A Binary Logit Estimation of Factors Affecting Adoption of GPS Guidance Systems by Cotton Producers AgEcon
Banerjee, Swagata (Ban); Martin, Steven W.; Roberts, Roland K.; Larkin, Sherry L.; Larson, James A.; Paxton, Kenneth W.; English, Burton C.; Marra, Michele C.; Reeves, Jeanne M..
Binary logit analysis was used to identify the factors influencing adoption of Global Positioning System (GPS) guidance systems by cotton farmers in 11 Mid-south and Southeastern states. Results indicate that adoption was more likely by those who had already adopted other precision-farming practices and had used computers for farm management. In addition, younger and more affluent farmers were more likely to adopt. Farmers with larger farms and with relatively high yields were also more likely to adopt. Education was not a significant factor in a farmer’s decision to adopt GPS guidance systems.

A META-ANALYSIS OF ENVIRONMENTAL KUZNETS CURVE STUDIES AgEcon
Cavlovic, Therese A.; Baker, Kenneth H.; Berrens, Robert P.; Gawande, Kishore.
An understanding of the empirical relationship between income and environmental quality is evolving through recent studies investigating the Environmental Kuznets Curve (EKC). The EKC represents an inverted-U relationship between income and environmental degradation. However, studies may employ different methods, evaluate different environmental indicators, and use different data, resulting in a broad spectrum of findings and leading to sometimes conflicting interpretations. The purpose of this paper is to synthesize the results of existing EKC findings by conducting a statistical meta-analysis, and to predict new income turning points (ITP). Results indicate how both methodological choices and pollutant types affect ITPs.

A RENEWAL THEORETIC APPROACH TO ENVIRONMENTAL STANDARD SETTING AgEcon
Batabyal, Amitrajeet A..
The process of environmental regulation is usually a two-step one. In the first step, a standard for environmental quality is set. Then, in the second step, a regulatory mechanism is put in place to achieve the standard. In this paper I show how renewal theory can be used to set the quality standard optimally.

A Social Scientist's Perspective on the Potential Benefits of the Census of Marine Life AgEcon
Sanchirico, James N..
Over 300 natural scientists in 53 nations are taking part in the Census of Marine Life (CoML) to investigate what lived, what lives, and what will live in the oceans. The CoML is a scientific experiment that is exploring the limits of ocean science. The paper discusses the potential applications of CoML research and the mechanisms by which the potential benefits can be measured and preserved. I recommend developing and integrating policy advisory committees with the natural science activities to both maximize the benefits of the research and to avoid unintended consequences.

Accumulative Pollution, "Clean Technology," and Policy Design AgEcon
Withagen, Cees; Toman, Michael.
Environmental policymakers must address the adverse effects of a number of pollutants that accumulate in the environment. Goals for the regulation of these damages often involve holding long-term emissions below a level deemed to be "dangerous", or outright banning of offending products or processes along with subsidization of more "green" alternatives. This paper builds upon previous studies by Keeler, Spence, and Zeckhauser (1971) and Tahvonen and Withagen (1996) in addressing the optimal long-term management of an accumulative but assimilatable pollutant through policies that restrict more damaging production processes and thereby induce more benign alternatives. Using a simple general equilibrium approach, we consider the possibility that the...

Age, Health, and the Willingness to Pay for Mortality Risk Reductions: A Contingent Valuation Survey of Ontario Residents AgEcon
Krupnick, Alan J.; Alberini, Anna; Cropper, Maureen L.; Simon, Nathalie B.; O'Brien, Bernie; Goeree, Ron; Heintzelman, Martin.
Much of the justification for environmental rulemaking rests on estimates of the benefits to society of reduced mortality rates. This research aims to fill gaps in the literature that estimates the value of a statistical life (VSL) by designing and implementing a contingent valuation study for persons 40 to 75 years of age, and eliciting WTP for reductions in current and future risks of death. Targeting this age range also allows us to examine the impact of age on WTP and, by asking respondents to complete a detailed health questionnaire, to examine the impact of health status on WTP. This survey was self-administered by computer to 930 persons in Hamilton, Ontario, in 1999. The survey uses audio and visual aids to communicate baseline risks of death and...

