Utilizing Contingent Claims to Improve the Management of CAFOs AgEcon
Gramig, Benjamin M.; Skees, Jerry R.; Black, J. Roy.
We propose a market-based approach to reducing the environmental risk posed by concentrated animal feeding operations (CAFOs). The dual problems of hidden information and hidden action faced by policymakers are considered alongside the competing incentives faced by the CAFO manager in a multiple principal-agent setting. A new approach that uses insurance-like contracts is introduced by use of the specific example of a swine operation with a lagoon-based manure management system. Index-based contingent claims contracts in tandem with third-party auditing and waste hauling options are introduced as a complement to regulatory frameworks designed to reduce negative externalities from production.

THE IMPACT OF INFORMATION ON LAND DEVELOPMENT: A DYNAMIC AND STOCHASTIC ANALYSIS AgEcon
Batabyal, Amitrajeet A..
In a two-period model, economists such as K.J. Arrow, A.C. Fisher, and C. Henry, have shown that when development is both indivisible and irreversible, a developer who ignores the possibility of obtaining new information about the outcome of such development will invariably underestimate the benefits of preservation and hence favor development. In this note, I extend the AFH analysis in two directions. I model the land development problem in a dynamic framework, explicitly specifying an information production function. In such a setting, I then ask and answer the question concerning when development should take place. Forthcoming in Journal of Environmental Management

Corporate and Consumer Social Responsibilities: Label Regulations in the Lab AgEcon
Etile, Fabrice; Teyssier, Sabrina.
Although consumer attitudes toward corporate social responsibility are positive, socially responsible (SR) products are far from gaining significant market shares. Information asymmetries have been identified as one of the factor contributing to this attitude-behaviour gap, because social responsibility is a credence attribute. Signalling may remedy this market failure. We use an experimental posted offer market to investigate the impact of various regulatory requirements for labels on sellers’ choice to supply SR products and to signal it, and on buyers’ choice of ethical quality. Three treatments are tested: label certification by a third-party, “cheap-talk signalling” with random monitoring and with or without reputations. Individual social preferences...

Do Farmers Value The Environment? Evidence from the Conservation Reserve Program Auctions AgEcon
Vukina, Tomislav; Levy, Armando; Marra, Michele C..
The paper uses data from the Conservation Reserve Program (CRP) auctions to elicit farmers' attitudes toward the environment by analyzing their bids. The CRP pays farmers to remove land from production and put it to a conservation use. An interesting aspect of these auctions is that winners are determined by a combination of low bids and environmental scores of individual plots. The results indicate that farmers condition their bids on the strength of their environmental scores and that they consistently value those environmental improvements which are concentrated locally such as reduced soil erosion, while they place less emphasis on those benefits which resemble public goods such as air quality and wildlife habitat.

Optimal Incentives under Moral Hazard and Heterogeneous Agents: Evidence from Production Contracts Data AgEcon
Dubois, Pierre; Vukina, Tomislav.
The objective of this paper is to develop an analytical framework for estimation of the parameters of a structural model of an incentive contract under moral hazard, taking into account agents heterogeneity in preferences. We show that allowing the principal to strategically distribute the production inputs across heterogenous agents as part of the contract design, the principal is able to change what appears to be a uniform contract into individualized contracts tailored to fit agents' preferences or characteristics. Using micro level data on swine production contract settlements, we find that contracting farmers are heterogenous with respect to their risk aversion and that this heterogeneity affects the principal's allocation of production inputs across...

Optimal Share Contracts under Theft AgEcon
de Janvry, Alain; Sadoulet, Elisabeth.
Temptation for tenants to under-report output levels under share contracts is undoubtedly high. There is evidence that theft of product occurs and that this affects the design of share contracts. In this case, the optimal output share is chosen to not only induce effort but also to reduce theft of product, while meeting the landlord's limited liability obligation. The tenant's share thus rises with his desire and ability to steal. The optimal contract allows both residual inefficiency in the provision of effort and residual cheating. This contract is also modified by process utility in cheating, ability of the landlord to supervise, risk of revenge with abusive surveillance, and switch to products less prone to theft.

