A cost-effectiveness analysis of two different antimicrobial stewardship programs BJID
Okumura,Lucas Miyake; Riveros,Bruno Salgado; Gomes-da-Silva,Monica Maria; Veroneze,Izelandia.
Abstract There is a lack of formal economic analysis to assess the efficiency of antimicrobial stewardship programs. Herein, we conducted a cost-effectiveness study to assess two different strategies of Antimicrobial Stewardship Programs. A 30-day Markov model was developed to analyze how cost-effective was a Bundled Antimicrobial Stewardship implemented in a university hospital in Brazil. Clinical data derived from a historical cohort that compared two different strategies of antimicrobial stewardship programs and had 30-day mortality as main outcome. Selected costs included: workload, cost of defined daily doses, length of stay, laboratory and imaging resources used to diagnose infections. Data were analyzed by deterministic and probabilistic sensitivity...

Cost-utility of quadrivalent versus trivalent influenza vaccine in Brazil – comparison of outcomes from different static model types BJID
Van Bellinghen,Laure-Anne; Marijam,Alen; de Araujo,Gabriela Tannus Branco; Gomez,Jorge; Van Vlaenderen,Ilse.
ABSTRACT Background: Influenza burden in Brazil is considerable with 4.2–6.4 million cases in 2008 and influenza-like-illness responsible for 16.9% of hospitalizations. Cost-effectiveness of influenza vaccination may be assessed by different types of models, with limitations due to data availability, assumptions, and modelling approach. Objective: To understand the impact of model complexity, the cost-utility of quadrivalent versus trivalent influenza vaccines in Brazil was estimated using three distinct models: a 1-year decision tree population model with three age groups (FLOU); a more detailed 1-year population model with five age groups (FLORA); and a more complex lifetime multi-cohort Markov model with nine age groups (FLORENCE). Methods: Analysis...

Efficient Conservation in a Utility-Maximization Framework Ecology and Society
Davis, Frank W; University of California; fd@bren.ucsb.edu; Costello, Christopher; University of California; costello@bren.ucsb.edu; Stoms, David; University of California; stoms@bren.ucsb.edu.
Systematic planning for biodiversity conservation is being conducted at scales ranging from global to national to regional. The prevailing planning paradigm is to identify the minimum land allocations needed to reach specified conservation targets or maximize the amount of conservation accomplished under an area or budget constraint. We propose a more general formulation for setting conservation priorities that involves goal setting, assessing the current conservation system, developing a scenario of future biodiversity given the current conservation system, and allocating available conservation funds to alter that scenario so as to maximize future biodiversity. Under this new formulation for setting conservation priorities, the value of a site depends on...

Tackling the motivation to monitor: success and sustainability of a participatory monitoring program Ecology and Society
Singh, Navinder J.; Swedish University of Agricultural Sciences; navinder.singh@slu.se; Danell, Kjell; ; kjell.danell@slu.se; Edenius, Lars; ; lars.edenius@slu.se.
Monitoring of species and their ecosystem attributes is a fundamental requirement in applied ecology and conservation. However, landscape scale monitoring requires an immense effort and commitment, especially when species have a wide distribution or are migratory in nature. Participatory monitoring, whereby local communities are engaged, is increasingly being proposed to address landscape scale monitoring. Its implementation is met with many challenges related to finances, motivation of the local people, lack of trained manpower, and nondirect legal use of the species in question. It is of interest to determine what makes a participatory monitoring program interesting for locals to ensure their long term engagement. Using the unique 26-year program of...

A decision-making framework to reduce the risk of collisions between ships and whales ArchiMer
Sèbe, Maxime; Kontovas, Christos, A.; Pendleton, Linwood.
Ship strikes are one of the main human-induced threats to whale survival. A variety of measures have been used or proposed to reduce collisions and subsequent mortality of whales. These include operational measures, such as mandatory speed reduction, or technical ones, such as detection tools. There is, however, a lack of a systematic approach to assessing the various measures that can mitigate the risk of ship collisions with whales. In this paper, a holistic approach is proposed to evaluate mitigation measures based on a risk assessment framework that has been adopted by the International Maritime Organization (IMO), namely the Formal Safety Assessment (FSA). Formal Safety Assessment (FSA) is “a rational and systematic process for assessing the risk...

Sequential process to choose efficient sampling design based on partial prior information data and simulations ArchiMer
Kermorvant, Claire; Coube, Sébastien; D’amico, Frank; Bru, Noëlle; Caill-milly, Nathalie.
Issues on sampling procedure definition led numerous study results to be biased and object of controversy. Choosing relevant sampling design and number of samples is a difficult task when wanted to set up or optimize a survey. The survey design choice is very important to avoid bias and increase the survey cost-efficiency. It can have a strong effect on the sample size needed to achieve some targeted accuracy on results. And on the final cost of the procedure. The sequential process we expose here melt design based and model based sampling theories. Its objectives is helping practitioners defining a sampling design and a number of samples for their survey when inference to the whole population is wanted. The main idea is to mathematically reconstruct the...

