rethinking ecosystem services to better address and navigate cultural values ecosystem service approaches have become a prominent basis for planning and management cultural services and non use values are included in all major typologies and present some of the most compelling reasons for conserving ecosystems though many barriers exist to their explicit characterization the values that conform least well to economic assumptions variously lumped together with as cultural services have proven elusive in part because valuation is complicated by the properties of intangibility and incommensurability which has in turn led to their exclusion from economic valuation we argue that the effectiveness of the ecosystem services framework in decision making is thwarted by i conflation of services values and benefits and ii failure to appropriately treat diverse kinds of values we address this challenge by 1 distinguishing eight dimensions of values which have implications for appropriate valuation and decision making 2 demonstrating the interconnected nature of benefits and services and so the ubiquity of intangible values 3 discussing the implications of these propositions for ecosystem services research and 4 outlining briefly a research agenda to enable decision making that is ecologically appropriate and socially just because many ecosystem services co produce cultural benefits full characterization of services must address non material values through methods from diverse social sciences

does public insurance crowd out private insurance the cost of expanding public sector health programs depends critically on the extent to which public eligibility will cover just the uninsured or will crowd out existing private insurance coverage we estimate the extent of crowd out arising from the expansions of medicaid to pregnant women and children over the 1987 1992 period we estimate that approximately 50 percent of the increase in medicaid coverage was associated with a reduction in private insurance coverage this occurred largely because employees took up employer based insurance less frequently there is also some evidence that employers contributed less for insurance and that workers dropped coverage of dependents

to value or not to value that is not the question abstract should we reject money when we value nature like most environmentalists ecological economists are increasingly divided on this question synthesizing political ecology with ecological economics we argue that this way of framing the question is limited we propose a reformulation of the question into when and how to value with money and under what conditions we recommend four criteria for a sound choice environmental improvement distributive justice and equality maintenance of plural value articulating institutions and confronting commodification under neo liberalism we call for due attention to the socio political context within which a valuation is placed and the political goals it serves the relevance of this framework is demonstrated by applying it to three practical cases pollution damages water pricing and payments for ecosystem services

yes in my backyard spatial differences in the valuation of forest services and local co benefits for carbon markets in mexico forests provide many and large benefits including cost efficient climate change mitigation however international carbon markets have not stimulated the demand for forestry offsets domestic market mechanisms are emerging in many countries and forests could be highly valued through these policies as most of the benefits produced by forests are enjoyed locally here a choice experiment explores drivers of valuation and willingness to pay for forest carbon services in voluntary markets in mexico by comparing the valuation of citizens from four regions to test geographical preference for projects n 645 findings from multinomial logit models show valuation of forest carbon services is transferable and citizens would pay more for offsets from projects closer to their homes proximate forests provide a range of co benefits to local users including environmental services and opportunities for recreation factors related to valuation include sense of responsibility previous knowledge of carbon emissions previous visits to the sites regional identification and the valuation of local environmental services e g improvements in local air quality knowledge of spatial heterogeneity in valuation of the use of forest services can help to design market based instruments by identifying highly valued areas for environmental services programs and carbon markets

designing payments for environmental services in theory and practice an overview of the issues abstract payments for environmental services pes have attracted increasing interest as a mechanism to translate external non market values of the environment into real financial incentives for local actors to provide environmental services es in this introductory paper we set the stage for the rest of this special issue of ecological economics by reviewing the main issues arising in pes design and implementation and discussing these in the light of environmental economics we start with a discussion of pes definition and scope we proceed to review some of the principal dimensions and design characteristics of pes programs and then analyze how pes compares to alternative policy instruments finally we examine in detail two important aspects of pes programs their effectiveness and their distributional implications pes is not a silver bullet that can be used to address any environmental problem but a tool tailored to address a specific set of problems those in which ecosystems are mismanaged because many of their benefits are externalities from the perspective of ecosystem managers pes is based on the beneficiary pays rather than the polluter pays principle and as such is attractive in settings where es providers are poor marginalized landholders or powerful groups of actors an important distinction within pes is between user financed pes in which the buyers are the users of the es and government financed pes in which the buyers are others typically the government acting on behalf of es users in practice pes programs differ in the type and scale of es demand the payment source the type of activity paid for the performance measure used as well as the payment mode and amount the effectiveness and efficiency of pes depends crucially on program design

