Ecomarkets for conservation and sustainable development in the coastal zone

Because conventional markets value only certain goods or services in the ocean (e.g. fish), other services provided by coastal and marine ecosystems that are not priced, paid for, or stewarded tend to become degraded. In fact, the very capacity of an ecosystem to produce a valued good or service is often reduced because conventional markets value only certain goods and services, rather than the productive capacity. Coastal socio‐ecosystems are particularly susceptible to these market failures due to the lack of clear property rights, strong dependence on resource extraction, and other factors. Conservation strategies aimed at protecting unvalued coastal ecosystem services through regulation or spatial management (e.g. Marine Protected Areas) can be effective but often result in lost revenue and adverse social impacts, which, in turn, create conflict and opposition. Here, we describe ‘ecomarkets’ – markets and financial tools – that could, under the right conditions, generate value for broad portfolios of coastal ecosystem services while maintaining ecosystem structure and function by addressing the unique problems of the coastal zone, including the lack of clear management and exclusion rights. Just as coastal tenure and catch‐share systems generate meaningful conservation and economic outcomes, it is possible to imagine other market mechanisms that do the same with respect to a variety of other coastal ecosystem goods and services. Rather than solely relying on extracting goods, these approaches could allow communities to diversify ecosystem uses and focus on long‐term stewardship and conservation, while meeting development, food security, and human welfare goals. The creation of ecomarkets will be difficult in many cases, because rights and responsibilities must be devolved, new social contracts will be required, accountability systems must be created and enforced, and long‐term patterns of behaviour must change. We argue that efforts to overcome these obstacles are justified, because these deep changes will strongly complement policies and tools such as Marine Protected Areas, coastal spatial management, and regulation, thereby helping to bring coastal conservation to scale.     

Demand and Dematerialization Impacts of Second-Hand Markets

The potential for second-hand markets to reduce demand for new goods is investigated. Using a variant of an economic model originally developed by Anderson and Ginsburgh, the physical implications for material use are explored. The second-hand market grows if transaction costs decrease or if product lifetime increases. In this model, growth of the secondhand market reduces demand for new goods if there are waste used goods that can be brought into the market. But if there is not a ready supply of waste used goods, growth of the second-hand market can increase demand for new goods, thereby increasing material consumption. Moreover, even when second-hand sales reduce demand for new goods, it is typically not on a one-for-one basis. The extent to which the purchase of used goods replaces the purchase of new goods is shown to be an explicit function of the relative value provided by used versus new goods.     

Recombinant plant-derived pharmaceutical proteins: current technical and economic bottlenecks

Molecular pharming is a cost-effective platform for the production of recombinant proteins in plants. Although the biopharmaceutical industry still relies on a small number of standardized fermentation-based technologies for the production of recombinant proteins there is now a greater awareness of the advantages of molecular pharming particularly in niche markets. Here we discuss some of the technical, economic and regulatory barriers that constrain the clinical development and commercialization of plant-derived pharmaceutical proteins. We also discuss strategies to increase productivity and product quality/homogeneity. The advantages of whole plants should be welcomed by the industry because this will help to reduce the cost of goods and therefore expand the biopharmaceutical market into untapped sectors.     

Commodification and Human Interests

In Markets Without Limits and a series of related papers, Jason Brennan and Peter Jaworski argue that it is morally permissible to buy and sell anything that it is morally permissible to possess and exchange outside of the market. Accordingly, we should (Brennan and Jaworski argue) open markets in “contested commodities” including blood, gametes, surrogacy services, and transplantable organs. This paper clarifies some important aspects of the case for market boundaries and in so doing shows why there are in fact moral limits to the market. I argue that the case for restricting the scope of the market does not (as Brennan and Jaworski assume) turn on the idea that some things are constitutively non-market goods; it turns instead on the idea that treating some things according to market norms would threaten the realization of particular kinds of human interests.     

Conserving global biological diversity by encouraging alternative development paths: can development coexist with diversity?

The conservation of biological diversity concerns the management of the development process, not only at the national but also at the global level. Individual countries have made their development choices independently but relatedly, too often following the precise form of the choices of other countries preceding them in the development process. Development via imitation is pursuing the form, rather than the substance of a successful development strategy. Countries should instead be developing upon a base of assets that provides them with a relatively unique set of goods and services to place upon global markets. When the first countries developed, this criterion indicated that they should convert their countries to new forms of production; when the last countries are developing, relatively unique goods and services flow from their lands as they stand. What is required is the development of global institutions that encourage countries to see that their best development opportunities lie down these alternative development pathways, based upon their already-existing but relatively unique national assets.     

