Series: Political Economy of Housing and Real Estate in South Korea | Part 4/5 ← Part 3: The Myth of Homeownership — Anatomy of Real Estate Class Politics

1. Introduction: The Political Economy of "Just Increase Supply"

The oldest and most powerful rhetoric in South Korean real estate discourse is the claim that "increasing supply is the only answer." During center-left governments the framing was "regulation constricts supply"; during conservative governments it was "we must deregulate to increase supply." Only the framing changes; supply-centric thinking has reigned as a bipartisan common sense spanning the construction industry, the financial sector, the media, and the political class.

The problem is that this discourse systematically conceals what is being supplied and to whom, and who captures the rent generated in the supply process. When the government relaxes redevelopment regulations, raises floor area ratios (FAR), and builds new towns — where does the tens of trillions of won in excess profit flow?

This essay answers that question. In Part 1 we analyzed the origins of land prices (rent theory). In Part 2 we examined the pathways through which land values convert into money (financialization). In Part 3 we analyzed the ideology that activates the class politics of land values (the myth of homeownership). The subject of Part 4 is the superstructure of state, law, and urban planning that structurally props up all three. Whenever the state intervenes in the name of new towns, redevelopment, and development regulation, through which channels is the generated rent distributed, and to whom?

Central thesis: In South Korea's housing and real estate regime, "supply expansion" is another name for state-led rent transfers to the landed class.

2. Twenty Years of the Redevelopment Excess Profit Recapture System — The Ideal of Public Recapture of Development Gains and Its Neutralization

2.1 2006: "Returning Unearned Income to Society"

The Redevelopment Excess Profit Recapture System (hereafter the Recapture System) was introduced in September 2006 under the Roh Moo-hyun government. Its background was the surge in apartment prices in Gangnam redevelopment complexes during the early-to-mid 2000s. In Gangnam redevelopment complexes such as Eunma Apartments, premiums worth hundreds of millions of won attached merely from initiating redevelopment — clearly unearned income unrelated to any individual member's labor.

The institutional design was grounded in Article 122 of the Constitution: "The State may, in accordance with the provisions of law, impose restrictions and obligations necessary for the efficient and balanced use, development, and preservation of the land of the State — the basis for the production and livelihood of all citizens." This is the so-called public concept of land clause.

The core of the Recapture System was as follows: if the average excess profit per redevelopment union member exceeded the exemption amount (then 30 million won), a charge of 10–50% was levied on the excess and recaptured by the state. The intent was unambiguous: to return the enormous unearned income generated by redevelopment to society as social wealth.

2.2 The Political Economy of Deferral: A Decade of Vacancy (2008–2017)

Yet the Recapture System entered a path of neutralization almost immediately after its introduction. That process was a microcosm of South Korean real estate political economy, reenacted at every regime change.

Lee Myung-bak government (2008–2012): Implementation was deferred from 2009 to 2013. The official justification was "revitalizing the housing market," but the substance was regulatory evasion in response to pressure from redevelopment unions and the construction industry. Throughout the Lee administration the Recapture System existed as law but never actually operated.

Park Geun-hye government (2013–2017): The deferral was extended again in 2013 and then again in 2015. Consequently, for a full decade after its introduction, the Recapture System achieved not a single normal levy and became effectively dead-letter law. During this period, apartment prices in Gangnam redevelopment complexes rose two-to-three-fold between 2013 and 2017, yet the state recaptured not a single won of excess profit. "The law exists, but enforcement does not" — the archetypal pattern of South Korean real estate regulation.

2.3 The Moon Jae-in Government: Revival and Constitutionality

The Moon Jae-in government reinstated the Recapture System in 2018. On December 27, 2019, the Constitutional Court ruled it constitutional by a 6–2 vote (Constitutional Court press release 2019.12.27; Yonhap 2019.12.27; Chosun Ilbo 2019.12.28). The Court stated explicitly that "redevelopment excess profits arise not from the efforts or investment of the landowner but from social factors such as surrounding infrastructure improvement, population concentration, and urban development — i.e., unearned income."

The period during which the Recapture System actually functioned was effectively just over four years, from 2018 to 2022. Even during this period, however, litigation, resistance, and public relations campaigns by unions subject to the charges never ceased.

2.4 2023: Legislating Neutralization

The Yoon Suk-yeol government formalized its revision of the Recapture System in the second half of 2022, its first year in office. In September of that year, the government announced a real estate package raising the exemption threshold from 30 million won to 100 million won and expanding the assessment brackets from 2 million-won units to 7 million-won units. It was a scheme designed so that virtually no redevelopment complex would pay the charge.

