Background | Guyana achieved independence from the UK in 1966 and became a republic in 1970. In 1989 Guyana launched an Economic Recovery Program, which marked a dramatic reversal from a state-controlled, socialist economy towards a more open, free market system. Results through the first decade have proven encouraging. | The UK annexed Southern Rhodesia from the South Africa Company in 1923. A 1961 constitution was formulated that favored whites in power. In 1965 the government unilaterally declared its independence, but the UK did not recognize the act and demanded more complete voting rights for the black African majority in the country (then called Rhodesia). UN sanctions and a guerrilla uprising finally led to free elections in 1979 and independence (as Zimbabwe) in 1980. Robert MUGABE, the nation's first prime minister, has been the country's only ruler (as president since 1987) and has dominated the country's political system since independence. His chaotic land redistribution campaign begun in 2000 caused an exodus of white farmers, crippled the economy, and ushered in widespread shortages of basic commodities. Ignoring international condemnation, MUGABE rigged the 2002 presidential election to ensure his reelection. Opposition and labor groups launched general strikes in 2003 to pressure MUGABE to retire early; security forces continued their brutal repression of regime opponents. |

Economy - overview | Severe drought and political turmoil contributed to Guyana's negative growth of -1.8% for 1998 following six straight years of growth of 5% or better. Growth came back to a positive 1.8% in 1999 and 3% in 2000. Underlying growth factors have included expansion in the key agricultural and mining sectors, a more favorable atmosphere for business initiative, a more realistic exchange rate, a moderate inflation rate, and continued support by international organizations. President JAGDEO, the former finance minister, is taking steps to reform the economy, including drafting an investment code and restructuring the inefficient and unresponsive public sector. Problems include a shortage of skilled labor and a deficient infrastructure. The government must persist in efforts to manage its sizable external debt and attract new investment. | The government of Zimbabwe faces a wide variety of difficult economic problems as it struggles with an unsustainable fiscal deficit, an overvalued exchange rate, soaring inflation, and bare shelves. Its 1998-2002 involvement in the war in the Democratic Republic of the Congo, for example, drained hundreds of millions of dollars from the economy. Badly needed support from the IMF has been suspended because of the country's failure to meet budgetary goals. Inflation rose from an annual rate of 32% in 1998 to 133% at the end of 2004, while the exchange rate fell from 24 Zimbabwean dollars per US dollar to 6,200 in the same time period. The government's land reform program, characterized by chaos and violence, has badly damaged the commercial farming sector, the traditional source of exports and foreign exchange and the provider of 400,000 jobs. |
