Última Costs, Emissions Reductions, and Vehicle Repair: Evidence from Arizona AgEcon Ando, Amy Whritenour; McConnell, Virginia D.; Harrington, Winston. The Arizona I/M program provides one of the first opportunities to examine the costs and effectiveness of vehicle emission repair. This paper examines various aspects of emission reductions, fuel economy improvements, and costs of repair, drawing data from over 80,000 vehicles failing the I/M test in Arizona between 1995 and the first half of 1996. We summarize the wealth of repair data from the Arizona program and highlight its limitations. Because missing or incomplete cost information has been a serious shortcoming for evaluation of I/M programs, we develop a method for estimating the costs of repair when those costs are not reported. We find surprising evidence that almost one quarter of all vehicles that take the I/M test are never observed to pass...

Ano: 1999 URL: http://purl.umn.edu/10915 The Economic Costs and Benefits of Investments in Municipal Water and Sanitation Infrastructure: A Global Perspective AgEcon Whittington, Dale; Hanemann, W. Michael. This paper presents illustrative estimates of the costs and benefits of investments in municipal water and sanitation systems in developing countries. Four sources of information on the economic benefits households receive from improved municipal water and sanitation services are reviewed: (1) prices charged for vended water, (2) avertive expenditures, (3) avoided costs of illness, and (4) stated preference studies. There is little evidence to suggest that the current monthly benefits of improved water and sanitation services exceed the monthly costs. The most important limitation of such comparisons of annual costs and benefits is that benefits per household may well grow over the life of the investments, but this possibility does not ensure that such...

China’s emerging standing in the world demands a major rethinking of its diplomatic strategies. Given its population size, geographical scale, economic power and military presence, China is poised to play a larger political role in the twenty-first century, and is thus perceived by the international community to have greater capacities, capabilities and responsibilities. At the same time, environmental stresses caused by China’s energy and resources demands have become increasingly evident in recent years, urging China to cultivate delicate diplomatic relations with its neighbors and strategic partners. Tensions have been seen in areas such as transboundary air pollution, cross-border water resources management and resources exploitation, and more recently...

METHODOLOGICAL PROPOSAL AND FIRST APPLICATIONS IN APULIA REGION (SOUTHERN ITALY) AgEcon Scardigno, Alessandra; Bazzani, Guido Maria. The implementation of most recent CAP and water policy reforms calls for simulation analytical tools able to quantify socio-economic and environmental impacts that can be different in terms of regions and farm type. This work proposes a territorial mathematical programming model that integrates hundreds of farm models clustered in a single meta-model at regional level that can be easily standardized having the FADN as the main data source. The tool has been experimentally applied to Apulia region and several simulations have been conducted in scenarios differing in terms of agricultural policies (total decoupling, increase of the modulation rate and introduction of a flat rate system for the Single Farm Payment), price of the water resource, market...

Ano: 2008 URL: http://purl.umn.edu/44799 Structure and bargaining power in multilateral negotiations: Application to water management policies in France AgEcon Simon, Leo K.; Thoyer, Sophie; Morardet, Sylvie; Goodhue, Rachael E.; Rio, Patrick; Rausser, Gordon C.. Environmental policies are characterized by a growing emphasis on participation, devolution and negotiated decision making. Increasingly, centralized top down decision making systems are being replaced by new forms of local governance. In their strongest versions, these involve delegation of formal authority to local stakeholders who are expected to decide collectively upon the management rules of local common-pool resources. Devolution is particularly important in relation to the allocation and management of scarce water resources. Indeed the French water law of 1992 institutionalised the notion of devolution by requiring that water management rules be negotiated at the river basin level between all stakeholders. Although stakeholder negotiation is... Tipo: Conference Paper or Presentation Palavras-chave: Environmental Economics and Policy; Resource /Energy Economics and Policy; C78; Q25; D78. Ano: 2003 URL: http://purl.umn.edu/58258 The Dissemination of Private Wells and Double Tragedies: The Overexploitation of Groundwater among Well Users and Increased Poverty among Non-Well Users in Tamil Nadu, India AgEcon Kajisa, Kei; Palanisami, Kuppannan; Sakurai, Takeshi. This paper investigates the impact of the dissemination of modern irrigation systems, i.e. private wells with pumps, on the livelihood not only among the farmers who have access to wells but also among the farmers who have no access to wells and thus rely solely on traditional irrigation systems called tank irrigation systems. The analysis is based on a village and household data set collected in Tamil Nadu, India where tank irrigation systems have been managed collectively for rice cultivation. Our statistical analyses predict that once declines in collective management occur due to the dissemination of private wells, the rice yield and income of the no-well-access farmers alone will decrease, resulting in increased poverty among them. Our analyses also... Tipo: Conference Paper or Presentation Palavras-chave: Irrigation; Well; Common property; Poverty; India; Resource /Energy Economics and Policy; O3; O13; Q25.

