| A watershed based model, the Soil and Water Assessment Tool (SWAT), along with transfer coefficients is used to assess alternative principles of allocating nutrient load reduction in the Raccoon River watershed in central Iowa. Four principles are examined for their cost-effectiveness and impacts on water quality: absolute equity, equity based on ability, critical area targeting, and geographic proximity. Based on SWAT simulation results, transfer coefficients are calculated for the effects of nitrogen application reduction. We find both critical area targeting and downstream focus (an example of geographic proximity) can be more expensive than equal allocation, a manifestation of absolute equity. Unless abatement costs are quite heterogeneous across the... |

| In this paper, we use data from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) survey of households in Burkina Faso, to assess market efficiency. Two methods based on testable implications of the Agricultural Household Model (AHM) are used. The first is based on the observation that if markets clear at prevailing prices, the household labor allocation will be such that shadow wages equate to market wages... The second looks for significance of household structural parameters on labor demand ... The remainder of the paper is organized as follows. In Section II, we provide a brief review of the Agricultural Household Model, highlighting the effect of market failure on separability and the role of shadow prices. Section... |

| made in one situation to related circumstances. The benefit transfer process is typically reliant on the availability of a number of source studies which have appropriate levels of reliability and relevance to the issue of interest. However, the limited number of non-market valuation studies to draw on for source values currently limits the benefit transfer process. In this paper, an alternative approach to benefit transfer is outlined where a series of valuation studies were specifically performed to build a reference data base of values for benefit transfer purposes. The choice modelling technique was used to estimate community values for protecting soil, water and vegetation stocks in Queensland, Australia, where both state and regional populations were... |

| This study examines the impact of farmland investments on the risk-efficiency of mixed asset portfolios. Traditional asset classes considered available for investment include various equity market indices, commercial REITs, corporate bonds of investment- and sub investment grade, government bonds and treasury bills, corporate bonds, ex-U.S. equity indices, short term interest rate indexes, and commodity investments. Unlevered farmland returns were constructed at the state level as the sum of cash rent and capital gains less property taxes as a fraction of asset values. In addition, a unique, high quality data set comprised of the returns to all managed farmland properties in the NCREIF Farmland Index was also considered. A traditional optimal E-V... |

| Enterprise diversification is a self-insuring strategy used by farmers to protect against risk. This paper examines the impact of various farm, operator, and household characteristics on the level of on-farm diversification. Results provide evidence that larger farms are more specialized. Also, farmers who participate in off-farm income and farms located near urban areas are less likely to diversify. Additionally, results also show a significant positive relationship between diversification and farm/crop insurance and sole proprietorships. Finally, there is also evidence that farms that received government payments are more diversified than their counterparts. |

| Measurement of entire supply chain performance is an important issue, because it allows for "tracking and tracing" of efficacy and efficiency failures and leads to more informed decision-making with regards to chain organization. The ultimate aim of implementing a performance measurement system is to improve the performance of the organization. If supply chains can get their performance measurement right, the data they generate will tell them where they are, how they are doing, and where they are going. The choice of appropriate supply chain performance indicators is rather complicated due to presence of multiple inputs and multiple outputs in the system. This issue becomes even more problematic in the field of food and agribusiness due to specific... |

| Suboptimal supply of food and agricultural traceability is framed in a transaction cost analysis. We propose a model that considers the variables of opportunism potential, agency costs, uncertainty, asset specificity, frequency, and transaction costs. The model is then applied to the development of a typology of feasible governance modes – market, hybrid, firm, or public bureau, considering levels of transaction costs and competencies of private firms. Theoretical and practical implications are discussed and future research opportunities are suggested. |

| Food quality has become an increasing concern in the public health arena over recent years. Food manufactures and processors hygiene performance plays a crucial part in producing safer food products. While there are inspections assessing plants' hygiene performance, there is little direct communication of performance measures to consumers. This paper uses survey data to determine consumer preferences among a set of four alternative food labels which report such plant level performance scores. How much information, as well as the format they most prefer, is compared using a range of econometric models. Results show that consumers prefer number scheme, larger volume of quality information and are generally consistent with their preference. These findings... |
