The idea behind the course

A familiar place.
A new way to think.

Marginal Falls is the setting for the course, with its citizens, bakery, port, markets, and businesses returning as the economics develops. A decision about riverfront land introduces scarcity. An investigation introduces budgets. A bakery order introduces production and costs.

Buyers and sellers first make their own plans. Then they meet in the Town Square, where prices coordinate their choices. The final act changes the competitive setting and asks how the same economic logic works under different market structures.

The course builds the people behind the curves before bringing the curves together.