market based instruments economists have long recommended market based instruments for efficient environmental policy making taxes tradable permits auctions of property rights etc so why is progress on them so slow the reality is that any environmental policy faces many political institutional and technical obstacles but market based instruments face more than most many relate to false perceptions although some are real most have solutions some do not

photovoltaic electricity production in brazil a stochastic economic viability analysis for small systems in the face of net metering and tax incentives abstract currently in addition to the search for sustainable development there is increased pressure for a change in consumption and production of energy patterns in brazil in this scenario net metering is an important mechanism fostering dissemination of small photovoltaic pv solar systems as complementary support to net metering a tax exemption is currently being offered in some brazilian states thus the objective of the present study is to analyze the impact of tax exemption on the circulation of goods and services and the returns and risks of the pv microgeneration project in four cities located in different regions of brazil belem petrolina uberaba and uruguaiana the analysis is performed using the monte carlo simulation mcs wherein uncertainties related to the financial and environmental variables are considered the results of the stochastic economic viability analysis allowed us to conclude that the exemption of tax on circulation of goods and services icms is fundamental to make pv microgeneration viable in brazil in the cities analyzed pv microgeneration presented economic unfeasibility to the investor when the icms is charged when considering the icms exemption policy the cities of petrolina and belem obtained high probabilities of viability in relation to the risk analysis pv microgeneration obtained the best results in petrolina both in terms of the condition of collection and exemption of icms there is high potential for harness solar throughout the brazilian territory however due to the current evolution stage and the productive chain of the brazilian pv industry high costs limit the expansion of this clean energy generation technology the findings of this study could assist policymakers in evaluating this incentive program highlighting that this tax exemption directly meets one of the objectives for which the icms was created which is to encourage the development of productive sectors such as pv industry

revisiting the concept of payments for environmental services this article revisits the payments for environmental services pes concept and reviews existing pes definitions based on weberian philosophy of science it is argued that an ideal pes type strongly embedded in pes theory is needed to understand their logic many broader empiricist definitions fail to distinguish pes from the larger generic family of positive environmental incentives thus eroding their meaning by excessive vagueness arguably pes definitions should focus on describing a functional tool rather than normatively integrating desirable pes outcomes a modified narrow pes definition is proposed outlining conditionality as the single defining feature avoiding the buyer seller terms and linking pes to offsite externalities extensive explanatory guidelines address many valid conceptual concerns raised in the recent pes literature

endogenous cost effectiveness analysis and health care technology adoption abstract increased health care spending has placed pressure on public and private payers to prioritize spending cost effectiveness ce analysis is the main tool used by payers to prioritize coverage of new therapies we argue that reimbursement based on ce is subject to a form of the lucas critique the goals of ce policies may not materialize when firms affected by the policies respond optimally to them for instance because costs in ce analysis reflect prices set optimally by firms rather than production costs observed ce levels will depend on how firm pricing responds to ce policies observed ce is therefore endogenous when ce is endogenously determined policies aimed at lowering spending and improving overall ce may paradoxically raise spending and lead to the adoption of more resource costly treatments we empirically illustrate whether this may occur using data on public coverage decisions in the united kingdom