A voluntary stormwater management program that is incentive compatible between residential developers and regulators produces an outcome that simultaneously protects/enhances water quality and increases developer profits. Developers pay a participation fee and the collected fees are used to retrofit ineffective stormwater management systems in older neighborhoods to improve water quality.

Ano: 2010 URL: http://purl.umn.edu/56541 Consolidation as a Regulatory Compliance Strategy: Small Drinking Water Systems and the Safe Drinking Water Act AgEcon Lee, Min-Yang A.; Braden, John B.. Despite extensive research and policy initiatives to increase the technical, financial, and managerial capacity of small drinking water systems, there has been little research focusing on understanding how consolidation can increase the overall capacity of the drinking water industry. Consolidation of water systems may be a mechanism that increases regulatory compliance by removing poorly performing systems from the industry and replacing inefficient management and/or capital. The US drinking water system is highly fragmented, with over 50,000 Community Water Systems (CWSs), of which the vast majority are classified as "small" by the US Environmental Protection Agency (EPA).

Ano: 2007 URL: http://purl.umn.edu/9772 Hyperbolic discounting in analyzing investment in groundwater irrigation in India AgEcon Chandrakanth, Mysore G.; Rashmi, N.; Chandrashekar, H.; Nagaraj, N.. Researchers are often confronted with the choice of discount rate as well as the method of discounting for estimating the amortized cost of long-term investment in agriculture including groundwater irrigation. The obvious choice is to use the opportunity cost of capital, which is the prevailing interest rate of around 9 percent (compounded – exponential basis), charged on longterm agriculture loans. However, using the ‘exponential’ basis does not provide a realistic amortized cost of irrigation as it over estimates the value of investment due to ‘exponential’ basis as demonstrated above. In order to obtain an empirical estimate of this interest rate, using field data from farmers three dry agro-climatic zones of Karnataka (Shamsundar (1996), Sripadmini...

Ano: 2006 URL: http://purl.umn.edu/43626 Optimal Management of a Potential Invader: The Case of Zebra Mussels in Florida AgEcon Lee, Donna J.; Adams, Damian C.; Rossi, Frederick J.. Dominant users of Lake Okeechobee water resources are agricultural producers and recreational anglers. These uses will be directly affected, should the lake become infested with zebra mussels. We employ a probabilistic bioeconomic simulation model to estimate the potential impact of zebra mussels on consumptive water uses, recreational angling, and wetland ecosystem services under alternative public management scenarios. Without public management, the expected net economic impact from zebra mussels is - $244.1 million over 20 years. Public investment in prevention and eradication will yield a net expected gain of +$188.7 million, a superior strategy to either prevention or eradication alone.

Ano: 2007 URL: http://purl.umn.edu/37125 Policy Instruments for Climate Change: How Can National Governments Address a Global Problem? AgEcon Stavins, Robert N.. There continues to be great debate about the desirability of taking actions to limit carbon dioxide (CO2) and other greenhouse gas emissions, but it is important to consider policy instruments that can be employed to meet targets that may eventually be forthcoming. The theoretical advantages of market-based instruments, such as carbon taxes and systems of tradable carbon rights, are striking. In the U.S. domestic context, grandfathered tradable permits will probably be the preferred approach (if any) in the short run, although revenueneutral carbon taxes will hold greater promise in the long run. In the international context, a system of international tradable permits could provide important advantages over alternative approaches, but it is difficult to...

Ano: 1997 URL: http://purl.umn.edu/10757 Water communities in the Republic of Macedonia: an empirical analysis of membership satisfaction and payment behaviour AgEcon Gorton, Matthew; Sauer, Johannes; Peshevski, Mile; Bosev, Dane; Shekerinov, Darko; Quarrie, Steve. Utilizing primary survey data, we investigate the performance of Water Communities (WCs), a form of self-managing organisation for irrigation, in the Bregalnica region of the Republic of Macedonia. While their introduction improved cost recovery, only modest changes occurred in the cost of irrigation water and many farmers remain indifferent to the WCs. Econometric analysis focuses on the decision of farmers to join a WC, determinants of farmers’ satisfaction with WCs and factors associated with changes in payment behaviour. Key determinants identified include transparency and trust regarding the conduct of WCs, cost recovery rates, farm size and irrigation costs. Membership satisfaction is an important determinant of payment behaviour.

