Despite the common questions regarding any new crop technology, the new seeds were rapidly adopted. This study examines the characteristics of adopters, as well as yield and weed control cost changes, using survey results from Delaware farmers at the start of the 2000 season. Duration analysis reveals that earlier-adopting farmers had larger farms and tended to use computers for financial management, while regression analysis shows significantly lower weed control costs and, to a lesser extent, higher yields for GE soybeans. http://ageconsearch.umn.edu/handle/31259 Title: County Amenities and Net Migration <br/> <br/>Authors: Rupasingha, Anil; Goetz, Stephan J. <br/> <br/>Abstract: U.S. county-level net migration data and a general spatial model are used to examine the effects of various amenities on migration decisions. Results suggest that higher county cancer risks and the presence of superfund sites in a county, or a higher ranking on the Environmental Protection Agency's hazard ranking system, reduce the relative attractiveness of a county to prospective migrants, while natural amenities on balance attract migrants, ceteris paribus. The results also reveal spatial dependence among contiguous counties in terms of net migration behavior. http://ageconsearch.umn.edu/handle/31260 Title: Farm Return and Land Price Effects from Environmental Standards and Stocking Density Restrictions <br/> <br/>Authors: Weersink, Alfons; Devos, Greg; Stonehouse, Peter <br/> <br/>Abstract: This study assesses the economic and environmental effects to hog finishing farms from residual taxes/standards and restrictions on manure application and stocking density. Economic effects are measured in terms of net farm income and land prices, while levels of ammonia and excess nitrogen and phosphorus proxy the environmental effects. Any environmental policy requiring the need for additional land comes at a small cost to farmers who have access to adequate neighboring land. If this is not the case, then manure application and stocking density restrictions are expensive since the producer is basically forced to either purchase land or reduce hog production levels. http://ageconsearch.umn.edu/handle/31261 Title: Abstracts of Selected Papers; NAREA Annual Meetings, Halifax, Nova Scotia, June 20-23, 2004 http://ageconsearch.umn.edu/handle/31262 Title: Contingent Valuation, Hypothetical Bias, and Experimental Economics <br/> <br/>Authors: Murphy, James J.; Stevens, Thomas H. <br/> <br/>Abstract: Although the contingent valuation method has been widely used to value a diverse array of nonmarket environmental and natural resource commodities, recent empirical evidence suggests it may not accurately estimate real economic values. The hypothetical nature of environmental valuation surveys typically results in responses that are significantly greater than actual payments. Economists have had mixed success in developing techniques designed to control for this "hypothetical bias." This paper highlights the role of experimental economics in addressing hypothetical bias, and identifies a gap in the existing literature by focusing on the underlying causes of this bias. Most of the calibration techniques used today lack a theoretical justification, and therefore these procedures need to be used with caution. We argue that future experimental research should investigate the reasons hypothetical bias persists. A better understanding of the causes should enhance the effectiveness of calibration techniques. http://ageconsearch.umn.edu/handle/31263 Title: Socioeconomics of Individual Transferable Quotas and Community-Based Fishery Management <br/> <br/>Authors: Copes, Parzival; Charles, Anthony <br/> <br/>Abstract: In many fisheries around the world, the failures of centralized, top-down management have produced a shift toward co-management—collaboration and sharing of decision making between government and stakeholders. This trend has led to a major debate between two very different co-management approaches—community-based fishery management and market-based individual transferable quota management. This paper examines the debate over the relative merits of these models and undertakes a socioeconomic analysis of the two approaches. The paper includes (1) an analysis of differences in the structure, philosophical nature, and underlying value systems of each, including a discussion of their treatment of property rights; (2) a socioeconomic evaluation of the impacts of each system on boat owners, fishers, crew members, other fishery participants, and coastal communities, as well as the distribution of benefits and costs among fishery participants; and (3) examination of indirect economic effects that can occur through impacts on conservation and fishery sustainability. The latter relate to (a) the conservation ethic, (b) the flexibility of management, (c) the avoidance of waste, and (d) the efficiency of enforcement. The paper emphasizes the need for a broader approach to analyzing fishery management options, one that recognizes and properly assesses the diversity of choices, and that takes into account the interaction of the fishery with broader community and regional realities. http://ageconsearch.umn.edu/handle/31264 Title: Integrating Farmer Decision Making to Target Land Retirement Programs <br/> <br/>Authors: Yang, Wanhong; Isik, Murat <br/> <br/>Abstract: This study develops a model to examine the impacts of uncertainty about crop production and irreversibility of program participation on determining land rental payments and least-cost land retirement targeting in the Conservation Reserve Enhancement Program (CREP). Results show that under risk aversion only, the marginal cost of abatement and the average land rental payment are less than those under risk neutrality. However, under uncertainty and irreversibility, the marginal cost of abatement and the average land rental payment are considerably higher than those under risk neutrality or risk aversion only. It is important to incorporate uncertainty and irreversibility into the design of land rental payments and in determining participation constraints. http://ageconsearch.umn.edu/handle/31265 Title: ITQs and Community: An Essay on Environmental Governance <br/> <br/>Authors: McCay, Bonnie J. <br/> <br/>Abstract: Two important new directions in resource and environmental management are