Receiving incorrect information is costly: Diffusion and accuracy of market information among farmers in northern Ghana AgEcon
Zanello, Giacomo; Shankar, Bhavani; Srinivasan, Chittur S..
The recent adoption of Information Communication Technologies (ICTs, namely mobile phones and radios) in rural areas of Sub- Saharan Africa has brought new evidence that an updated and reliable flow of information can have direct benefits for farmers' welfare. However, if correct market information can benefit the users, incorrect information can be costly. In this study we explore the diffusion (quantity) and the accuracy (quality) of price information among farmers in northern Ghana, with a focus on the role of ICTs.

Analysis of the Constraints to the Development of a Domestic Improved Seed Potato Industry in Mali AgEcon
Diallo, Marthe.
This paper outlines proposed research, using concepts of New Institutional Economics, to identify the factors constraining the emergence of a market for domestically produced improved seed potatoes in Mali. It uses the Principal –Agent model to outline how to investigate the feasibility of developing a domestic seed potato industry in Mali by applying the concepts of efficient contract designs and other institutional arrangements. This research will contribute to the literature on: (a) contract and institutional design in the context of asymmetric information and uncertainty typical of agricultural markets in low-income countries and (b) design of improved seed production systems, particularly for clonal crops, in developing countries. The Malian potato...

Trust and Electronic Commerce in the Agrifood Sector. A Trust Model and Experimental Experiences AgEcon
Fritz, Melanie; Hausen, Tobias; Schiefer, Gerhard; Canavari, Maurizio.
Opportunities coming from electronic commerce provide interesting support options for the Agrifood sector. However, due to the product specific information asymmetry in the agrifood sector, the anonymity of the medium creates a lack of trust increasing transaction costs to engage in e-commerce. This paper develops a trust model for electronic commerce in the agrifood industry allowing for the analysis of trust determinants in traditional agrifood transaction relationships and their transfer to appropriate trust determinants in the e-commerce environment. First experimental results validating the suitability of the model to derive appropriate electronic trust generating elements for a given agrifood transaction environment are presented.

ASSET STORABILITY AND HEDGING EFFECTIVENESS IN COMMODITY FUTURES MARKETS AgEcon
Yang, Jian; Awokuse, Titus O..
This paper examines risk minimization hedging effectiveness for major storable and nonstorable agricultural commodity futures markets. Based on the error correction model – bivariate GARCH frameworks, some evidence is found that the hedging effectiveness is stronger for storable commodities than nonstorable commodities under consideration. The finding illustrates an important difference between storable and nonstorable commodities with regard to their hedging function.

Optimal Incentives Under Moral Hazard and Heterogeneous Agents: Evidence from Production Contracts Data AgEcon
Dubois, Pierre; Vukina, Tomislav.
In this paper we develop an analytical framework for the estimation of the structural model parameters of an incentive contract under moral hazard with heterogeneous agents. Using micro level data on swine production contract settlements, we confirm that contract farmers are heterogenous with respect to their risk aversion and that this heterogeneity affects the principal's allocation of production inputs across farmers. Assuming that contracts are optimal, we obtain estimates of a lower and an upper bound of agents' reservation utilities. We show that farmers with higher risk aversion have lower outside opportunities and hence lower reservation utilities.

Tractors on eBay and Farmers and Consumers Market Bulletin: An Analysis on the Determinants of Price and Price Differences AgEcon
Kostandini, Genti; Mykerezi, Elton; Holland, Liz.
We investigate the determinants of price for tractor auctions on eBay and tractors that are listed in the Farmers and Consumers Market Bulletin (FCMB) in Georgia. Surprisingly, seller reputation is not an important factor while engine hours and the presence of air conditioning appear to influence price on eBay auctions. On average prices for tractors that sold on eBay are not different than those on FCMB. The analysis also suggests that farmers may benefit from the use of online venues.

Why Don't Lenders Finance High-Return Technological Change in Developing-Country Agriculture? AgEcon
Blackman, Allen.
Most of the literature attributes credit constraints in small-farm developing-country agriculture to the variability of returns to investment in this sector. But the literature does not fully explain lenders. reluctance to finance investments in technologies that provide both higher average and less variable returns. To fill this gap, this article develops an information-theoretic credit market model with endogenous technology choice. The model demonstrates that lenders may refuse to finance any investment in a riskless high-return technology--regardless of the interest rate they are offered--when they are imperfectly informed about loan applicants, time preferences and, therefore, about their propensities to default intentionally in order to finance...

