Evaluating New Beef Production Technologies and Their Impact on the Sustainability of a Grazing System: A Stochastic Dynamic Model AgEcon
Alford, Andrew R.; Cacho, Oscar J.; Griffith, Garry R..
Net feed efficiency (NFE) technology is expected to improve the productivity of grazing systems in Australia's southern beef producing regions. The extended time path required for implementation of this genetic technology into commercial herds and the influence of climatic variability on the pasture base are important issues to address in estimating the benefits of this technology at the farm level. NFE also has the potential to impact on the sustainability of the grazing systems in terms of maintaining adequate pasture cover. These issues are investigated by developing a stochastic dynamic simulation model. The bioeconomic model includes pasture, animal production, herd dynamics and economic sub-models. In this paper the model is presented and the...

ON THE DEMAND FOR A STATE-CONTINGENT, COST-SAVING SEED TRAIT AgEcon
Hennessy, David A.; Saak, Alexander E..
Biotechnology has enriched the strategy set available to crop managers. Suppose a manager faces a decision between applying a pre-emergence pesticide or applying nothing at all. The advent of pesticide tolerance traits in plants admits the possibility of a state-contingent post-emergence application of pesticide. The innovation adds value in large part because it provides the manager with the option to wait for more information. For heterogeneous acre types, the determinants of trait royalties and of crop management strategies in equilibrium are studied. Pest resistance traits have different implications for crop management. Whereas a tolerance trait likely complements information technologies, the addition of a resistance trait may substitute for them.
