We examine four scenarios for the evolution of the biofuel sector using a partial equilibrium model of the world agricultural sector. The model includes the new Renewable Fuels Standard in the 2007 energy act, the two-way relationship between fossil energy and biofuel markets, and a new trend toward corn oil extraction in ethanol plants. At one extreme, one scenario eliminates all support to the biofuel sector when the energy price is low, while the other extreme assumes no distribution bottleneck in ethanol demand growth when the energy price is high. Of the remaining two scenarios, one considers a pure market force driving ethanol demand growth because of the high energy price while the other is a policy-induced shock with removal of the biofuel tax... |

Estimation risk occurs when parameters relevant for decision making are uncertain. Bayes' criterion is consistent with expected-utility maximization in the presence of estimation risk. This article examines optimal (Bayes') land allocations and land allocations obtained using the traditional plug-in approach and two alternative decision rules. Bayes' allocations are much better economically than the other allocations when there are few sample observations relative to activities. Calculation of certainty equivalent returns (CERs) with estimation risk is also discussed and illustrated. CERs are typically (and incorrectly) calculated with the plug-in approach. Plug-in CERs may be extremely misleading. |

The U.S. pork industry routinely adds antibiotics to rations of weaned pigs both to prevent illness before symptoms emerge and to increase growth rates. The European Union (EU) is in the process of restricting feed use of antibiotics, and the U.S. is currently reviewing the practice. The strategic issue facing U.S. pork producers is whether another food safety dispute with the EU is worthwhile. This paper evaluates the economic impact of such a ban in the U.S. The analysis uses a set of technical assumptions derived from the experience of a similar ban in Sweden and finds such a ban would increase production costs per head between $5.24 and $6.05; net profit would decline $0.79 per head. On the consumer side, the effects of a ban would raise the... |
