in his office. In 1987 he was made a corresponding member of the Academy of Sciences; and in 1994, a full member. In 1990 -1991, he served on the Central Committee of the Communist Party of the Soviet Union. In the 1980s, the Five Year Plans were set in 20-year outlooks on economic, scientific and technical development which were primarily the work of Yaremenko. His most fundamental contribution to economics was the working out of the theory of the multilevel economy. In this theory, different levels of the economy have access to resources of different quality. There had been various economic theories of socialism. Yaremenko's work, however, was unique in describing theoretically and analytically how it actually worked in the Soviet Union. Yaremenko was one of the principal economic advisers to Mikhail Gorbachev, last president of the USSR. Yaremenko warned that simply discontinuing central planning and opening the country to foreign trade would lead to collapse of consumer goods sectors which could not compete with imports. Rather, the system of priorities should first be used to transform the economy's structure to something approximating that of market economy. This advice was not heeded, and the consequences were much as he had anticipated. In the 1990s, he was sharply critical of the policies adopted by the Russian government. He was not at all opposed to an orderly transition to a market economy but felt that the “shock therapy” approach was needlessly costly. Throughout his professional career, he was much concerned with sources of information on the economy. On weekends, he often went to the Lenin library to see what the technical journals had to offer about the economic situation in various industries. In the 1990s, he engaged a sociologist, S. A. Belonovskiï, to interview plant managers around the country. In 1993 and again in 1995, Belonovskiï interviewed Yaremenko. After his death, these interviews were edited by Belonovskiï and G. A. Yaremenko into a book, Economic Conversations, which appeared in 1998. They afford a unique and altogether remarkable commentary on the dramatic events in the Russian economy during the first half of the 1990s. In October 2015, the year of the 80th anniversary of Yaremenko's birth, the Economic Forecasting Institute of the Academy of Sciences held a three-day conference to honor his memory. The first day was devoted to analysis of the current economic situation; the second, to economic modeling; and the third,