Alternative Approaches for Moderating Food Insecurity and Price Volatility in Zambia. AgEcon
Dorosh, Paul A.; Dradri, Simon; Haggblade, Steven.
• Maize production varies widely from year to year, given Zambia’s heavy dependence on rainfed cultivation. Thus consumers face wide swings in availability of their primary food staple. • Typical public responses include increased food aid inflows, government commercial imports and stock releases, and tight controls on private sector trade. While intended to improve domestic supply, these public responses can inadvertently exacerbate price instability and food insecurity for Zambian consumers. • Two key private sector responses – private cross-border maize trade and consumer substitution of alternate food staples (such as cassava) for maize - can also help to moderate food consumption volatility. • Together, private imports and increased cassava...

AN AGENDA FOR THE STUDY OF LAND USE, WILDERNESS DESIGNATION, AND RESOURCE REGULATION IN THE AMERICAN WEST AgEcon
Batabyal, Amitrajeet A..
Atemporal and intertemporal use of public lands, the determination of optimal levels of wilderness designation and habitat preservation, and the appropriate regulation of natural resources have all been "hot button" issues in the American West for quite some time now. In this paper, I propose and describe a research agenda which promises to yield interesting and useful new policy insights into these fractious resource issues.

ARE ECO-LABELS VALUABLE? EVIDENCE FROM THE APPAREL INDUSTRY AgEcon
Nimon, R. Wesley; Beghin, John C..
Using U.S. apparel catalogue data, we estimate hedonic price functions to identify market valuation of environmental attributes of apparel goods. We identify a significant and robust premium for the organic fibers embodied in the apparel goods. We find an additional organic premium for baby items. However, we do not find evidence of a premium for environment-friendly dyes. We further investigate the pricing behavior of apparel suppliers for potential departure from competitive pricing of this environmental attribute and find no evidence different premium across firms, suggesting price-taking behavior in the environmental attribute space.

Are Eco-Labels Valuable? Evidence from the Apparel Industry AgEcon
Nimon, R. Wesley; Beghin, John C..
Using U.S. apparel catalogue data, we estimate hedonic price functions to identify market valuation of environmental attributes of apparel goods. We identify a significant and robust premium for the organic fibers embodied in the apparel goods. We also find a discount for the "no-dye" label. We do not, however, find any evidence of a premium for environment-friendly dyes. We further investigate the pricing behavior of apparel suppliers for potential heterogenous pricing of the organic-fiber attribute and find no evidence of different premia across firms.

Assessing Sustainability: Some Conceptual and Empirical Challenges AgEcon
Toman, Michael; Lile, Ronald D.; King, Dennis M..
In this paper we address two related conceptual and practical challenges in assessing "sustainability." The first is the criteria to be used, in particular the relationship between sustainability and measures of economic well-being and the use of monetary versus nonmonetary indicators. The second is the problem of determining which physical scales to use for sustainability assessments when there are multiple and overlapping "communities" or stakeholder groups. While neither set of challenges admits a definitive solution, there has been progress on the first set of issues - in particular, through the development of multicriteria assessment strategies and stakeholder involvement processes. In contrast, the problem of how to assess sustainability in practice...

Benefit Transfer as Preference Calibration AgEcon
Smith, V. Kerry; van Houtven, George; Pattanayak, Subhrendu K..
This paper proposes and illustrates the use of a new approach to benefit transfer for the non-market valuation of environmental resources. It treats transfer as an identification problem that requires assessing whether available benefit estimates permit the parameters of a preference function to be identified. The transfer method proposed uses these identifying restrictions to calibrate preference parameters and bases the benefit estimates on that preference function. The approach is illustrated using travel cost, hedonic and contingent valuation estimates, as well as combinations of estimates. It has three potential advantages over conventional practice: (1) it allows multiple, potentially overlapping estimates of the benefits of an improvement in...