payments for ecosystem services rife with problems and potential for transformation towards sustainability abstract payments for ecosystem services pes programs are one prominent strategy to address economic externalities of resource extraction and commodity production improving both social and ecological outcomes but do pes and related incentive programs achieve that lofty goal along with considerable enthusiasm pes has faced a wide range of substantial critiques in this paper we characterize seven major classes of concerns associated with common pes designs and use these as inspiration to consider potential avenues for improvements in pes outcomes and uptake the problems include 1 new externalities 2 misplacement of rights and responsibilities 3 crowding out existing motivations 4 efficiency equity tradeoffs 5 monitoring costs 6 limited applicability and 7 top down prescription alienating agency as currently practiced many pes programs are thus of limited benefit and even potentially detrimental to sustainability from this dire conclusion we highlight several innovations that might be combined and extended in a novel approach to pes that may address all seven problems recognizing that pes necessarily articulate and even normalize values our proposed approach entails designing these institutions intentionally to articulate rights and responsibilities conducive to sustainability those we might collectively seek to entrench problems remain and new ones may arise but the proposed approach may offer a way to reimagine pes as a major social and economic tool for enabling sustainable relationships with nature conserving and restoring ecosystems and their benefits for people now and in the future

the insurance value of medical innovation abstract economists think of medical innovation as a valuable but risky good producing health benefits but increasing financial risk for consumers and healthcare payers this perspective overlooks how innovation can lower physical risks borne by healthy patients facing the prospect of future disease we present an alternative framework that accounts for all these sources of value and links them to the value of healthcare insurance we show that any innovation worth buying reduces overall risk and generates positive insurance value on its own we conduct a stylized numerical exercise to assess the potential empirical significance of our insights our calculations suggest that conventional methods meaningfully understate the value of historical health gains and disproportionately undervalue treatments for the most severe illnesses where physical risk to consumers is the costliest these calculations also suggest that the value of physical insurance from new technologies may exceed the financial spending risk that they pose

the ideology of efficiency searching for a theory of policy analysis the potential pareto improvement criterion and other measures of economic efficiency do not pass the test of consistency and coherence within economic theory nor do such measures accord with what public decision makers seek in policy advice from economists such efficiency measures are nonetheless durable components of the ideology of economics in general and benefit cost analysis in particular the objectivity of the policy scientist has been confused with the objectivity of the science while economic efficiency has no claim to objectivity the policy scientist can be an objective analyst of policy choices

medical care costs how much welfare loss hardly a week goes by without a front page newspaper article on rising health care costs and the uninsured in this article i focus mainly on costs arguing that the issue has been somewhat misconceived while the level of medical care spending in the u s is a cause for concern the welfare losses associated with rises in that level of spending may not be as large as the public rhetoric can make them seem in fact cost containment may not be as urgent as is widely supposed and some proposed cost containment policies may result in welfare losses for the insured and even increase the number of uninsured

the evaluation of feed in tariff regulation of turkey for onshore wind energy based on the economic analysis abstract renewable energy sources have become popular with the technological developments the increase in the price of fossil fuels and the environmental concerns these factors have also prompted turkey to utilize her rich renewable energy sources to meet her increasing electricity demand which is around 7 annually therefore the renewable energy law was enacted in 2005 to incentivize the utilization of domestic renewable sources with feed in tariffs in this study onshore wind energy potential of turkey is analyzed to find out whether these regulations and incentives will help the utilization of onshore wind energy potential to that end some background information about technology and cost of onshore wind power plants the wind energy potential of turkey and the current regulatory framework related to wind energy are explained then a model is set up to conduct economic analysis by calculating npv for the base case scenario and under the uncertain environment the results show that an onshore wind energy potential of about 13 gw having a wind speed of 7 5 m s or higher can be utilized profitably with the current feed in tariff as the wind capacity of more than 100 gw cannot be utilized economically

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

new foundations for ecological economics abstract ecological economics has been repeatedly described as transdiciplinary and open to including everything from positivism to relativism i argue for a revision and rejection of this position in favour of realism and reasoned critique looking into the ontological presuppositions and considering an epistemology appropriate for ecological economics to meaningfully exist requires rejecting the form of methodological pluralism which has been advocated since the start of this journal this means being clear about the differences in our worldview or paradigm from others and being aware of the substantive failures of orthodox economics in addressing reality this paper argues for a fundamental review of the basis upon which ecological economics has been founded and in so doing seeks improved clarity as to the competing and complementary epistemologies and methodologies in part this requires establishing serious interdisciplinary research to replace superficial transdisciplinary rhetoric the argument places the future of ecological economics firmly amongst heterodox economic schools of thought and in ideological opposition to those supporting the existing institutional structures perpetuating a false reality of the world s social environmental and economic systems and their operation

