The model begins with three interacting surpluses: labor, productive capacity, and capital. Billions of workers entering global markets expand labor supply, while industrial investment increases the volume of goods that can be produced. Because workers in emerging economies do not immediately consume as much as they produce, demand fails to absorb that output. Their savings and trade surpluses flow into developed-country sovereign bonds, depressing interest rates and encouraging leverage, asset inflation, and additional capacity. When debt-financed demand retreats, excess capacity remains and wages stay weak. The resulting mechanism produces low inflation, sluggish investment, and persistent demand shortfalls even when central banks supply abundant liquidity. Analysis therefore follows money, wages, capacity utilization, and debt-supported consumption rather than assuming an ordinary cyclical rebound.

Core principles
- 01Evaluate labor, productive capacity, and capital together.
- 02Trace excess supply back to structural rather than merely cyclical forces.
- 03Follow capital flows to understand interest rates and asset prices.
- 04Separate genuine demand from demand temporarily financed by debt.
- 05Treat wage growth as a prerequisite for sustained inflation.
How to run it
- 1
Map the labor supply
Estimate how globalization, labor-force participation, immigration, and technology affect the number of workers available relative to employment demand.
Pro tip Include technology-driven reductions in required headcount rather than relying on demographics alone.
Watch out Do not infer labor scarcity merely from an aging population.
- 2
Assess productive capacity
Compare factories, infrastructure, real estate, and other capacity with demand that can be sustained without continually expanding debt.
Pro tip Look for idle facilities, falling producer prices, and exports sold into already-saturated markets.
Watch out Capacity built for anticipated growth can become persistent oversupply.
- 3
Follow surplus capital
Trace savings and trade surpluses into bonds, cash, property, and other assets. Determine whether these flows suppress yields or inflate valuations.
Pro tip Treat unusually strong demand for sovereign debt as evidence of capital seeking safety rather than productive investment.
Watch out Low yields can make uneconomic projects appear attractive.
- 4
Separate organic from borrowed demand
Identify consumption and investment that arose from income growth versus credit expansion. Remove the debt-supported component when estimating durable demand.
Pro tip Compare debt growth with wage and consumption growth over the same period.
Watch out Debt-financed demand can conceal oversupply until credit contracts.
- 5
Test wages and inflation
Check whether labor compensation is rising broadly enough to support sustained price increases. Without wage movement, isolated price shocks are less likely to become durable inflation.
Pro tip Examine wage growth across income groups rather than relying only on aggregate averages.
Watch out A larger monetary base alone does not prove inflation is imminent.
- 6
Classify the condition
Decide whether observed weakness is a temporary cyclical contraction or a structural oversupply problem requiring demand-side adjustment.
Pro tip Use multi-year trends in debt, participation, wages, capacity utilization, and capital flows.
Watch out Applying a standard cyclical recovery forecast to a secular imbalance can produce persistent errors.
In the wild
An analyst observes a larger central-bank balance sheet, rising stock prices, weak business investment, stagnant median wages, and heavy foreign demand for government bonds. Applying the model, the analyst concludes that surplus capital is lifting asset prices while excess labor and capacity suppress wages and consumer prices. The analyst therefore avoids forecasting immediate broad inflation solely from monetary expansion.
→ The forecast focuses on continued low inflation and asset-price sensitivity rather than a conventional demand boom.
Common mistakes
Calling every downturn cyclical
A normal business-cycle model can miss decade-long debt reduction, globalization, and technological displacement. Test explicitly for structural persistence.
Ignoring debt-supported demand
Past sales or capacity utilization may have depended on unsustainable credit creation. Treating that demand as permanent exaggerates future needs.
Forecasting inflation from money alone
Liquidity can remain in sovereign debt and financial assets rather than circulating through wages and consumption. Examine transmission before predicting inflation.
Is it for you?
Best for
It is best for investors, economists, and policymakers assessing economies affected by globalization, automation, excess capacity, and debt overhangs.
Not ideal for
It is not ideal for short-term market timing or economies experiencing genuine scarcity and broad wage-driven inflation.
From the transcript
“at some point you have to follow the money”
“Unless you can move wages, you cannot create inflation.”
“What you're effectively doing is you're trying to solve a demand side problem with supply side remedies.”
