Projections of world food demands hinge critically on the underlying functional form used to predict future demands. Simple functional forms can lead to unrealistic projections by failing to capture changes in income elasticities of demand as consumer becomes wealthier. This paper compares...

Technical dependencies as well as data constraints limit our ability to allocate inputs across sectors and hence our ability to measure sectoral productivity. We adapt a directional measure of efficiency to the measurement of sector-specific productivity that does not require allocating all...

Many individuals are predicting a "second green revolution" in agriculture from the introduction of growth stimulants into the livestock industries. An economy-wide approach is used to determine the affects on prices and quantities of introducing growth stimulants in the domestic dairy and pork...

International cross-section demand systems have not been tested on their ability to accurately predict within country consumption expenditures. This paper reports on such a validation exercise for the case of food budget share predictions across expenditure percentiles within Bangladesh.

"Program" yields for individual farmers are utilized in determining the amount of deficiency payments individual farmers receive. They have been frozen since the 1985 Food Security Act (FSA). However, some farm groups are pressing for unfreezing these yields so that actual yields could be...

There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of...

La Revista Integración & Comercio del BID incluye artículos referidos a las distintas manifestaciones del proceso de integración en América Latina y el Caribe, a la integración hemisférica y, también, a los procesos con igual orientación que se llevan a cabo en otras partes del mundo....

The CES is generalized by extension of the work of Hanoch (1975) resulting in implicit, direct and indirect relationships between utility and consumption. Expressions for substitution and income elasticities are developed and observed to be variable, rather than constant as in the CES case.
