A decrease in oil revenues in 1991 and growing external debt, though, dampened optimism. In March 1989, Khomeini had approved Rafsanjani's 5-year plan for economic development, which allowed Iran to seek foreign loans. But mismanagement and inefficient bureaucracy, as well as political and ideological infighting, have hampered the formulation and execution of coherent economic policies. Today, Iran's economy is a mixture of central planning, state ownership of oil and other large enterprises, village agriculture, and smallscale private trading and service ventures. Former President Khatami followed the market reform plans of his predecessor, President Rafsanjani, and indicated that he would pursue diversification of Iran's oil-reliant economy, although he made little progress toward that goal.

Unemployment was estimated to be 11.2% for 2004. Although Islam guarantees the right to private ownership, banks and some industries--including the petroleum, transportation, utilities, and mining sectors--were nationalized after the revolution. Iran has, however, been pursuing some privatization. The import-dependent industrial sector is further plagued by low labor productivity and shortages of raw materials and spare parts.

Agriculture also has suffered from shortages of capital, raw materials, and equipment, as well as from the war with Iraq; in addition, a major area of dissension within the regime has been how to proceed with land reform.

Increases in the price of oil starting in 2003 have increased state revenue enormously and permitted a much larger degree of spending on social programs than previously anticipated. However, this has not eased economic hardships such as high unemployment and inflation. The proportion of the economy devoted to the development of weapons of mass destruction remains a contentious issue with leading Western nations.
