Paying for the hydrological services of Mexico's forests: Analysis, negotiations and results

Mexico faces both high deforestation and severe water scarcity. The Payment for Hydrological Environmental Services (PSAH) Program was designed to complement other policy responses to the crisis at the interface of these problems. Through the PSAH, the Mexican federal government pays participating forest owners for the benefits of watershed protection and aquifer recharge in areas where commercial forestry is not currently competitive. Funding comes from fees charged to water users, from which nearly US$18 million are earmarked for payments of environmental services. Applicants are selected according to several criteria that include indicators of the value of water scarcity in the region. This paper describes the process of policy design of the PSAH, the main actors involved in the program, its operating rules, and provides a preliminary evaluation. One of the main findings is that many of the program's payments have been in areas with low deforestation risk. Selection criteria need to be modified to better target the areas where benefits to water users are highest and behavior modification has the least cost, otherwise the program main gains will be distributive, but without bringing a Pareto improvement in overall welfare.     

Spatial targeting of payments for environmental services: A tool for boosting conservation benefits

Payments for environmental services (PES) have become an increasingly popular market-based instrument to translate external, non-market environmental services into financial incentives for landowners to preserve the ecosystems that provide the services. However, lack of spatial differentiation in the targeting mechanism may lead to efficiency losses. Addressing this challenge, we construct an applied site selection tool, which takes into account three variables that vary in space: environmental services provided, risks of losing those services, and participation costs. Using data from Costa Rica's Nicoya Peninsula, we empirically test the tool's potential to increase the financial efficiency of the forest-focused PES program in place. Results show that, given a fixed budget, efficiency increases radically if per hectare payments are aligned to landowners' heterogeneity in participation costs, involving opportunity, transaction and direct costs of protection, respectively. Selecting sites based on environmental service potential also moderately increases efficiency. Overall additionality could in the best case be doubled, but remains generally limited due to current low deforestation risks prevailing in Costa Rica. To take advantage of the high efficiency potentials of flexible payments, we propose inverse auction systems as a cost-effective approach for the determination of micro-level participation costs.     

Towards a unified scheme for environmental and social protection: Learning from PES and CCT experiences in developing countries

Environmental protection and poverty alleviation in the developing world are usually heralded as joint objectives. However, these two goals are often associated with different sectoral policy instruments. While so−called payments for environmental services (PES) are increasingly being promoted for environmental protection, poverty alleviation is increasingly addressed by conditional cash transfers (CCT) program. These instruments although aimed to achieve distinct objectives have a number of similarities and challenges in their design and implementation phases. This paper elaborates on these similarities and develops a unifying generic framework that is used to discuss the extent to which both approaches could be unified.     

Peering and Settlement in the Internet: An Economic Analysis

This paper explores the implications of Internet peering in the context of a model of competing, vertically integrated Internet Access Providers. We show that if regulation forbids settlement payments between firms, there will be under-investment in capacity and under-pricing of usage, both of which lead to excessive congestion. To overcome these problems, firms that are net providers of Internet infrastructure should be allowed to charge firms that are net users. We characterize the efficient level of these access payments, assuming usage can be appropriately measured. We find that refusal to peer and the charging of settlement payments may well be efficiency enhancing.     

Optimal design of pro-conservation incentives

Payments for environmental services (PES) schemes have become an increasingly accepted and popular mode for governmental and non-governmental agencies to use in addressing local and regional declines in ecosystem services. In PES schemes, payments can either be tied to indicators of actions for service provision or to indicators of the generated service itself. Performance payments are synonymous for this second group, i.e. payments are completely contingent on the procurement of an environmental good or service. Such a focus raises several practical issues during implementation. We review and translate key aspects of the economic theory of incentives into the context of performance payment schemes with special attention paid to two practical issues: risks outside the individual's control and distortion in the measurement of environmental services. Four different incentive payment approaches are presented and the effects of risk and distortion on optimal incentives are discussed. The investigation of each payment approach is accompanied by a discussion of examples from the field.     

