In 1966, 90 percent of the cocoa growing areas in Bahia, Brazil had trees more than 30 years old. By 1985 most of the area had been replanted or supplied with new trees. Throughout most of this period there were high or rising cocoa prices, and zero or negative interest rates. High prices and...

Are natural resources a blessing or a curse? The authors present a model in which natural resources have a positive effect on the level of income and a negative effect on its growth rate. The positive and permanent effect on income implies a welfare gain. There is a growth effect stemming from a...

Dracunculiasis (or Guinea worm disease) was endemic in several African countries as well as in India, Pakistan, and Yemen. The past decade, however, has seen a remarkable decline in the incidence of dracunculiasis as a result of the Global Dracunculiasis Eradication Campaign. The authors compare...

Except during the Great Depression, the historical path for per capita Gross Domestic Product (GDP) in the United Stateshas been reasonably stable exponential trend growth, with modest cyclical deviation. Graphically, growth in the United States displays as a modestly sloping, only slightly...

The author, using a neoclassical Solow model, estimates an economy's rate of convergence to its own steady state. Using panel date for a sample of 98 countries, the author applies Chamberlain's (1984) estimation procedures to account for the presence of country-specific effects resulting from...

The author of this report provides cross-country empirical evidence on the relationship between trade and macroeconomic policy and economic growth. He finds that countries following sustainable strategies perform better than those following unsustainable strategies. Indeed, unsustainable...

One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural...

In the past decade the developing countries have tried much harder to achieve macroeconomic stability than they have to eliminate inefficiencies from microeconomic distortions. The author has pursued a relatively new line of inquiry in examining measurement of the social income losses induced by...

The authors examine the empirical evidence in support of the poverty trap view of underdevelopment. They calibrate simple aggregate growth models in which poverty traps can arise due to either low saving or low technology at low levels of development. They then use these models to assess the...
