Towards a New Theory of Wealth

Executive summary

The literature does not support a single-cause theory of wealth. Classical political economy explains wealth through the division of labor, market expansion, and capital accumulation; neoclassical theory emphasizes marginal productivity, efficient allocation, and growth through capital, labor, and technology; Marxist theory reframes wealth as a historically specific social relation built through commodity production, accumulation, and class power; institutional and Austrian traditions focus on rules, property rights, dispersed knowledge, and entrepreneurship; the capability approach shifts attention from resources to what people are substantively free to do and be; behavioral economics shows that real wealth behavior is shaped by loss aversion, framing, heuristics, and status signaling; and ecological economics argues that wealth must be assessed relative to natural limits and the maintenance of the biosphere. Each tradition captures something essential, but none is sufficient on its own. citeturn32search1turn3search0turn4search0turn32search2turn6search2turn5search2turn7search3turn14search2

Recent evidence makes the need for synthesis more urgent. Global private wealth continued rising in 2024, with UBS reporting a 4.6% increase after 4.2% growth in 2023, while the World Inequality Report 2026 estimates that the global top 10% owns about three-quarters of wealth and the bottom half owns only 2%. At the same time, the World Bank’s wealth accounting shows that human capital is the largest component of national wealth, produced capital per capita rose strongly from 1995 to 2020, and renewable natural capital per capita fell by more than 20% over the same period. In other words, the world is becoming richer in some asset classes while also eroding part of its underlying productive and ecological base. citeturn18search0turn19search0turn20search1turn0search0

The most robust interdisciplinary result is that wealth is not merely a stock of financial claims. It is generated and reproduced through a portfolio of capitals and coordinating systems: human capabilities, knowledge and intangible assets, physical capital, legal and political institutions, social networks and trust, and ecological assets that support production and life. Corporate intangible assets alone were estimated by WIPO at about USD 97 trillion in 2025, while research by Chetty and coauthors and by Bloom, Sadun, and Van Reenen shows that social capital and trust affect mobility, decentralization, and productivity. Inclusive and accountable institutions, meanwhile, remain among the strongest predictors of durable prosperity. citeturn21search0turn10search3turn10search4turn11search0turn11search5turn24search0turn4search0

This report proposes a new theory of wealth centered on sustainable generative capacity: wealth is the stock of assets, capabilities, institutional arrangements, and ecological conditions that enable a population to generate valued functionings and resilient future possibilities over time. On this view, wealth is not equivalent to income, GDP, or private net worth alone. It is better understood as a dynamic, multi-capital, distribution-sensitive, and ecologically bounded system. That implies three major shifts for research and policy: measuring stocks as well as flows; distinguishing productive wealth creation from mere asset-price inflation and rent extraction; and evaluating wealth not only by aggregate size, but by durability, diffusion, and compatibility with ecological limits. This synthesis is grounded in the wealth-accounting literature, the capability approach, the OECD well-being framework, and environmental-economic accounting standards. citeturn20search1turn6search2turn15search3turn15search1turn15search4turn14search2

Conceptual foundations of wealth

Philosophically, modern wealth theory oscillates between three poles. The first is property-centered liberalism, associated with Locke, where secure rights over property and consent-based political order are foundational. The second is distributive justice, associated with Rawls, where inequalities are assessed by whether they benefit the least advantaged and preserve fair equality of opportunity. The third is capability-centered evaluation, associated with Sen and the human development tradition, where resources matter because they expand or constrain substantive freedoms. These philosophical traditions map imperfectly onto economic theories, but they clarify why “wealth” can mean ownership, welfare, power, security, opportunity, or freedom depending on the analytical lens. citeturn9search1turn9search0turn9search3turn6search0turn6search2

A useful way to read the history of the field is as a gradual widening of the concept of wealth: from productive stock, to utility-bearing stock, to social power, to institutionally enabled opportunity, to human capability, and finally to comprehensive wealth embedded in ecosystems. Theories did not simply replace one another; rather, they layered new dimensions onto old questions. The unresolved task is to build a framework that can jointly explain accumulation, allocation, distribution, legitimacy, and sustainability. citeturn32search1turn4search0turn6search2turn14search2

Interdisciplinary determinants of wealth

A serious wealth theory has to be interdisciplinary because the evidence is interdisciplinary. Institutions matter because they shape incentives, expectations, and the enforceability of claims. Acemoglu, Johnson, and Robinson argue that broad-based property-rights enforcement and constraints on power are central to long-run growth, while the World Bank’s Worldwide Governance Indicators explicitly frame governance as a major determinant of development outcomes and cover more than 200 economies through six dimensions, including rule of law, regulatory quality, and control of corruption. citeturn4search0turn24search0turn24search1