Compensation payments for habitat heterogeneity: Existence, efficiency, and fairness considerations

Compensation payments for voluntary conservation measures have become an important tool for biodiversity conservation worldwide. Each year substantial financial resources are spent on such measures, particularly in the context of agri-environmental schemes. In Europe, a debate has started on whether this money is spent effectively. In response to this debate it has been suggested that a portfolio of measures leading to habitat heterogeneity be implemented. Although payments for heterogeneous conservation measures have been analysed in the literature, it has never been questioned that payments can be designed in a way that encourages enough land users to carry out each conservation measure within a portfolio of measures. The purpose of this paper is to demonstrate that such payments do not always exist. Moreover, in cases where payments for habitat heterogeneity exist the payment scheme may require overcompensation of the land users, posing a limit to both efficiency and fairness considerations.     

Paying for the environmental services of silvopastoral practices in Nicaragua

Agricultural landscapes can provide many valuable ecosystem services, but many are externalities from the perspective of farmers and so tend to be under-produced. This paper examines an effort to make direct payments for ecosystem services (PES) in an agricultural landscape. The Regional Integrated Silvopastoral Ecosystem Management Project is piloting the use of PES to induce adoption of silvopastoral practices in the Matiguás-Río Blanco area in Nicaragua. Silvopastoral practices could substantially improve service provision while retaining agricultural production, but they have found only limited acceptance among farmers. The Silvopastoral Project seeks to increase their adoption by paying farmers for the expected increase in biodiversity conservation and carbon sequestration services that these practices would provide. The Project developed an ‘environmental services index’ (ESI) and pays participants for net increases in ESI points. Although the Silvopastoral Project is still underway, it already appears to have succeeded in inducing farmers to increase substantially the use of practices that generate higher levels of ecosystem services. In the project's first two years, over 24% of the total area experienced some form of land use change. The area of degraded pasture fell by two thirds, while pastures with high tree density increased substantially, as did fodder banks and live fences. On-going monitoring indicates that these land use changes are in fact generating the desired services. Questions remain about the long-term sustainability of the approach, however. To ensure sustainability, long-term payments are likely to be needed, raising the question of how they will be financed. Payments by water users and by carbon buyers provide a partial answer to this challenge, but still leave many gaps.     

THE TREATMENT OF INTEREST AND FINANCIAL INTERMEDIARIES IN THE NATIONAL ACCOUNTS: THE OLD "BUNDLE" VERSUS THE NEW "UNBUNDLE" APPROACH

As is widely recognized both in the literature and by the practitioners, the treatment of financial intermediaries has been one of the most controversial issues in national accounting. This has been so largely because no one up to now has been able to define the output of banks and other financial intermediaries. In the present paper, a theory of services in general and of financial services in particular is used to demonstrate that financial intermediaries produce at least six commodity type services. Furthermore, it is argued that in order to solve the banking imputation problem it is necessary to separate the theory of interest rates from the theory of financial services and examine the interdependence between them. The gross interest rate must be unbundled because it contains three distinct components. These are, first, the pure interest rate, which reflects payment for a factor-type service; second, payments for six commodity-type services, which reflect the output of financial intermediaries; and, third, payments for unilateral transfers. The new unbundled approach is contrasted to the old bundle approach used and/or advocated by standard economic theory, the SNA, Sunga and the Ruggleses. Furthermore, it is recommended that payments for the pure interest rate be considered as part of income of the paying enterprise or sector while payments for financial services by enterprises to other enterprises should be considered as intermediate purchases.     

The working for water programme: Evolution of a payments for ecosystem services mechanism that addresses both poverty and ecosystem service delivery in South Africa

A payments for ecosystem services (PES) system came about in South Africa with the establishment of the government-funded Working for Water (WfW) programme that clears mountain catchments and riparian zones of invasive alien plants to restore natural fire regimes, the productive potential of land, biodiversity, and hydrological functioning. The success of the programme is largely attributed to it being mainly funded as a poverty-relief initiative, although water users also contribute through their water fees. Nevertheless, as the hydrological benefits have become apparent, water utilities and municipalities have begun to contract WfW to restore catchments that affect their water supplies. This emerging PES system differs from others in that the service providers are previously unemployed individuals that tender for contracts to restore public or private lands, rather than the landowners themselves. The model has since expanded into other types of ecosystem restoration and these have the potential to merge into a general programme of ecosystem service provision within a broader public works programme. There is a strong case for concentrating on the most valuable services provided by ecosystems, such as water supply, carbon sequestration, and fire protection, and using these as ‘umbrella services’ to achieve a range of conservation goals. The future prospects for expansion of PES for hydrological services are further strengthened by the legal requirement that Catchment Management Agencies be established. These authorities will have an incentive to purchase hydrological services through organisations such as WfW so as to be able to supply more water to their users.     

