The formula treats three conditions—heavy debt, a large wealth gap, and an economic downturn—as interacting sources of instability. A downturn reduces available resources while debt obligations remain, forcing a dispute over how to divide a smaller economic pie. A sovereign currency issuer may finance deficits by creating money, but a state or city must usually raise taxes, cut services, or seek outside support. Higher taxes can drive affluent residents and businesses away, while service cuts hurt poorer residents and reduce local attractiveness. The resulting loss of tax revenue can trigger further cuts and departures, converting a temporary fiscal shock into a self-perpetuating decline.

Core principles
- 01High debt limits painless policy choices
- 02Large wealth gaps intensify distributional conflict
- 03Economic downturns expose weaknesses that growth can conceal
- 04Currency issuers and subnational governments face different constraints
- 05Resident and tax-base departures can make decline self-reinforcing
How to run it
- 1
Measure accumulated obligations
Compile debt, pension liabilities, and other fixed commitments relative to recurring revenue. Determine how much flexibility remains before essential spending is affected.
Pro tip Include obligations that are politically difficult to reduce, not just formally issued debt.
Watch out Headline debt alone may understate the true burden.
- 2
Map the distribution gap
Assess how income, wealth, services, and political influence are distributed. Identify which groups would bear tax increases, spending cuts, inflation, or unemployment.
Pro tip Analyze different economic groups as distinct economies rather than relying only on averages.
Watch out Aggregate prosperity can conceal severe local deprivation.
- 3
Apply a downturn stress test
Model what happens when revenue and employment fall while debt-service and social needs rise. Identify the point at which distributional disagreements become acute.
Pro tip Use multiple downturn severities rather than one forecast.
Watch out A shock can accelerate dynamics that already existed during expansion.
- 4
Identify the financing constraint
Determine whether the government can create money or must balance through taxation, spending cuts, borrowing, or external aid. This constraint defines the available response set.
Pro tip Separate sovereign currency issuers from states, cities, and currency users.
Watch out Assuming every government can monetize deficits produces misleading conclusions.
- 5
Model the feedback loop
Estimate whether taxes, service reductions, or political antagonism will cause mobile residents and businesses to leave. Feed the resulting tax-base loss back into the fiscal model.
Pro tip Track both financial departures and the loss of skilled people.
Watch out Linear forecasts miss self-reinforcing decline.
In the wild
A state with large pension obligations and a pronounced wealth gap loses revenue during a recession. Because it cannot print money, officials consider higher taxes and service cuts. High-income residents begin relocating, taking taxable income with them, while reduced services make the state less attractive to families and employers. The analyst models these departures as a feedback loop rather than a one-time revenue loss.
→ Leaders see how apparently balanced measures could deepen the fiscal problem and can prioritize reforms that preserve the tax base and essential services.
Common mistakes
Analyzing each variable in isolation
Debt, inequality, and downturns become most dangerous through their interaction rather than their independent levels.
Ignoring monetary sovereignty
A federal currency issuer and a state government do not possess the same options for financing deficits.
Treating migration as a static assumption
Tax increases, deteriorating services, and political conflict can change where people and businesses choose to locate.
Is it for you?
Best for
It is best for evaluating countries, states, cities, or institutions exposed to debt, inequality, and cyclical stress.
Not ideal for
It is not ideal for jurisdictions with strong balance sheets, low inequality, and little sensitivity to resident migration.