an institutional analysis of payments for environmental services abstract in this paper the characteristics and functioning of pes is analyzed from an institutional perspective while in theory pes is seen as a market solution to environmental problems as an alternative to state hierarchical and community governance a review of a large amount of case studies shows that pes in practice depends rather fundamentally on state and or community engagement hence pes are foremost a reconfiguration of the roles of public bodies and communities becoming core intermediaries or buyers first to establish pes rights to the land that delivers the environmental service must be clarified this demands public action second transacting over environmental amenities is very costly creating markets for environmental services depends therefore crucially on state and community facilitation hence buyers are often public agencies high transaction costs also influence price setting payments do not follow the market format as intermediaries frequently are setting the price with users often being unaware even of the fact that they pay finally the distinction between payments as incentives and as fair compensations is emphasized while payments may strengthen community relations and simplify action for environmental care they may also introduce a purely instrumental logic and in some cases worsen the environmental status by crowding out environmental virtues for the future greater awareness of these dynamics is warranted

innovation and the welfare effects of public drug insurance rewarding inventors with inefficient monopoly power has long been regarded as the price of encouraging innovation prescription drug insurance escapes that trade off and achieves an elusive goal lowering static deadweight loss without reducing incentives for innovation as a result of this feature the public provision of drug insurance can be welfare improving even for risk neutral and purely self interested consumers the design of insurers cost sharing schedules can either reinforce or mitigate this result schedules that impose higher consumer cost sharing requirements on more expensive drugs help ensure that insurance subsidies translate into higher utilization rather than pure increases in manufacturer profits moreover some degree of price negotiation with manufacturers is likely to be welfare improving but the optimal degree depends on the size of such transactions costs as well as the social cost of weakening innovation incentives by lowering innovator profits these results have practical implications for the evaluation of public drug insurance programs like the us medicaid and medicare part d programs along with european insurance schemes

in markets we trust setting the boundaries of market based instruments in ecosystem services governance abstract a growing tendency to frame environmental problems as a failure to price ecosystem services has coincided with the rise of so called market based instruments mbis the aim of this introductory article to the special section in markets we trust contrasting views on the performance and legitimacy of market based instruments in global environmental governance is to promote critical reflection about the nature scope and limits of mbis in ecosystem services governance and to provide guidance on where the boundaries for the application of markets ought to be set first we examine the role that methodological assumptions and implicit normative positions play in shaping academic perception of the effectiveness and legitimacy of mbis second we examine mbis in the broader ideological context and socio political processes that have favored their development and implementation third we test claims of the literature on mbis against insights and data from case studies presented in the special section fourth we discuss the scope and limits of markets in ecosystem services governance in the light of biophysical institutional and normative boundaries we end with a summary of concluding remarks from the special section and by identifying critical tasks for the scientific and policy agenda on ecosystem services governance

governance land and distribution a discussion on the political economy of community based conservation abstract the effectiveness of community based conservation cbc has been under discussion through the review of cbc initiatives in developing countries we contribute to the debate by analysing how players influence different factors that determine the outcomes of cbc we highlight several points first the promise of benefits has been overshadowed by constraints on the extraction of natural resources along with the use of governmental schemes to extract partially the rents from cbc which has left little to share inside the communities second cbc design and implementation has often overlooked the asymmetries of power within the community and at the individual level which has produced unequal access to the design decision making and outcomes of this activity third while the elites have had a determinant role in shaping the governance of cbc external agents promotion of cbc has tended to reproduce the existent negotiating power at the community local and national levels fourth land contestation plays a key role in the dynamics of relationship and conflict between the governments corporate interests and the communities finally cbc adaptation to new scenarios depends critically on the process of community empowerment and the building of networks with external agents

