Theoretical Background and Empirical Supply Estimates of the U.S. Livestock Sector

摘要

The report documents the theoretical background and the statistical structure of the U.S. livestock supply component that will become part of the U.S. country model in the IIASA linkage system. The methodological framework of the estimated statistical models is presented in Section I. In this section the literature on the capital asset approach to livestock modeling is reviewed and its implications explored. Section II deals with the empirical estimates of the following components of livestock supply: beef (including veal) and dairy, pork, lamb and sheep (including wool production), and poultry (including eggs and turkeys). This section also deals with the empirical estimates of feed demand of corn, barley, sorghum, oats, wheat, roughage and hay, soybean meal and all other oilseed meals. Finally, in Section III, the dynamic properties of livestock supply are described and their implications explored.