increased reliance on market mechanisms on the one hand, and on greater participation by local communities on the other. In fisheries, market-based management is found mainly in the "cap-and-trade" systems known as individual transferable quotas (ITQs). ITQs are effective in achieving certain economic goals but often with undesirable social costs, leading to the view that they are antithetical to community-based management. However, ITQ systems have been adapted to mitigate community losses. In addition, social resistance to ITQs has encouraged the development of innovative programs in community-based fisheries management. http://ageconsearch.umn.edu/handle/31266 Title: Cover and Contents Pages <br/> <br/>Abstract: Includes: Editorial Information and Contents Pages http://ageconsearch.umn.edu/handle/31267 Title: A Note on the Reliability Tests of Estimates from ARMS Data <br/> <br/>Authors: Kim, C.S.; Hallahan, C.; Lindamood, W.; Schaible, G.; Payne, J. <br/> <br/>Abstract: USDA uses the concept of "publish-ability" rather than statistical reliability of an estimate for quality validation of USDA estimates, which is solely based on the sample size and the coefficient of variation (CV). We demonstrate conceptually how the reliability of the sample mean can be tested by estimating the upper and lower bounds of the confidence interval for an unknown population mean using the CV. However, the reliability test for the sample mean can be made only under the normality assumption. USDA multiple-way Agricultural Resource Management Survey (ARMS) estimates are used to illustrate the relative measure of precision for sample-based estimators. http://ageconsearch.umn.edu/handle/31268 Title: A Conjoint Analysis of Public Preferences for Agricultural Land Preservation <br/> <br/>Authors: Duke, Joshua M.; Ilvento, Thomas W. <br/> <br/>Abstract: Public preferences for the nonmarket services of permanently preserved agricultural land are measured and compared using conjoint analysis. The results from a survey of 199 Delawareans suggest environmental and nonmarket-agricultural services are the most important preserved-land attributes. Results also suggest that open space associated with wetlands on farms is neither an amenity nor a disamenity. On the margin, preserved parcels with agricultural and environmental attributes provide net benefits, which may exceed $1,000,000 for a 1,000-acre parcel. Preserved forestland provides benefits per acre that are statistically equivalent to cropland, though forestland may be less expensive to preserve. http://ageconsearch.umn.edu/handle/31269 Title: Risk Management Strategies in Humid Production Regions: A Comparison of Supplemental Irrigation and Crop Insurance <br/> <br/>Authors: Dalton, Timothy J.; Porter, Gregory A.; Winslow, Noah G. <br/> <br/>Abstract: Recent federal agricultural programs have accelerated the devolution of enterprise risk management responsibility from the state to individual producers. Using a biophysical simulation model, the risk management benefits of federal crop insurance and supplemental irrigation are derived and compared to uninsured rainfed crop production in an expected utility framework. Federal crop insurance programs are inefficient at reducing producer exposure to weather-related production risk in humid regions, and the risk management benefits from supplemental irrigation are found to be scale and technology dependent. Environmental policies that regulate resource development will increase the investment cost of irrigation alternatives and reduce economic feasibility. http://ageconsearch.umn.edu/handle/31270 Title: How Institutions Affect Outcomes in Laboratory Tradable Fishing Allowance Systems <br/> <br/>Authors: Anderson, Christopher M. <br/> <br/>Abstract: The objective of this paper is to illustrate that economic institutions matter, i.e., that different rules of trade present different incentives for bidding, asking, and trading in new markets, and that these different incentives lead to different price discovery patterns, which yield materially different outcomes. In a laboratory tradable fishing allowance system, when trade takes place through a double auction, which parallels an institution common in extant tradable allowance systems, markets are characterized by high volatility, and equilibrium does not obtain. However, when only leases, and not permanent trades, are permitted in the early periods, volatility is significantly reduced and equilibrium obtains. This dependence of equilibration and outcomes on institutions implies policyoriented economists must consider institutions in designing new market-based management systems. http://ageconsearch.umn.edu/handle/31271 Title: The Obligations of a Policy Economist <br/> <br/>Authors: Portney, Paul R. http://ageconsearch.umn.edu/handle/31272 Title: End Materials <br/> <br/>Abstract: Includes: NAREA Distinguished and Honorary Life Members; Presidents 1955-2004; Editors of the ARER, 1972-2004; NAREA Constitution and By-Laws; ARER Reviewers July 2003-August 2004; ARER Guidelines for Manuscript Submission http://ageconsearch.umn.edu/handle/31273 Title: Agricultural Contracting and the Scale of Production <br/> <br/>Authors: Key, Nigel <br/> <br/>Abstract: This study presents evidence that contracting is positively associated with the scale of production for six major U.S. agricultural commodities. Specifically, contract producers tend to operate at a larger scale than do independent producers, and the likelihood of an operation contracting increases with its scale. This relationship is strongest in the cattle and hog sectors, where it persists even among large commercial operations. Six theoretical explanations for the observed correlation between scale and contracting are proposed, including imperfect capital markets, contractor transaction costs, input leverage, grower risk aversion, asset specificity, and technological change. Information from five annual national surveys is used to examine the validity of three of the proposed mechanisms. http://ageconsearch.umn.edu/handle/31268 Title: A Conjoint Analysis of Public Preferences for Agricultural Land Preservation <br/> <br/>Authors: Duke, Joshua M.; Ilvento, Thomas W. <br/> <br/>Abstract: Public preferences for the nonmarket services of permanently preserved agricultural land are measured and compared using conjoint analysis.
