Empirical Assessment of Baseline Conservation Tillage Adoption Rates and Soil Carbon Sequestration in the Upper Mississippi River Basin AgEcon
Kurkalova, Lyubov A.; Kling, Catherine L..
The study proposes a methodology for developing a carbon sequestration baseline attributable to the current use of conservation tillage. An integral component of the methodology is the explicit acknowledgment that there is an uncertainty in the baseline because of the uncertainty associated with the use of econometrically estimated models. The results of applying the method to a major crop production area, the Upper Mississippi River Basin in the central United States, are reported for two major crops in the region, corn and soybeans. The approach to estimation of the baseline should be readily transferable to other geographic areas and conservation practices.

A POLLUTION TRADING SYSTEM WITH COST ASSYMETRY: An Application to Nonpoint Source Trading in the Boone River Watershed AgEcon
Valcu, Adriana M.; Kling, Catherine L..
The goal of watershed scale analysis is to assign to each field unit the best set of agricultural practices in order to achieve a maximum outcome from both environmental and economic perspectives. Watershed physically based models linked to multiobjective optimization models can overcome the high dimensionality of watershed pollution problem. Market based instruments such as permit trading settings which consider abatement measures’ cost heterogeneity have been regarded as being superior to command and control programs. Empirical analysis reveals that when local environmental authority and farmers have different cost information, a permit trading program has the potential to offer cost savings.

The Designation of Co-benefits and Its Implication for Policy: Water Quality versus Carbon Sequestration in Agricultural Soils AgEcon
Secchi, Silvia; Jha, Manoj K.; Kurkalova, Lyubov A.; Feng, Hongli; Gassman, Philip W.; Kling, Catherine L..
This study investigates the implications of treating different environmental benefits as the primary target of policy design. We focus on two scenarios, estimating for both of them in-stream sediment, nutrient loadings, and carbon sequestration. In the first, we assess the impact of a program designed to improve water quality in Iowa on carbon sequestration, and in the second, we calculate the water quality impact of a program aimed at maximizing carbon sequestration. In both cases, the policy instrument is the retirement of land from agricultural production. Our results, limited to the state of Iowa, and to the case of set-aside for water quality or carbon sequestration purposes, indicate that the amount of co-benefits depends on what indicators are used...

Carbon Sequestration in Agriculture: an Offset Program versus Other Conservation Programs AgEcon
Feng, Hongli; Kling, Catherine L..
In this paper, we study the social efficiency of private carbon markets that include trading in agricultural soil carbon sequestration when there are significant co-benefits (positive environmental externalities) associated with the practices that sequester carbon. Likewise, we investigate the efficiency of government run conservation programs that are designed to promote a broad array of environmental attributes (both carbon sequestration and its co-benefits) for the supply of carbon. Finally, policy design and efficiency issues associated with the potential interplay between a private carbon market and a government conservation program are studied. Empirical analyses for an area that represents a significant potential source of carbon sequestration and...

THE SUBSIDY FOR ADOPTING CONSERVATION TILLAGE: ESTIMATION FROM OBSERVED BEHAVIOR AgEcon
Kurkalova, Lyubov A.; Kling, Catherine L.; Zhao, Jinhua.
Due to payoff uncertainties combined with risk aversion and/or real options, farmers may demand a premium in order to adopt conservation tillage practices, over and above the compensation for the expected profit losses (if any). We propose a method of directly estimating the financial incentives for adopting conservation tillage and distinguishing between the expected payoff and the premium of adoption based on observed behavior. We find that the premium may play a significant role in farmers' adoption decisions. Even for non-adopters, conservation tillage provides a higher payoff than does conventional tillage on average, as agronomists have argued. However, non-adopters do not use conservation tillage because the expected profit gain alone does not fully...

LINKING REVEALED AND STATED PREFERENCES TO TEST EXTERNAL VALIDITY AgEcon
Herriges, Joseph A.; Kling, Catherine L.; Azevedo, Christopher D..
This paper examines the potential for combining revealed and stated preference data on Iowa wetland usage, employing a flexible functional form representation of site-specific utility. We examine a variety of hypothesis tests regarding potential sources for inconsistency between stated and revealed preferences, including the form of the state preference questions themselves.

Real Options and the WTP/WTA Disparity AgEcon
Zhao, Jinhua; Kling, Catherine L..
We present a real options model of an agent's decision to purchase or sell a good under conditions of uncertainty, irreversibility, and learning over time. Her WTP and WTA contain both the intrinsic value of the good and an option value associated with delaying the decision until more information is available. Consequently, the standard Hicksian equivalence between WTP/WTA and compen-sating and equivalent variation no longer holds. This helps to explain the WTP/WTA disparity often observed in laboratory experiments and surveys because subjects may have limited learning time and opportunities, thus generating option values. In contrast, the disparity may decrease or disappear entirely in real markets since agents are free to choose when to stop gathering...

ASSESSING THE COSTS AND ENVIRONMENTAL CONSEQUENCES OF AGRICULTURAL LAND USE CHANGES: A SITE-SPECIFIC, POLICY-SCALE MODELING APPROACH AgEcon
Wu, JunJie; Adams, Richard M.; Kling, Catherine L.; Tanaka, Katsuya.
The growth in federal conservation programs has created a need for policy modeling frameworks capable of measuring micro-level behavioral responses and macro-level landscape changes. This paper presents an empirical model that predicts crop choices, crop rotations, and conservation tillage adoption as a function of conservation payment levels, profits, and other variables at more than 42,000 agricultural sites of the National Resource Inventory (NRI) in the Upper Mississippi River Basin. Predicted changes in crop choices and tillage practices are then fed into site-specific environmental production functions to determine changes in nitrate runoff and leaching and in water and wind erosion at each NRI site. This policy-scale model is applied to the case of...

