Zombie Firm Dynamics in Financial Systems
Summary
Zombie firms are enterprises that persistently generate insufficient earnings to cover their debt servicing costs, yet continue operating through repeated refinancing or policy support. Such firms trap capital and labour in unproductive activities, leading to resource misallocation and depressed aggregate productivity. Their prevalence tends to rise in periods of low interest rates, abundant liquidity and lenient insolvency regimes, which together weaken market selection and encourage the survival of marginal operators. The dynamics of zombification encompass firm entry, prolonged underperformance, potential recovery through restructuring and eventual exit, often influenced by macroeconomic policies and creditor behaviour. Cross-country studies reveal that the scale and persistence of zombie firms vary according to financial sector depth, legal frameworks and the stringency of fiscal or monetary interventions. Understanding these dynamics is critical for policymakers aiming to foster healthy competition, direct capital towards innovative or higher-productivity activities and mitigate systemic risks associated with widespread corporate distress.
