A Coasian Approach to Efficient Water Allocation of a Transboundary River AgEcon
Willis, David B.; Baker, Justin Scott.
The United States and Mexico recently resolved a decade-old water dispute that required Mexico to repay the accumulated water debt within one year. A Coasian analysis estimates the social welfare gains attainable to each country under an alternative debt repayment scheme that allows repayment over a longer time horizon and in a combination of dollars and water, instead of solely in water. Assuming average water supply conditions, under the agreed 1-year repayment contract, U.S. compensation value is 534% greater and Mexico’s compensation cost is 60% less relative to when compensation is paid exclusively in water.

Aquifer Depletion and the Cost of Water Conservation: The Southern High Plains of Texas Case AgEcon
Wheeler, Erin A.; Segarra, Eduardo; Johnson, Phillip N.; Willis, David B.; Johnson, Jeffrey W..
Irrigated agriculture has played a vital role in the development and growth of the Great Plains Region of the United States. The primary source of water for irrigation in this region is the Ogallala Aquifer. The Southern portion of the Ogallala Aquifer is considered exhaustible due to the low level of recharge relative to the quantities of water pumped. Analysis and evaluation of water conservation policies which could extend the economic life of the Ogallala Aquifer in the Southern High Plains of Texas and Eastern New Mexico, and which could contribute to maintaining the viability of the regional economy is important. This study evaluates the impacts of water conservation policies which limit drawdown of the Ogallala Aquifer. County level dynamic...

Assessing Domestic Demand for Organic and ‘Locally Grown' Produce on An ‘Organic Island': Dominica's Dilemma AgEcon
Boys, Kathryn A.; Willis, David B.; George, Seraphine; Hammig, Michael D..
The economy of Dominica faces a unique set of challenges. As with many other Caribbean nations, Dominica has historically been dependent upon agriculture. Over the past several hundred years, the island's economy has been largely supported through the concentrated mono-cropping of a variety of export-oriented crops including coffee, limes, vanilla, and bananas (FAVACA, 2008). Today, approximately 45% of Dominica's labor force is employed in the agricultural sector (FAVACA, 2008). While neighboring countries have economically benefited from tourism, due to its lack of white sand beaches, Dominica is not a typical tourist destination. Taking advantage of its landscape, rainforests, and diversity of natural wildlife, in an effort to diversify its economy...

Discussion: Water Scarcity–Future Uses and Implications for Policy AgEcon
Willis, David B..
The three articles presented at this invited session examine the evolution of water policy planning and the implementation of regulatory tools to achieve water conservation objectives. Two articles focus on Texas water issues and the third focuses on the Georgia planning experience. Each article clearly illustrates the value of sharing advances in hydrologic and economic modeling with local community stakeholder groups to facilitate the credible development of regional water management plans. Moreover, each article hints that stronger regulatory tools may be needed to achieve long-run policy objectives.

Effectiveness of Two Water Conservation Policies: An Integrated Modeling Approach AgEcon
Das, Biswa R.; Willis, David B.; Johnson, Jeffrey W..
Agriculture in the Texas High Plains depends entirely on the Ogallala Aquifer. Texas enacted water conservation legislation to address declining reserves in the aquifer. We developed an integrated regional water policy model that links a hydrology model with an economic optimization model to estimate policy impacts with respect to economic cost and water conservation. Testing the effectiveness of two policies, a groundwater extraction tax and extraction quotas, we observe that neither significantly inhibits groundwater use. Although both policies conserve similar amounts of groundwater, the regional cost of the tax policy to agriculture is more than the quota policy.

IRRIGATION EFFICIENCY, WATER STORAGE, AND LONG RUN WATER CONSERVATION AgEcon
Hamilton, Joel R.; Willis, David B..
A spreadsheet-based simulation model is used to illustrate the complex relationships between irrigation efficiency, water banking and water conservation under the prior appropriation doctrine. Increases in irrigation efficiency and/or establishment of water banks do not guarantee water conservation. Conservation requires reduction in the quantity of water consumptively used by agriculture.

Policy Alternatives for the Southern Ogallala Aquifer AgEcon
Wheeler, Erin A.; Segarra, Eduardo; Johnson, Phillip N.; Johnson, Jeffrey W.; Willis, David B..
Due to declining water levels in the Ogallala Aquifer, policy alternatives for extending the life of the aquifer for irrigation and other purposes are evaluated. The study concludes that blanket water conservation policies for the region are likely to be inefficient because of economic and hydrologic differences in the region.

