Land, Housing and the British Economy (Muellbauer, 2026)

Summary

"Land, housing and the British economy," by John Muellbauer (Nuffield College and INET Oxford), appeared in the Journal of the British Academy 14(3), article a22, on 21 September 2026, open access. It is based on his British Academy Keynes Lecture at Bristol on 19 November 2025; a longer background paper is INET Oxford Working Paper 2025-25.[1][2] The article synthesizes other authors' studies, plus one calculation of his own, around a single thesis: changes to land-use, financial and tax institutions in the 1980s produced high and volatile land prices, and those prices diverted credit from productive investment, damaged growth and raised financial-stability risks.[1, abstract]

It also supplies what his shorter paper, Muellbauer: Property Tax Reform in England (WP 2026-24), leaves out: that paper never discusses land value, and the land value tax reasoning behind his position is here.

The Argument

The 1980s institutional turn. Muellbauer lists seven institutions inherited in 1979 (planning, New Towns, council housing, building standards, rent controls, mortgage credit controls, Domestic Rates) and says all but planning were changed radically in the 1980s.[1, pp. 5-6] The sequence includes mortgage deregulation, the sale of council homes (Right to Buy), the abolition of Development Land Tax in March 1985, and the pre-announced replacement of Domestic Rates by the Poll Tax. On the tax, citing Gibson (2025), he writes that abolition "probably contributed" to the 1985-89 boom.[1, pp. 6, 8] See Betterment Levy.

Land share and price volatility. Using ONS household balance-sheet data, he reports that "around 70 per cent of the value" of an average British house is land rather than structure; OECD national-accounts data show the UK highest in the G7.[1, p. 9] Footnote 14 concedes the share depends on building-depreciation conventions, but argues international comparisons are little affected. UK real house prices have risen about 300 percent since 1982, the most in the G7 (OECD).[1, Fig. 1] He infers larger rises in land prices because building costs are comparatively stable.[1, pp. 3-4, 10] That is an inference, not a measured land-price series.

Crowding out. The article relays a body of evidence that credit-fuelled real-estate booms displace productive investment: Müller and Verner's 116-country panel (1940-2016); Doerr (2020); Chakraborty, Goldstein and MacKinlay (2018); Grjebine, Héricourt and Tripier (2023), whose 14-country panel finds productivity losses in the UK, Ireland, France and Spain; and the Hirano and Stiglitz (2025) model (see Hirano and Stiglitz). For the UK, NERA (2024) estimates that a 1 percent fall in the house-price-to-income ratio raises local productivity by 0.14 percent, and Homes England (2025) 0.31 percent for London and the greater South East.[1, pp. 10-11] These are Muellbauer's relays of the studies, not independently verified. In his words, such booms "crowd out more productive investment."[1, p. 10]

The Affordability Decomposition

Using an elasticity of 1.8 of house prices to real household income relative to the housing stock, taken from Duca, Muellbauer and Murphy (2021), he reports that 63 percent of the rise in UK real house prices from 1980 to 2025 is accounted for by that ratio.[1, pp. 15-16][4] Two cautions apply. The 63 percent is a decomposition on an assumed elasticity and a particular specification, and it should not be paraphrased as "supply explains 63 percent." And he notes that over 1995-2018 only about half of price growth is explained this way, the rest reflecting interest rates and credit conditions.[1, p. 16] A 1 percent rise in the housing stock, roughly a year's residential investment, would lower real prices only 1.8 percent, so he argues a sustained period of higher building is needed.[1, p. 16]

Social housing is the second strand. By 2006, 2.8 million council homes had been sold, around half the stock; the social-rented share fell from 29 percent (1979) to 16 percent (2022-23).[1, pp. 13, 17] Housing-related benefits cost £26.8 billion in 2021-22 (Chartered Institute of Housing).[1, p. 13]

The Policy Package

Muellbauer proposes four parts that he argues work better together.[1, pp. 17-22]

• Planning reform. Drawing on Cheshire and on Watling and Breach, a flexible zoning code with guaranteed permission for compliant proposals; Auckland's 2016 upzoning as an example; community land trusts.[1, p. 18]
• Land value capture. Defined as securing for the taxpayer most of the land-value increase from planning permission and infrastructure. He recommends further reform of the Land Compensation Act 1961 to reduce "hope value" in compulsory-purchase compensation (see Hope Value) and to widen who may use such powers, tougher Section 106 affordability conditions, higher build-out rates, and public land in the fiscal net-worth rule. He says capture is "stalled."[1, pp. 18-19, 21]
• Social housing. Citing the National Audit Office (2022), a long-run return of £2.70 per £1 invested, as relayed.[1, p. 19]
• Property-tax reform and a green land value tax. A Green LVT combines a charge on land with a charge on buildings, offset by a discount tied to carbon emissions.[1, pp. 20-21] The background paper adds that land prices are more volatile than building costs and land is more unequally held than property, and lists two objections to a pure household LVT: buildings drive emissions, and the Mirrlees Review treats housing as a durable consumption good.[2, §6.4] It sketches a five-year phased transition (WP 2025-25, §6.5). As a feasible short-term goal he proposes a proportional property tax with green discounts plus a land tax on high-value unbuilt and agricultural land, for example above £40,000 per hectare, backed by registration of land options at the Land Registry.[1, p. 21] An equity-style deferral would charge 0.5 percent to payers and 0.6 percent to deferrers, reaching about 6 percent of sale value after ten years.[1, p. 21]

Relation to the Georgist Case

The article is a mainstream macroeconomist's statement of the land-as-factor argument, and cites Ryan-Collins, Lloyd and Macfarlane for it in the conclusions.[1, p. 21] The land-credit mechanism is treated under financialization of land. The efficiency case for taxing unimproved land rests on the OECD (2022) point relayed on p. 20 and on the Mirrlees Review; the incidence and price effects of such taxes are covered under tax capitalization, and capture instruments under land value capture. The idle-land tax is aimed at build-out; see the Letwin Review and United Kingdom.

Nuances and Limits

• Recommendations are advocacy. None of the four parts is tested in the article, and the Green LVT has not been implemented.
• Interpretation, not demonstration. That the Thatcher-era reforms caused the post-1980 record is the author's interpretation, and the framing ("largely for the worse") is his. Footnote 15 itself cites Maclennan and colleagues (2021) that the productivity literature cannot reliably attribute causality across channels.
• Relayed evidence. Figures from NERA, Homes England, the NAO and the Chartered Institute of Housing are as cited by Muellbauer.
• Self-citation weight. He authored the background paper and several works he relies on (Muellbauer 2018, 2023, 2024; Duca, Muellbauer and Murphy 2021).
• Land separation is hard. He acknowledges planning-induced land-value differences complicate separating land from building value, and argues automated valuation has improved.[1, p. 21]
• Supply is contested. He rejects Mulheirn (2019), who finds no supply problem, and says Miles and Monro (2021) overstate the interest-rate channel.[1, pp. 15-16]
