The nation of Ghana, West Africa has a diverse and rich resource base. The country is mainly agricultural, however, with a majority of its workers engaged in farming. Cash crops consist primarily of cocoa and cocoa products, which typically provide about two-thirds of export revenues, timber products, palm oil, coconuts and other palm products, shea nuts, which produce an edible fat, and coffee. Ghana also has established a successful program of nontraditional agricultural products for export, including pineapples, cashews, and pepper. Cassava, yams, plantains, maize, rice, peanuts, pearl millet, and sorghum are the basic foodstuffs. Fish, poultry, and meat also are important dietary staples.
Minerals -- principally gold, diamonds, manganese ore, and bauxite -- are produced and exported. The only commercial oil well has been closed after producing 3.5 million barrels (560,000 m³) over its seven-year life, but signs of natural gas are being studied for power generation, while exploration continues for other oil and gas resources.Offshore oil deposits in potentially significant quantities were recently discovered near cape three points.
Ghana's industrial base is relatively advanced compared to many other African countries. Import-substitution industries include textiles; steel (using scrap); tires; oil refining; flour milling; beverages; tobacco; simple consumer goods; and car, truck, and bus assembly.
Tourism has become one of Ghana's largest foreign income earners (ranking third in 1997), and the Ghanaian Government has placed great emphasis upon further tourism support and development.
As of 2005, Ghana had the world's worst purchasing parity. This means that Ghanaians get less for their money than people from anywhere else. Countries in a similar position include remote Kuwait and Qatar, and notoriously expensive Switzerland, Iceland and Norway. Most third world African countries have exceptionally good parity, though the Republic of Congo has a ratio similar to moderate first world countries; and Angola and Zambia have ratios befitting a country from the second world.

Macro-economic trend
Prime Minister Busia's government (1969-72) liberalized controls to attract foreign investment and to encourage domestic entrepreneurship. Investors were cautious, however, and cocoa prices began declining again while imports surged, precipitating a serious trade deficit. Despite considerable foreign assistance and some debt relief, the Busia regime also was unable to overcome the inherited restraints on growth posed by the debt burden, balance-of-payments imbalances, foreign exchange shortages, and mismanagement.
Although foreign aid helped prevent economic collapse and was responsible for subsequent improvements in many sectors, the economy stagnated in the 10-year period preceding the NRC takeover in 1972. Population growth offset the modest increase in gross domestic product, and real earnings declined for many Ghanaians.

Busia government
To restructure the economy, the NRC, under General Acheampong (1972-78), undertook an austerity program that emphasized self-reliance, particularly in food production. These plans were not realized, however, primarily because of post-1973 oil price increases and a drought in 1975-77 that particularly affected northern Ghana. The NRC, which had inherited foreign debts of almost $1 billion, abrogated existing rescheduling arrangements for some debts and rejected other repayments. After creditors objected to this unilateral action, a 1974 agreement rescheduled the medium-term debt on liberal terms. The NRC also imposed the Investment Policy Decree of 1975--effective on January 1977--that required 51% Ghanaian equity participation in most foreign firms, but the government took 40% in specified industries. Many shares were sold directly to the public.

Acheampong government
Continued mismanagement of the economy, record inflation (more than 100% in 1977), and increasing corruption, notably at the highest political levels, led to growing dissatisfaction. The post-July 1978 military regime led by General Akuffo attempted to deal with Ghana's economic problems by making small changes in the overvalued cedi and by restraining government spending and monetary growth. Under a one-year standby agreement with the International Monetary Fund (IMF) in January 1979, the government promised to undertake economic reforms, including a reduction of the budget deficit, in return for a $68 million IMF support program and $27 million in IMF Trust Fund loans. The agreement became inoperative, however, after the 4 June coup that brought Flight Lieutenant Rawlings and the AFRC to power for 4 months.

Akuffo government
In September 1979, the civilian government of Hilla Limann inherited declining per capita income; stagnant industrial and agricultural production due to inadequate imported supplies; shortages of imported and locally produced goods; a sizable budget deficit (almost 40% of expenditures in 1979); high inflation, "moderating" to 54% in 1979; an increasingly overvalued cedi; flourishing smuggling and other black-market activities; unemployment and underemployment, particularly among urban youth; deterioration in the transport network; and continued foreign exchange constraints.
Limann's PNP government announced yet another (2-year) reconstruction program, emphasizing increased food production and productivity, exports, and transport improvements. Import austerity was imposed and external payments arrears cut. However, declining cocoa production combined with falling cocoa prices, while oil prices soared. No effective measures were taken to reduce rampant corruption and black marketing.

Limann government
When Rawlings again seized power at the end of 1981, cocoa output had fallen to half the 1970-71 level and its world price to one-third the 1975 level. By 1982, oil would constitute half of Ghana's imports, while overall trade contracted greatly. Internal transport had slowed to a crawl, and inflation remained high. During Rawlings' first year, the economy was stagnant. Industry ran at about 10% of capacity due to the chronic shortage of foreign exchange to cover the importation of required raw materials and replacement parts. Economic conditions deteriorated further in early 1983 when Nigeria expelled an estimated 1 million Ghanaians who had to be absorbed by Ghana.
In April 1983, in coordination with the IMF, the PNDC launched an economic recovery program, perhaps the most stringent and consistent of its day in Africa, aimed at reopening infrastructural bottlenecks and reviving moribund productive sectors--agriculture, mining, and timber. The largely distorted exchange rate and prices were realigned to encourage production and exports. Increased fiscal and monetary discipline was imposed to curb inflation and to focus on priorities. Through November 1987, the cedi was devalued by more than 6,300%, and widespread direct price controls were substantially reduced.

Rawlings government
The economy's response to these reforms was initially hampered by the absorption of one million returnees from Nigeria, the onset of the worst drought since independence, which brought on widespread bushfires and forced closure of the aluminium smelter and severe power cuts for industry and decline in foreign aid. In 1985, the country absorbed an additional 100,000 expellees from Nigeria. In 1987, cocoa prices began declining again; however, initial infrastructure repairs, improved weather, and producer incentives and support revived output in the early 1990s. During 1984-88 the economy experienced solid growth for the first time since 1978. Renewed exports, aid inflows, and a foreign exchange auction have eased hard currency constraints.
