Russian Empire Soviet Union Beginning in 1928, the course of the Soviet Union's economy was guided by a series of five-year plans. By the 1950s, the Soviet Union had rapidly evolved from a mainly agrarian society into a major industrial power. By the 1970s the Soviet Union was in an Era of Stagnation. The complex demands of the modern economy and inflexible administration overwhelmed and constrained the central planners. The volume of decisions facing planners in Moscow became overwhelming. The cumbersome procedures for bureaucratic administration foreclosed the free communication and flexible response required at the enterprise level for dealing with worker alienation, innovation, customers, and suppliers. From 1975 to 1985, corruption and data fiddling became common practice among bureaucracy to report satisfied targets and quotas thus entrenching the crisis. Starting in 1986, Mikhail Gorbachev attempted to address economic problems by moving towards a market-oriented socialist economy. Gorbachev's policies of Perestroika failed to rejuvenate the Soviet economy; instead, a process of political and economic disintegration culminated in the breakup of the Soviet Union in 1991. Transition to market economy (1991–98) Following the collapse of the Soviet Union, Russia underwent a radical transformation, moving from a centrally planned economy to a globally integrated market economy. Corrupt and haphazard privatization processes turned over major state-owned firms to politically connected "oligarchs", which has left equity ownership highly concentrated. Yeltsin's program of radical, market-oriented reform came to be known as a "shock therapy". It was based on the policies associated with the Washington Consensus, recommendations of the IMF and a group of top American economists, including Larry Summers who in 1994 urged for "the three '-ations'—privatization, stabilization, and liberalization" to be "completed as soon as possible." With deep corruption afflicting the process, the result was disastrous, with real GDP falling by more than 40% by 1999, hyperinflation which wiped out personal savings, crime and destitution spreading rapidly. The jump in prices from shock therapy wiped out the modest savings accumulated by Russians under socialism and resulted in a regressive redistribution of wealth in favour of elites who owned non-monetary assets. Shock therapy was accompanied by a drop in the standard of living, including surging economic inequality and poverty, along with increased excess mortality and a decline in life expectancy. Russia suffered the largest peacetime rise
