What Happens When Economic Models Account for Wellbeing Not Just GDP

To understand what revising economic metrics means, it is necessary to understand how completely GDP has come to dominate not just economic analysis but political culture. GDP growth is treated, in the public discourse of virtually every country, as the primary index of governmental success. Elections are won and lost on GDP growth rates. Central bank mandates, fiscal rules, and development finance frameworks are all built around GDP as the primary measure of economic success.

This was not inevitable. The national income accounting frameworks developed by Kuznets in the United States, Colin Clark in Britain, and Jan Tinbergen in the Netherlands in the 1930s-40s were designed to help governments understand the productive capacity of their economies and manage the macroeconomic problems of depression and war mobilization. They were not designed to measure welfare, and their designers said so explicitly.

The transformation of GDP from a management instrument into the primary index of societal progress happened through a combination of institutional path dependence (once you have a metric, you build systems around it, which makes changing the metric costly), geopolitical function (GDP growth became a key metric of Cold War competition, with both the United States and the Soviet Union using economic output as a measure of ideological success), and intellectual convenience (GDP is measurable, comparable across countries, and updatable quarterly — properties that metrics of wellbeing or sustainability often lack).

The result is a metric that has achieved a kind of unquestioned authority that its architects did not intend and would not have endorsed. Robert Kennedy's 1968 speech criticizing GDP remains one of the most eloquent articulations of the problem: "Gross National Product counts air pollution and cigarette advertising, and ambulances to clear our highways of carnage... It counts napalm and nuclear warheads and armored cars for police who fight riots in our streets... Yet the gross national product does not allow for the health of our children, the quality of their education or the joy of their play... it measures everything in short, except that which makes life worthwhile."

The revision of economic metrics has proceeded along several distinct intellectual and institutional tracks, each generating different frameworks with different properties.

Dashboard Approaches. The earliest responses to GDP inadequacy were dashboard approaches: rather than replacing GDP with a single alternative measure, maintain GDP while adding a set of supplementary indicators that capture dimensions GDP misses. The OECD's Better Life Index (2011), covering eleven wellbeing dimensions (housing, income, jobs, community, education, environment, civic engagement, health, life satisfaction, safety, work-life balance) and the UN's Human Development Index (HDI, 1990), covering income, education, and life expectancy, are the most widely used examples.

Dashboard approaches have the advantage of not requiring agreement on how to weight different dimensions of wellbeing — a politically and philosophically difficult problem. They have the disadvantage of producing complex, multi-dimensional pictures that do not generate the single headline number that political communication requires. In practice, GDP retains its headline status while the supplementary indicators receive attention in academic and specialist circles.

Composite Indices. The HDI was an early attempt to collapse multiple dimensions into a single index. More recent composite indices include the Social Progress Index (measuring basic human needs, foundations of wellbeing, and opportunity), the Genuine Progress Indicator (adjusting GDP for income distribution, environmental costs, and unpaid work), and the Inclusive Wealth Index (measuring produced capital, human capital, and natural capital).

Composite indices require explicit weighting decisions — choices about how much to value health versus income, or present versus future wellbeing — that dashboard approaches avoid. These choices are inherently political and can be contested. But composite indices are more politically usable than dashboards because they produce rankings and comparisons that generate news.

Natural Capital Accounting. The most technically demanding revision is the attempt to incorporate natural capital — the stock of natural assets from which humanity derives ecosystem services — into national accounting systems. This requires estimating the economic value of services like clean water, carbon sequestration, pollination, flood protection, and biodiversity that are provided by ecosystems but do not appear in market transactions.

The UN System of Environmental-Economic Accounting (SEEA), adopted by the UN Statistical Commission in 2012 and extended in 2021, provides a framework for tracking natural capital alongside conventional economic accounts. The Dasgupta Review (2021), commissioned by the UK Treasury, provided a comprehensive intellectual framework for incorporating biodiversity into economic reasoning, arguing that conventional economic models that treat natural capital as inexhaustible inputs or external constraints are structurally misspecified and will produce systematically bad policy.

Wellbeing-First Governance. The most radical institutional revision has been the attempt to embed wellbeing frameworks into government decision-making as primary rather than supplementary criteria. New Zealand, Scotland, Wales, Finland, and Iceland are the most prominent examples, having established the Wellbeing Economy Governments (WEGo) partnership to share approaches.

New Zealand's Wellbeing Budget (2019, 2020, 2021...) is the most extensively documented attempt to embed wellbeing economics into national governance, and its experience reveals both the potential and the limits of this kind of civilizational revision.

The intellectual architecture is the Treasury's Living Standards Framework (LSF), which identifies four domains of capital (financial and physical, human, social, and natural) and eleven dimensions of current wellbeing (subjective wellbeing, health, education and skills, work and time, material living standards, community and civil society, cultural identity, safety and security, civic engagement, environment, and leisure and play). Government spending decisions are expected to demonstrate how they contribute to these wellbeing dimensions, not merely to economic output.