Technology matters because knowledge compounds and because modern wealth is increasingly intangible. Romer’s endogenous growth model treats knowledge as a non-rival input with increasing returns, while Aghion and Howitt formalize Schumpeterian creative destruction as an innovation process that both creates and obsoletes value. The empirical side has caught up with this theoretical shift: WIPO now estimates global corporate intangible asset values at roughly USD 97 trillion in 2025, around two-thirds of world GDP over the past decade on average. In practical terms, that means modern wealth creation increasingly depends on software, patents, data, organizational routines, brands, and know-how that conventional balance-sheet and national-income systems only partially capture. citeturn3search0turn13search0turn21search0turn12search0

Culture and social capital matter because wealth creation depends on trust, norms, and network structure, not just prices and endowments. Bloom, Sadun, and Van Reenen show that higher trust and stronger rule of law are associated with more decentralization, better reallocation, and higher productivity across firms and countries. Chetty and coauthors, using 21 billion Facebook friendships, identify measurable dimensions of social capital—economic connectedness, social cohesion, and civic engagement—and show strong associations with economic mobility. This does not mean culture is destiny. It means wealth creation is socially embedded: the returns to education, entrepreneurship, and innovation are partly mediated by the density and openness of networks. citeturn11search0turn11search5turn10search3turn10search4

Human capital remains indispensable. Becker’s foundational work framed education and skills as investments that raise productivity and earnings, and the World Bank’s Human Capital Project defines human capital as the knowledge, skills, and health people accumulate over their lives. The World Bank’s comprehensive wealth accounts go further, showing that human capital is the largest component of measured national wealth globally. A new theory of wealth therefore cannot treat labor as a homogeneous flow input; it must treat persons as bearers of capabilities that are productive, cumulative, and unequally distributed. citeturn3search1turn13search2turn20search1

Ecology matters because every economy is nested within biophysical systems. The Dasgupta Review argues that prosperity depends on managing nature as an economic asset, while the UN-backed Inclusive Wealth framework and the World Bank’s Changing Wealth of Nations account both insist that sustainability requires monitoring stocks of natural capital alongside produced and human capital. The planetary-boundaries framework now reports that multiple Earth-system boundaries have been transgressed, implying that some apparent wealth gains are financed by drawing down natural assets faster than they regenerate. In plain terms, a society can become richer in market value while becoming poorer in reproducing conditions of life. citeturn6search1turn14search2turn20search1turn14search0turn15search1

Empirical patterns in wealth creation and distribution

The global pattern is clear: wealth has increased, but it has increased unevenly and in forms that existing metrics do not fully reconcile. UBS reports that global wealth rose by 4.6% in 2024 after a 4.2% increase in 2023; over the past 25 years, total wealth rose at a compound annual rate of 3.4%. Yet the World Inequality Report 2026 estimates that the top 10% owns about 75% of global wealth, the bottom half only 2%, and fewer than 60,000 people—roughly 0.001% of the global population—control more wealth than half of humanity combined several times over. UBS also reports that the United States and mainland China together account for more than half of the wealth in its study and that the United States alone accounts for almost 40% of global USD millionaires. citeturn18search0turn18search3turn19search0

The composition of wealth is changing as much as its distribution. The World Bank’s Natural Capital Data Hub reports that between 1995 and 2020 produced capital per capita increased by 47%, human capital per capita increased by about 9%, nonrenewable natural capital per capita declined slightly, and renewable natural capital per capita fell by more than 20%. This is one of the cleanest empirical demonstrations that GDP growth and even some forms of asset accumulation can coexist with depletion of the underlying wealth base. citeturn20search1turn0search0

Selected official findings from major economies reinforce the point.

