Employment indicators describe how people are allocated across sectors, but they do not explain why productivity gaps persist. To follow that question further, we must also examine the financial structure of the economy.
In particular, we must consider how bank balance sheets and regulatory choices influence the allocation of credit.The term zombie bank is often used in public debate, sometimes with moral judgment.
Analytically, however, it describes a specific combination of financial conditions and regulatory choices.
Understanding that mechanism is essential before evaluating its consequences.
1. Economic Insolvency
A bank becomes economically insolvent when the market value of its assets falls below the value of its liabilities.
Assets (market value) < Liabilities
Equity < 0
If such losses were fully recognized, the institution would normally require recapitalization, restructuring, or resolution.
In practice, however, asset values may be uncertain and recognition of losses can be delayed.
2. Financial Forbearance
Financial forbearance occurs when regulators allow an undercapitalized or insolvent bank to continue operating without immediate resolution.
- delayed recognition of losses
- flexible asset classification
- postponement of capital requirement enforcement
- provision of liquidity support
Such measures are often justified as crisis management.
Authorities may seek to prevent panic, credit collapse, or systemic contagion.
3. Evergreening
When losses remain unrecognized, banks may continue lending to weak borrowers rather than forcing restructuring.
This behavior is commonly described as evergreening.
Weak Bank → Extends Credit to Weak Firm
Weak Firm → Avoids Bankruptcy
Evergreening postpones loss realization, but it may also distort the allocation of capital.
4. The Capital Allocation Channel
The broader economic consequences emerge through capital allocation.
If impaired banks continue lending to low-productivity firms while restricting credit to stronger entrants, the reallocation of resources slows.
- aggregate productivity growth weakens
- sectoral dispersion can persist
- structural adjustment slows
Financial stability may be preserved in the short run.
Unemployment may not surge immediately.
Yet long-run dynamism can weaken as capital remains tied to less productive uses.
5. Stability and Dynamism
The central tension becomes clear.
Immediate resolution may intensify crisis conditions in the short run.
Persistent forbearance may delay restructuring and weaken productivity growth in the long run.
The analytical task is therefore not simply to praise or condemn forbearance.
It is to ask under what conditions financial support stabilizes the system and under what conditions it preserves structural inefficiency.
Seen from this perspective, zombie banking is not only a financial phenomenon.
It is also a structural productivity issue.
If weak banks continue supporting weak firms, capital reallocation slows, diffusion weakens, and productivity gaps may persist across sectors and firms.
This discussion therefore connects financial allocation mechanisms to the broader structural patterns examined in the EPISODE series.

Financial allocation, however, is only one part of the structural picture.
Even when capital is misallocated, the persistence of productivity gaps also depends on whether workers can move easily toward more productive activities.
