Shortage economics & the soft budget constraint
Editorial · Kornai / soft budget constraints / queuing & hoarding / the quantity drive
Kornai's account of how planned economies actually behaved. Chronic shortage was not bad management or sabotage — it was a systemic property produced by soft budget constraints and the drive for quantity.
The claim
János Kornai's achievement was to explain why the shortages that defined daily life across the Eastern Bloc were not bad luck, bad management, or sabotage, but a systemic property of the planned economy — as predictable as inflation is in an overheated market economy.
The core mechanism is the soft budget constraint. In a market economy a firm faces a hard budget: spend more than you earn for long enough and you fail. In a planned economy the state stands behind its firms — through subsidies, soft credit, tax forgiveness and bailouts — so the link between a firm's spending and its earnings goes slack (Kornai, "The Soft Budget Constraint," Kyklos, 1986).
- Softness kills the penalty for waste. A firm that will always be rescued has no reason to economise and no fear of failure to discipline it.
- So demand for inputs becomes nearly unlimited — Kornai's "investment hunger" and "quantity drive." Every firm hoards materials and labour against the next plan target, producing a suction economy of chronic shortage rather than the pressure economy of a demand-constrained market.
- Ordinary people adapt rationally. Queuing, hoarding, bribery, informal markets and "forced substitution" — buying what's available, not what's wanted — are the sane responses to permanent scarcity.
- Quantity targets corrode quality. Output measured in tons yields needlessly heavy goods; output measured in units yields flimsy ones. The plan can specify how much, but not how good.
- Shortage and waste coexist. Unwanted goods pile up unsold while needed goods vanish — a pattern no simple "they just underproduced" story can explain.
The scholarly debate
How much of this is intrinsic to public ownership, and how much is fixable by institutional design? Kornai, with Maskin and Roland, later argued the soft budget constraint is not unique to socialism — it appears wherever a paternalist backer (a government, a too-big-to-fail bank) will cover losses ("Understanding the Soft Budget Constraint," 2003). The live question: could socially-owned firms ever face a genuinely hard budget — real bankruptcy, no rescue — without, in effect, recreating capitalism?
Strongest counterargument
◆ Against this entry’s own thesis
Nove and other market socialists reply that chronic shortage indicts *this* institutional design, not social ownership as such: a "feasible socialism" with autonomous firms, real market prices and permitted bankruptcy could harden budget constraints while keeping the returns to capital socially owned. The softness, they argue, comes from *politics* — the state's unwillingness to let a firm fail and throw people out of work — not from ownership per se. The rejoinder is that the same politics is exactly what social ownership tends to produce: when the owner is the state, letting a state firm die is always a political act, and the budget re-softens.