Ethnic divisions and public goods provision,revisited

A considerable amount of recent work in political science and economics builds from the hypothesis that ethnic heterogeneity leads to poor provision of public goods, a key component of poor governance. Much of this work cites Alesina, Baqir and Easterly as providing empirical proof. This paper argues that the findings of this article have been significantly overstated. Through a simple re-analysis of the data, it shows that ethnic diversity does not straightforwardly undermine public goods provision. Rather, at least in these data, the relationship is mixed for different public goods: ethnic diversity is related to lower provision of some public goods and to higher provision of others. In some cases, there is no clear relationship. The differences between the findings presented here and those of the original article are arguably subtle, but are worth noting because of Alesina, et al.'s important contribution to the literature.     

On the Attractiveness of Product Recovery: The Forces that Shape Reverse Markets

Product recovery is a major contributor for implementing sustainable business practices. Within such operations, which are either driven by legislation or economic rationales, practitioners face strategic issues concerning reverse market entry and positioning. Although the complexity of acting on reverse markets is widely acknowledged, a comprehensive framework to facilitate decision making in this area is lacking. In an attempt to fill that gap, we develop a model that supports original equipment manufacturers’ (OEMs’) assessment of the attractiveness of reverse markets. We identify, from a comprehensive literature analysis, in‐depth interviews, and engagement with a dozen companies from different countries, factors that influence key characteristics of reverse markets, and consolidate this lengthy list into a comprehensive model intuitively applicable to business practice. The model combines five forces that drive reverse markets: access to recoverable products; threat of independent recovery companies’ (IRCs’) market entry; rivalry for recoverable products; adverse effects on core business; and remarketing opportunities. We propose for each a set of attributes that influences its power and direction. To demonstrate the efficacy of the model, we apply it in two industry settings: recovery of white goods in the United Kingdom and paper recycling in Germany. The present research enables OEMs to understand the structure and forces that drive reverse markets, identify levers to influence those markets, anticipate market developments, and formulate resilient strategies for product recovery.     

On market forces and human evolution

This paper studies how an institution such as markets affects the evolution of mankind. My key point is that the forces of natural selection are made weaker because trade allows people to specialize in those activities where they are strong, and to offset their weaknesses by purchasing adequate goods on the market. Absent trade, people must allocate their time among all the activities necessary for their fitness. A productivity advantage in any given dimension will increase survival probability, so that in the long run natural selection makes sure that population is entirely made of individuals with the strongest alleles at all loci. Under trade, there exist long-run equilibria where weaker individuals are able to achieve the same survival potential as the fittest, by specializing in activities where they are not at a disadvantage, and purchasing goods that are substitute for activities for which they are weak.     

A public goods approach to major evolutionary innovations

The history of life is marked by a small number of major transitions, whether viewed from a genetic, ecological, or geological perspective. Specialists from various disciplines have focused on the packaging of information to generate new evolutionary individuals, on the expansion of ecological opportunity, or the abiotic drivers of environmental change to which organisms respond as the major drivers of these episodes. But the critical issue for understanding these major evolutionary transitions (METs) lies in the interactions between environmental, ecologic, and genetic change. Here, I propose that public goods may serve as one currency of such interactions: biological products that are non‐excludable and non‐rivalrous. Such biological public goods may be involved in either the generation of new evolutionary variation, as with genetic sequences that are easily transferred between different microbial lineages, or in the construction of new ecological niches, as with the progressive oxygenation of the oceans and atmosphere. Attention to public goods emphasizes the processes by which organisms actively construct their own evolutionary opportunities. Such public goods may have facilitated some METs.     

Coping Strategies in Livestock-dependent Households in East and Southern Africa: A Synthesis of Four Case Studies

Integrated assessment seeks to combine models of the ecological as well as the social system to allow different scenarios to be tested in terms of their likely impacts on ecological functioning and household well-being. We outline such work undertaken in four case studies in East and southern Africa: pastoralist communities in northern Tanzania, agro-pastoralists in southern Kenya, communal and commercial ranchers in South Africa, and mixed crop-livestock farmers in western Kenya. Results from these case studies are synthesised to test the hypothesis that households’ capacity to adapt in the face of increasing external stresses is governed by flexibility in livelihood options. The results support this hypothesis. There is considerable variation in how households in these places cope with external stresses. Options include intensification, diversification, and increasing off-farm economic activities, and these depend on household objectives and attitudes as well as on access to natural resources, inputs and output markets. The results also indicate that generally it is the poorer households that can gain the most from implementing such options for coping and managing risk. Quantifying likely household and ecosystem impacts of different options is a crucial step in targeting appropriate technology, policy and adaptation interventions in the face of considerable system changes. We conclude with some research needs to improve integrated assessment tools that may allow us to represent more realistically the highly complex decision-making milieu of householders in sub-Saharan Africa who are dependent on ecosystem goods and services for a large part of their livelihoods.     

