Derived demand relationships among four weight categories of feeder cattle entering Texas feedlots and their feed consumed are examined using a generalized McFadden dual cost function. Results demonstrate systematic differences in demand relationships among different weight categories. Positive...

We divide countries into two technology categories: developed and developing. Agricultural efficiency within each technology category was calculated. Cross-category efficiency measures were developed and combined with own-category measures to develop a technical difference index. Results...

In this paper we evaluate the performance of a dynamic model of cattle replacement and culling decisions. We derive the price of cattle when it is treated as a unit of capital and evaluate various rates of adjustment of the cattle herd to determine the length of the cattle cycle. Replacement...

An output distance function conditional on the expansion of a second output is presented. These distance functions are used to calculate distinct relative Total Factor Productivity (TFP) scores for two jointly produced products-livestock and crops for 27 countries. From these, TFP growth and...

The spread of infectious disease among and between wild and domesticated animals has become a major problem worldwide. We analyze the socially optimal management of wildlife and livestock, including choices involving environmental habitat variables and on-farm biosecurity controls, when wildlife...

Antimicrobial drugs are fed to hogs at sub-therapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study describes the extent to...

Antimicrobial drugs are fed to hogs at sub-therapeutic levels to prevent disease and promote growth. However, there is concern that the presence of antimicrobial drugs in hog feed is a factor promoting the development of antimicrobial drug-resistant bacteria. This study uses a sample-selection...

We estimated a wholesale demand system for beef, pork, lamb, chicken, and turkey using quarterly U.S. data and a dynamic, CBS system (Keller and Van Driel). The CBS system is a differential system, which means that it might be more appropriately applied in those situations where the data have...