公立医院公益性问题研究

近年来,公众之所以会对"公立医院是否具有公益性"产生疑问,是源于社会上对"公立医院收费使它们丧失了公益性"的批评,而这种批评又混淆了公立医院提供医疗服务应不应当收费和医疗费用最终应当由谁支付这两个不同的问题。因此,文章在综合各种公益性概念并对公益性给出一个确切定义的基础上,分别梳理了目前国际上医疗费用筹措与医疗服务提供的几种主要方式,分析各自的优缺点,指出了增加公共医疗支付的必要性。文章最后提出,目前我国一些城市试行的"按病种付费"的体制,可望根据实际情况进行改进以后在更大的范围内推广。     

Case study of agri-environmental payments: The United Kingdom

The Environmentally Sensitive Areas (ESA) program, when launched in the United Kingdom (UK) in 1986, was the first agri-environmental program in the European Union (EU). This program grew to a total of 43 designated ESA schemes in the UK as a whole, 22 of which were in England. A variety of agri-environmental payments programs were created to supplement and complement the ESA schemes in years to follow. The most prominent of these in England was the Countryside Stewardship Scheme (CSS), established in 1991. The CSS was available to farmers outside the ESAs, and like the ESA program, was intended to protect valued landscapes and habitats and to improve public enjoyment of the countryside. By 2003, over 10% of England's agricultural land was enrolled in either ESA or CSS agreements. These voluntary agreements were long-term contracts (usually for 10 years) between the government and farmers to provide environmental services. Several major evaluations of the ESA program and the CSS were conducted over the years, and the results of many of those evaluations and the lessons derived are synthesized and summarized in this article. Both the ESA program and the CSS proved to be generally effective in enrolling many farmers in the entry-level contract tiers, thereby halting or slowing degradation of rural landscape and other environmental features. However, the schemes did not generally offer sufficient economic incentives to attract high levels of enrollment in the intensive farming areas. Also, the schemes were limited in their success in enrolling farmers in higher payment tiers, tiers that required more substantial changes in farming practices. The high crop and livestock-related payments received by farmers under the EU's Common Agricultural Policy (CAP) contributed to the disincentives to participate, especially in higher tiers. Following the latest (2003) reforms of the EU's CAP, England's ESA program and CSS are being replaced by a new, consolidated package of schemes that draws on lessons learned over the past 15-20 years with these two flagship programs.     

Injecting Competition into Public-Sector Return to Work: Prospects for the "Ticket to Work" Initiative

The Ticket to Work legislation (1999) introduces private-sector competition into the provision of return-to-work services for persons with disabilities who receive Disability Insurance (DI) payments. This article examines the likely effects of the Ticket to Work initiative using data from the Social Security Administration's Project NetWork experiment (1993–98). The analysis demonstrates that the efficacy of the Ticket to Work program will depend on whether the private sector replaces the vocational rehabilitative services currently provided by the public sector, or whether it expands the delivery of services—both in terms of the level and range of services provided, as well as increasing the portion of DI beneficiaries receiving services.

Optimal Price Rules,Administered Prices and Suboptimal Prevention: Evidence from a Medicare Program

Pricing methodologies in Medicare vary from one component of the system to another, often leading to conflicting incentives. Failure to recognize linkages may result in inefficient allocation of resources and higher overall costs. To motivate the analysis, I derive pricing rules for a welfare-maximizing regulator. I show that while optimal inpatient payments are standard Ramsey prices, optimal outpatient payments must incorporate net loss due to unnecessary hospitalizations, as well as supply elasticities. Ignoring this leads the myopic regulator to underprovide preventive services. The dialysis program is a useful case for empirical investigation, since payments for maintenance care are more rigidly determined than payments for related hospital care. Given constant prices, empirical analysis focuses on the effect of dialysis intensity on hospital use. Results indicate that greater dialysis intensity reduces hospital use, even at levels considered more than adequate. A simple cost-benefit calculation suggests that for every dollar of additional spending on outpatient intensity, about $2 in hospital expenditures can be saved. This suggests that the current pricing structure within aspects of the Medicare program is inefficient, underscoring the problem of regulatory myopia.     