Personalised food: how personal is it?

Consumer goods became increasingly personalised, particularly during the last half of the 20th century. Foods and food products have been added a new flavour in this consumer trends with increasingly personalised values of convenience, cost, packaging, and taste. Now functional food industry is ready to take its next venture in a relatively new domain personalising health. Whether the goal of matching foods to individual genotypes to improve the health of those individuals can be attained, and personalised nutrigenomic foods enter the world’s food markets, depends on numerous hurdles being overcome: some scientific in nature, some technical and others related to consumer, market or ethical issues. Public adoption of new technologies is an important determinant for their success. Many of the drivers behind the trend in personalisation of food are now known, particularly ethical, legal and social issues (ELSI) are the major drivers. Future development in the field of nutrigenomics undoubtedly will place its seemingly huge potential in better perspective. Thus, the agriculture and food enterprise has an extraordinary opportunity to link individuals with foods that are personalised for their health.     

Experimental evidence that partner choice is a driving force in the payoff distribution among cooperators or mutualists: the cleaner fish case

Supply and demand largely determine the price of goods on human markets. It has been proposed that in animals, similar forces influence the payoff distribution between trading partners in sexual selection, intraspecific cooperation and interspecific mutualism. Here we present the first experimental evidence supporting biological market theory in a study on cleaner fish, Labroides dimidiatus . Cleaners interact with two classes of clients: choosy client species with access to several cleaners usually do not queue for service and do not return if ignored, while resident client species with access to only one cleaning station do queue or return. We used plexiglas plates with equal amounts of food to simulate these behaviours of the two client classes. Cleaners soon inspected 'choosy' plates before 'resident' plates. This supports previous field observations that suggest that client species with access to several cleaners exert choice to receive better (immediate) service.     

滨海湿地生态系统服务及其价值评估研究进展

滨海湿地是介于海陆之间的过渡地带,具有丰富的生物多样性和很高的生产力,能为人类提供诸多生态系统服务,但它又是对人类活动极为敏感的生态脆弱区。沿海经济的发展使湿地资源的有限性与人类需求的无限性之间的矛盾日益突出,导致湿地多样性丧失、服务功能退化等。在阐述滨海湿地特征及其服务产生机理的基础上,介绍了运用经济学方法对生态系统服务进行评价的进展,分析了各方法的优缺点及应用情况,最后对滨海湿地生态系统服务价值评估中存在的问题进行了总结归纳,评估所面临的困难一方面来自生态系统本身的复杂性;另一方面来自经济学方法的局限性。因此今后的研究应从生态系统服务的形成机制入手,注重生态学及经济学理论的结合,改善评估方法,提高评估结果的有效性和可信度,为湿地资源管理及生态补偿机制制定提供有力支持。     

Reputation-based partner choice is an effective alternative to indirect reciprocity in solving social dilemmas

When group interests clash with individual ones, maintaining cooperation poses a problem. However, cooperation can be facilitated by introducing reputational incentives. Through indirect reciprocity, people who cooperate in a social dilemma are more likely to receive cooperative acts from others. Another mechanism that enhances group cooperation is reputation-based partner choice, or competitive altruism. According to this framework, cooperators benefit via increased access to cooperative partners. Our study compared the effectiveness of indirect reciprocity and competitive altruism in re-establishing cooperation after the typical decline found during repeated public goods games. Twenty groups of four participants first played a series of public goods games, which confirmed the expected decline. Subsequently, public goods games were alternated with either indirect reciprocity games (in which participants had an opportunity to give to another individual from whom they would never receive a direct return) or competitive altruism games (in which they could choose partners for directly reciprocal interactions). We found that public goods game contributions increased when interspersed with competitive altruism games; they were also higher than in public goods games interspersed with indirect reciprocity games. Investing in reputation by increasing contributions to public goods was a profitable strategy in that it increased returns in subsequent competitive altruism and indirect reciprocity games. There was also some evidence that these returns were greater under competitive altruism than indirect reciprocity. Our findings indicate that strategic reputation building through competitive altruism provides an effective alternative to indirect reciprocity as a means for restoring cooperation in social dilemmas.     

"Our Beer": Ethnographic Brands in Postsocialist Georgia

Although Georgia is known for its wines, industrial production of beer far outstrips industrial wine production for local markets: wine consumption occurs in ritual contexts in which new wine, typically purchased from peasant producers, is preferred; bottled, aged wines are primarily for exports. Beer, therefore, is a key area in which industrial production for indigenous consumers has been elaborated. Such goods are packaged and presented as being both ecologically "pure" and following "traditional" methods, often referencing "ethnographic" materials about traditional life in brand images, even as they proclaim their reliance on Western technologies.     