Quality Ambiguity and the Market Mechanism for Credence Goods AgEcon
Benner, Dietrich.
With credence goods consumers cannot judge actual quality neither before purchase (ex ante) nor after purchase (ex post). Trust has to replace own examination and verification. Applying Choquet-Expected Utility theory, ageneral model of credence goods is developed wich takes the problem of trust explicitly in its view and generalizes the problem of quality uncertainty on the 'market for lemmons' of Akerlof (1970) to 'quality ambiguity' with credence goods. The model shows the market mechanism only performing well in providing credence goods when consumers' trust in given information is not too low. With trust too low, sellers of credence good will be driven out of the market by trust induced adverse selection. In market equilibrium prices will always be...

Quality Certification by Geographical Indications, Trademarks and Firm Reputation AgEcon
Menapace, Luisa; Moschini, GianCarlo.
We study firm reputation as a mechanism to assure product quality in perfectly competitive markets in a context in which both certification and trademarks are available. Shapiro’s (1983) model of reputation is extended to reflect both collective and firm-specific reputations, and this framework is used to study certification and trademarks for food products with a regional identity, known as geographical indications (GIs). Our model yields two primary results. First, in markets with asymmetric information and moral hazard problems, credible certification schemes reduce the cost of establishing reputation and lead to welfare gains compared to a situation in which only private trademarks are available. Hence, certification improves the ability of reputation...

Governance Issues in the Principal-Agent Framework: Producing Cellulosic Ethanol in Michigan AgEcon
Pandey, Vivek; Shanoyan, Aleksan; Ross, Brent.
This article analyzes the incentives and compensation problems faced by cellulosic ethanol producer and logging firms and the consequent impact on the organization of the wood based cellulosic ethanol industry in the US. The success of this relationship is central to setting up the biofuel industry in Michigan and in the US at large. The theoretical results indicate that specification contract under the principal-agent framework is of limited utility due to’ metering’ problem when the principal contracts with multiple agents for the supply of feedstock.. Alternative arrangements including JVs have the potential to provide close to first best solutions.

Past Performance Evaluation in Repeated Procurement: A Simple Model of Handicapping AgEcon
Albano, Gian Luigi; Cesi, Berardino.
When procurement contracts are awarded through competitive tendering participating firms commit ex ante to fulfil a set of contractual duties. However, selected contractors may find profitable to renege ex post on their promises by opportunistically delivering lower quality standards. In order to deter ex post moral hazard, buyers may use different strategies depending on the extent to which quality dimensions are contractible, that is, verifiable by contracting parties and by courts. We consider a stylized repeated procurement framework in which a buyer awards a contract over time to two firms with different efficiency levels. If the contractor does not deliver the agreed level of performance the buyer may handicap the same firm in future competitive...

The Role of Information Provision as a Policy Instrument to Supplement Environmental Taxes: Empowering Consumers to Choose Optimally AgEcon
Sartzetakis, Eftichios S.; Xepapadeas, Anastasios; Petrakis, Emmanuel.
The present paper examines, within a dynamic framework, the use of information provision as a policy instrument to supplement environmental taxation. We assume that at least a fraction of consumers do not posses the required information to make the optimal choices, and that their behavior at each time period depends on the accumulated stock of information. We show that, as the accumulated stock of information provision increases, both the optimal level of information provided at each period of time and the optimal tax rate decline over time. Our results provide strong evidence in support of information campaigns as a policy instrument to supplement traditional environmental policies. Information provision can shift the demand towards environmentally...

On the Legitimacy of Coercion for the Financing of Public Goods AgEcon
Bierbrauer, Felix.
The literature on public goods has shown that efficient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions efficiency considerations justify that individuals are forced to pay for public goods that they do not value. It is shown that participation constraints are desirable if public goods are provided by a malevolent Leviathan. By contrast, with a Pigouvian planner, efficiency can be achieved. Finally, the paper studies the delegation of public goods provision to a profit-maximizing firm. This also makes participation constraints desirable.

Fundamentals Versus Beliefs under Almost Common Knowledge AgEcon
Karp, Larry S..
Modern economic growth models show that the equilibrium outcome may depend on agents' beliefs (expectations) rather than on economic fundamentals (history). In this situation, the equilibrium is indeterminate. However, if agents have "almost common knowledge" rather than common knowledge about the economic fundamentals, this indeterminacy vanishes in one of these models, under certain restrictions. In this situation, the unique competitive equilibrium can be influenced by government policy, just as in standard models.
