Agri-Environmental Policy at the Crossroads: Guideposts on a Changing Landscape AgEcon
Claassen, Roger; Hansen, LeRoy T.; Peters, Mark; Breneman, Vincent E.; Weinberg, Marca; Cattaneo, Andrea; Feather, Peter; Gadsby, Dwight M.; Hellerstein, Daniel; Hopkins, Jeffrey W.; Johnston, Paul V.; Morehart, Mitchell J.; Smith, Mark.
Agri-environmental policy is at a crossroads. Over the past 20 years, a wide range of policies addressing the environmental implications of agricultural production have been implemented at the Federal level. Those policies have played an important role in reducing soil erosion, protecting and restoring wetlands, and creating wildlife habitat. However, emerging agri-environmental issues, evolution of farm income support policies, and limits imposed by trade agreements may point toward a rethinking of agri-environmental policy. This report identifies the types of policy tools available and the design features that have improved the effectiveness of current programs. It provides an indepth analysis of one policy tool that may be an important component of a...

Balancing the Multiple Objectives of Conservation Programs AgEcon
Cattaneo, Andrea; Hellerstein, Daniel; Nickerson, Cynthia J.; Myers, Christina.
Many of the Nation’s conservation programs seek to achieve multiple environmental objectives. Implementing a multi-objective program efficiently requires program managers to balance different environmental and cost objectives. A number of conservation programs use an index approach to prioritize objectives and rank program applications. This approach keeps program objectives distinct and enables program managers to use weights to determine the relative importance of each objective. This report provides empirical evidence on the environmental and cost tradeoffs of different index weighting schemes in USDA’s Conservation Reserve Program (CRP). The analyses take into account both land characteristics and how changes to an index affect producer decisions to...

Benefits of Protecting Rural Water Quality: An Empirical Analysis AgEcon
Crutchfield, Stephen R.; Feather, Peter; Hellerstein, Daniel.
Concerns about the impact of farm production on the quality of the Nation's drinking and recreational water resources have risen over the past 10 years. Because point sources of pollution were controlled first, agricultural nonpoint sources have become the Nation's largest remaining single water-quality problem. Both public and private costs of policies that address the conflict between agricultural production and water quality are relevant, but measuring the off-farm benefits and costs of changing water quality is difficult. Many of the values placed on these resources are not measured in traditional ways through market prices. This report explores the use of nonmarket valuation methods to estimate the benefits of protecting or improving rural water...

Benefits of Safer Drinking Water: The Value of Nitrate Reduction AgEcon
Crutchfield, Stephen R.; Cooper, Joseph C.; Hellerstein, Daniel.
Nitrates in drinking water, which may come from nitrogen fertilizers applied to crops, are a potential health risk. This report evaluates the potential benefits of reducing human exposure to nitrates in the drinking water supply. In a survey, respondents were asked a series of questions about their willingness to pay for a hypothetical water filter, which would reduce their risk of nitrate exposure. If nitrates in the respondent's drinking water were to exceed the EPA minimum safety standard, they would be willing to pay $45 to $60, per household, per month, to reduce nitrates in their drinking water to the minimum safety standard. There are 2.9 million households in the four regions studied (White River area of Indiana, Central Nebraska, Lower...

Better Targeting, Better Outcomes AgEcon
Hansen, LeRoy T.; Hellerstein, Daniel.
A multitude of design decisions influence the performance of voluntary conservation programs. This Economic Brief is one of a set of five exploring the implications of decisions policymakers and program managers must make about who is eligible to receive payments, how much can be received, for what action, and the means by which applicants are selected. The particular issue addressed here is options for targeting program payments to where they can yield the greatest gain.

Challenges Facing USDA’s Conservation Reserve Program AgEcon
Hellerstein, Daniel.
Reductions in maximum Conservation Reserve Program (CRP) acres mandated by the 2008 Farm Act, along with relatively high agricultural commodity prices, could lead to reduced overall environmental benefits and higher CRP costs. ERS is analyzing alternative enrollment policies and practices that could increase environmental benefits per enrolled acre and lower program costs. The effectiveness of changes will depend on improved data and models to more accurately estimate the environmental benefits provided by competing offers to enroll land in the CRP.