Linking Revealed and Stated Preferences to Test External Validity AgEcon
Herriges, Joseph A.; Kling, Catherine L.; Azevedo, Christopher D..
A new turn in the research agenda of environmental valuation is under way. Rather than treating stated preference (SP) and revealed preference (RP) as competing valuation techniques, analysts have begun to view them as complementary, where the strengths of each approach can be used to provide more precise and possibly more accurate benefit estimates. In this paper, we reexamine the models and motives for combining revealed and stated preference data. First, we note that because the different kinds of SP data contain different amounts of information, they may indicate different degrees of consistency with RP data. We also reconsider the interpretation of "consistent" or "inconsistent" findings of RP and SP data. We argue that while the conventional approach...

THE IMPORTANCE OF FUNCTIONAL FORM IN THE ESTIMATION OF WELFARE AgEcon
Kling, Catherine L..
Researchers have recognized the central role that the choice of functional form has on estimated of consumer surplus. The purpose of this paper is to quantify the magnitude of errors which might arise from the use of incorrect functional forms. It describes a simulation experiment where estimated consumer surplus, based on simulated data sets, is compared with consumer surplus computed directly from the simulate data. The errors resulting from the use of mismatching functional forms range from approximately 4% to 107%.

Optimal Design of Permit Markets with an Ex Ante Pollution Target AgEcon
Rabotyagov, Sergey S.; Feng, Hongli; Kling, Catherine L..
In this paper, we examine the design of permit trading programs when the objective is to minimize the cost of achieving an ex ante pollution target, that is, one that is defined in expectation rather than an ex post deterministic value. We consider two potential sources of uncertainty, the presence of either of which can make our model appropriate: incomplete information on abatement costs and uncertain delivery coefficients. In such a setting, we find three distinct features that depart from the well-established results on permit trading: (1) the regulator's information on firms' abatement costs can matter; (2) the optimal permit cap is not necessarily equal to the ex ante pollution target; and (3) the optimal trading ratio is not necessarily equal to the...

Carbon Sequestration in Agriculture: Value and Implementation AgEcon
Feng, Hongli; Zhao, Jinhua; Kling, Catherine L..
We investigate the value of carbon sequestration in a dynamic model, demonstrating that it is only a fraction of the value of emission abatement unless the sequestration, the natural decay rate of carbon and the discount rate. We also show that to optimally reduce the carbon stock, sinks should be utilized as early as possible. Further, we propose and assess three mechanisms to efficiently introduce sequestration into a carbon permit trading market, a pay-as-you-go system. We show that, although the three mechanisms may not be equally feasible to implement, they are all efficient.

SUBSIDIES! THE OTHER INCENTIVE-BASED INSTRUMENT: THE CASE OF THE CONSERVATION RESERVE PROGRAM AgEcon
Feng, Hongli; Kling, Catherine L.; Kurkalova, Lyubov A.; Secchi, Silvia.
In this paper, we examine command-and-control (CAC) policies and market-based instruments (MBI) in the context of the Conservation Reserve Program (CRP). The CRP, an MBI in the form of subsidies, is by far the largest agro-environmental policy implemented to date. We compare the environmental performance of the CRP as implemented to a few counterfactual CAC polices using EPIC (Environmental Policy Integrated Climate), a bio-physical simulation model. In the context of multiple environmental indicators, no policy alternative emerges as a clear winner. The importance of the choice and design of CAC policies is emphasized.

The Conservation Reserve Program in the Presence of a Working Land Alternative: Implications for Environmental Quality, Program Participation, and Income Transfer AgEcon
Feng, Hongli; Kling, Catherine L.; Kurkalova, Lyubov A.; Secchi, Silvia; Gassman, Philip W..
The United States has invested large sums of resources in multiple conservation programs for agriculture over the past century. In this paper we focus on the impacts of program interactions. Specifically, using an integrated economic and bio-physical modeling framework, we consider the impacts of the presence of working land programs on a land retirement for an important agricultural region—the Upper Mississippi River Basin (UMRB). Compared to a land retirement only program, we find that the presence of a working land program for conservation tillage results in significantly lower predicted signups for land retirement at a given rental rate. We also find that the presence of both a large working land and land retirement program can result in more...

Conservation Payments: Challenges in Design and Implementation AgEcon
Babcock, Bruce A.; Beghin, John C.; Duffy, Michael D.; Feng, Hongli; Hueth, Brent; Kling, Catherine L.; Kurkalova, Lyubov A.; Schneider, Uwe A.; Secchi, Silvia; Weninger, Quinn; Zhao, Jinhua.
As Congress develops new farm legislation, some are lobbying for a new partnership between U.S. taxpayers and farmers. In exchange for an annual transfer of $10 to $20 billion from taxpayers to agriculture, farmers would do much more to enhance environmental quality. An attractive feature of a new partnership is that paying for an improved environment provides a clear and justifiable rationale for farm program payments, something that is lacking under current farm programs. By changing management practices and land use, farmers can provide cleaner water, cleaner air, better wildlife habitat, lower net greenhouse gas emissions, and improved long-run soil quality. Private profit maximizers largely ignore the value of these environmental goods. Hence, the...