The 2019 budget was the first operationalization. The government identified five wellbeing priorities: mental health, child wellbeing, Maori and Pasifika wellbeing, a productive nation, and the transition to a low-carbon economy. Funding bids from government agencies were assessed against these priorities and against LSF criteria. The result was a significant reallocation of resources relative to what a pure GDP-optimization framework would have produced: NZD 1.9 billion for mental health services, substantial investment in child poverty reduction, and allocations for housing, disability support, and family violence prevention.

The subsequent years have been more politically complicated. The COVID-19 pandemic dominated fiscal policy in 2020-21, and the wellbeing framework had to be applied to a crisis context for which it had not been designed. Political pressures and electoral considerations created tensions between wellbeing criteria and conventional fiscal prudence. Critics from the right argued that the wellbeing framework was insufficiently rigorous and that GDP growth was being sacrificed for unmeasurable goods; critics from the left argued that the framework was insufficiently transformative and that existing power structures remained intact beneath the wellbeing rhetoric.

The New Zealand experiment demonstrates that wellbeing accounting is technically feasible and politically viable in a stable, small, wealthy democracy with strong institutions. It is less clear how the framework would perform in a larger, more polarized, less institutionally stable context — which is to say, in most of the world.

The most consequential effect of revising economic metrics is not intellectual but behavioral: different measures focus attention differently, and where attention goes, resources follow.

When governments report GDP growth as their primary success metric, ministers and bureaucrats orient their work around activities that contribute to GDP growth. Investments in education, infrastructure, and research and development are justified in terms of their contribution to growth. Environmental regulations are evaluated in terms of their impact on growth. Social programs are designed with labor force participation as a key metric because labor force participation drives growth.

When governments report wellbeing metrics as primary, the orientation shifts. A Scottish government department reporting on its contribution to wellbeing outcomes will design its programs differently than one reporting on its contribution to GDP. The measurement creates accountability, and accountability shapes behavior — not perfectly, not without gaming and resistance, but directionally.

The behavioral change is most visible in investment decisions with long time horizons. GDP accounting, with its quarterly measurement cycle and political pressures for near-term results, systematically underinvests in things whose benefits are distant: early childhood development (which produces returns over decades), preventive health care (which avoids expensive treatment costs 20-40 years later), and natural capital maintenance (which avoids ecosystem collapse costs across generations). Wellbeing frameworks, which are explicitly designed to track long-term outcomes and maintain intergenerational equity, create different incentive structures for these investment decisions.

The carbon accounting revision is perhaps the most consequential example. When carbon emissions are included in national accounts and governments are held accountable for their contribution to atmospheric carbon, the cost-benefit analysis of fossil fuel subsidies changes dramatically. A government that must account for the long-term wellbeing cost of carbon emissions can no longer treat fossil fuel subsidies as economically rational simply because they support near-term GDP growth.

Why, given the intellectual case for wellbeing-based accounting, has it not replaced GDP? The answer is a case study in how entrenched metrics maintain themselves.

First, vested interests: GDP growth is the primary metric against which the financial sector, the export sector, and large corporations are measured. These sectors have significant political influence and benefit from a governance framework that treats their outputs as the primary measure of national success.

Second, path dependence: international comparison, investment decisions, aid flows, debt sustainability assessments, and trade frameworks are all built around GDP. Shifting the primary metric requires changing not just one country's accounting but the whole international architecture — a coordination problem of immense difficulty.

Third, political communication: GDP provides a single, widely understood number that can serve as a political scoreboard. Wellbeing frameworks are necessarily multidimensional and therefore more complex to communicate. Politicians face incentives to use whichever metric gives the most favorable picture, which means GDP is used when growing and critiqued as inadequate when shrinking — an inconsistency that undermines the credibility of both metric and critic.

Fourth, the ideology of growth: economic growth has become quasi-sacral in the political cultures of most countries. Questioning it feels dangerous — like questioning whether prosperity is good. But GDP growth and human prosperity are distinct, and civilizations that mistake the former for the latter will continue making choices that sacrifice the latter for the former.

The revision of economic metrics is not merely a technical improvement in measurement methodology. It is a revision of what civilization is for.

If the purpose of civilization is to maximize production, then GDP is an appropriate metric. If the purpose of civilization is to enable human flourishing — health, connection, purpose, security, beauty, meaning — then GDP is an inadequate and sometimes perverse metric, and the civilization that optimizes for it will systematically neglect the things that matter most.

This is not a new observation. It has been made repeatedly since the development of GDP. The fact that it has not produced a metric revision commensurate with the intellectual case for one is a measure of the power of entrenched measurement systems. Changing what you measure changes what you value, and what you value determines what you build. That is precisely why the people and institutions that benefit from the current arrangement resist the revision of the metric so tenaciously.

The civilizations that manage the 21st century most successfully will be those that develop the institutional capacity to measure what matters and then actually govern by those measures — even when doing so produces short-term GDP costs. New Zealand, Scotland, and the other members of the WEGo partnership are running the experiment. The results, over the coming decades, will determine how many others follow.
