Thanks for posting,

I understand your skepticism here, completely. However, we can actually prove (or come darn close to proving) that there will be a shortage of rental units in at least one municipality.
Let's start with what we know for certain, then layer in the conditionals as they apply.
FACT: There are many municipalities that have rent-control tenants in power.
FACT: In those particular municipalities, short-term gain determines what they enact/repeal.
FACT: Rent-control has a short-term gain - smaller rent increases.
From these facts, I can conclude that these municipalities we're talking about currently have rent-control, and the rent-control tenants in power will continue to vote to keep the rent control (since it has short term gain). Now, that means the rent-control is NOT a "strictly temporary measure"!
CONDITIONAL: If not strictly temporary, rent control has negative effects that include shortage.
Since these municipalities must have rent-control that is not strictly temporary, they must eventually hit that long run negative effect of a rental shortage!
Notice that there's no real chance, in these situations, that these rent-control tenants in power will ever vote to repeal, because we're told that
short-term gain is always what they'll vote for. Even if we actually hit the rental shortage, fixing it would probably be a
long-term gain, not a
short term gain. There will still ALWAYS be a
short term gain in the smaller rent increases, so that is always what they'll choose.
Surprisingly tough question for a #11. I'll blame the early preptest for that oddness. It's actually not a bad question, but it's harder than I'd expect for where it is in the section.
Does this help clear up a few things?
