Abstract: Animal agriculture faces pressures from government regulations and private buyer standards, including those related to labeling. This presentation will review economic relationships for several important issues related to poultry, pork, beef and milk industries. These issues have a common theme: widespread concerns about farm or food system practices are based on misperceptions or misinterpretations. Also, that changes in practices and product characteristics have been imposed by government regulation or intermediate buyer standards that limit consumer choices, rather than by effective market demand by end use consumers.
Among the most significant implications of these trends in animal agriculture are disincentives for application of science and technology to agricultural and food practices. Such disincentives for innovation may foster slower farm and food system productivity growth, slower declines in food prices, slower improvements in food safety, and slower reductions in food waste. In rich, relatively well-fed economies the impacts are substantial but affect a relatively small part of the economy and a small share of most consumer budgets. Among the poor of the world, the consequences are vital and include less nutritious diets and resultant health threats for a billion people.

"Willingness to Pay for Ethanol in Motor Fuel: Evidence from Revealed and Stated Preference for E85"The relative preferences of motorists for E10 and E85 in different regions of the United States were estimated. An intercept survey of motorists with flex-fuel vehicles at E85 fuel stations in IA, CO, OK, AR and CA was conducted. A hypothetical scenario was proposed to each motorist where either the price of the fuel selected (not selected) was increased (decreased). Fuel preferences were estimated using both the revealed preference data from observed choices and the stated preference date from the hypothetical price scenario. We find that motorist significantly discount E85 compared to E10 even when adjusting for the different energy content of the two fuels and that the distribution of willingness to pay for E85 does not vary significantly between regions, except that flex motorists in California are willing to pay more for E85.

"The Value of Social Capital in Cropland Leasing Relationships"In the U.S. economy, informal bargaining between persons for services or assets of relatively high value is uncommon. However, there is one example encountered frequently in agriculture: the cropland lease. Many farmers rent at least a portion of their cropland and typically no formal markets exist for pricing land. This reliance on informal bargaining for the primary capital asset in farming suggests lease rates and the relationship between landowner and tenant have significant economic implications. If the existence of a long-lived and close relationship affect the rates at which the land is leased, then, cropland leases offer a unique test of the theory of social capital.

"Why Choice Matters and Why it Doesn't: An Application to Food Policy"
Abstract: In the attempt to curb the obesity crisis, policymakers are taking ever stronger measures. Recently this has resulted in several high-profile cases of backlash, with consumers complaining that their choices are being limited. Economic models of behavior predict that consumers will respond to changes in price in a way that is independent of the source of the price change. Yet research indicates that consumers that are emotionally attached to a consumption good or other behavior might respond with resistance when policies threaten their consumption or behavior. Using both survey and experimental data, we demonstrate how such emotional responses can create hidden costs to policy implementation that could not be detected using standard welfare economic techniques. We propose a partial equilibrium model of emotional response to policy whereby preferences are endogenous to policy choices. We propose that confrontational policies (such as a tax or quota) increase the marginal utility for a good, and that validating policies (such as a subsidy) also increases the marginal utility for a good. A social planner that ignores potential emotional responses to policy changes may unwittingly induce significant dead weight loss. Using our model, we propose a feasible method to determine if emotional deadweight costs exist, and to place a lower bound on the size of these costs.

"Causes and Consequences of Open Space in U.S. Urban Areas"
Abstract: The large variation in the share of land in open space across U.S. urban areas raises some interesting questions: a) what are the key factors that determine the amount of open space in an urban area? b) how does open space conservation affect property values and local public finance and services? and c) is the existing amount of open space in U.S. urban areas socially optimal? In this paper, we conduct theoretical and empirical analysis to address these issues. Results suggest that a significant share of U.S. urban areas have too little open space in the sense that even if additional open space would not provide any amenities, it would still increase total land values and social welfare. On the other hand, for more than 10% of U.S. urban areas, the total value of environmental benefits from open space must be at least as large as the total land value to justify for the amount of open space they have. Some of these urban areas likely have too much open space.

