Fariborz Raisdana, a prominent Iranian Marxist economist who criticized government-subsidy cuts1 by Mahmoud Ahmadinejad's administration and spent one year behind bars, specifies that 90 percent of imports, 25 percent of exports, and 48 percent of investments are by the private sector.  Moreover, 95 percent of the country's housing has been built by the private sector.  Nineteen percent of the country's agriculture belongs to the private sector, too.