The amendment passed through the legislative subcommittee of the National Assembly's Land, Infrastructure and Transport Committee on November 29, 2023, with the ruling and opposition parties agreeing on an exemption threshold of 80 million won and assessment brackets of 50 million won. On December 8, 2023, the revision to the Act on Recapture of Excess Profits from Redevelopment passed the National Assembly plenary session (Hankyoreh 2023.11.29; Yonhap 2023.11.29; Kyunghyang Shinmun 2023.11.29; Newsis 2023.12.8; Dong-A Ilbo 2023.12.8).

The main contents of the revision were:

  1. Exemption threshold: 30 million won → 80 million won (approximately 2.7 times)
  2. Assessment bracket unit: 2 million won → 50 million won (2.5 times expansion)
  3. Maximum deduction of 70% for long-term holding (20 years or more)

The practical effect of this revision is unambiguous. If excess profit per redevelopment union member is 80 million won or less, the charge is zero won; even above that, far less is owed than before. In short, the Recapture System no longer operates in most redevelopment complexes. Indeed, since 2024 only a handful of cases have resulted in actual charges. According to a Yonhap (2025.6.12) report, as of June 2025 the number of complexes nationwide expected to be assessed stood at 58 — and even for these, the scale of charges has been greatly reduced by the relaxed criteria.

As of 2025, reports continue that the Lee Jae-myung government is also considering further relaxation of the Recapture System (Daum 2026.4.28).

2.5 Lessons: The Political Economy of Regulation

The twenty-year trajectory of the Recapture System reveals a structural law of South Korean real estate political economy:

  • Institutional introduction (2006) → deferral (2009–2017) → brief operation (2018–2022) → legislated neutralization (2023–present)

What moved in this cycle was not the ruling party's color but the political power of the real estate asset class — redevelopment unions, the construction industry, and multi-homeowners. The Recapture System was born from the constitutional value of the public concept of land, yet its enforcement always retreated before the political counterattack of the real estate class. Over twenty years, the system operated normally for barely four years — and now even its legal husk has been replaced by relaxation.

The "supply expansion" discourse covers over this history: the narrative "regulation blocks supply → deregulate → supply increases" deletes from the agenda the questions of for whom regulation was lifted and to whom the value of the increased supply accrued.

3. Redevelopment of the First-Generation New Towns — Examining the Scale of Unearned Income

3.1 The 1990 Sales Price, the 2026 Market Price

The first-generation new towns (Bundang, Ilsan, Pyeongchon, Sanbon, Jungdong) were built between 1989 and 1996, with initial sales prices for 30-pyeong units around 50–60 million won. According to a JoongAng Ilbo report of 2019.5.14, in 1990 identical-size apartments in Bundang and Ilsan started at the same price of approximately 58 million won.

As of 2025–2026, actual transaction prices for 30-pyeong units in major redevelopment-promotion complexes within Bundang's pilot districts (the Seohyeon, Yangji, and Saetbyeol neighborhoods, among others) range from 1.7 billion to 2.3 billion won. That amounts to up to roughly 40 times the initial sales price in about thirty years. Comparable units in Ilsan rose approximately 4–10 times over the same period — a wide gap with Bundang, and the gap itself demonstrates the operation of differential rent I (location).

Let us ask the question: of this rise of some 2 billion won, how much did the owner create through their own labor? Aside from paying 58 million won in the 1990s to acquire the sales right, what did this owner do to make the apartment appreciate? The construction of subway lines nearby, road expansion, commercial development, the establishment of IT corporate campuses, the building of educational infrastructure — all of these were the products of state budgets and social labor. Yet the place to which the results accrued was not the state, nor society, but the individual owner's asset account.

3.2 The Special Act on Aging Planned Cities and Pilot Districts: Supply or a Gift?

The Act on Special Cases Concerning Maintenance and Support of Aging Planned Cities (the Special Act on Aging Planned Cities for short), enacted in April 2024, is the legal foundation for redevelopment of the first-generation new towns. The main benefits of the Special Act are:

  • Exemption from safety diagnosis (removal of the greatest barrier to ordinary redevelopment)
  • FAR raised to a maximum of 500% (a major expansion compared to the previous 200–300%)
  • Differentiated public contribution rates (Seoul Economy 2025; JoongAng Ilbo 2023)

In November 2024, each local government selected and announced its pilot districts. According to the Chosun Ilbo (2024.5.22), the scale totals 26,000 households: 8,000 in Bundang, 6,000 in Ilsan, 4,000 in Pyeongchon, 4,000 in Jungdong, and 4,000 in Sanbon.

On paper, the government frames this Special Act as "improving aging residential environments" and "expanding housing supply." Reality is the opposite. The safety diagnosis exemption and the 500% FAR cap constitute large-scale rent creation through the lifting of building regulation, and the primary beneficiaries of that rent are the existing owners. When the FAR rises from 250% to 500%, the total floor area that can be built on the same land doubles. The value of that additional floor area is the product not of the landowner's contribution but of public regulatory relaxation. To whom does this value accrue?

