Against the backdrop of a community-based fishery management institution called kadakkodi, this paper addresses the question of how institutions evolve, innovate, or disintegrate. It explains how institutional evolution is determined by factors like relative resource endowment, technology, cultural endowment, and inherited institutional structures. The strength of such informal institutions in facilitating effective resource management admitted, the paper argues that in the wake of increasing resource-related, technological, cultural and institutional heterogeneities, they may fail to perform and hence are no panacea to the problems of resource management. Such predicaments may call for complementary formal institutions whose supply, however, would depend on the cost of collective action.

The terminator gene can render seeds sterile, so forcing farmers to purchase fresh seed every year. It is a technological solution to the problem of market failure that could increase the appropriability of R&D investment more effectively than intellectual property rights legislation or patents. This paper shows that appropriability should be more than tripled and that this leads to greater private R&D investment, which may be expected to double or triple. This would bring open-pollinating varieties into line with F1 hybrids, for which seed cannot be saved. In turn, the increased investment should raise yield increases to levels similar to those for hybrid crops. Thus, there are benefits to set against the possible ecological and environmental costs and the clear distributional and social consequences. The paper discusses the way the seed market is developing, the possible impacts, especially from a developing country viewpoint, and considers the policy changes that are needed.

This paper examines the dynamic effects of forest conservation measures. Both short-term and long-term impacts on timber markets are studied using a Finnish example. Forest conservation is interpreted as an exogenous negative shock in the standing timber growth owned by private forest owners, and its effects are retrieved through an impulse response analysis based on a dynamic demand–supply and timber stock model. The results show that timber markets are influenced by forest conservation. The conservation of forest assets reduces traded quantities and increases timber prices. These effects are of the same relative magnitude, thus leaving the annual timber-selling income of private forest owners unchanged. The results suggest that some of the negative short-run impacts of conservation on commercial timber stock will be compensated in the long run by intensified use of the remaining stock. This may to some extent reduce the ecological usefulness of the conservation policies. While the timber markets converge in the long run towards a new post-conservation state the short-term interruptions suggest that caution should be used in establishing set-asides in privately owned forestland.

This paper evaluates policies for addressing forest degradation in developing country hill areas, where agriculture is the major activity and villagers depend on forests for important economic inputs. Population growth, poverty, and open access probably explain most 'overuse' in such areas, but these are very difficult, long-term problems. The paper argues that under such conditions interim demand-side policies should be seriously considered, but the case is also made that the set of feasible instruments is quite small. Focusing on the case of Nepal, two instruments for reducing fuelwood demand – promotion of more efficient, wood-burning cookstoves and policies that reduce the prices of alternative fuels (e.g., through subsidies) – are evaluated. Using a simple analytical model and results from two household surveys conducted in Nepal, it is concluded that promoting improved stoves is a much more efficient and equitable instrument than, for example, subsidizing the major alternative fuel, which is kerosene. The cost of fuelwood saved using improved stoves is predicted to be a very low $2.77 per metric ton.

The authors use dynamic lab-in-the-field common pool resource experiments to investigate the role of two forms of democracy on the cooperation of forest users in Ethiopia. In this experimental setup, participants can either directly select a rule (direct democracy) or elect a leader who decides on the introduction of rules (representative democracy). These two treatments are compared with the imposition of rules and imposition of leaders. It is found that both endogenous leaders elected by the community members and endogenous rules selected by the direct involvement of the participants are more effective in promoting cooperation among the community members compared to exogenous leadership, exogenous rule imposition and the baseline scenario without any of these modifications. However, no significant difference is found between representative democracy in the election of leadership and direct democracy in the selection of rules. Leadership characteristics and behavior are further analyzed. The results underline the importance of democratic procedures.

A revenue-sharing arrangement is under consideration between the USA and Western and Central Pacific Island Parties. When the ex-vessel price for cannery-grade skipjack tuna is above a minimum price, Pacific Island Parties would share in the increased revenue. This arrangement would provide economic incentives to these island nations to control fishing capacity and thereby increase revenues and economic rents. This potential arrangement raises the issue of which market and species prices to use as a benchmark, Bangkok or Pago-Pago; American Samoa and skipjack or yellowfin tuna. This paper, through a time series analysis of spatial price linkages, finds price leadership for skipjack in Bangkok. Macroeconomic and regional economic implications of enhanced price stability and higher revenues in the region are also discussed.

We consider the redistributive effects of privatizing a resource previously exploited under free access. We assume that illegal extraction is punished but that the sanction is bounded by individuals' wealth. First, we show that a segment of intermediate-wealth individuals is the most adversely affected from the regime change, while the poorest segment is not only less severely affected, but may actually gain from it. Next, we show how the authorities may prefer to choose an intermediate enforcement level in order to maximize the political acceptability of the regime switch among the local community.

Fuelwood scarcity creates a widespread environmental problem that places a major burden on women and children in the rural areas of developing countries. Consequently, many governments, donors and non-governmental organizations have encouraged on-farm fuelwood production and agroforestry practices. Whether, however, fuelwood from different sources can be easily substituted is an important empirical question as the degree of substitutability can depend on local markets and households' resource endowments and incomes. In this paper, we examine the substitution between three fuelwood sources among rural households in western Kenya: fuelwood collected off-farm, fuelwood produced on-farm, and that which is purchased. Using household-specific shadow prices for fuelwood and male and female wages, we find that strict gender divisions in household labor result in limited substitution between fuelwood sources. Among the implications are that programs and policies promoting agroforestry will have limited success without first addressing the structural differences in labor markets.