Do Farm Programs Encourage Native Grassland Losses? AgEcon
Claassen, Roger; Carriazo, Fernando; Cooper, Joseph C.; Hellerstein, Daniel.
Federal programs may encourage farmers to convert native grasslands—land that has never been cultivated — to production of corn, soybeans, and other crops, leading to potential losses of Northern Plains' native grasslands. Federally subsidized crop insurance reduces risk associated with crops grown on converted grasslands and, over time, increases average returns to production by making crop farming more attractive. Other programs, including Federal disaster assistance and marketing loan benefits, also reduce risk and increase returns to crop production on converted grasslands. While these programs can be important risk management tools for farmers, they may also result in unintended, environmentally damaging actions.

Economic Valuation of Environmental Benefits and the Targeting of Conservation Programs: The Case of the CRP AgEcon
Feather, Peter; Hellerstein, Daniel; Hansen, LeRoy T..
The range of environmental problems confronting agriculture has expanded in recent years. As the largest program designed to mitigate the negative environmental effects of agriculture, the Conservation Reserve Program (CRP) has broadened its initial focus on reductions in soil erosion to consider other landscape factors that may also be beneficial. For example, preserving habitats can help protect wildlife, thus leading to more nature-viewing opportunities. This report demonstrates how nonmarket valuation models can be used in targeting conservation programs such as the CRP.

ESTIMATING PRODUCER'S SURPLUS WITH THE CENSORED REGRESSION MODEL: AN APPLICATION TO PRODUCERS AFFECTED BY COLUMBIA RIVER BASIN SALMON RECOVERY AgEcon
Moore, Michael R.; Gollehon, Noel R.; Hellerstein, Daniel.
Application of the tobit model to estimate economic welfare is transferred from the consumer side to the producer side. Supply functions are estimated for multioutput irrigators in the Pacific Northwest. Empirical procedures are then developed for computing expected producer's surplus from the output supply functions. Confidence intervals for the surplus measures are generated using the Krinsky-Robb method. An experiment predicts decreases in surplus given increases in water pumping cost. The experiment replicates possible increases in hydroelectric prices due to the salmon recovery program in the Columbia-Snake River Basin. Output substitution explains producers' ability to mitigate the effect of the price increases on producer's surplus.

Estimating Water Quality Benefits: Theoretical and Methodological Issues AgEcon
Ribaudo, Marc; Hellerstein, Daniel.
Knowledge of the benefits and costs to water users is required for a complete assessment of policies to create incentives for water quality improving changes in agricultural production. A number of benefit estimation methods are required to handle the varying nature of water quality effects. This report reviews practical approaches and theoretical foundations for estimating the economic value of changes in water quality to recreation, navigation, reservoirs, municipal water treatment and use, and roadside drainage ditches.

FARMLAND PROTECTION: THE ROLE OF PUBLIC PREFERENCES FOR RURAL AMENITIES AgEcon
Hellerstein, Daniel; Nickerson, Cynthia J.; Cooper, Joseph C.; Feather, Peter; Gadsby, Dwight M.; Mullarkey, Daniel J.; Tegene, Abebayehu; Barnard, Charles H..
Public amenities provided by a rural agricultural landscape, arising from open space and farm activity, are important to many citizens and policymakers. Widespread development of farmland in some parts of the country has spawned an expanding array of farmland protection programs by county, State, and Federal governments, as well as by nonprofit organizations. To investigate the relative importance of preserving different amenities, this report examines the enabling legislation of these programs across the 48 contiguous States, and the implementation of these programs in five Northeastern States (Maryland, Massachusetts, New Jersey, Pennsylvania, and Vermont). The report also assesses how farmland protection programs fit into the broader array of rural land...

INCREASED RESERVOIR BENEFITS: THE CONTRIBUTION OF SOIL CONSERVATION PROGRAMS AgEcon
Hansen, LeRoy T.; Hellerstein, Daniel.
The objective of this research is to value soil conservation's impact on reservoirs. Using a model based on replacement cost, we estimate the benefits gained by marginal decreases in soil erosion for more than 75,000 reservoirs across the contiguous States. We aggregate benefits across the reservoirs within each of the 2,111 U.S watersheds in order to produce regional benefit estimates. Results show that a one-ton reduction in soil erosion provides benefits ranging from zero to $1.67. Our estimated model can be used to assess conservation benefits. For example, the lower level of soil erosion in 1997, relative to the 1982 level, preserved $139 million in reservoir benefits.

