Key formulas
Price Elasticity of Demand

Lerner Index
Measures monopoly power. L=0 in perfect competition; L=1 in pure monopoly.
Part 1 of 5

Worked example
Rent control set at €800/month when the equilibrium rent is €1,200/month. Ceiling is binding → landlords supply fewer flats, tenants demand more → shortage. If rent control were set at €1,500/month, it would be non-binding and have no effect.

Why is this the correct answer?
Eliminate any option that contradicts something stated directly in the lesson, then check which one actually follows from the rule you just learned. Tell me which option confused you and I'll point to the exact line.
Exam strategy
If you can explain why the wrong answers are wrong, you know the topic. Remembering the right one only gets you halfway.
