According to economist Robert Solow, the issue with metrics like GDP isn't mismeasurement, but a deliberate choice to exclude factors like natural resource depletion. The system is flawed because we have decided not to measure certain things, which creates a distorted view of economic health.

While "growth" is viewed positively in economics, Raworth reframes it using a medical analogy. In any complex living system, from the human body to the planet, something that tries to grow forever is a cancer. This highlights the destructive nature of pursuing infinite economic expansion on a finite planet.
Traditional metrics like GDP fail to capture the value of intangibles from the digital economy. Profit margins, which reflect real-world productivity gains from technology, provide a more accurate and immediate measure of its true economic impact.
Nobel laureate Robert Solow critiques modern macroeconomic models (DSGE) for being overly abstract and failing to represent an economy with diverse actors and conflicting interests. By modeling a single representative agent, he argues, the field has detached itself from solving real-world economic problems.
Post-WWII, economists pursued mathematical rigor by modeling human behavior as perfectly rational (i.e., 'maximizing'). This was a convenient simplification for building models, not an accurate depiction of how people actually make decisions, which are often messy and imperfect.
Traditional GDP is a flawed metric that incentivizes harmful activities (like cancer). A better dashboard for societal health would measure the multiplicative balance of Material capital, Intelligence, Network effects, and Diversity (resilience). A zero in any of these categories leads to systemic collapse.
A government can artificially inflate its jobs numbers and GDP by going on a hiring spree for bureaucratic roles. This growth is illusory, or "phantom," as it's funded by printing money and doesn't contribute to the productive economy. It creates positive short-term metrics but fosters long-term inefficiency.
The dominant economic model pursues endless growth, often at a human or planetary cost. Donut Economics reframes the goal entirely: create economies that allow humanity to thrive by meeting essential needs while respecting planetary boundaries, irrespective of continuous GDP growth.
Headline GDP figures can be misleading in an environment of high immigration and inflation. Metrics like per-capita energy consumption or the number of labor hours needed to afford goods provide a more accurate picture of individual well-being, revealing that many feel poorer despite positive official growth numbers.
The official poverty line is calculated as 3x the cost of food, a metric from the 1960s when food was a third of a household budget. Today, food is only 13% of spending while housing and healthcare have soared, making the official metric a poor reflection of modern economic hardship.
Including government employment in GDP calculations is a form of double-counting tax revenue that masks the true health of the private sector. A major reduction in federal workers would reveal a startlingly low real growth rate, exposing decades of underlying economic stagnation.
