Theoretical catalyst of the 1965 Soviet economic reform

'What is profitable for society should be profitable for every enterprise' — the central proposition of his 1962 Pravda article

Soviet economist. His article 'Plan, Profit, Premium' in Pravda (September 1962) triggered the all-union economic discussion that led to the 1965 Kosygin reform, the most significant Soviet attempt to introduce profitability and enterprise autonomy into the planned economy. He argued that what is profitable for society must also be profitable for each enterprise. In the 1920s he created the USSR's first machine-accounting station. Arrested on fabricated charges in 1938, he was rehabilitated in late 1939. His wife Regina Horowitz was the sister of pianist Vladimir Horowitz.

Founder of Soviet economic sociology; her 1983 report lit the intellectual fuse of perestroika

She was president of the Soviet Sociological Association, founding director of VTsIOM, and a People's Deputy who worked with Sakharov and Yeltsin.

The historian who called the conservative majority 'aggressively obedient'