The driver side is equally important. The evidence most strongly supports a bundle explanation rather than a monocausal explanation. Innovation raises wealth where ideas can be financed, commercialized, and diffused. Property rights and governance matter where they broaden incentives rather than merely protect insiders. Human capital raises productivity, but only if labor markets, firms, and legal regimes can convert skills into earnings and innovation. Trust and network openness matter because they reduce transaction costs and permit delegation. Policy matters because taxes, public investment, competition rules, and asset-market design affect whether wealth accumulation is broadly productive or narrowly extractive. citeturn3search0turn13search0turn4search0turn13search2turn11search0turn24search0

One implication is especially important: wealth creation and wealth concentration are related but not identical processes. Asset-price booms can enlarge aggregate private wealth without proportionate gains in capabilities, resilience, or sustainability. Conversely, public investments in health, education, early childhood, and environmental restoration can raise comprehensive wealth even when they do not immediately inflate private asset prices. The OECD’s well-being framework, the Human Capital Project, and the comprehensive wealth literature all point in this direction. citeturn15search3turn13search2turn20search1turn14search2

Contradictions and gaps in existing theories

The first unresolved contradiction is between wealth as ownership and wealth as capability. Standard household net-worth metrics count assets minus liabilities, but they omit human capital, much of social capital, and many institutional assets. That is analytically useful for finance and distributional analysis, but it is too narrow for a theory of prosperity. OECD household net worth is explicitly a material net-worth concept, while human development and capability approaches focus on opportunities, agency, and functionings. A new theory of wealth has to relate these, not choose one and ignore the other. citeturn31search0turn20search2turn6search2

The second contradiction is between productive wealth creation and revaluation-led wealth appreciation. Existing theories often conflate the two. Yet Fed, ECB, and Statistics Canada data all show that changes in wealth can come from asset-price revaluations as much as from new saving or investment. This matters because some revaluations reflect genuine innovation and future cash-flow expectations, while others mainly redistribute claims across time and classes. A theory that cannot distinguish new productive capacity from capital gains and rent extraction will misread both growth and inequality. citeturn30search0turn17search1turn17search0

The third contradiction is between private wealth growth and public or natural wealth erosion. The World Inequality literature notes that countries can become richer while governments become poorer, and the World Bank’s wealth accounting shows that renewable natural capital has fallen in per-capita terms even as produced capital increased. GDP is a flow metric; it was never designed to measure the sustainability of the asset base. This makes it a poor sufficient statistic for wealth. citeturn19search1turn20search1turn0search0

The fourth contradiction is between equilibrium frameworks and evolutionary, networked, path-dependent wealth formation. Austrian, Schumpeterian, institutional, and behavioral traditions all stress disequilibrium processes: discovery, creative destruction, imitation, lock-in, and status competition. Much of the standard neoclassical apparatus is best at comparative statics, not at explaining how complex societies generate, diffuse, and politically contest wealth over time. citeturn5search2turn13search0turn4search0turn7search3turn34search0

The fifth contradiction is temporal. Existing theories are weak at integrating intergenerational transfers, public inheritance, and ecological lag effects into one framework. UBS projects more than USD 83 trillion of wealth transfers over the next 20 to 25 years, concentrated especially in the United States, Brazil, and mainland China. At the same time, natural depletion and climate damages operate on long lags. A theory of wealth that is not explicitly intertemporal will miss one of the century’s central dynamics: the interaction between inheritance, public debt, and ecological debt. citeturn18search0turn14search0turn6search1

These contradictions point to the same gap: the field lacks a unified framework that treats wealth as a multi-capital stock system whose value depends on institutions, distribution, and ecological feasibility, not just on market prices.

Core principles and a formal conceptual framework

The proposed framework in this report is a synthesis, not a replacement doctrine. Its core claim is:

Wealth is the socially organized stock of assets, capabilities, institutional arrangements, knowledge systems, and ecological conditions that allows a population to generate valued functionings sustainably and resiliently over time.

That definition implies six principles.

First, wealth is a stock, not a flow. GDP, income, and profits are flows; wealth is the underlying portfolio that makes future flows possible. This is the common insight behind comprehensive wealth accounting, inclusive wealth, household balance-sheet accounting, and natural capital accounting. citeturn0search0turn14search2turn31search0turn15search1

Second, wealth is multi-capital. At minimum, the relevant capital vector includes produced capital, human capital, natural capital, social capital, and institutional-public capital, with financial and intangible assets treated as claims on, or organizational encodings of, these deeper capacities. This is consistent with the World Bank, UNEP, OECD well-being resources, WIPO’s treatment of intangibles, and the social-capital literature, even though those literatures usually remain separate. citeturn20search1turn14search2turn15search3turn21search0turn10search3

Third, wealth is distribution-sensitive. A society in which wealth is highly concentrated may still be rich on average, but its effective social wealth can be lower if concentration suppresses capability formation, mobility, trust, competition, and political legitimacy. The empirical literatures on mobility, trust, and governance all support this. citeturn10search3turn11search0turn24search0

