Output in Serbia and Montenegro dropped by half in 1992-93. Like the other former Yugoslav republics, it had depended on its sister republics for large amounts of energy and manufactures. Wide differences in climate, mineral resources, and levels of technology among the republics accentuated this interdependence, as did the communist practice of concentrating much industrial output in a small number of giant plants. The breakup of many of the trade links, the sharp drop in output as industrial plants lost suppliers and markets, and the destruction of physical assets in the fighting all have contributed to the economic difficulties of the republics. One singular factor in the economic situation of Serbia is the continuation in office of a communist government that is primarily interested in political and military mastery, not economic reform.
Reliable statistics continue to be hard to come by, and the GDP estimate is extremely rough.
The economic boom anticipated by the government after the suspension of UN sanctions in December 1995 has failed to materialize. Until the government cooperates on such matters as human rights and war criminals, it will lack full support from international financial institutions.
