Economy of North Korea
Estimating gross national product in North Korea is a difficult task because of a dearth of economic data and the problem of choosing an appropriate rate of exchange for the North Korean won, the nonconvertible North Korean currency. The South Korean government's estimate placed North Korea's GNP in 1991 at US$22.9 billion, or US$1,038 per capita. In contrast, South Korea posted US$237.9 billion of GNP and a per capita income of US$5,569 in 1991. North Korea's GNP in 1991 showed a 5.2% decline from 1989, and preliminary indications were that the decline would continue. South Korea's GNP, by contrast, expanded by 9.3% and 8.4%, respectively, in 1990 and 1991.
North Korea
The economy is heavily nationalized. Food and housing are extensively subsidized by the state; education and healthcare are free; and the payment of taxes was officially abolished in 1974. A variety of goods are available in department stores and supermarkets in Pyongyang, though most of the population relies on small-scale "jangmadang" markets. In 2009, the government attempted to stem the expanding free market by banning jangmadang and the use of foreign currency, heavily devaluing the won and restricting the convertibility of savings in the old currency, but the resulting inflation spike and rare public protests caused a reversal of these policies. Private trade is dominated by women because most men are required to be present at their workplace, even though many state-owned enterprises are non-operational.
