The baked beans school of housing economics

There are various commentators, politicians and lobbyists who follow the baked beans school of housing economics.  In essence they believe that houses are like baked beans. If there are insufficient houses or you want prices to fall then you supply more. That’s what happens with baked beans so it’s the same for houses.

Baked beans oh same as houses!!
Baked beans oh same as houses!!
 
Followers of this school are oblivious to some rather critical differences between houses and baked beans.  Lets examine them. 
 
People do not:
1        Buy baked beans for uses other than eating.
2        Use baked beans as assets on the basis that their value will rise over time.
3        Low interest rates do not encourage people to shift money from bank deposits into buying baked beans.
4        Quantitative easing has never impacted on baked beans prices.
5        Banks do not lend money out so that people can borrow to buying baked beans in the process bidding up prices.
6        Foreign investors do not purchase baked beans to store their funds in.
7        Investors do not buy baked beans on a buy to let basis. 
 
A brief outline of why there is a housing crisis is set out below. For full details access:

The housing crisis the real cause – the multi-causal theory 
 

 
This discourse is more nuanced, essentially dismissing the supply as a major cause and instead is based on an understanding of how changes in housing finance policy, the relationship between interest rates and asset values and the effect of earnings on prices. We could call this the multi-causal theory or approach as it incorporates the various elements that determine changes in house prices and values and impact on affordability and access to housing. 
 
 
Why have house prices increased so much?
Deregulation.  Keen, 2025; Ryan-Collins, 2024.
Houses are different to most ‘goods’ in that they both provide a service – somewhere to live and are also an asset.  Lewis and Cumming, 2019; Miles and Monro, 2020; Mandelkern and Oren, 2025.
Investors purchasing property.  Ryan-Collins, 2024.
Growth of the Buy to let market.  Hamptons, March 2025. 
Earnings, Hantzsche, and Jeanes, 2025. 
 
Conclusion
As the multi-casual theory explains there are a number of elements, which together contribute to the rising house values. These are deregulation, increasing asset values as interest rates fell, quantitative easing and higher earnings.   Again changes in supply are not regarded as playing a significant role contrary to the views and assertions of many commentators and politicians. 
 
“It’s true that greater supply would reduce rents and prices marginally. But most academic work on the subject tells us that no plausible amount of building will have a material impact on either problem. Oversimplifying our housing problems is leading policymakers down a blind alley — only when we grasp the real causes will we have a chance of solving the housing crises.” [Mulheirn, 2018].
