What Economics Studies

The idea
Economics studies how people choose when they cannot have everything. Individuals, households, firms and governments all face that problem.
In practice
A student picks courses, a firm picks products, a government picks a budget.
Where people slip
Economics is a set of questions and tools, not a list of facts; it lights up the choices without dictating the answer.