Asymmetric information and contract design for payments for environmental services

In contractual relationships involving payments for environmental services, conservation buyers know less than landowners know about the costs of contractual compliance. Landowners in such circumstances use their private information as a source of market power to extract informational rents from conservation agents. Reducing informational rents is an important task for buyers of environmental services who wish to maximize the services obtained from their limited budgets. Reducing informational rents also mitigates concerns about the “additionality” of PES contracts because low-cost landowners are least likely to provide different levels of services in the absence of a contract. Paying low-cost landowners less thus makes resources available for contracts with higher opportunity cost landowners, who are more likely to provide substantially different levels of services in the absence of a contract. To reduce informational rents to landowners, conservation agents can take three approaches: (1) acquire information on observable landowner attributes that are correlated with compliance costs; (2) offer landowners a menu of screening contracts; and (3) allocate contracts through procurement auctions. Each approach differs in terms of its institutional, informational and technical complexity, as well as in its ability to reduce informational rents without distorting the level of environmental services provided. No single approach dominates in all environments. Current theory and empirical work provides practitioners with insights into the relative merits of each approach. However, more theoretical work and experimentation in the laboratory and the field are necessary before definitive conclusions about the superiority of one or more of these approaches can be drawn.     

Designing a payments for ecosystem services (PES) program to reduce deforestation in Tanzania: An assessment of payment approaches

Payments for ecosystem services (PES) programs aim to improve environmental outcomes by providing direct incentives to land managers for the provision of ecosystem services. Participation in PES programs is voluntary, so effective program design requires careful consideration of farmers' preferences. This study quantifies such preferences using a choice experiment. The study site is the East Usambara Mountains, Tanzania, an internationally recognized ‘biodiversity hotspot.’ We assess preferences for four payment approaches: constant and variable annual cash payments to individual farmers, a constant annual cash payment to a village fund on behalf of farmers, and an upfront manure fertilizer payment. We find that the manure fertilizer payment was statistically significant in motivating farmer participation while the group payment was non-significant. In addition, the relationship between the likelihood of participation and the stringency of conditionality is surprisingly non-linear. In a test of external validity, average willingness to accept (WTA) values are found to be similar to the average opportunity cost of maintaining land uses consistent with conservation objectives.     

Accumulation by Conservation

Following the financial crisis and its aftermath, it is clear that the inherent contradictions of capitalist accumulation have become even more intense and plunged the global economy into unprecedented turmoil and urgency. Governments, business leaders and other elite agents are frantically searching for a new, more stable mode of accumulation. Arguably the most promising is what we call ‘Accumulation by Conservation’ (AbC): a mode of accumulation that takes the negative environmental contradictions of contemporary capitalism as its departure for a newfound ‘sustainable’ model of accumulation for the future. Under slogans such as payments for environmental services, the Green Economy, and The Economics of Ecosystems and Biodiversity, public, private and non-governmental sectors seek ways to turn the non-material use of nature into capital that can simultaneously ‘save’ the environment and establish long-term modes of capital accumulation. In the paper, we conceptualise and interrogate the grand claim of AbC and argue that it should be seen as a denial of the negative environmental impacts of ‘business as usual’ capitalism. We evaluate AbC's attempt to compel nature to pay for itself and conclude by speculating whether this dynamic signals the impending end of the current global cycle of accumulation altogether.     

