Cost and Prices in Moscow
Some prices are considerably higher for the foreign visitor than for locals. A cost of living survey by Mercer Human Resource Consulting puts Moscow in second place after Tokyo, making it the most expensive city in Europe.
For natives, small apartments bought or given by the state in the Soviet era, coupled with extremely low utility costs and easily avoidable income tax serve to lower the cost of living greatly.
A look at transport prices offers a good illustration. A taxi from Sheremetyevo International Airport will cost the non-Russian speaking traveler upwards of $60; the Russian speaking foreigner will be charged $30-$40.
The native Moscow dweller will negotiate the price to $15-20 or will avoid the taxi rank altogether and take a shared taxi to the nearest metro station for about 1 dollar.