Bioeconomic Model of Community Incentives for Wildlife Management Before and After CAMPFIRE AgEcon
Fischer, Carolyn; Muchapondwa, Edwin; Sterner, Thomas.
This paper formulates a bioeconomic model to analyze community incentives for wildlife management under benefit-sharing programs like the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) in Zimbabwe. Two agents influence the wildlife stock: a parks agency determines hunting quotas, and a local community chooses to either aid or discourage outside poachers. Wildlife generates revenues from hunting licenses and tourism; it also intrudes on local agriculture. We consider two benefit-sharing regimes: shares of wildlife tourism rents and shares of hunting licenses. Resource sharing does not necessarily improve community welfare or incentives for wildlife conservation. Results depend on the exact design of the benefit shares, the size of...

Calculating the Costs of Environmental Regulation AgEcon
Pizer, William A.; Kopp, Raymond J..
Decisions concerning environmental protection hinge on estimates of economic burden. Over the past 30 years, economists have developed and applied various tools to measure this burden. In this paper, developed as a chapter for the Handbook of Environmental Economics, we present a taxonomy of costs along with methods for measuring those costs. At the broadest level, we distinguish between partial and general equilibrium costs. Partial equilibrium costs represent the burden directly borne by the regulated entity (firms, households, government), including both pecuniary and nonpecuniary expenses, when prices are held constant. General equilibrium costs reflect the net burden once all good and factor markets have equilibrated. In addition to partial...

Causes of Diversification in Agriculture Over Time: Evidence From Norwegian Farming Sector AgEcon
Culas, Richard J.; Mahendrarajah, Mahen.
Farm planning generally focuses on optimal diversification with respect to risk and uncertainties, where the risk-management strategies combine production, marketing, financial and environmental responses of the production of farm firm. In this study an empirical examination of farm diversification has been carried out from a sample of farms in Eastern Norway in which four measures of diversification (indices) were defined to incorporate the risk and uncertainties in relation to farm production (total) income. Using these four alternative measures of diversification and panel-data techniques, it has been shown that larger farms are more diversified, and when there is productive location and access to labour the farmers have a greater incentive to spread...

Challenges and Opportunities for Water of the Rio Grande AgEcon
Rister, M. Edward; Sturdivant, Allen W.; Lacewell, Ronald D.; Michelsen, Ari M..
The Rio Grande has headwaters in Colorado, flows through New Mexico, and serves as the United States.–Mexico border in Texas, emptying into the Gulf of Mexico. Snow melt in Colorado and northern New Mexico constitutes the water river supply for New Mexico and the El Paso region, whereas summer monsoonal flow from the Rio Conchos in Mexico and tributaries, including the Pecos River, provides the Rio Grande flow for southern Texas. The region is mostly semiarid with frequent long-term drought periods but is also characterized by a substantial irrigated agriculture sector and a rapidly growing population. International treaties and interstate compacts provide the rules for allocation of Rio Grande waters between the United States and Mexico and among...

Comparing the Effectiveness of Regulation and Pro-Social Emotions to Enhance Cooperation: Experimental Evidence from Fishing Communities in Colombia AgEcon
Lopez, Maria Claudia; Murphy, James J.; Spraggon, John M.; Stranlund, John K..
This paper presents the results from a series of framed field experiments conducted in fishing communities off the Caribbean coast of Colombia. The goal is to investigate the relative effectiveness of exogenous regulatory pressure and pro-social emotions in promoting cooperative behavior in a public goods context. The random public revelation of an individual’s contribution and its consequences for the rest of the group leads to significantly higher public good contributions and social welfare than regulatory pressure, even under regulations that are designed to motivate fully efficient contributions.

Conservation Auctions in Manitoba: A Summary of a Series of Workshops AgEcon
Packman, Katherine; Boxall, Peter C..
Currently, the effect of human impact on the environment is becoming increasingly apparent. The encroachment of human activity has inevitably resulted in the loss or impairment of ecological goods and services (EG&S) around the globe as well as in our own backyard. EG&S include features such as wildlife habitat, biodiversity, soil renewal, or nutrient cycling. The loss of such features has become a sobering reality for Manitobans in the face of the utrophication of Lake Winnipeg as a result of practices contributing to nutrient loading into the lake. Since EG&S are very important to Manitobans, efforts are being made to explore different vehicles to encourage their provision. In order to address some of the environmental issues transpiring in...