HIV international clinical research: exploitation and risk

This paper aims to show that to reduce the level of exploitation present in (some) international clinical trials, research sponsors must aim to provide both an ex-ante expected gain in utility and a fair ex-post distribution of benefits for research subjects. I suggest the following principles of fair risk distribution in international research as the basis of a normative definition of fairness: (a) Persons should not be forced (by circumstance) to gamble in order to achieve or protect basic goods; (b) In cases where one party is gambling with basic goods and the other party is not, the distribution of benefits and burdens must be arranged so that they are of greatest benefit to the worst off; (c) In relationships where one party is gambling for basic goods and the other party is not, the party gambling for basic goods must be assured of some guaranteed benefits in addition to the chance of getting some practical benefits. These principles are applied to the case of HIV international research. I conclude that the research (as described) is mutually advantageous but still exploitative because the distribution of surplus benefits is unfair. It is unfair because research subjects are gambling with and for basic goods but they are not assured of a fair ex-post distribution of benefits. Principles (b) and (c) are not satisfied. Research participants are not accorded enough guaranteed benefits to outweigh the risks they undertake.     

Reputation and Competition in a Hidden Action Model

The economics models of reputation and quality in markets can be classified in three categories. (i) Pure hidden action, where only one type of seller is present who can provide goods of different quality. (ii) Pure hidden information, where sellers of different types have no control over product quality. (iii) Mixed frameworks, which include both hidden action and hidden information. In this paper we develop a pure hidden action model of reputation and Bertrand competition, where consumers and firms interact repeatedly in a market with free entry. The price of the good produced by the firms is contractible, whilst the quality is noncontractible, hence it is promised by the firms when a contract is signed. Consumers infer future quality from all available information, i.e., both from what they know about past quality and from current prices. According to early contributions, competition should make reputation unable to induce the production of high-quality goods. We provide a simple solution to this problem by showing that high quality levels are sustained as an outcome of a stationary symmetric equilibrium.     

Subsistence strategies of an indigenous minority in the Philippines: Nonwood forest product use by the Tagbanua of Narra, Palawan

Indigenous people, such as the Tagbanua of Palawan Island in the Philippines, are often considered to be experienced and responsible users of natural resources. The Tagbanua have traditionally been involved in the collection of nonwood forest products (NWFPs) both for trade and for subsistence purposes. The proximity of many Tagbanua communities to the forest allows them easy access to NWFPs, although various restrictions, such as distance from markets, legal land issues, and lack of formal education, prevent them from receiving more favorable earnings from the sale of NWFPs. Similarly, increasing access to manufactured products also lessens dependence on NWFPs for food, medicine, and housing purposes, although small incomes prevent extensive conversion to the use of purchased goods. The knowledge and current subsistence-level use of NWFPs by the Tagbanua from the settlement of Boong are described and discussed.     

Ecological considerations for using dipterocarps for restoration of lowland rainforest in Southeast Asia

The lowland dipterocarp forests of Southeast Asia support a substantial proportion of the world’s biodiversity. They are of considerable environmental and economic value at the local, regional and global scale, providing many goods and services to a growing population. The forests of this region are among the fastest disappearing in the world and restoration is urgently required. This paper provides a review of the ecological constraints to restoration of lowland dipterocarp forest in Southeast Asia. It focuses on the production of planting stock, the significance of site-species matching and post-planting site maintenance. It identifies gaps in our knowledge and highlights priority areas of research. Adopting a long-term view is essential for restoring as well as conserving the dipterocarp forests of Southeast Asia. An immediate strategy for the conservation and management of dwindling genetic resources of these important timber species is essential. This will provide the foundations for sourcing seed and production of planting material for longer term restoration. The importance of species-site matching, mycorrhizal fungi and post-planting maintenance for restoration are apparent. Financing is a major limiting factor to dipterocarp forest restoration. Trading in carbon, private finance and environmental markets afford considerable opportunities for restoring these forests providing their total value is recognised. Despite the wealth of ecological knowledge we already have for scientifically-informed forest restoration, without the backing of governments and corporate stakeholders, forest restoration will not gain the urgently required momentum.     

生态系统服务功能体系框架整合的探讨

有关生态系统服务功能的价值估算的文献越来越多。然而,这些数据特别分散,且缺乏统一的尺度与估算标准,从而导致生态经济分析不具有可比性。鉴于这种情况,本文试图建立生态系统服务功能综合集成体系框架,对生态系统功能、服务和商品及其价值估算严谨一致地提出了基本概念框架,将生态系统服务功能划分为4大类23亚类,分别对应于经济、生态和社会文化价值,并以矩阵和清单的形式在这些生态系统服务功能与各种估算方法之间建立了对应关系。
