This AGRODEP Technical Note provides a literature review on the topic of estimation of demand and supply elasticities. To this end, it starts the discussion by summarizing the main facets of production theory and consumer theory to introduce the concept of elasticities, with examples of di fferent types of elasticities most utilized in the literature. Next, it discusses the identi fication problem in estimating elasticities, i.e. the issue of having to solve for unique values of the parameters of the structural model from the values of the parameters of the reduced form of the model. It summarizes various methodologies employed in the literature to solve this problem and gives practical examples. These solutions include, but are not limited to, using instrumental variables, adopting a recursive structure, holding demand constant, and imposing inequality constraints in order to restrict the domain of estimates.

We present a new framework to identify demand and supply elasticities of agricultural commodities using yield shocks - deviations from a time trend of output per area, which are predominantly caused by weather fluctuations. Demand is identified using current-period shocks that give rise to exogenous shifts in supply. Supply is identified using past shocks, which affect expected future prices through inventory accretion or depletion. We use our estimated elasticities to evaluate the impact of ethanol subsidies and mandates on world food commodity prices, quantities, and food consumers' surplus. The current US ethanol mandate requires that about 5 percent of world caloric production from corn, wheat, rice, and soybeans be used for ethanol generation. As a result, world food prices are predicted to increase by about 30 percent and global consumer surplus from food consumption is predicted to decrease by 155 billion dollars annually. If a third of the biofuel calories are recycled as feed stock for livestock, the predicted price increase scales back to 20 percent. While commodity demand is extremely inelastic, price response is muted by a significant supply response that is obscured if futures prices are not instrumented. The resulting expansion of agricultural growing area potentially offsets the CO2 emission benefits from biofuels.

Excerpt from Summary and Evaluation of the Philippines: Long-Term Projection of Supply and Demand for Selected Agricultural Products; With Implication for Us Exports Imports from the United States and other foreign sources accounted for a significant volume of all eight selected commodities and their products during the 1955 - 61 period. Nevertheless, no imports of milled rice, shelled corn, wheat flour, and tobacco are projected for either 1965 or 1975 (tables 4 and By 1965, imports of wheat flour are projected to shift completely to wheat grain. By 1975, imports of meat and meat products are projected to shift al most completely from processed and canned meats to livestock for slaughter and fresh and frozen meats. Cotton imports will shift from cotton products to raw cotton. The above brings into focus some major implications for U. S. Agricultural exports. By 1975, Philippine imports of the selected agricultural commodities from the United States are expected to experience a net increase of over million from the 1955-57 average. This includes import gains of approximately million for raw cotton, million for milk and dairy products, million for wheat, and million for tallow. Offsetting these gains were losses of nearly $6 million for leaf tobacco (not including cigarettes), over $3 million for meat and meat products, million for shelled corn, and million for milled rice. A loss is also expected (if million for cotton textiles and million for tobacco products (cigarettes only).