green public procurement of certified wood spatial leverage effect and welfare implications certified and conventional products are not traditional substitute goods green public procurement stimulates certification globally but not in each region public procurement of the cheaper unsustainable product does not maximise welfare increasing the price premium for certified wood creates a trade barrier the high costs of forest certification exclude vulnerable producers

can redd still become a market ruptured dependencies and market logics for emission reductions in brazil abstract during almost 20 years of political debate on the nature of payments for ecosystem services pes these schemes have been characterized mostly as a non market approach even though attempts to transform them into market instruments has persistently recurred in these debates one notable example is the materialization of reducing emissions from deforestation and forest degradation redd in brazil where a sustainable development discourse dominates national forest governance at the expense of a carbon commodification discourse this research paper adopts a foucauldian approach to plot the epistemological foundations of the market logics that still influence redd institutionalization in brazil to a large extent and thereby reproduce what we define as a ruptured dependence on nature more specifically we recognize ruptured dependence in the three building blocks of market instruments namely singularization monetary valuation and appropriation our analysis shows that redd institutions have retained the singularization and monetary valuation of emission reductions even though the appropriation processes have rejected the possibility of exchange and instead emphasized the national ownership of emission reductions however appropriation remains a highly politicized process that is sensitive to criticism and open to calls for alternative approaches that are closer to ruptured dependence

the history of ecosystem services in economic theory and practice from early notions to markets and payment schemes article i nfo this paper reviews the historic development of the conceptualization of ecosystem services and examines critical landmarks in economic theory and practice with regard to the incorporation of ecosystem services into markets and payment schemes the review presented here suggests that the trend towards monetization and commodification of ecosystem services is partly the result of a slow move from the original economic conception of nature s benefits as use values in classical economics to their conceptualization in terms of exchange values in neoclassical economics the theory and practice of current ecosystem services science are examined inthelight ofthis historicaldevelopment from thisreview we conclude thatthefocus onmonetary valuation and payment schemes has contributed to attract political support for conservation but also to commodify a growing number of ecosystem services and to reproduce the neoclassical economics paradigm and the market logic to tackle environmental problems

contesting legitimacy of voluntary sustainability certification schemes valuation languages and power asymmetries in the roundtable on sustainable palm oil in colombia voluntary certification schemes aimed at assuring producer compliance with a set of sustainability criteria have emerged as market based instruments mbis of sustainability governance however the impacts they tackle can be part of a complex arena of socio environmental conflict where values and powers of business and local actors compete legitimacy of these schemes not only results from compliance by business actors but also depends on acceptance by local actors affected by or resisting the industries that these mechanisms aim to govern this paper explores the influence of different local actors values and powers on legitimacy granting or contestation by local actors during national processes of sustainability criteria development we analyse the case of the roundtable on sustainable palm oil rspo in colombia using an approach that combines concepts of ecological economics and political ecology with the legitimacy literature based on critical sociology in colombia the palm oil industry led the initiative to implement certification under national interpretation of rspo principles and criteria however the national interpretation process revealed power asymmetries among stakeholders and clashes between their different values this resulted in strong contestation of rspo legitimacy by local actors who resist expansion of oil palm cultivation

technology growth and expenditure growth in health care in the united states health care technology has contributed to rising survival rates yet health care spending relative to gdp has also grown more rapidly than in any other country we develop a model of patient demand and supplier behavior to explain these parallel trends in technology growth and cost growth we show that health care productivity depends on the heterogeneity of treatment effects across patients the shape of the health production function and the cost structure of procedures such as mris with high fixed costs and low marginal costs the model implies a typology of medical technology productivity i highly cost effective home run innovations with little chance of overuse such as anti retroviral therapy for hiv ii treatments highly effective for some but not for all e g stents and iii gray area treatments with uncertain clinical value such as icu days among chronically ill patients not surprisingly countries adopting category i and effective category ii treatments gain the greatest health improvements while countries adopting ineffective category ii and category iii treatments experience the most rapid cost growth ultimately economic and political resistance in the u s to ever rising tax rates will slow cost growth with uncertain effects on technology growth