Selling two environmental services: In-kind payments for bird habitat and watershed protection in Los Negros, Bolivia

Marketing several environmental services from a single area can help access diverse sources of funding and make conservation a more competitive land use. In Bolivia's Los Negros valley (Department of Santa Cruz), bordering the Amboró National Park, 46 farmers are currently paid to protect 2774 ha of a watershed containing the threatened cloud-forest habitat of 11 species of migratory birds. In this payment for environmental services (PES) scheme, annual contracts prohibit tree cutting, hunting and forest clearing on enrolled lands. Farmer-landowners as service providers submit to independent yearly monitoring, and are sanctioned for non-compliance. Facilitated by a local NGO, Fundación Natura Bolivia, one service buyer is an international conservation donor (the US Fish and Wildlife Service) interested in biodiversity conservation. The second service users are downstream irrigators who likely benefit from stabilized dry-season water flows if upstream cloud forests are successfully protected. Individual irrigators have been reluctant to pay, but the Los Negros municipal government has on their behalf contributed ~ US$4500 to the scheme. The negotiated payment mode is annual quid pro quo in-kind compensations in return for forest protection. Predominantly, payments are made as “contingent project implementation”, transferring beehives supplemented by apicultural training. With regard to service provision, environment committees and education programs have increased awareness in downstream communities of the probable water-supply reduction effect of continued upstream deforestation. External donors have funded subsequent studies providing basic economic, hydrological and biodiversity data, and covered PES start-up (~ US$40,000) and running transaction costs (~ US$3000 per year over the last three years). The greatest challenges in the development of the PES mechanism have been the slow process of building trust between service buyers and providers, and in achieving clear service-provision additionality.     

REDD+ as Result‐based Aid: General Lessons and Bilateral Agreements of Norway

The initiative known as Reducing Emissions from Deforestation and Forest Degradation (REDD+) officially became part of the international climate agenda in 2007. At that time, REDD+ was an idea regarding payment to countries (and possibly also projects) for reducing emission from forests, with funding primarily from carbon markets. The initiative has since become multi‐objective in nature; the policy focus has changed from a payments for environmental services (PES) approach to broader policies, and international funding primarily originates from development aid budgets. This “aidification” of REDD+ has made the program similar to previous efforts using conditional or results‐based aid (RBA). However, the experience of RBA in other sectors has scarcely been addressed in the REDD+ debate. The alleged advantages of RBA are poorly backed by empirical research. This paper reviews the primary challenges in designing and implementing a system of RBA, namely, donor spending pressure, performance criteria, reference levels, risk sharing, and funding credibility. It then reviews the four partially performance‐based, bilateral REDD+ agreements that Norway has entered with Tanzania, Brazil, Guyana, and Indonesia. These agreements and the aid experience provide valuable lessons for the design and implementation of future REDD+ mechanisms.     

构建我国海洋生态补偿法律机制的实然性分析

生态补偿制度在弥补市场失灵、解决外部化方面,为不同主体提供环境服务保障了现实的经济或财政刺激。这一制度在不同的适用领域均受到了广泛关注。尽管生态补偿制度并不适用于所有的环境保护领域,但在海洋环境保护的某些特殊领域的作用却是独一无二的。生态补偿制度在海洋生态环境保护中刚刚起步,且在实践中陷入了困境。海洋生态补偿在我国海洋保护的现实性与可行性究竟如何?这就需要结合我国海洋资源利用状况、海洋经济发展态势、海域使用权制度、海洋环境保护制度、减少因生态保护造成的贫困等进行全面论证,才能确立海洋生态补偿的可行性与现实性。     

THE TREATMENT OF INTEREST AND NET RENTS IN THE NATIONAL ACCOUNTS FRAMEWORK1

The contention in this paper is that the present method of treating interest and net rents as transfers rather than as payments for services provided creates problems in the measurement of production by industry and that the difficulties encountered in explaining the treatment of interest items in the different tables of the National Accounts are even more apparent when one views the National Accounts framework as an integrated reflection of economic reality. It is argued that the lending of money arises from the stretching out of the production and consumption process, and the interest charges constitute a charge for the administrative services and risk involved. This is somewhat analagous to the charges for hiring out real goods and services. A similar case is made for the treatment of rents with the exception of imputed net rent where it is contended that economic risk is incurred only when production is undertaken for sale and that there should be no entrepreneurial return where the production is for the use of the owner-producer. It is suggested that an alternative treatment of interest and rents as payments for services is more realistic. Its adoption in the National Accounts would eliminate the need for imputations now made to account for the production of financial intermediaries, as well as the unconvincing explanations put forward for the present treatment of interest on consumer and public debt. Finally, it would serve to integrate the production accounts with the financial flows and the related financial structure.
