"The corruption situation is so dramatic that the report authors singled out corruption-related losses of Russian economy. They estimated these losses at about 50% expenses of Russian businesspeople. Some 80% of current assets in the education system are shadowy, that is to say mainly related to the corruption, and this figure reaches 90% in state and municipal services."
I'm guessing they meant 50% of GDP is in black markets, or that 50% of business expenses go to bribing people.
