"It lets you both model inflation and attribute it sectorally—to wages, productivity, domestic debt saturation, and the external / tradables channel—within a consistent stock–flow, income‑distribution perspective."
Equation (K3) is the Kalecki distributional inflation equation: inflation depends on wage growth, productivity growth, and changes in the core profit share, scaled by the wage share 1−θ
Step 3 – Young’s claim‑dilution ratio
"meaning: excess credit over productive equity tends to raise the core profit share."
This is the closed‑economy Kalecki–Young model.
Step 4 – Open‑economy extension: adding the tradables channel (KYCD‑T)
Step 5 – Sectoral decomposition: KYSID
This is the Kalecki–Young Sectoral Inflation Decomposition (KYSID): an inflation framework grounded in Kalecki’s pricing and distribution, enriched by Young’s balance‑sheet concept of claim dilution and extended to an open economy.

Why δ is “excess claim creation”
...."is the net increase in nominal claims on future domestic income not matched by new productive backing."

“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Once capital is non-fungible, such exclusion is no longer valid, and New Keynesian models lose closure without explicit balance-sheet dynamics.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."
