Aleh Tsvynski and Sergei Guriev wrote a brief article on Russia's state of the economy and political stability. Here's a slice of the article:
"The other major barrier to growth is corruption. In another World Bank-EBRD survey, 40% of firms in Russia reported making frequent unofficial payments, and roughly the same percentage indicated that corruption is a serious problem in doing business. Unlike in other emerging markets, corruption has not declined with economic growth; it remains as high as in countries with one-quarter the per capita income of Russia."