Abstract: High corn prices cause more land to be planted to corn, which increases the use of nitrogen fertilizer. Some of this nitrogen flows into waterways and causes serious environmental damage. We estimate that nitrogen losses are highly inelastic with respect to crop prices, but that the absolute losses can still be large. Our results suggest that changes in corn and soybean prices due to the U.S. ethanol mandate have expanded the size of the hypoxic zone in the Gulf of Mexico by roughly 288 square miles on average. To obtain these estimates, we use a panel of field-level crop data derived from satellite imagery. We merge these data with predictions from the Soil and Water Assessment Tool (SWAT) to estimate nitrogen losses by field. Our econometric model allows for substantial spatial heterogeneity, which is important for reducing bias in dynamic panel estimates and accounting for possible correlation between acreage response to price and nitrogen losses.

Abstract: The Federal Crop Insurance program has expanded dramatically over the past two decades—from $140 million in subsidies and 84 million acres covered to nearly $10 billion in subsidies and 260 million acres covered. The effect this has had on farmers' credit demand and investment behavior is unclear. Self-selection and market dynamics have masked the direct effect of crop insurance. This paper uses numerous changes to the crop insurance program to isolate crop insurance's direct effect on credit demand and, ultimately, investment. I find that crop insurance increases debt holdings—suggesting that farmers are transferring risk to the taxpayer. Crop insurance also causes farm investment to increase, suggesting that the program may also solve market failures.
January 31, 3:00 in 210 Filley Hall - Sunil Dhoubhadel, PhD candidate, UNL Department of Agricultural Economics
Abstract: Hertel et al. (2010) examine the global impact of increasing the US corn ethanol production as a result of the 2015 conventional mandate in the RFS. Specifically, they examine the impact on global land use changes and resulting changes in global greenhouse gas (GHGs) emissions. In this extension of Hertel et al. (2010), the global impacts of both conventional and advanced mandate for 2015 are examined. The analysis entails comparison of the results with the Hertel et al. (2010) using GTAP-BIO model.
The results from this extension indicate sugarcane ethanol and biodiesel may not result in less CO2 emissions. This result is contrary to popular opinion that these biofuels produce less GHGs emissions. The huge global land use changes associated with the implementation of the advanced biofuels mandate which mainly comprise of sugarcane ethanol and biodiesel are the primary drivers of this result.

Abstract: We examine the decision to join and contribute to an association by agents with different productivity. We model and solve a game that explains investments to form social capital which can produce club goods for members or influence industry-wide policy. Association products and government regulation affect membership and contribution decisions. Government influenceability affects the decisions also, but varies with agent productivity and association output. Often, an increase in government influenceability increases social capital in associations composed of high productivity agents because they prefer to influence policy while low productivity agents focus on production.
February 21, 3:00 in 210 Filley Hall - Cory Walters, University of Nebraska-Lincoln "Revenue Risk with Crop Insurance and Forward Contracting"
Abstract: Crop insurance, a government program, and futures markets, a privately operated program, exist to help agricultural producers manage income risk. Using producer's historical yield data and futures market information; we investigate the income risk impact from these programs. Results suggest that income protection crop insurance policy and forward contracting complement each other. For 2012, a revenue protection crop insurance policy with enterprise units and 80% coverage level reduces income risk is by $333 per acre and increases expected income by about $24 per acre, which is due to the presence of the subsidy, over no insurance or hedging.

Abstract: There is an abundant supply of corn stover in the U.S. that remains after grain is harvested which could be used to produce cellulosic biofuels mandated by the current Renewable Fuel Standard (RFS). This research integrates the Soil Water Assessment Tool (SWAT) watershed model and the DayCent biogeochemical model to investigate water quality and soil greenhouse gas flux that results when corn stover is collected from alternative cropping systems. Together with economic estimates of the cost of each alternative, multiple watershed-scale optimizations are performed for individual pollutant-cost minimization criteria; we compare these results with a purely economic optimization that maximizes stover production at the lowest cost without taking environmental impacts into account. We illustrate tradeoffs between cost and different environmental performance criteria, assuming that nutrients contained in any stover collected must be replaced. The key finding is that stover collection using the practices modeled results in increased contributions to atmospheric greenhouse gases and sediments to waterways while reducing nitrate and total phosphorus relative to the status quo without stover collection. Our results suggest that additional information is needed about (i) the level of nutrient replacement required to maintain grain yields and (ii) cost-effective management practices capable of reducing soil erosion when crop residues are removed in order to avoid contributions to climate change and water quality impairments as a result of using corn stover to satisfy the RFS.