CO2 Allowance Allocation in the Regional Greenhouse Gas Initiative and the Effect on Electricity Investors AgEcon
Burtraw, Dallas; Kahn, Danny; Palmer, Karen L..
The Regional Greenhouse Gas Initiative (RGGI) is an effort by nine Northeast and Mid-Atlantic states to develop a regional, mandatory, market-based cap-and-trade program to reduce greenhouse gas (GHG) emissions from the electricity sector. The initiative is expected to lead to an increase in the price of electricity in the RGGI region and beyond. The implications of these changes for the value of electricity-generating assets and the market value of the firms that own them depends on the initial allocation of carbon dioxide allowances, the composition of generating assets owned by the firm, and the locations of those assets. Changes in asset values inside the RGGI region may be positive or negative, whereas changes outside of the RGGI region are almost...

The Effect on Asset Values of the Allocation of Carbon Dioxide Emission Allowances AgEcon
Burtraw, Dallas; Palmer, Karen L.; Bharvirkar, Ranjit; Paul, Anthony.
Paradoxically, owners of existing generation assets may be better off paying for carbon dioxide emission allowances than having them distributed for free. This analysis shows that it takes just 7.5% of the revenue raised under an auction to preserve the asset values of existing generators.

Potential of differentiated payment levels based on standard cost approaches: A case study of selected rural development measures in Germany AgEcon
Offermann, Frank; Nieberg, Hiltrud; Hecht, Judith.
In accordance with EU regulations, payment levels for several measures of rural development programs are calculated on the basis of standard cost approaches, using 'typical’ or average figures for costs incurred and income forgone. Resulting uniform payment rates have been frequently discussed and criticised as being inefficient, having a low cost-effectiveness and generating excessive windfall profits. However, few empirical studies exist which quantitatively examine potentials of a more differentiated standard cost approach. By using German farm accountancy data, this study analyses effects of a payment differentiation according to regional and farm individual characteristics on producer rents, budget expenditures and economic efficiency. Preliminary...

Towards a Resource Economics for Adaptive Managers AgEcon
Marshall, Graham R..
Adaptive management has become one of the catchphrases of the sustainable development literature, and is referred to increasingly in natural resource policy deliberations. Its advocates argue that natural resource sustainability issues are addressed more realistically and usefully as complex adaptive systems than as mechanistic systems. Resource economics has conventionally analysed such issues mechanistically, through the method of comparative statics. This paper explores the consequent limitations of conventional resource economics in supporting adaptive management, and offers signposts towards a resource economics with fewer of these limitations.

Does Scale Matter? Cost Effectiveness of Agricultural Nutrient Abatement When Target Level Varies AgEcon
Iho, Antti.
Agricultural production is facing high requirements on nutrient runoff reduction. Furthermore, the reductions should by done efficiently. For instance, the European Water Framework Directive calls for cost-effectiveness from schemes of measures to fulfill the target of good water quality in European river basins. In this paper we analyse the implications of target level variation on efficiency properties of agricultural phosphorus abatement. We analyse the robustness of cost-effectiveness as the scheme of measures is adopted from another, identical river basin with different target level on total phosphorus abatement. We find that even between homogeneous regions the cost-effective scheme of measures is unique for all target levels of reduction, and that...

Environmental Law and Public Policy AgEcon
Revesz, Richard L.; Stavins, Robert N..
This chapter provides an economic perspective of environmental law and policy with regard to both normative and positive dimensions. It begins with an examination of the central problem in environmental regulation: the tendency of pollution generators in an unconstrained market economy to externalize some of the costs of their production, leading to an inefficiently large amount of pollution. We examine the ends of environmental policy, that is, the setting of goals and targets, beginning with normative issues, notably the Kaldor-Hicks criterion and the related method of assessment known as benefit-cost analysis. We examine this analytical method in detail, including its theoretical foundations and empirical methods of estimation of compliance costs and...

Allocation of CO2 Emissions Allowances in the Regional Greenhouse Gas Cap-and-Trade Program AgEcon
Burtraw, Dallas; Palmer, Karen L.; Kahn, Danny.
Cap-and-trade programs for air emissions have become the widely accepted, preferred approach to cost-effective pollution reduction. One of the important design questions in a trading program is how to initially distribute the emissions allowances. Under the Acid Rain program created by Title IV of the Clean Air Act, most emissions allowances were distributed to current emitters on the basis of a historic measure of electricity generation in an approach known as grandfathering. Recent proposals have suggested two alternative approaches: allocation according to a formula that is updated over time according to some performance metric in a recent year (the share of electricity generation or something else) and auctioning allowances to the highest bidders....

