential consumption.

Calculating MRT for a Linear Feasible Frontier (y + z = 200)
An individual's feasible set of choices between two goods, 'leisure hours' and 'consumption units', is represented by a straight, downward-sloping line on a graph. Point A on this line represents a combination of many leisure hours and few consumption units. Point B, also on this line, represents a combination of few leisure hours and many consumption units. How does the number of consumption units the individual must sacrifice to gain one additional hour of leisure compare at Point A versus Point B?
Production Trade-Off Analysis
Interpreting a Constant Trade-Off
A producer's feasible combinations of producing two goods, widgets and gadgets, are represented by a straight, downward-sloping line. Two possible production points on this line are (100 widgets, 50 gadgets) and (120 widgets, 40 gadgets). What is the opportunity cost of producing one additional widget, in terms of gadgets?
A student has a fixed amount of time to allocate between two activities: studying and exercising. The relationship representing all possible combinations of hours spent on these activities is a straight, downward-sloping line. Suppose the student finds that giving up 1 hour of studying allows them to gain exactly 30 minutes of exercise. If they are already exercising a lot and decide to give up another hour of studying, how much additional exercise time will they gain?
Analyzing Production Scenarios
A decision-maker must choose between combinations of two items, 'Item X' and 'Item Y'. Match each graphical representation of their possible choices (their feasible frontier) with the correct description of the trade-off they face.
The Economic Significance of a Linear Feasible Frontier
A producer's feasible combinations for producing two products, Product A and Product B, are represented by the equation
5A + 2B = 200. To produce one additional unit of Product A, how many units of Product B must the producer forgo, assuming they remain on the frontier?Equivalence of MRT and Opportunity Cost on the Feasible Frontier

A graphic designer who is paid by the hour is currently earning €40 per hour. They are considering a new contract that would pay them €50 per hour. Assuming their available hours for work or leisure remain the same, how does this potential change in pay affect the graphical representation of their budget constraint between free time and consumption?

An individual's hourly wage for their job increases from $20 to $25. In a model where this person chooses between hours of free time and total consumption, and assuming free time is plotted on the horizontal axis and consumption on the vertical axis, what is the direct effect of this wage increase on their budget constraint and the opportunity cost of their free time?

Scarcity
Reservation Option
You have a free ticket to a concert tonight which you value at $50. You could, instead, work a shift at your job and earn $70, or you could babysit for a neighbor and earn $40. Assuming these are your only three options and you can only choose one, what is the opportunity cost of attending the concert?
Analyzing a Summer Decision
Evaluate the following statement: A person has three mutually exclusive options for their evening: 1) Go to a concert they value at $50, 2) Work a shift and earn $80, or 3) Read a book they value at $20. If they decide to work the shift, their opportunity cost is $70, representing the sum of the values of the concert ($50) and the book ($20) that they gave up. True or False?
For each economic decision described below, match it with the correct statement of its opportunity cost.

Explaining Opportunity Cost
A student has three mutually exclusive options for their Saturday afternoon: they can work a 4-hour shift at the campus library for $15 per hour, go to a movie with friends which they value at $40, or take a paid online survey that will earn them a total of $50. If the student chooses to work at the library, the opportunity cost of this decision is $____.
An individual has decided to spend their Saturday afternoon working a part-time job. To correctly identify the opportunity cost of this decision, they must follow a logical process. Arrange the following steps into the correct sequence.
The Baker's Dilemma
Alex is deciding how to spend their Friday night. They can either go to a movie, for which a ticket costs $12 and which they value at $30, or they can work a tutoring session and earn $40. These are Alex's only two options. What is the opportunity cost of choosing to go to the movie?

Evaluating a Work-Consumption Goal
A student is offered a job that pays €30 per hour. Assume the student can work a maximum of 16 hours per day. If the student is currently planning to work 9 hours per day but is now considering working only 8 hours instead, what is the most accurate analysis of the direct consequence of this one-hour change in their plan?
Calculating and Interpreting the Feasible Frontier
In a model where an individual determines their daily working hours based on a fixed hourly wage, their final decision on how to balance work and free time is influenced by the work-leisure choices of their peers.
An individual can devote their 24-hour day to either free time or work, earning a wage of €20 for every hour worked. Their earnings are spent entirely on consumption. Match each potential daily outcome (a combination of free time and consumption) with its correct classification based on what is possible within these constraints.
An individual has a job offer that pays €35 per hour. They are considering their schedule for a particular day where they could work for 8 hours. If this individual chooses to take the entire 8-hour period as free time instead of working, the opportunity cost of this decision, measured in terms of potential consumption, is €____.
Imagine you are building a simple economic model to represent an individual's daily choice between earning money for consumption and enjoying free time. Arrange the following steps in the logical order required to define the individual's complete set of possible outcomes (their 'feasible set').

Learn After
A student works part-time and currently earns a wage of €30 per hour. Suppose the student receives a promotion, and their new wage is €35 per hour. In the same week, they also receive a one-time scholarship payment of €100. What is the new opportunity cost for the student of taking one additional hour of free time instead of working?
Opportunity Cost of Study Time
An individual is offered a promotion that increases their hourly wage. As a result, the opportunity cost of taking an hour of leisure has decreased.
