Policy Regimes Are Balance-Sheet States, Not Discretionary Switches
“Using a Markov-switching reaction function and logit bridge, we show that the probability of an ‘active’ Fed regime rises systematically with total-debt-to-GDP (Ω). Policy regime is not independent; it’s a balance-sheet state.”
Logic (what we tested)
Main specification (Logit on Active indicator)
The Markov model’s “regime switches” are not free policy choices; they are balance-sheet phases. Rising Ω (claim load) statistically raises the probability we observe the active reaction-function state.
Scope: This establishes state-contingency, not a one-variable monocause. DSR and profitability also matter, consistent with a cash-flow feasibility view of policy.
Table X. Logit Regression — Determinants of “Active” Policy Regime Probability
Across specifications, the probability increases systematically with Ω, implying that policy stance is endogenously determined by debt saturation rather than exogenously chosen.

“NK models require fungible capital to avoid balance sheets — "
Non-fungible capital isn’t a hypothesis that needs testing — it’s the real-world condition.
Fungible capital is the modelling assumption, and once you drop it, balance sheets become unavoidable...
.. and the NK equilibrium story disappears.
Once capital is non-fungible, such exclusion is no longer valid, and New Keynesian models lose closure without explicit balance-sheet dynamics.
When demand shifts or prices change, firms can’t just move their capital to a better use. They’re left with assets that may no longer earn enough revenue — but the debts used to build those assets don’t disappear.
From Credit Creation to Claim Enforcement: Debt Service, Labour Share, and Balance-Sheet Constraints
"Macroeconomic models that omit leverage and debt service as state variables are therefore empirically incomplete for the purposes of analysing modern inflation and distribution dynamics in high-debt economies."
Services Inflation Dynamics, Housing Pass-Through, and the Misinterpretation of Wage Inflation
"In sum, services inflation in the United States is best understood as a housing-anchored, lag-driven process in which wages play an adaptive rather than causal role."
