Another reason is high demand in locations where offer is limited due to physical limitations. There’s always demand to live in Broadway, and offer can never catch up due to its physical limitations.
Nowhere in the economic theory there is a proposition stating that prices should fall below affordable levels, given enough competition.
Stop and think for a second. Someone in good health with a willingness to DIY and a sufficiently flexible schedule can literally build their own house from the ground up. It's a substantial time investment but not actually as much as you might think. Housing isn't very resource intensive compared to the rest of the modern economy.
The only possibilities I can imagine to explain unaffordable housing are broken regulations, critical levels of resource exhaustion, natural or man made disaster, and gross economic dysfunction.
Construction labor is quite expensive and so are the raw materials (and going up). Means there is a hard lower bound on cost and unfortunately it's not that cheap even if they built at zero profit (which nobody will).
In reality, those ideas do not apply to the housing market, esp. as there is no real competition; and because the demand is absolutely inelastic (if we are already applying in MBA-wording universe)
Also, that this is true you can see if you compare to housing markets which "are more free than the Australian"
Do you think, people will migrate to a city with an unaffordable housing (unaffordable for them)?
Unless you are living in North Korea, the competition is also there.
- inelastic means the demand is more or less independet of the price; you can't "just stop renting & living" if prices are going up, your options to bypass are highly limited -> therefore its called >inelastic<
Housing demand is less elastic than, let's say, potato demand, but it's not "absolutely inelastic" as you have said.
No. Why do you guys fall so easily for the "regulation" cliche?
The answer is far easier: unwillingness to invest.
Why are there investment funds willing to burn through tens of millions in stupid stuff like NFTs or pets.com, but investing $10m on a 5 story apartment building that can get you a solid RoI of 20% is frowned upon?
I know some people that are currently "willing to invest" in buying a ship container or two and transform it into a house to get costs down. The problem? Regulations don't allow them to put the container in their own property.
Sure you're free to go out into the middle of nowhere and build all sorts of wild stuff but there's no market for that because that isn't actually what anyone wants. You can't blame the investors when what people actually want to pay for has effectively been outlawed.