Abstract: For decades, earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favouring their farmers with import barriers and subsidies. Both sets of policies reduced global economic welfare and agricultural trade, and almost certainly added to global inequality and poverty. Progress has been made over the past three decades in reducing agricultural protection in high-income countries and agricultural disincentives in developing countries, but the propensity of governments to insulate their domestic food market from fluctuations in international prices has not waned. Both food-importing and food-exporting countries engage in insulating behaviour, which contributes to the amplification of international food price fluctuations yet does little to advance their national food security. Thus much scope still remains to improve economic welfare and to reduce poverty by removing remaining trade distortions. This Lecture will summarize indicators of these trends and fluctuations in farm trade barriers before examining what unilateral, regional or multilateral trade arrangements, together with complementary domestic measures, could help advance global food security without risking sociopolitical unrest.

Title: "The Effect of Fast Food Restaurants on Childhood Obesity"
Paper: The Effect of Fast-Food Restaurants on School-Level Obesity
Abstract: We analyze the effect of the number of fast food restaurants at different distances from public schools in Arkansas on school-level obesity rates. We use instrumental variable estimation with fast-food restaurant proximity being instrumented by proportion of the population within the 15 to 24 year-old age group and nearness of the school to major highways. Although statistical evidence of the causal effect is mixed, results generally suggest that fast-food restaurants near schools are likely contributing to childhood and adolescent obesity. The impact of fast-food restaurants is greatest when they are within a quarter of a mile of schools and this impact declines as distance between the school and fast-food restaurants increases. The magnitudes of this impact are robust but statistical significance varied depending on model specification.

Title: "An Analysis of Selectivity in the Productivity Evaluation of Biotechnology"
Paper: An Analysis of Selectivity in the Productivity Evaluation of Biotechnology: An Application to Corn
Abstract: This paper investigates selectivity bias issues arising in the productivity evaluation of biotech hybrids, with an application to GM corn yield. The analysis is applied to experimental data on Wisconsin corn yields covering the period 1990-2010. Relying on a "Heckman-like" factor that accounts for selectivity, the analysis uncovers evidence of selection bias. It indicates that some of the observed yield advantage associated with GM hybrids is contributed by their conventional genes. This stresses that, even after the widespread adoption of GM corn in the US, traditional breeding still plays an important role in productivity improvements for corn. We also document how rising market concentration of biotech firms has contributed to increasing selectivity bias in corn yield. Our results suggest that current patenting laws may not appropriately differentiate between GM genes and conventional genes.

Title:Transaction Costs in Payment for Environmental Service Contracts
Abstract: Payment for environmental service (PES) contracts area a common means of acquiring public ecosystem goods or services from private landowners. Aside from the well-studied incentive problems with these contracts, such as hidden action and hidden information, a sparsely studied complication is the role of transaction costs in contract initiation and enforcement. This paper quanties both the individual and aggregate impacts of the transaction costs that arise from nonprice contract attributes, such as time requirements contract enrollment and compliance procedures during the contract period. Individual agents were found to incur widely varying transaction costs from these attributes, but on average transaction costs comprise a significant portion of contract willingness-to-accept. At the aggregate level, transaction costs were found to create a significant drain on the cost-effectiveness of contracting, similar in magnitude to theinefficiency created by hidden information

Title: A Theoretical Analysis of Special Safeguards
Abstract: Special safeguards for agriculture are WTO sanctioned tariffs triggered when imports for certain products exceed a predetermined threshold or when price falls below a predetermined floor. This policy tool emerged originally as part of the Uruguay Round Agreement of Agriculture for those nations that agreed to tarrification. A new, but similar special safeguard mechanism (SSM) has been proposed in the ongoing Doha Round for developing nations. The SSM has been highly contentious and commonly blamed for several breakdowns in negotiations. The purpose of this paper is to investigate theoretically the implications of quantity based special safeguards for agriculture in the presence of imperfect competition. The paper presents four models: one involving two foreign firms exporting to a nation without a domestic industry and three versions of a model with one domestic firm and one foreign exporter. Based on the market situation, the models show how foreign firms will try and lower imports in the current period to prevent triggering the tariff. We also document how firms can store imports in the pre-tariff period and sell in the post-tariff period and on what happens when the domestic firm is allowed to import from a third party.
