Central Economic Mathematical Institute, Research institute of the Russian Academy of Sciences in Moscow, Russia

The Central Economic Mathematical Institute is a research facility of the Russian Academy of Sciences in Moscow dedicated to developing economic theories through mathematical modeling and quantitative analysis. Located on Nakhimovsky Prospect, it operates specialized research departments focused on economic theory and econometrics.

The institute was created in 1963 as part of the Academy of Sciences of the USSR, replacing the Laboratory of Economics and Mathematical Methods that Vasily Sergeevich Nemchinov had founded in 1958. Its first director, Nikolay Fedorenko, led it until 1985, when Valery Makarov took over; Albert Bakhtizin has headed it since 2017. Branches opened in Tallinn in 1964 and Leningrad in 1966.

The institute is known locally as the "house with the ear", after the square slab above its entrance holding a mosaic high relief of a Möbius strip. Artists E. Zharenova and V. Vasiltsov made the composition in 1976; the architects were Leonid Pavlov, I. Yadrov and G. Kolycheva.

The institute operates several active research departments with different specializations that may offer insight into ongoing scientific work for visitors. Keep in mind it is an academic facility where access may require prior arrangements or scheduling.

In the late 1980s CEMI built much of SUEARN, the Soviet computer network known worldwide as BITNET. It was later merged with the emerging Internet and helped popularize the network among Russians, contributing to the formation of the Runet.
