Marginal Changes
In economics, a marginal change quantifies the impact of a small, incremental adjustment to a variable. When two variables, and , are related by a function , the marginal change is represented graphically by the slope of the function. For continuous functions, this change is precisely measured using the function's derivative. [1, 2] This use of derivatives is a standard technique for measuring marginal changes throughout all mathematical extensions in economic analysis. [3]

A student has a non-refundable, pre-paid ticket to a concert tonight that cost $50. A friend offers them a last-minute babysitting job for the same evening that pays $70. The student cannot do both. If the student's only two options are to go to the concert or to babysit, what is the opportunity cost of choosing to go to the concert?

A chemical factory operates near a river, producing a valuable product that is sold nationwide. As a byproduct of its manufacturing process, the factory discharges waste into the river. This significantly reduces the fish population, harming the businesses of local fishing companies that rely on the river. The factory does not compensate the fishing companies for this damage. This uncompensated impact on the fishing companies is a classic example of what economic concept?
A city government has a fixed annual budget and must decide how to allocate its funds. The city council wishes to build a new public library, upgrade the water treatment facility, and repave several major roads. The combined cost of these projects is greater than the total budget available. The necessity of choosing which projects to fund and which to postpone is a direct result of what fundamental economic concept?

An individual places $1,000 in a savings account that yields a 1% annual interest rate. During the same year, the economy experiences an overall price increase of 3% for goods and services. At the end of the year, what has happened to the purchasing power of the individual's savings?
Evaluating a Congestion Charge Policy
A government decides to increase its spending on public infrastructure projects, such as building new roads and bridges. To finance this, the government increases the tax on gasoline. As a result of this decision, the government has fewer funds available to upgrade the national park system. Which of the following core economic concepts is LEAST directly illustrated by this scenario?

A coffee shop is considering staying open for an additional hour, from 4 PM to 5 PM. The table below shows their total revenue and total costs for different hours of operation. Based on an analysis of the change from the 4th to the 5th hour, what is the most logical decision and why?

Decision on Studying
A software company has invested $5 million in developing a new product. Due to unexpected competition, the projected future revenue from the product has dropped to $3 million. The company estimates it will cost an additional $1 million to complete the product. Based on a rational analysis of incremental changes, the company should abandon the project because the total cost ($6 million) will exceed the total revenue ($3 million).
Marginal vs. Average Analysis in Decision-Making
A rational decision-maker thinks at the margin by comparing the additional benefits and additional costs of a small change. For each scenario below, match it with the correct marginal comparison that should guide the decision.
Rational individuals make decisions at the margin. This means they will choose to take an action only if the additional, or marginal, benefit of the action is at least as great as the marginal ____.
A firm is considering whether to produce one additional unit of a good. Arrange the following steps in the logical order a rational decision-maker would follow when thinking at the margin.