The answer emerges in the structure of union members' cost burdens.

3.3 The Paradox of Cost Burdens: Accounting for the Privatization of Development Gains

The core issue in first-generation new town redevelopment is the cost burden (additional cash contribution). According to the Dong-A Ilbo (2025.10.2) and Chosun Biz (2026.3.1), estimated cost burdens in Bundang redevelopment complexes range from at least 400–500 million won to as much as 700 million won depending on housing type.

On the surface, this cost burden is explained as "the construction cost borne by union members." But economically, it is an investment made to pre-empt the rent created by the FAR increase. When the FAR rises from 250% to 500%, a member surrenders an existing 30-pyeong unit and receives a new 30-pyeong unit. On top of that, the profits from the newly built general sale units, made possible by the increased FAR, are distributed to members. The cost burden is merely the entry fee for obtaining those profits.

Consider a concrete hypothetical scenario. Suppose Bundang Complex A is redeveloped from 1,000 households of 30 pyeong into 2,000 households of 30 pyeong. The 1,000 existing members pay the cost burden (400–700 million won) and receive a new 30-pyeong unit. The other 1,000 units are sold on the market as general sales. Assuming a future sales price of 100 million won per pyeong, the general sales generate revenue of 1,000 households × 30 pyeong × 100 million won = 3 trillion won. After deducting construction and financing costs, the remaining profit — hundreds of billions to trillions of won — accrues to the members.

A member who paid 500 million won as a cost burden but receives 1 billion won back through the distribution of general sales profits realizes a net gain of 500 million won. Whose labor produced that 500 million won? Rent created by the state's regulatory relaxation — the FAR increase — has been transferred into the account of an individual member.

That is precisely how "supply expansion" works. The state creates rent through deregulation, and that rent accrues to the landowner. The housing released to the market through general sales (this is the "increase in supply") is merely a byproduct of rent privatization.

4. The Political Economy of the Floor Area Ratio — For Whom Is Deregulation Intended?

4.1 The Mechanism of Rent Creation through the FAR

The floor area ratio (the ratio of total floor area to site area) is a core instrument of urban planning regulation. The higher the FAR, the more floor area can be built on the same land, and thus the more sales revenue can be generated.

From the standpoint of Marxist rent theory, raising the FAR is state-led creation of differential rent II. As examined in Part 1, differential rent II arises from the additional productivity differential produced by intensive additional investment of capital on the same land. Raising the FAR from 250% to 500% is an act by which the state licenses "you may invest twice as much capital on this land." The license itself creates rent.

Here is the decisive question: to whom should this rent accrue? A FAR increase is not a contribution by the landowner; it is an administrative act of the planning authority, a decision premised on the carrying capacity of social infrastructure (roads, water and sewerage, electricity, schools). Therefore, this rent ought justly to accrue to society. The Recapture System was designed precisely on that principle. That the Recapture System has now been neutralized means that the rent created by FAR relaxation accrues almost entirely to the landowner.

4.2 The Fiction of Public Contribution

The Special Act on Aging Planned Cities demands a "public contribution" in exchange for the FAR relaxation. In conventional redevelopment, the price of FAR relaxation was paid in kind: a portion of the land was gratuitously transferred to the local government (land donation) or rental housing was supplied.

But the Special Act brought a change: a scheme permitting cash payment instead of donated rental housing was introduced (Daum 2025). This is a significant turning point. In-kind public contribution at least returns something to society in the physical form of "public rental housing." Cash payment eliminates even that. Once a certain sum of cash is paid, the developer gains the freedom to privatize all remaining rent.

Moreover, although the public contribution rate is indexed to the size of the FAR increase, the rate constitutes from the outset only a tiny fraction of the rent increase. If the additional sales profit generated by raising the FAR from 250% to 500% is 1 trillion won, the public contribution amounts to tens of billions of won. More than 90% still accrues to the union members.

5. The Structural Chain of Development Gain Privatization

5.1 State → Landowner → Financial Sector → Tenant

The privatization of development gains operates through a chain-like circuit.

First, the state creates rent through FAR relaxation, safety diagnosis exemptions, and tax reductions — under the public justification of "supply expansion."

Second, this rent accrues to the landowner (union members and multi-homeowners). The Recapture System has been neutralized, and public contributions are symbolic.

Third, the financial sector extends additional loans secured by the elevated asset values. When apartment prices rise, collateral values rise, and borrowing capacity increases. This reignites the MBS–jeonse–household debt circuit analyzed in Part 2.

Fourth, the elevated apartment and jeonse prices are passed on to tenants and housing-cost-burdened youth as housing expenses. Behind the PIR of 13.9 times, the youth homeownership rate of 12.2%, and the 36,950 jeonse fraud victims analyzed in Part 3 lies this circuit.