ecosystems contingent valuation and ethics the case of wetland re creation this paper addresses a current issue in environmental valuation namely the extent to which environmental preferences depart from the usual economic paradigm to incorporate some lexicographic elements after a theoretical discussion the paper reviews attempts to explore this question empirically by supplementing contingent valuation analyses with an exploration of the motives behind willingness to pay responses including zero bids and refusals to answer this is followed by the presentation of new evidence investigating respondents willingness to pay for the creation of a wetland taken from 713 personal interviews of the british public 2000 elsevier science b v all rights reserved

cost effectiveness analysis and innovation while cost effectiveness ce analysis has provided a guide to allocating often scarce resources spent on medical technologies less emphasis has been placed on the effect of such criteria on the behavior of innovators who make health care technologies available in the first place a better understanding of the link between innovation and cost effectiveness analysis is particularly important given the large role of technological change in the growth in health care spending and the growing interest of explicit use of ce thresholds in leading technology adoption in several westernized countries we analyze ce analysis in a standard market context and stress that a technology s cost effectiveness is closely related to the consumer surplus it generates improved ce therefore often clashes with interventions to stimulate producer surplus such as patents we derive the inconsistency between technology adoption based on ce analysis and economic efficiency indeed static efficiency dynamic efficiency and improved patient health may all be induced by the cost effectiveness of the technology being at its worst level as producer appropriation of the social surplus of an innovation is central to the dynamic efficiency that should guide ce adoption criteria we exemplify how appropriation can be inferred from existing ce estimates for an illustrative sample of technologies considered we find that the median technology has an appropriation of about 15 to the extent that such incentives are deemed either too low or too high compared to dynamically efficient levels ce thresholds may be appropriately raised or lowered to improve dynamic efficiency

atmospheric externalities and environmental taxation abstract the paper reviews the theory of environmental taxation under first best and second best conditions it argues that negative environmental externalities lead to reductions of the provision of public goods while investment in abatement increases the supply of public goods together with optimal tax rules the paper therefore also derives conditions for the optimal use of resources on abatement after brief discussions of the dimensions of time and uncertainty tax reform and the double dividend and taxes vs quotas the optimal tax model is applied to the problem of global warming with a discussion of the particular incentive problems that arise in designing and implementing global climate policy

accounting for future costs in medical cost effectiveness analysis most medical cost effectiveness analyses include future costs only for related illnesses but this approach is controversial this paper demonstrates that cost effectiveness analysis is consistent with lifetime utility maximization only if it includes all future medical and non medical expenditures estimates of the magnitude of these future costs suggest that they may substantially alter both the absolute and relative cost effectiveness of medical interventions particularly when an intervention increases length of life more than quality of life in older populations current methods overstate the cost effectiveness of interventions which extend life compared to interventions which improve the quality of life

tax avoidance and the deadweight loss of the income tax traditional analyses of the income tax greatly underestimate deadweight losses by ignoring its effect on forms of compensation and patterns of consumption the full deadweight loss is easily calculated using the compensated elasticity of taxable income to changes in tax rates because leisure excludable income and deductible consumption are a hicksian composite good microeconomic estimates imply a deadweight loss of as much as 30 of revenue or more than ten times harberger s classic 1964 estimate the relative deadweight loss caused by increasing existing tax rates is substantially greater and may exceed 2 per 1 of revenue

markets in environmental governance from theory to practice abstract the aim of this paper is to clarify what is meant by markets for ecosystem services es the defining characteristic of markets is interaction through trade two main dimensions are identified as basis for classifying markets in es firstly we have markets with and without intermediaries secondly some markets for es are created by defined liabilities like caps on emissions while other trades come about voluntarily altogether six forms of markets are identified with two being incomplete the paper also offers an analysis of the most important existing markets for es using the developed classification regarding payments for ecosystem services pes most are not markets not even incomplete this is so as most resources are raised through taxes or fees command not trade moreover most payments are best characterized as subsidies cap and trade systems like those for carbon qualify as markets but depend crucially on the politically defined cap moreover it is this cap that protects the environment while the idea with markets in es is to escape command and control it is observed that c c is essential for these markets to work

