The effect of sampling error in estimation of farmers' mean yields for crop insurance purposes is explored using farm-level corn yield data in Iowa from 1990 to 2000 and Monte Carlo simulations. We find that sampling error combined with nonlinearities in the insurance indemnity function will result in empirically estimated crop insurance rates that exceed actuarially fair values by between 2 and 16 percent, depending on the coverage level and the number of observations used to estimate mean yields. Accounting for the adverse selection caused by sampling error results in crop insurance rates that will exceed fair values by between 42 and 127 percent. We propose a new estimator for mean yields based on a common decomposition of farm yields into systemic and... |

As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant processes of a product, has become the accepted procedure to use to determine greenhouse gas emissions of products ranging from transportation fuels, to building materials, to food production (Farrell et al., 2006; Hill et al., 2006; Owen, 2004). The basic motivation of LCA is that, to conduct a fair assessment of the environmental impacts of a product, it is necessary to take into account all of the processes throughout the product’s lifespan, including the extraction... |

In this paper we examine more closely some of the forces that underlie economic growth at the county level. In an effort to describe a much more comprehensive regional economic growth model, we address a variety of different growth hypotheses by introducing a large number of growth related variables. When formulating our hypotheses and specifying our growth model we make liberal use of GIS mapping software to "paint" a picture of where growth spots exist and why. Our empirical estimation indicates amenities, state and local tax burdens, population, amount of agricultural activity, and demographics have important economic growth impacts. |

New quality assurance systems (QASs) are being put in place to facilitate the flow of information about agricultural and food products. But what constitutes a proper mix of public and private efforts in setting up QASs is an unsettled question. A better understanding of private sector incentives for setting up such systems will help clarify what role the public sector might have in establishing standards. We contribute to this understanding by modeling the optimal degree of "stringency" or assurance in a processor's quality control system over procurement of agricultural output when there exists uncertainty about quality. Our model addresses two questions: (1) Should a buyer of agricultural outputs implement a QAS as a way to gain and provide information... |

Conservation program administered by USDA have traditionally been voluntary, with USDDA providing technical and fiscal assistance to farmers. This tradition is continued din the Federal Agriculture Improvement and Reform Act of 1996. Under these programs, farmers commit themselves to adopting a land management practice and, in turn, the government provides technical and financial assistance. Our analysis suggest that these voluntary programs are more efficient than a program that mandates adoption if and only if the per acre social cost of government expenditure under these program is less than the largest per acre farmer loss under the mandatory approach plus the additional implementation and enforcement cost. This necessary and sufficient condition is... |

The production literature has shown that inputs such as fertilizer can be defined as risk-increasing. However, farmers also consistently overapply nitrogen. A model of optimal input use under uncertainty is used to address this paradox. Using experimental data, a stochastic production relationship between yield and soil nitrate is estimated. Numerical results show that input uncertainty may cause farmers to overapply nitrogen. Survey data suggest that farmers are risk averse, but prefer small chances of high yields compared to small chances of crop failures when expected yields are equivalent. Furthermore, yield risk and yield variability are not equivalent. |

The U.S. ethanol industry is lobbying hard for an extension of existing ethanol import tariffs and blenders tax credits before they expire at the end of 2010. The purpose of this study is to examine the likely consequences on the U.S. ethanol industry, corn producers, taxpayers, fuel blenders, and fuel consumers if current policy is not extended. Impacts of different ethanol policies in both 2011 and 2014 were estimated. Estimates were obtained by developing a new stochastic model that calculates market-clearing prices for U.S. ethanol, Brazilian ethanol, and U.S. corn. The model is stochastic because market-clearing prices are calculated for 5,000 random draws of corn yields and wholesale gasoline prices. Key assumptions in this study are that the... |

The conservation compliance provision of the 1985 Food Security Act requires highly erodible land to be cropped according to a locally approved conservation plan. There is overwhelming evidence that conservation compliance has reduced soil erosion. A key issue confronting Congress as they consider 1995 Farm Bill options is the fate of these erosion benefits if commodity programs are eliminated or it the subsidy level is greatly reduced. This study provides policymakers with additional insights into the relationship between conservation tillage practices and government programs by using observed farmer behavior. The central question addressed is: If future program benefits are not tied to conservation practices, will there be a significant decline in the... |

Genetically modified organisms (GMO) crops have become increasingly popular with Iowa farmers over the past few years. The current genetic modifications are focused on pest management technologies. Although there were early efforts by environmental activists to disrupt the adoption of GMO technology, few concerns were raised by U.S. food retailers and consumers. The primary concern was getting European Union (EU) regulatory approval for each GMO crop variety event as late as spring 1999. The situation has changed dramatically in the last few months, and the current situation is highly uncertain. This paper provides the economic perspective on the issues surrounding non-GMO/GMO market segregation, the potential price impacts that may materialize with... |
