the remaining output as they saw fit. However, at the same time the state still held control over the means of production for these enterprises, thus limiting their ability to enact full-cost accountability. Enterprises bought input from suppliers at negotiated contract prices. Under the law, enterprises became self-financing; that is, they had to cover expenses (wages, taxes, supplies, and debt service) through revenues. No longer was the government to rescue unprofitable enterprises that could face bankruptcy. Finally, the law shifted control over the enterprise operations from ministries to elected workers' collectives. Gosplan's responsibilities were to supply general guidelines and national investment priorities, not to formulate detailed production plans. The Law on Cooperatives, enacted in May 1988, was perhaps the most radical of the economic reforms during the early part of the Gorbachev era. For the first time since Vladimir Lenin's New Economic Policy was abolished in 1928, the law permitted collective ownership of businesses in the services, manufacturing, and foreign-trade sectors. The law initially imposed high taxes and employment restrictions, but it later revised these to avoid discouraging private-sector activity. Under this provision, cooperative restaurants, shops, and manufacturers became part of the Soviet scene. Gorbachev brought perestroika to the Soviet Union's foreign economic sector with measures that Soviet economists considered bold at that time. His program virtually eliminated the monopoly that the Ministry of Foreign Trade had once held on most trade operations. It permitted the ministries of the various industrial and agricultural branches to conduct foreign trade in sectors under their responsibility, rather than having to operate indirectly through the bureaucracy of trade ministry organizations. In addition, regional and local organizations and individual state enterprises were permitted to conduct foreign trade. This change was an attempt to redress a major imperfection in the Soviet foreign trade regime: the lack of contact between Soviet end users and suppliers and their foreign partners. Alexander Yakovlev was considered to be the intellectual force behind Gorbachev's reform program of glasnost and perestroika. In the summer of 1985, Yakovlev became head of the propaganda department of the CPSU Central Committee. He argued in favor of the reform programs and played a key role in executing those policies. The most significant of Gorbachev's reforms in the foreign economic sector allowed foreigners to invest in the Soviet Union in the form of joint ventures with Soviet ministries, state enterprises, and cooperatives.
