"one factor explaining the inchoate performance of the Iranian economy since the revolution." Other factors include the long war with Iraq, the cost of which led to government debt and inflation, eroding personal incomes, and unprecedented unemployment, ideological disagreement over the economy, and "international pressure and isolation" such as US sanctions following the hostage crisis. Due to the Iran–Iraq War, poverty is said to have risen by nearly 45% during the first 6 years of Khomeini's rule. Emigration from Iran also developed, reportedly for the first time in the country's history. Since the revolution and war with Iraq, an estimated "two to four million entrepreneurs, professionals, technicians, and skilled craftspeople (and their capital)" have emigrated to other countries.

Acting on the orders of Khomeini, the Islamic Republic responded by shooting demonstrators, including children.