ecosystem services concepts and approaches in conservation just a rhetorical tool many commentators have raised questions about the recent focus on ecosystem services es concepts in conservation but little empirical analysis exists we present a novel empirical analysis using interviews and q methodology to examine how conservation practitioners and organisations are interpreting and using es concepts and associated approaches we find that these concepts are being adopted for instrumental imperatives to broaden constituencies and with an expectation of extending funding sources we uncover concerns within conservation that the utilitarian emphases of es concepts may compromise the ability to make non utilitarian arguments for nature in the future in relation to changing practice we examine shifts in partnerships and funding where es ideas provide a shared language about flows of value apparently accelerating the integration of conservation and the private sector whilst many respondents noted the significance of shifts related to es ideas some attempted to play these down presenting their organisation s adoption of these ideas as just a rhetorical tool however we argue that the adoption of es concepts cannot be presented as solely rhetorical given that these increasingly underpin and inform planning tools and policy instruments

the distortionary effects of government procurement evidence from medicaid prescription drug purchasing in 2003 the federal state medicaid program provided prescription drug coverage to more than 50 million people to determine the price that it will pay for each drug medicaid uses the average private sector price when medicaid is a large part of the demand for a drug this creates an incentive for its maker to increase prices for other health care consumers using drug utilization and expenditure data for the top 200 drugs in 1997 and in 2002 we investigate the relationship between the medicaid market share mms and the average price of a prescription our estimates imply that a 10 percentage point increase in the mms is associated with a 7 to 10 percent increase in the average price of a prescription in addition the medicaid rules increase a firm s incentive to introduce new versions of a drug in order to raise price we find empirical evidence that firms producing newer drugs with larger sales to medicaid are more likely to introduce new versions taken together our findings suggest that government procurement rules can alter equilibrium price and product proliferation in the private sector

wind power generation an impact analysis of incentive strategies for cleaner energy provision in brazil brazil has adopted various strategies to encourage alternative renewable energy sources in pursuit of cleaner and sustainable energy production to this end strategies should support the reduction of the financial risk for potential investors in the renewable energy market therefore this study aims to analyze the impact of incentive strategies on the financial risk of wind power generation projects in brazil in different marketing environments from a quantitative approach using monte carlo simulation in three scenarios we evaluate the impact of funding from the national development bank and participation in the clean development mechanism in the financial returns of the investor in a regulated contracting environment and free contracting environment measured by the net present value we conduct a statistical analysis to find out if there were statistically significant differences in investor risk in each scenario the main results of the study are as follows the wind speed the selling price of energy and disbursement for the investment have the most significant impact on the financial return the project viability probability is greater than 85 in all scenarios regardless of the marketing environment the regulated market is less risky for the producer than the free market since there is a statistically significant difference in net present value variances for all scenarios in the regulated contracting environment funding is critical to reducing risk and carbon credit trading is not a suitable policy for providing financial security to renewable energy producers thus we conclude that in brazil the contracting of projects from auctions in the regulated contracting environment with the support of the national development bank has been important for neutralizing the producer s financial risks

scope and limits of the market mechanism in environmental management abstract this paper tries to evaluate the role of the market mechanism in environmental management and warns against reductionist views on the causes and remedies of environmental damages according to some of these views proper pricing of the environment and extensive use of market mechanisms in environmental management would solve environmental problems but various conditions tell against such simplifications namely the complex causality behind environmental damages the complexity of the functions and values of nature as well as limitations of the market mechanism in coping with the functions and services of nature several of those limitations the difficulties of defining and enforcing property rights to nature s functions and services the pervasiveness of externalities conditioned by the public goods characteristics of many environmental functions and values the difficulties in enticing processing and using information about environmental goods and the high transaction costs caused by all these circumstances often rule out contracts and trading of environmental services it is less known that the basic cause of market existence and extension namely specialization and division of labour have negative environmental effects with respect to environmental policy conceptual problems are analyzed while all kinds of environmental management mechanisms have a regulatory function only quantity mechanisms as a subset of incentive mechanisms are market mechanisms the choice of relevant environmental policy instrument is conditioned by many considerations the issue of the superior efficiency properties of market mechanisms in environmental management is not yet settled satisfactorily extensive empirical tests are still lacking