Modeling Conservation Program Impacts: Accounting for participation using bootstrapping AgEcon
Hellerstein, Daniel.
Many conservation programs, such as the Conservation Reserve Program (CRP), use indices to select offers. When modeling how changes in the index weights effect program outcomes, one must account for the attributes of available land, and which landowners chose to participate. This paper introduces a methodology to account for changes in participation as index weights change. Data on the actual CRP (all offers received) are combined with an artificial population of available lands (based on National Resources Inventory data). Bootstrapping methods are used to calibrate estimates of participation probability, and to account for errors-in-variables when estimating how index scores effect this probability. Preliminary analysis suggests that accounting...

Protecting Rural Amenities Through Farmland Preservation Programs AgEcon
Nickerson, Cynthia J.; Hellerstein, Daniel.
We investigate what farmland preservation programs reveal about the importance of protecting different rural amenities. An extensive content analysis of the enabling legislation of various farmland protection programs suggests wide variation exists in the protection of amenities. An analysis of 27 individual Purchase of Development Rights (PDR) programs' selection criteria suggests these programs favor preserving amenities that are jointly provided by cropland and livestock operations. These PDR selection criteria also reveal unique preferences regarding the spatial patterns of preserved agricultural lands. Variation in relative weights given to protecting most parcel characteristics in PDR programs is not easily explained by factors that characterize...

The Conservation Reserve Program: Economic Implications for Rural America AgEcon
Sullivan, Patrick; Hellerstein, Daniel; Hansen, LeRoy T.; Johansson, Robert C.; Koenig, Steven R.; Lubowski, Ruben N.; McBride, William D.; McGranahan, David A.; Roberts, Michael J.; Vogel, Stephen J.; Bucholtz, Shawn.
This report estimates the impact that high levels of enrollment in the Conservation Reserve Program (CRP) have had on economic trends in rural counties since the program's inception in 1985 until today. The results of a growth model and quasi-experimental control group analysis indicate no discernible impact by the CRP on aggregate county population trends. Aggregate employment growth may have slowed in some high-CRP counties, but only temporarily. High levels of CRP enrollment appear to have affected farm-related businesses over the long run, but growth in the number of other nonfarm businesses moderated CRP's impact on total employment. If CRP contracts had ended in 2001, simulation models suggest that roughly 51 percent of CRP land would have returned...

The Effective Use of Limited Information: Do Bid Maximums Reduce Procurement Cost in Asymmetric Auctions? AgEcon
Hellerstein, Daniel; Higgins, Nathaniel.
Conservation programs faced with limited budgets often use a competitive enrollment mechanism. Goals of enrollment might include minimizing program expenditures, encouraging broad participation, and inducing adoption of enhanced environmental practices. We use experimental methods to evaluate an auction mechanism that incorporates bid maximums and quality adjustments. We examine this mechanism’s performance characteristics when opportunity costs are heterogeneous across potential participants, and when costs are only approximately known by the purchaser. We find that overly stringent maximums can increase overall expenditures, and that when quality of offers is important, substantial increases in offer maximums can yield a better quality-adjusted result.

The Effects of Changing Commodity Prices On the CRP AgEcon
Hellerstein, Daniel; Malcolm, Scott A..
How might increases in commodity prices, along with the acreage reduction mandated in the 2008 Farm Act, impact the Conservation Reserve Program (CRP)? Modeling Strategy The Likely To Bid (LTB) model “restarts” the CRP from scratch. Uses National Resources Inventory data to find parcels “likely” to offer acreage to the CRP Policy scenarios We consider several scenarios, both with and without increases in CRP rental rates. Continuation of current prices, which are well above prices prevalent when most CRP contracts were enrolled Predicted prices due to an increase in biofuels production to 15 billion gallons Expectation that summer 2008 prices will be the norm Findings Continuation of current, relatively high commodity prices would have noticeable...