Fourth, wealth is institutionally mediated. The same endowments of natural resources or skills can produce sharply different results depending on legal order, state capacity, competition policy, and public investment. citeturn4search0turn24search0

Fifth, wealth is ecologically bounded. If a gain in produced or financial wealth requires uncompensated depletion of ecosystems or transgression of planetary boundaries, it is not sustainable wealth creation. It is partial conversion of one stock into another, often with hidden loss. citeturn6search1turn14search0turn15search4

Sixth, wealth is dynamic and generative. The key question is not only “how much wealth exists now?” but “what future capabilities, resilience, and welfare can this stock system reproduce?” This moves the theory beyond static ownership to a regenerative, forward-looking concept. citeturn6search2turn14search2turn20search1

A compact formalization is:

[
W_t = \frac{1}{N_t}\left(P_t + H_t + N_t^{cap} + S_t + I_t + J_t\right)
]

where (P) is produced capital, (H) human capital, (N^{cap}) natural capital, (S) social capital, (I) institutional-public capital, and (J) knowledge/intangible capital, all expressed in comparable accounting or latent-factor units. Financial net worth is not omitted, but is interpreted mainly as a valuation layer and claim structure over these underlying capacities.

Net sustainable wealth creation can then be represented as:

[
\Delta W_t =

\underbrace{Inv_P + Inv_H + Inv_J + Reg_N + Build_S + Reform_I}_{\text{generative additions}}

\underbrace{Dep_P + Erode_H + Deplete_N + Fragment_S + Capture_I}{\text{depreciation and extraction}} + \underbrace{Reval_t}{\text{market repricing}}
]

subject to ecological feasibility constraints and a social floor of capabilities. The analytical purpose of separating revaluation from generative additions is to distinguish productive accumulation from mere asset inflation.

Policy, measurement, and research agenda

A new theory of wealth changes policy priorities. It implies that the task of economic policy is not simply to maximize GDP or asset prices. It is to expand sustainable generative capacity. That requires protecting broad-based property rights and credible institutions, investing in human capital from early childhood through lifelong learning, sustaining open knowledge and competition ecosystems, strengthening bridging social capital, maintaining public assets and public services, and pricing environmental depletion so that financial gains do not masquerade as genuine wealth creation. The theoretical support for these priorities is broad even when schools disagree on other matters. citeturn4search0turn13search2turn12search0turn10search3turn15search3turn6search1

The most defensible measurement strategy is therefore a dashboard-plus-balance-sheet approach rather than a single index. GDP should remain, but beside it should sit: median disposable income, median net wealth, top wealth shares, public wealth, comprehensive wealth per capita, human capital, natural capital, social capital, and a capability/well-being dashboard. The OECD well-being framework, SEEA, the World Bank’s wealth accounts, and the Inclusive Wealth framework are already the building blocks for such a system. citeturn15search3turn15search1turn20search1turn14search2

Research agenda and datasets

The immediate research frontier is to connect stocks that are currently measured in isolation. The field needs integrated empirical work that links distributional wealth accounts, human capital, natural capital, social networks, public assets, and innovation data in a common framework. It also needs more work on decomposition: how much of wealth growth comes from saving, diffusion of innovation, resource conversion, inheritance, market repricing, and rent extraction, respectively. citeturn26view0turn20search1turn21search0turn10search3

The strongest near-term empirical designs are likely to be mixed-method: cross-country panels for macro structure, linked microdata for household and firm behavior, and network or place-based designs for diffusion and mobility. Historically informed identification strategies remain crucial because many core variables—institutions, trust, inheritance, ecological endowments—are endogenous and slow-moving. citeturn4search0turn11search0turn10search0turn14search2

Open questions and limitations

Some parts of the literature remain weaker than others. Comparable international measures of social capital, public wealth quality, and intangible assets are still less mature than GDP or household balance-sheet statistics. Wealth at the very top remains difficult to observe in all countries, and natural-capital valuation is still methodologically contested. The proposed framework should therefore be read not as a finished accounting system, but as a rigorous synthesis and a testable research program. citeturn0academia61turn31search1turn15search1turn21search0

The central conclusion nonetheless stands: a new theory of wealth should treat wealth as sustainable generative capacity, produced by interacting forms of capital, mediated by institutions and networks, distributed across persons and groups, and bounded by ecological reality. That framing fits the strongest evidence better than any one inherited school taken alone. citeturn20search1turn14search2turn24search0turn10search3turn21search0turn19search0
