Do rent controls actually help tenants in the long term?

Rent controls, sometimes, have the perverse effect of making the problem of scarcity and affordability worse.

The most recent example of this was seen in Argentina, where a series of stringent rental controls meant landlords preferred to keep their properties empty rather than rent them out and get locked in. At one point, nearly a fourth of Buenos Aires’ properties were left empty, driving home the maxim that good intentions do not work in markets as the latter have their own dynamic.
