Okay but Realpage has a decade of real pricing data that it can use to continue informing these rental companies and outside of them having extremely hard boundaries in their service this is just going to happen again.
This doesn’t do a whole lot to address the actual issue, and these companies aren’t going to stop colluding over a wrist slap like this.
Basically when somebody makes a pricing error on a decentralized cryptocurrency exchange there's a mob of automated arbitrage bots that try to trade against it. Who wins and actually gets to make the trade is mainly determined by how high of a transaction fee your bot is willing to pay.
You can win instantly by offering to trade with a transaction fee so high it almost wipes out all but a cent or two of the entire arbitrage profits, because nobody else will pay a higher fee.
Instead what happens is bots offer the lowest possible fee, then immediately increase their fee as soon as they see a competing bot try to take the trade with a higher fee. This results in the bot offering the highest fee changing every several milliseconds as the fee quickly grows.
The way Ethereum mining works, this results in the winning bot being randomly selected from among the set of bots "bidding" up the transaction fee: blocks are mined at random intervals of iirc about 20 seconds, and whoever had the highest bid at the time the next block is mined wins. <20 seconds of bidding is short enough that even with the bidding, the transaction fee doesn't get bid up particularly high, and the winner makes out with a highly profitable arbitrage trade.
By giving up a guaranteed win and instead rolling the dice against other bots, transaction fees stay low and everyone has a higher expected profit. It's coordination that happens without any communication between the participants and quite possibly the participants didn't realize they were in effect cooperating when they added the high speed bidding behavior to their bots.
However, that's not a systematic method for lower prices. It just prevents individual cases of price gouging.
There is enough turnover with new listings to find the market rate while preventing existing tenants from being screwed over by unreasonable prices.
Australia also almost entirely works off rentals owned by individuals who own 1-3 properties rather than corporate owners so no one landlord has any sway over the market.
(Unless the other party to the contract deliberately asks you in the contract to keep it quiet. But that's something you need to actively agree to.)
Alternatively we could keep the names private. A cryptographic solution would easily serve the need of authorities verifying the right person is in a place without identification, but good luck figuring out how to ensure the tenant has their keys somehow since in the US there are zero pieces of identification you can ensure every citizen has.
On that basis, the 'free market' should be called the 'free, competitive market' - without competition, it has little value. Businesses should be required to compete and to opeerate in competitive markets. Anything anti-competitive should be treated harshly.
I'm not sure I understand where you are going with this? Are you suggesting that a new product cannot enter a market without a number of simultaneous competitors?
If I want to roll out fibre to an area that doesn't have it, can I? If I want to build a fresh-produce store in a town that doesn't have one, then I need to find someone else to compete with?
Lots and lots of businesses operate as quasi-monopolies if you look hard enough. Especially in smaller and rural environments. Lots and lots of places have one gas station, one mechanic, one vet, one doctor, one diner and so on.
Your use of the word "require" seems difficult to implement. What if no-one wants to compete with me? If Apple stops making Macs, does MS have to stop making Windows?
(Seven has been experimentally determined, but I can't recall where.)
I can't quote the formula here, but HHI is, apparently, the sum of squared percentage market shares. Six equal-sized suppliers give an HHI of approximately 1,667, while seven give approximately 1,429—on opposite sides of the 2010 threshold.
Is that where you got the number?
If you have examples of such a company in other industries, please share.
Housing needs to be decommodified. It needs to stop being a retirement plan. We need to stop letting people hoard it. We need to stop subsidizing exurbs and making it illegal to build the kind of walkable communities people actually like. Case in point: Red Vienna [1].
As another commenter noted, this is in every industry. Utilities are a particularly bad one including telcos. All the best ISPs in the US are municipally owned. Chattanooga was the first really big poster child for this.
Privatization of all these things is just rent-seeking behavior.
So many of society's problems come down to housing being too expensive. Anything that makes it expensive needs to be stamped out and that includes RealPage as well as Airbnb/VRBO.
Hint: it has an international airport :)
Your comment is so outrage-focused that I’m not inclined to help you make your argument. I largely agree with your point, but dialing back the rhetorical pathos would make it more persuasive.
