The cost of subsidising items like food, rents and transport rose from 16.9 billion Ostmarks in 1980 to 49.8 billion by 1989.
By this time, for every 100 Ostmarks spent on food, the state was subsidising it to the tune of 89 Ostmarks.
Economists understood the problem early on: in 1972, the president of the State Bank had worried that this level of subsidy would make the external debt problem worse.
Honecker accused people of sabotage when officials raised the issue with him.
