This study develops a generic conceptual approach to modeling the livestock sector that provides better coverage of variables to ensure the consistency in the underlying biologics of the model and also provides consistent rules of specification. This approach is applied to modeling the...

The level of aggregation of reported data has limited the proper accounting of live animals in most, if not all, livestock models, making the consistency of their underlying biologics suspect. We develop an econometric methodology to decompose a wide range of aggregate data. This method is...

Many livestock sector models have limited coverage of relevant variables, and are somewhat ad hoc in their choice of what should be specified as behavioral equations. This study develops a generic conceptual approach to modeling the livestock sector that provides consistent rules of...

The common treatment of a separate import demand specification in the literature is usually motivated by product differentiation. Most studies, however, proceed further with a separability assumption between domestic and imported product for data consideration and ease in estimation. In this...

Imports are increasingly becoming a significant source of Japan's pork supply. Japan's share of imports to total consumption increased from 9 percent in 1980 to 24 percent in 1990, reaching a maximum of 44 percent in 1996. Under the World Trade Organization (WTO) safeguard provisions for pork,...

Indonesia’s domestic broiler production has grown rapidly, in part because of a ban on imports of poultry parts and strict inspection and meat certification requirements. Whether Indonesia will continue to protect the domestic broiler sector and import feed grains and other inputs or whether it...

We examined four evolution paths of the biofuel sector using a partial equilibrium worldagricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-wayrelationship between fossil energy and biofuel markets, and a new trend toward corn oilextraction in ethanol plants. At...

The study finds that the emergence and expansion of the ethanol sector was associated with a fundamental transformation of the integration of the energy and agricultural sectors. In particular, the correlation structure between crude oil and grain prices increased dramatically, becoming more...