the pes conceit revisiting the relationship between payments for environmental services and neoliberal conservation payments for environmental services pes has become a popular means to neoliberalize biodiversity conservation throughout the world yet research on pes is increasingly focused on debating exactly how neoliberal programmes really are documenting complexities in pes implementation and concluding that few programmes are very market based in practice while we agree that ideal neoliberal implementation of pes does not and cannot exist we argue that focusing only on micro politics misunderstands the importance of analysing pes as a form of neoliberal conservation the question is not just whether pes is innately neoliberal but how it functions within a broader neoliberal political economy by focusing on the overarching governance and power structures that gave rise to pes in the first place we more clearly see what we call the pes conceit namely that the approach implicitly accepts neoliberal capitalism as both the problem and the solution to the ecological crisis this strategy is not only contradictory but also commonly fails to achieve intended outcomes falling far short of conservation objectives while also often exacerbating socioeconomic inequality this problematic conceit we conclude cannot be addressed through only micro oriented studies it demands connecting micro and macro political economic analyses to confront broader neoliberal power structures

payments for ecosystem services from local to global abstract payment for ecosystem services pes is becoming increasingly popular as a way to manage ecosystems using economic incentives the environmental economics approach to pes tries to force ecosystem services into the market model with an emphasis on efficiency the ecological economics approach in contrast seeks to adapt economic institutions to the physical characteristics of ecosystem services prioritizing ecological sustainability and just distribution and requiring a transdisciplinary approach this paper summarizes the results of a participatory atelier workshop held in costa rica we developed a set of principles the heredia declaration for pes systems and report on evolving initiatives in several countries we discuss how the distinction between ecosystem goods which are stock flow resources and ecosystem services which are fund service resources and the physical characteristics of the fund services affect the appropriate institutional form for pes we conclude that pes systems represent an important way to effectively manage fund service resources as public goods and that this represents a significant departure from conventional market institutions

designing more efficient markets lessons from los angeles smog control market based approaches for environmental protection are beginning to take root around the world this article attempts to improve our understanding of the performance of environmental markets by constructing and evaluating an information base on trades in los angeles which includes the first detailed data on trading prices the analysis suggests that trading activity has been shaped by the detailed regulations governing the market in addition transaction costs have played a crucial role we argue that the move toward adopting market based approaches for environmental protection needs to be accompanied by a vigorous effort to assess the properties of these systems as they are actually implemented

performance of a cap and trade system for managing environmental impacts of shale gas surface infrastructure abstract governments across the globe are exploring ways to reduce the environmental and human health impacts created by shale energy production in active areas environmental regulations tend to be limited we apply established instruments to empirically estimated environmental impact abatement cost curves for the development of 56 sites in pennsylvania usa we compare the cost to industry of setting a cap on environmental impacts from land clearing and building of surface infrastructure under two regulations cap and trade versus a uniform inflexible regulation greatest differences in cost are achieved when firm level permits are allocated to reduce market wide potential impacts by 36 cap and trade achieved this cap at a cost of 0 05 of not developing and allowed all development to proceed the uniform inflexible regulation cost 32 of not developing for a similar outcome and prevented 18 of firms from developing cap and trade s performance depended on the regulator s ability to accurately allocate firm level permits that reflect developers options in extreme cases inaccurate allocations made cap and trade perform worse than other the approach we conclude that where developers differ in their ability and cost of minimizing impacts cap and trade should be explored as an inexpensive alternative to traditional approaches
