In New York City, some apartments are under strict rent control, while others are not. This is a theme in many novels and movies about New York, including Bonfire of the Vanities and When Harry Met Sally. One predictable side effect of rent control is the creation of a black market. Let’s think about whether it’s a good idea to allow this black market to exist.
a. Harry is lucky enough to get a rent-controlled apartment for $300 per month. The market rent on such an apartment is $3,000 per month. Harry himself values the apartment at $2,000 per month, and he’d be quite happy with a regular, $2,000 per month New York apartment. If he stays in the apartment, how much consumer surplus does he enjoy?
b. If he illegally subleases his apartment to Sally on the black market for $2,500 per month and instead rents a $2,000 apartment, is he better off or worse off than if he obeyed the law?
