Optimal Placement of Conservation Practices Using Genetic Algorithm with SWAT AgEcon
Jha, Manoj K.; Rabotyagov, Sergey S.; Gassman, Philip W..
The effectiveness of conservation practices depends on their placement on the fields within the watershed. Cost-effective placement of these practices for maximum water quality benefits on each field requires comparing a very large number of possible land-use scenarios. To address this problem, we combine the tools of evolutionary algorithm with the Soil and Water Assessment Tool (SWAT) model and cost data to develop a trade-off frontier of least cost of achieving nutrient reductions and the corresponding locations of conservation practices. This approach was applied to the Raccoon River Watershed, which drains about 9,400 km2 of an intensive agriculture region in west-central Iowa. Applying genetic algorithm to the calibrated SWAT modeling setup produced...

Estimation of a Binary Choice Model with Grouped Choice Data AgEcon
Kurkalova, Lyubov A.; Rabotyagov, Sergey S..
We propose an econometric technique for estimating the parameters of a binary choice model when only aggregated data are available on the choices made. The method performs favorably in applications to both simulated and real world choice data.

Experimental Testbeds for ECOSEL: A Market Framework for Private Provision of Forest Ecosystem Services AgEcon
Toth, Sandor F.; Rabotyagov, Sergey S.; Ettl, Gregory J..
We attempt to design a market framework (which we call ECOSEL) for private provision of forest ecosystem services. ECOSEL is a non-regulatory framework that uses a voluntary public good provision mechanism (in a form of an auction) in conjunction with a multiobjective optimization algorithm to create a market for forest ecosystem services. It is expected to be attractive to the demand side of the ecosystem service market since only Pareto-efficient bundles of services are offered for auction, and it is expected to be attractive to the supply side as well by creating a source of non-timber income for forest landowners. ECOSEL is capable of flexible response to demand for other relevant dimensions of forest-related environmental amenities such as...

ESTIMATION OF A DISCRETE CHOICE MODEL WHEN INDIVIDUAL CHOICES ARE NOT OBSERVABLE AgEcon
Kurkalova, Lyubov A.; Rabotyagov, Sergey S..
This paper presents an econometric technique for circumventing the lack of individual choice data in a framework of binary choice model by utilizing aggregate choice data. The probability of observing a certain number of individuals making choice A out of the total number of individuals in a group is presented as a sum of probabilities of disjoint events, in which some individuals are picked to make choice A, and others are not. These probabilities are then used to form a likelihood function. The model, which is estimated using the method of maximum likelihood, performs favorably in an application to real discrete choice data.

Optimal Design of Permit Markets with an ex ante Pollution Target AgEcon
Rabotyagov, Sergey S.; Feng, Hongli; Kling, Catherine L..
The optimal pollution permit trading system is examined when the regulator, faced with incomplete information on firms' abatement costs and delivery coefficients, seeks to minimize expected total abatement costs to meet an ex ante pollution target. Intuitively, we find that the optimal trading ratio and permit cap are set such that there will be more pollution when abatement costs are high and less pollution when abatement costs are low. Surprisingly however , even when the delivery coefficients are known with certainty, the optimal trading ratio will not necessarily equal the delivery coefficient, nor will it be optimal for the total permit quantity to equal the given pollution target. Instead, the trading ratio will tend to be larger when there is...

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...
