The Third Circuit: The Soviet Shadow Economy as a Transfer Mechanism between Planned and Consumer Money, 1953–1991

The paper treats the shadow economy of the late USSR as a stable subsystem of reproduction rather than as a collection of legal offences. Its point of origin was the seam between the two circuits into which Soviet monetary circulation was divided. Because the non-cash planned circuit and the cash consumer circuit were insulated from one another while prices were set administratively, a gap opened in which the posted price diverged from the market-clearing price and the right to dispose of a good diverged from ownership of it. Capturing that gap is what shadow activity consisted of, whatever legal form it took. The paper states this formally. A participation condition for an official shows that deterrence is the product of the probability of detection and the severity of the penalty, so that patronage inside the apparatus was worth more than any saving on bribes, and a companion model of riskless arbitrage on scheduled price revisions is calibrated on the criminal case of V. I. Kantor, manager of the Sokolniki department store in Moscow, investigated from 1984 and sentenced in 1989. The calibration yields a return of 14 to 17% a year at zero risk against the 2 to 3% available on the only lawful alternative. Four segments are then examined on their own material: the rationing of scarce goods in state retail trade, the theft and resale of motor fuel in road transport, household plots together with the collective farm market, and underground manufacturing and informal services. Estimates of the phenomenon’s size, which range from 4 to 45% of social product, are brought into one table and their divergence traced to differences of definition rather than of data quality; the eightfold spread across union republics is explained through the same model. The central claim is then tested against the monetary series of the USSR State Bank. Household cash holdings measured in months of retail turnover rose from 1.66 in 1970 to 2.48 in 1985 and 3.29 in 1990, and the average time for a rouble to return to bank tills lengthened from 52 to 104 days, both indicating that a growing share of the currency circulated outside state trade. After the barrier was removed by statute in 1988 the gentle drift turns into a break: cash issue multiplied more than sevenfold in four years while retail turnover grew by two fifths. The shadow economy thus did not destroy the monetary system, but it had built the channel that the legislation of 1988 legalised.