Cost Savings Sans Allowance Trades? Evaluating the SO2 Emission Trading Program to Date AgEcon
Burtraw, Dallas.
Title IV of the 1990 amendments to the Clean Air Act initiated a historic experiment in incentive-based environmental regulation through the use of tradable allowances for emission of sulfur dioxide by electric generating facilities. To date, relatively little allowance trading has taken place; however, the costs of compliance have been much less than anticipated. The purpose of this paper is to address the apparent paradox that the allowance trading program may not require (very much) trading to be successful. Title IV represented two great steps forward in environmental regulation: first a move toward performance standards and second formal allowance trading. The first step has been sufficient to date for improving dynamic efficiency and achieving...

Modeling environmental risk and land management trade-offs in the Great Barrier Reef catchment AgEcon
Mallawaarachchi, Thilak; Mazur, Kasia; Lawson, Kenton.
We develop a catchment scale modeling framework to identify cost-effective strategies for joint onsite abatement and offsite mitigation of land-based pollution from agricultural activities that pose a risk to water quality in the Great Barrier Reef (GBR). An illustrative example of the Barron catchment in north Queensland is used to demonstrate an approach to specify social planner’'s problem for non-point source pollution management as a cost minimisation model to meet a specified reduction in land-based pollution emissions at the receiving waters of GBR. We focus on the tradeoffs between onsite pollution control and offsite pollution mitigation under a collective contract for nutrient reduction at a sub-catchment level and discuss implementation options.

Environmental Economics AgEcon
Stavins, Robert N..
This article, prepared for the forthcoming second edition of the New Palgrave Dictionary of Economics, provides an overview of the economics of environmental policy. Included are the setting of goals and targets, notably the Kaldor-Hicks criterion, and the related method of assessment known as benefit-cost analysis. Also reviewed are the means of environmental policy, that is, the choice of specific policy instruments, featuring an examination of potential criteria for assessing alternative instruments, with focus on cost-effectiveness. The theoretical foundations and experiential highlights of individual instruments are reviewed, including conventional command-and-control mechanisms and market-based instruments.

Comparison at Dairy Farm Level of Different Policies to Decrease Nutrient Losses to Ground and Surface Waters in the Netherlands AgEcon
Berentsen, Paul B.M..
This paper describes and compares two governmental policies that aim to decrease nutrient losses from farming to ground and surface waters in the Netherlands. The mineral bookkeeping system (MINAS) is the first policy. It is applied in the Netherlands since 1998 and it is based on a farm gate balance approach. This national policy was definitely rejected on October 2, 2003 by the EU Court of Justice as it was considered not to comply fully with the EU Nitrate Directive. Consequently, the Netherlands developed the Application Standards Policy (ASP) based on a soil balance approach which will replace MINAS starting 2006. Especially for dairy farming, that combines plant and animal production, nutrient input and output at soil level are hard to determine as...

The Ten-Year Rule: Allocation of Emission Allowances in the EU Emission Trading System AgEcon
Ahman, Markus; Burtraw, Dallas; Kruger, Joseph; Zetterberg, Lars.
In its guidance on National Allocation Plans (NAPs), the European Commission has discouraged Member States from adopting allocation methodologies that would provide incentives to firms affecting their compliance behavior. The purpose is to promote economic efficiency and to prevent strategic behavior that deviates from individual and collective cost-minimization. For example, some methodologies would reward one type of compliance investment over another. To discourage such actions, the EU Emission Trading System guidelines prohibit ex post redistribution of emission allowances within an allocation period based on behavior in that period. Similarly, the Commission has indicated that decisions about the initial distribution of allowances in the second phase...

Towards a cost-effectiveness analysis of the measurement of biodiversity indicators AgEcon
Targetti, Stefano; Viaggi, Davide; Cuming, David.
A comprehensive quantification of biodiversity in farming systems would require a very significant amount of work (and funds) even for a small area. Therefore, biodiversity indicators are needed to solve the problem of the measurement feasibility. Even though the issue of cost and effectiveness is central for the evaluation of the indicators, only the latter is discussed in detail in the scientific literature. This work presents a cost analysis based on the direct gathering of records from a farm-scale biodiversity survey (EU-FP7, BioBio - “Indicators for biodiversity in organic and low-input farming systems”) where the analysis of costs is part of the project. It is a simple method for comparing different indicators by their ratio of cost/effectiveness....

Direct Payments for Environmental Services from Mountain Agriculture in Japan: Evaluating its Effectiveness and Drawing Lessons for Developing Countries AgEcon
Sakuyama, Takumi.
This article evaluates the effectiveness of ex-post targeting of the direct payment program for mountain agriculture in Japan. A regression analysis explaining the entry into the program shows that the farm profitability and the production cost were significant positive and negative factor, respectively, in determining the uptake, while the efforts by local governments were a robust factor in facilitating the enrollment. These findings imply ineffective ex-post targeting and call for the differentiation of the premium, alternative incentives to promote forestation for the un-enrolled fields and additional funds targeted to those prefectures with the low uptake ratio. Lessons drawn from the Japanese experience for effective incentive measures in developing...
