Every economic question begins with limited resources and unlimited wants. This unit gives you the vocabulary, the assumptions and the first models you will use all year.
Prices are not set by decree; they emerge. You learn to derive, shift and read curves, and to predict what a policy will actually do.
You switch to the firm's side of the market and ask how output decisions are actually made. Cost curves are the bridge to every later topic in microeconomics.