5.2 The Historical Retreat of the Public Concept of Land

In December 1989, the Roh Tae-woo government enacted the "three laws on the public concept of land": the Housing Site Ownership Ceiling Act, the Development Gain Recapture Act, and the Land Excess Profits Tax Act. Immediately after they took effect on January 1, 1990, the nationwide land price increase rate plummeted from 32.0% in 1989 to 20.6% in 1990 and 12.8% in 1991 (verified in Part 1). The institutions were working.

In 1994, however, the Constitutional Court ruled the Housing Site Ownership Ceiling Act unconstitutional, and amid the 1998 IMF foreign exchange crisis and the deregulatory orientation of the Kim Dae-jung government, it was effectively abolished. The Land Excess Profits Tax Act was likewise abolished following an unconstitutionality ruling in 2001. What survived was only the Development Gain Recapture Act (development charges), and even that had its teeth pulled by a succession of deductions and exemptions after the 2000s.

As of 2026, no functioning system for recapturing development profits actually exists in South Korea. What remains is only the institutional channel for the privatization of ground rent.

6. The Ideological Function of Supply Discourse

6.1 Why "Supply Expansion" Became "Common Sense"

The "supply expansion" discourse is so powerful in South Korea because it operates not as a mere policy preference but as ideology. Consider several mechanisms.

First, the dominance of the supply–demand schema: when the housing question is reduced to the elementary economics schema of supply and demand, rent, class, property systems, and power vanish from view. The logic that "it is expensive because supply is insufficient → increasing supply will make it cheaper" sounds plausible. In reality, however, the additional supply first raises the rent accruing to landowners, next increases the profits of construction companies, and only last produces a limited and delayed effect in lowering the entry cost for new entrants.

Second, the appearance of class neutrality: "supply expansion" appears to take no one's side. The narrative is that construction companies benefit, landlords benefit, and even non-homeowners benefit. That appearance of neutrality is precisely the most effective ideology—even though the benefits of supply expansion are in fact distributed along class hierarchies.

Third, the politics of visible results: groundbreaking ceremonies for new towns, completion ceremonies for reconstruction projects, and announcements of move-in supply are all visible achievements that the media can photograph and politicians can claim as their own accomplishments. By contrast, rent taxation, ownership regulation, and the expansion of public rental housing are invisible, invite political backlash, and take a long time for results to accumulate as measurable statistics. In a democratic political market, it is obvious which policies will be chosen.

6.2 Is It a "Supply Shortage" or a "Distorted Attribution of Supply"?

A more fundamental rebuttal is this: according to the National Data Agency's 2025 Social Indicators of Korea (published March 31, 2025), the national housing supply ratio stood at 102.9% in 2024 (news1, 2025.3.31). Even the capital region reaches 97.3%. The population is declining while the number of dwellings exceeds the number of households. There is no housing shortage in the physical sense.

If "supply shortage" is nonetheless the problem, it is not a physical shortage but a distributive distortion in which particular classes monopolize housing in specific regions, of specific types, and in specific price brackets. The reason housing in Gangnam's four districts and in Yongsan does not reach the hands of Seoul's non-homeowning youth is not a lack of supply, but that those units are locked up as accumulation vehicles of the asset-owning class.

The "supply expansion" discourse does not say this—because it cannot. The moment it did, the class interests it conceals would be exposed.

7. Conclusion: Beyond the Myth of Supply — Questions for the Socialization of Development Profit

Across four installments, we have analyzed the four-story structure of the political economy of housing and real estate in South Korea:

  • Floor 1 — land (theory of rent): Land prices are not natural but the product of social relations—differential rent, absolute rent, and class-monopoly rent.
  • Floor 2 — finance (jeonse, MBS, household debt): Jeonse converts the tenant's lump-sum deposit into the landlord's leverage, and the state underwrites it with MBS.
  • Floor 3 — ideology (myth of homeownership): The illusion of the owner-occupancy rate, jeonse fraud, youth housing poverty, and asset polarization are the underside of the myth.
  • Floor 4 — superstructure (regulation, law, planning): The state creates rent through deregulation, while recapture mechanisms such as the reconstruction excess-profit recapture system have already been neutered.

On this four-story structure, the slogan "supply expansion" translates as follows: "The state will create more rent and hand it over to the landowning class."

The questions this analysis must open up are obvious. Whose are development profits? To whom should the rent created by the state be attributed? What principle justifies the privatization, by individual owners, of trillions of won in value generated by increased floor area ratios, deregulation, and tax concessions?

In installment 5, we will seek alternatives for answering these questions. We will turn decommodification, public rental housing, and the reconstruction of the public concept of land into concrete policy tasks, and explore political paths for reorganizing housing as a right rather than as a commodity.
