PROTECTING CONTRACT GROWERS OF BROILER CHICKEN INDUSTRY

In case of the tournament based pay-structure, the regulator may be able to increase the welfare of the growers regulating the average performance standard upward. Since she cares about the welfare of the growers, her optimal is to leave part of the surplus to the growers. She does this through setting the relative standard at all others' average inflated by some function of the weight. If there is budgetary constraint then the regulator may not be able to implement this inflated standard.Livestock Production/Industries,

OPTIMAL CONTRACTS FOR EXPLORATION WITH COST RECOVERY OF AN EXHAUSTIBLE NATURAL RESOURCE UNDER ASYMMETRIC INFORMATION

Exploration of an exhaustible resource with cost recovery under asymmetric information about cost is modeled and analyzed employing Principal-Agent theory. Allocation of lower than full information level of effort for the high-cost firms is found socially optimal. However, distortion is less in a two-stage process of exploration and extraction.Resource /Energy Economics and Policy,

ENVIRONMENTAL RISK MANAGEMENT IN THE HORTICULTURAL INDUSTRY

This paper uses environmental risk assessment as a nutrient management planning tool to determine the best set of actions to control nutrient nonpoint source pollution in the horticultural industry. The framework minimizes costs subject to obtaining an environmental risk management score at or below a threshold value.Crop Production/Industries, Environmental Economics and Policy,

Coupled dynamics of flow, microstructure, and conductivity in sheared suspensions

We propose a model for the evolution of the conductivity tensor for a flowing suspension of electrically conductive particles. We use discrete particle numerical simulations together with a continuum physical framework to construct an evolution law for the suspension microsutructure during flow. This model is then coupled with a relationship between the microstructure and the electrical conductivity tensor. The parameters of the joint model are fit experimentally using rheo- electrical conductivity measurements of carbon black suspensions under flow over a range of shear rates. The model is applied to the case of steady shearing as well as time-varying conductivity of unsteady flow experiments. We find that the model prediction agrees closely with the measured experimental data in all cases.Comment: 5 pages, 4 figure
