I don't know, seems like there are a lot more negatives regarding rent control than positives. (As I said, it doesn't even totally control prices for renters.)
The alternative is people literally not having a ◊◊◊◊◊◊◊ place to live. So...now what?
Ummm... you realize the study pointed out that rent control REDUCES the number of units available. So even fewer people have a place to live.
Lets touch on a few other things that this study examines as well. Like what happens when the rent burden gets too high, things like:
a too high rental burden can have devastating effects. When the rental burden is excessive, it prevents households from buying other goods and services, thus negatively affecting the quality of life. In extreme cases, it can lead to poverty and malnutrition. Therefore, it is important to guarantee the affordability of housing.
First of all, I never claimed that housing affordability was not a problem. The question is whether rent controls are the best way to handle the problem.
Things like zoning changes (that allow the construction of more multi-unit dwellings over single family homes, increasing housing supply), improved public transit (making it easier for low income people to commute from places that might be cheaper), direct subsidies for low income tenants, etc. would all benefit low income tenants, without causing housing supply to shrink.
Secondly, as I pointed out before (and which the study showed), rent control drives up prices of non-rent controlled units (some of which will see a sharper increases in rent prices as a result of the controls.) So you aren't necessarily "fixing" the issue of poverty/malnutrition, you are just shifting it from one group of people (those lucky enough to find a rent controlled unit) to people who don't have a rent controlled units (and who might be just as poor).
Your source goes on at one point to say:
Secondly, diminished residential mobility could be attributed to heightened tenure stability. Through rent regulation, this policy alleviates the financial strain of tenant households, consequently reducing the likelihood of eviction. Additionally, rent control legislation is often adopted simultaneously with rules protecting tenants from arbitrary removals. As a result, tenants remain in their residences for longer time, thereby boosting their satisfaction.
Well yeah, people are happy in their rent controlled unites. The problem is those who WANT to move into the area but cannot because there is no place to rent. Assuming they have stable employment and do not need to move at all.
The gist of the overall paper, after reading through the bulk of it, is that the author repeatedly says more\different types of studies need to be done to get an actual firm understanding of how rent control affects neighborhoods.
Ummm, so?
Yes, more studies are needed to understand the complete impact. But that doesn't mean we don't have enough evidence to have a broad idea of what happens under rent controls. Its like climate change... we obviously should study it to build the best models for the impact of global warming, but that shouldn't mean we dismiss it as "not a problem" just because people are looking into some of the specifics
It's stated that, depending on the policy, the negatives can be minimized as well.
Minimized but not eliminated.
At no point has my question been answered. Are the side effects of the policy better or worse than what is currently in place?
If the ONLY thing you want to focus on are the few people that manage to get a slot in rent controlled housing, and you do not care about anything else (including the quality of the housing)? I am sure you will think its "great".
If you care about people who AREN'T in rent controlled housing (those who might need to move to the area, those living in the area who aren't in rent controlled units who see their rental prices go up more than they would have otherwise), or if you care about the quality of the apartments people are renting? Then you will see that rent controls are a bad idea. Especially when you consider that the problems that rent control is supposed to fix can be addressed in other ways.
