The link between economic growth and human wellbeing seems obvious. As measured by gross domestic product, economic growth is widely viewed as the ultimate development objective. But it is time to rethink this approach.
In fact, there is a rising disconnect between countries’ per capita GDP and their citizens’ wellbeing, as rapid output growth exacerbates health challenges and erodes environmental conditions. Given this, people increasingly value nonmaterial wealth just as highly as monetary wealth, if not more.
But persuading policymakers and politicians of GDP’s limitations is no easy feat. After all, it is far simpler to defend a well-understood, long-accepted framework than it is to champion a new worldview. To be sure, GDP provides valuable information about a country’s production, expenditure, and income streams, as well as the flow of goods across borders. Moreover, it has provided crucial guidance to countries, helping them to track economic gains that have improved citizens’ quality of life considerably — in many cases lifting them out of destitution.
But GDP fails to account for changes in a country’s stock of assets, making it difficult for policymakers to balance economic, social, and environmental concerns. Without better measures of wellbeing — including health, education, and the state of the natural environment — policymakers cannot gain the insights that they need to ensure the long-term health of the economy and the individuals who comprise it.
This imperative underpins the concept of “sustainable development,” which has gradually gained acceptance since its introduction in the mid-1980s. But even as countries have recognized the need for a more comprehensive understanding of development, they have largely retained GDP growth as their central objective. This has to change.
Even U.S.-based Nobel laureate Simon Kuznets, the Depression-era father of GDP, said in 1934 that “the welfare of a nation can scarcely be inferred from a measure of national income.”
The good news is that a robust and effective framework for measuring sustainability already exists. Developed by a group of leading economists, including the Nobel laureate Kenneth Arrow and Partha Dasgupta of the University of Cambridge, it assesses an economy’s income flows in the context of its stocks of assets, including human and natural capital. In other words, it accounts for the economy’s productive base, rather than just its monetary wealth.
Based on this framework, United Nations University and the U.N. Environment Program unveiled the Inclusive Wealth Report (IWR) at the 2012 Earth Summit in Rio de Janeiro. By providing a long-term comparison between GDP and “inclusive wealth” for 20 countries, the report aimed to motivate policymakers to take a more comprehensive, longer-term view of their economies’ development.
This November, a second IWR will be released, with many more countries represented and a stronger focus on human capital in national-account indicators. To this end, collaborating experts will convene in Malaysia this month for a series of meetings, culminating in a public symposium titled “Beyond Gross Domestic Product — Transitioning into Sustainability.”
Transforming the world’s understanding of economic development requires a dynamic approach. Experts in various fields — including economics, sociology, psychology and the natural sciences — must work together to develop an integrated suite of indicators that provides a comprehensive picture of humanity’s productive base, on which people’s ability to pursue their interpretation of success depends.
While final decisions should rest with policymakers and citizens, the process must be guided by the best available science, uncompromised by political demands or vested interests.
Moreover, one fundamental truth must be recognized: The planet cannot accommodate high-income status for all 7 billion of its inhabitants. For every country to attain per capita GDP of $13,000 (which, according to the World Bank, delineates high-income status), global GDP would need to rise from roughly $72 trillion today to $91 trillion. If, however, we already use the equivalent of 1.5 earths to provide the resources we consume and to absorb our waste, the planet can sustainably support a GDP of only $48 trillion to $50 trillion.
And if the planet already exceeds its sustainable carrying capacity, we should be reducing our demands on it — not adding new ones.
Simply put, we can no longer depend on GDP growth, and the limitless wealth accumulation that it implies, to solve our social and economic problems.
The world must align its value systems with this reality. We must learn to do more with less, decouple economic growth from resource consumption, and nurture the social and spiritual aspects of our existence.
This shift will be impossible without fundamental changes in education systems, political structures and institutions. It is a tall order, but our future depends on fulfilling it.