Price Endogeneity and Marginal Cost Effects on Incentive Compatible Stormwater Management Policies AgEcon
Huber, Matthew C.; Willis, David B.; Hayes, John C.; Privette, Charles V., III.
Incentive based stormwater management policies offer the prospect of reducing urban stormwater runoff while increasing developer profits. An incentive compatible Stormwater Banking Program (SBP) is presented that allows developers to build at higher residential densities in exchange for including low impact stormwater Best Management Practices (BMPs) in the development’s stormwater management infrastructure. Price endogeneity presents itself when the smaller residential lots created by building at a greater density sell for a lower price than the original, larger lots. Stormwater management authorities must be aware of this and the effects of the program participation fee structure in designing voluntary incentive based policies that meet runoff reduction...

The Determinants of Self-Employed Income in a Regional Economy AgEcon
Swindall, Devin C.; Willis, David B.; Boys, Kathryn A.; Hughes, David W..
Supporters claim that entrepreneurship is critical to building and sustaining the regional economies of urban and rural areas across the nation. Proponents argue that economic development practices that enhance and support entrepreneurship are essential because they cultivate innovation which, in turn, creates new jobs, new wealth, and a better quality of life. However, South Carolina’s real self-employed per capita income has decreased over the last decade. This downward trend highlights the need to examine the drivers of entrepreneurial income. The income of self-employed workers, as opposed to the number of self-employed, is critical to economic development because a major goal of economic policy is to increase incomes not just employment. Identifying...

The Economic Value of Basin Protection to Improve the Quality and Reliability of Potable Water Supply: Some Evidence from Ecuador AgEcon
Zapata, Samuel D.; Benavides, Holger M.; Carpio, Carlos E.; Willis, David B..
This study estimates the willingness to pay (WTP) of Loja’s households to protect two micro-basins that supply over 40 percent of potable water to the city. Results indicate that households have an average WTP of $5.80 per month, which corresponds to a 25 percent increase in the self-reported monthly water bill, to preserve the basins.

The Effect of Label Information on Farmers’ Pesticide Choice AgEcon
Hasing, Tomas; Carpio, Carlos E.; Willis, David B.; Sydorovych, Olha; Marra, Michele C..
The general objective of this study was to analyze the effect of labeling information on farmers’ herbicide choice. Herbicide choices made by farmers were used to estimate their willingness to pay for different herbicide attributes. Estimation results indicate that human health and environmental statements displayed on pesticide labels (which reflect higher level of risk) are important components in herbicide selection. For example, it is estimated that farmers are willing to pay, on average, $27 per acre to avoid using an herbicide with the word “Warning” and $38 per acre to avoid using an herbicide with the word “Danger.”

THE EFFECT OF STOCHASTIC IRRIGATION DEMANDS AND SURFACE WATER SUPPLIES ON ON-FARM WATER MANAGEMENT AgEcon
Willis, David B.; Whittlesey, Norman K..
This study presents a procedure for simultaneously addressing stochastic input demands and resource supplies for irrigated agriculture within a linear modeling framework. Specifically, the effect of stochastic crop net irrigation requirements and streamflow supplies on irrigation water management is examined. Irrigators pay a self-protection cost, in terms of water management decisions, to increase the probability that stochastic crop water demand is satisfied and anticipated water supply is available. Self-protection cost is lower when increasing the probability that anticipated water supplies are delivered, ceteris paribus, than when increasing the probability that the crop receives full net irrigation requirement in the study region.

THE EFFECTS OF WATER RIGHTS AND IRRIGATION TECHNOLOGY ON STREAMFLOW AUGMENTATION COST IN THE SNAKE RIVER BASIN AgEcon
Willis, David B.; Caldas, Jose Vaz; Frasier, W. Marshall; Wittlesey, Norman K.; Hamilton, Joel R..
Three species of salmon in the Snake River Basin have been listed as endangered. Recovery efforts for these fish include attempts to obtain increased quantities of water during smolt migration periods to improve habitat in the lower basin. Agriculture is the dominant user of surface flows in this region. This study investigates farmer cost of a contingent water contract requiring the agricultural release of stored irrigation supplies in low flow years during critical flow periods. Results show that contingent contracts can provide substantial quantities of water at a relatively modest cost without significantly affecting the agricultural base of the area.

The Impact of Spatial Heterogeneity in Land Use Practices and Aquifer Characteristics on Groundwater Conservation Policy Cost AgEcon
Willis, David B.; Stovall, Jeff; Johnson, Jeffrey W.; Rainwater, Ken; Barbato, Lucia S.; Mulligan, Kevin; Fish, Ernest B..
Estimation of agricultural policy cost for a given level of groundwater conservation requires the establishment of an accurate baseline condition. This is especially critical when the benefits and cost of any conservation program are generally estimated relative to the status quo policy or baseline situation. An inaccurate baseline estimate will lead to poor estimates of potential water conservation savings and agricultural policy cost. Over a 60-year planning horizon per acre net present value is as much as 29.8% higher for a study area when aquifer characteristics are assumed to be homogenous and set to their average area value than when the heterogeneity in aquifer characteristics is explicitly modeled.
