A Dynamic Principal-Agent Model of Human-Mediated Aquatic Species Invasions AgEcon
MacPherson, Alexander J.; Moore, Rebecca; Provencher, Bill.
This paper presents a dynamic principal-agent model of aquatic species invasions in which a manager, concerned about the spread of invasive species across lakes by boaters, sets interseasonal management controls on a lake-by-lake basis, and boaters make a series of intraseasonal trip decisions to maximize random utility during the course of the season, conditional on the controls imposed by the manager. The results of a simulated invasion of Eurasian watermilfoil (Myriophyllum spicatum) highlight interesting aspects of the optimal management policies under two different management objectives: maximizing boater welfare and minimizing milfoil spread.

Adverse Selection in the Environmental Stewardship Scheme: Does the Higher Level Entry Scheme Design Reduce Adverse Selection? AgEcon
Quillerou, Emmanuelle; Fraser, Rob W..
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on agricultural foregone income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the scheme. However, the Higher Level Scheme (HLS) design includes some features that potentially reduce adverse selection. This paper studies the adverse selection problem of the HLS using a principal agent framework at the regional level. It is found that, at the regional level, the enrolment of more land from lower payment regions for a given budget constraint has led to a greater overall contracted area (and thus potential...

Adverse Selection in the Environmental Stewardship Scheme: Evidence in the Higher Level Stewardship Scheme? AgEcon
Quillerou, Emmanuelle; Fraser, Rob W.; Fraser, Iain.
The Environmental Stewardship Scheme provides payments to farmers for the provision of environmental services based on foregone agricultural income. This creates a potential incentive compatibility problem which, combined with an information asymmetry on farm land heterogeneity, could lead to adverse selection of farmers into the Scheme and therefore reduced cost-effectiveness of the Scheme. This reduced cost-effectiveness would be represented by a systematic overpayment of farmers for the land enrolled into the Scheme, compared to the opportunity cost of production. This paper examines the potential adverse selection problem affecting the higher tier of the Environmental Stewardship, the Higher Level Stewardship, using a principal agent framework combined...

An Incentive System for Salmonella Control in the Pork Supply Chain AgEcon
Backus, Ge B.C.; King, Robert P..
This paper presents a dynamic principal-agent analysis of an incentive system for Salmonella control in the pork supply chain. The incentive system determines quality premiums to the producer, testing frequencies for hogs delivered, as well as charges to the producer for testing and penalties. Using cost estimates and technical parameters, we evaluate the cost effectiveness of plant and farm control measures and trade-offs between prevalence reduction and related costs and gains. We also assess the impact of ownership structure on incentive system parameters and performance for a wide range of prevalence threshold levels. Differences in control actions, bacteriological prevalence and the overall welfare gain for the chain are very small across ownership...

Balancing Grower Protection Against Agency Concerns: An Economic Analysis of Contract Termination Damages AgEcon
Lee, Myoungki; Wu, Steven Y.; Fan, Maoyong.
This study examines legislation that would grant growers termination damages if their contracts are terminated. Our model suggests that, with no contracting frictions, damages would not reduce ex ante efficiency as processors can contract around damages through contract restructuring. Growers would earn less under continuation but would be protected if terminated, although overall expected profits would be unaffected. However, when contracting friction exist, then efficiency losses can occur as processors would be constrained in restructuring contractual incentives to deal with moral hazard. Growers' expected profits would increase while processors' profit would decrease.

Compliance with International Food Safety Standards in Kenya's Green Bean Industry: A Paired Case Study of Small and Large Family Farms AgEcon
Okello, Julius Juma; Swinton, Scott M..
This study uses two farm case studies to explore how Kenyan green bean farmers are meeting European food safety standards. For green bean farmers, the standards increase the fixed costs and the transactions costs of producing beans; the standards also alter how bean quality is assessed. Both the small and the large farm use contracts to protect their specific investments in complying with the standards. However, while the large farm invests in improved facilities using its own equity, the small farm uses a marketing group to spread investment costs and reduce the transaction cost to buyers of monitoring the performance of small units. Green bean buyers face the asymmetric information problem of creating incentives for farmers to comply voluntarily with...

Contract design in agri-environmental schemes with fixed private transaction costs and countervailing incentives AgEcon
Viaggi, Davide.
The aim of this paper is to test the relevance of considering private fixed transaction costs for contract design of Agri-Environmental Schemes, when transaction costs are negatively correlated to marginal compliance costs. In order to do so, a principal-agent model of contract design under adverse selection, including fixed private transaction costs, is developed. The model is applied to the design of payments in the Emilia Romagna region of Italy. The results show that fixed transaction costs in the range of those actually faced by farmers may significantly affect the optimal amount of environmental good to be produced by each farm type. In some cases, fixed transaction costs can even reverse the standard insight that more of a public good should be...

Improving animal health and incentive of hygiene management: Case study in Vietnam OAK
Kono, H; 耕野, 拓一.
Incidence of animal diseases, such as Hog Cholera and Pasteurella, was found in our field survey of 100 pig farmers in T.T.Hue province in Vietnam Thirty five (36%) of surveyed farmers are in poverty according to the 2005 poverty standard in Vietnam. Low income farmer has a large income share from pig production. We suggest that the increase of pig deaths in low income farms will raise the risk to fall into poverty. Improvement of animal health service, especially for low income farmers, will be important for poverty reduction in rural area in Vietnam. Vietnamese pork distribution is in a state of so-called information asymmetry. In order to solve the problem of information asymmetry, it is necessary to fulfill the requirements of incentive compatibility....

Marketing Agreement, Food Safety and Contract Design AgEcon
Liang, Jing; Jensen, Helen H..
Recent outbreaks of food-borne illness related to fruit and vegetables have led to increased concerns about the safety of produce. In response, the industry has adopted marketing agreements to ensure consistency of product safety. Contracts now are widely used between processors and growers to specify product safety attributes. This paper uses a principal-agent model to examine how the inclusion of a marketing agreement influences the behavior of growers and processors under processor-grower contracts. We conclude that: (1) the processor offers a contract with a higher premium and a lower base payment under the contract with a marketing agreement (2) contract parameters change in similar manner under the two contracts (3) under a contract with a marketing...