Ano: 2009 URL: http://purl.umn.edu/51030 Comparing choice models of river health improvement for the Goulburn River AgEcon Kragt, Marit Ellen; Bennett, Jeffrey W.; Lloyd, Chris; Dumsday, Robert G.. The extent of the benefits of improved river health remain uncertain. Quantifying these benefits is useful in prioritising policy investments. This study uses the Choice Modelling technique to estimate the value that households attach to attributes of improved river health. Data from a choice modelling survey supported by DSE Victoria are employed to elicit household preferences in a case study of the Goulburn River. Results from conditional and nested logit model specifications indicate that respondents hold positive values for higher levels of fish and bird populations and for increasing riverside vegetation. The standard Hausman test for Independence-from-Irrelevant-Alternatives (IIA) assumptions violations is found to give inconsistent results. The...

Ano: 2007 URL: http://purl.umn.edu/10359 Baseline Determination at Government Discretion: Multi-Project Baselines for the First Track of Joint Implementation? AgEcon Michaelowa, Axel; Schmitz, Simon. The "first track" of Joint Implementation under the Kyoto Protocol gives host and investor countries total freedom in choosing a baseline for a project reducing or sequestering greenhouse gases. This is due to the fact that an overly generous granting of emission credits leads to a corresponding reduction of the host country's emission budget. Standardised, multi-project baselines can reduce transaction costs, especially in relatively homogeneous sectors such as electricity production or landfill methane collection. Host countries need capacity to calculate such baselines which currently does not exist. "Boundary organisations" can bridge the gap between technical analysis and strategic considerations. Interviews with government officials and other...

Ano: 2003 URL: http://purl.umn.edu/26173 Role of Watershed Management in Bridging Demand – Supply Gap of Fodder for Enhancing Livestock Production in Shivaliks, Haryana AgEcon Arya, Swarn Lata; Panwar, Pankaj; Yadav, R.P. Watershed programme is an important intervention in dryland areas to improve livestock productivity through increased feed and fodder supply. The present study has focused on the impact of watershed interventions on crop-livestock linkages with particular emphasis on how the interventions have affected the quantity of stovers/straws as livestock feeding materials in bridging the demand-supply gap. The study has been carried out in three typical Shivalik foothill watersheds (two treated and one untreated) in the Panchkula district of Haryana state. The impact of watershed development programme has been estimated by adopting both with and without approach and before and after approach. The untreated watershed has derived 65 per cent of its total income from...

Ano: 2011 URL: http://purl.umn.edu/118230 The Effect of Sequencing Trade and Water Market Reform on Interest Groups in Irrigated Agriculture: An Intertemporal Economy-Wide Analysis of the Moroccan Case AgEcon Diao, Xinshen; Roe, Terry L.. Many of the import competing sectors in Moroccan agriculture are protected while water in irrigated agriculture is priced below its marginal value product. Establishing a water market in this pre-trade reform environment can be welfare decreasing. Further, as the shadow price of water is sensitive to the crops protected by trade policy, farmers growing crops protected pre-trade reform can be made worse off post reform. The resulting decline in rents to sector resources is a source of interest group conflict that can slow the overall reform process. Using an intertemporal general equilibrium model, the paper analyzes the economy-wide effects of the linkages between trade reform and the reform of water markets in irrigated agriculture. We find a strong... Tipo: Working or Discussion Paper Palavras-chave: Water Markets; Trade Reform.

Implications for Climate Policy AgEcon Carraro, Carlo; De Cian, Enrica; Nicita, Lea. Climate-economy models aiming at quantifying the costs and effects of climate change impacts and policies have become important tools for climate policy decision-making. Although there are several important dimensions along which models differ, this paper focuses on a key component of climate change economics and policy, namely technical change. This paper tackles the issues of whether technical change is biased towards the energy sectors, the importance of the elasticity of substitution between factors in determining this bias and how mitigation policy is likely to affect it. The analysis is performed using the World Induced Technical Change model, WITCH. Three different versions of the model are proposed. The starting set-up includes endogenous technical...

This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects the net revenues of farms across Africa. Applying these results to possible future climates reveals that dryland farms are especially climate sensitive. Even as early as 2020, climate change could have strong negative impacts on currently dry and hot locations. By 2100, dryland crop net revenues could rise by 51% if future warming is mild and wet but fall by 43% if future climates are hot and dry. The crop net revenues of currently irrigated farms are likely to be...