A framework is provided for structuring programs aimed at reducing emissions from deforestation and forest degradation (REDD). Crediting reference levels and the coordination among different implementing entities at multiple geographic scales are discussed. A crediting reference level has an error component if it differs from the business-as-usual (BAU) without REDD. Both the BAU emissions and the impact of REDD actions are uncertain, implying that participating in REDD entails stakeholder risk, the distribution of which depends on REDD program design. To categorize REDD architectures we define scale-neutrality whereby, for a given REDD design, crediting relative to the reference level at a given scale is not affected by errors in reference levels at scales below it. Sufficient conditions are derived for scale-neutrality to hold. A Brazilian Amazon example is provided, comparing potential REDD architectures, and highlighting how a cap-and-trade approach may match the environmental outcome obtainable with perfect foresight of the BAU emissions.

Reliance of modern economic activities on the use of energy, most of which still comes from non-renewable sources, provokes concerns regarding the most efficient utilization of energy inputs in production. While most theory expects directed technological change to be biased towards the non-renewable input, there is rare macro-level evidence that technological change is actually biased towards energy rather than other main inputs. To fill this gap, we apply stochastic frontier analysis to country data regarding output produced with capital, labor and energy, and estimate a set of indicators for technological change. Findings show that technological change is biased the most towards energy in general. In particular, although different groups of countries exhibit various patterns, there is strong evidence that technological change favors energy more than labor. This is in line with the theoretical expectation that technological change ought to be biased towards the non-renewable input rather than the renewable ones.

Using data from the World Value Survey for the period 1981–2007, this paper shows that the level of trust is positively linked to the willingness to contribute to environmental goods in selected African countries. The results are robust to possible errors in measuring trust, to the presence of various controls, and the potential endogeneity bias. These findings complement and extend the existing literature in the sense that they provide evidence on the importance of trust in improving the collective management of natural resources in Africa.

This paper develops an approach to assess the political risk associated with implementation of institutional reforms in the water sector, while providing insights into the interrelationship of institutional arrangements, power structure, and policy outcome. The analytical approach consists of a two-tier process to assess the institutional feasibility of reform implementation. The first tier is a structured analysis of power distribution among the power groups interested in the outcome of the reform. The second tier is a Delphi process, reflecting the opinions of experts. The approach was applied to the case of the National Drainage Program Project (NDP) in Pakistan, currently in the early stages of implementation. Several hypotheses regarding likely progress were tested, using the feedback provided by a panel of experts in the Delphi process.

International conservation investments are often made in the form of subsidies to purportedly eco-friendly enterprises rather than as payments conditional on habitat protection. Previous research demonstrated that direct payments for habitat protection are more cost effective than indirect subsidies for the acquisition of com-plementary inputs used in eco-friendly enterprises. In contrast to this earlier research, we assume in this paper that an ‘eco-entrepreneur’ may have market power. Market power is shown to compound the advantage of direct payments. Through a simple numerical example, we show that subsidies intended to achieve habitat conservation by encouraging the acquisition of complementary inputs can be spectacularly inefficient. In some cases it would be cheaper simply to buy the land outright. In other plausible cases, the indirect subsidy approach would simply be unable to achieve habitat conservation objectives no matter how much funding were available.

Cash-constrained wildlife departments must increasingly look towards revenue-generating activities such as sales of permits for hunting common species combined with fines for those caught with rare species. Pertinent to west Africa, an optimal enforcement model demonstrates the conditions under which a department with neither external budget nor tourism revenue can fully protect a rare species, and the impact on other species and local hunters' livelihoods. The department's effectiveness is shown to depend critically on the extent to which hunters can discriminate among different species. Improvements in hunting technology selectivity are therefore a substitute for increased enforcement spending.

Efforts to identify the determinants of environmental policy success have largely been anecdotal and case study based. This article seeks to shift environmental policy analysis on to more analytically rigorous and empirical foundations. Using statistical analysis, we identify a set of factors that drive environmental performance as measured by levels of urban particulates, sulfur dioxide, and energy use per unit of GDP. Although the data are imperfect and causal linkages cannot be definitively established, the statistical analysis presented suggests that environmental results vary not only with income levels as suggested by the environmental Kuznet's curve literature but also with both the sophistication of a nation's regulatory regime and perhaps more notably, its broader economic and social circumstances.

This paper focuses on the interactions between local communities having at least some degree of informal claims over natural resources and firms interested in commercially exploiting such resources, explicitly allowing for interventions by third parties interested in community welfare and environmental outcomes. Integrating conflict and bargaining theories, we develop a bargaining model with endogenous inside and outside options, in which the feasibility and outcomes of a potential bargaining game depend on the unraveling of a conflict stage and vice versa. The model implies that, contrary to the conventional bargaining model, distribution and efficiency cease to be separable. We show that certain third-party interventions in the bargaining process may have unexpected and counterproductive effects.

In order to significantly reduce global carbon emissions, it is necessary also to control CO2 emissions in fast growing emerging economies such as India. The question is how the Indian economy would be affected by including the country in an international climate regime. In this analysis we soft-link a global and a single-country computable general equilibrium model in order to be able to capture distributional issues as well as international repercussions. We analyze different options of transferring revenues from domestic carbon taxes and international transfers to different household types and the effects of different assumptions on exchange rates on transfer payments. Our results show (i) that welfare effects can differ significantly for different household types, which is generally ignored in analyses with global models, and (ii) that these effects are significantly influenced by international price repercussions and by accounting for transfers from international permit sales which is generally ignored in single-country models.

This paper studies the effects of drought shocks in a vulnerable environment – the Brazilian Semi-Arid. We analyze the impact of drought shocks, measured as deviations from long-run historical averages, on agricultural outcomes in a region that suffers recurrently from drought. After controlling for municipality and year fixed effects, we use weather shocks to exactly identify outcomes. Our benchmark results show substantial effects on the loss of crop area and on the value of agricultural output, as well as on crop yields. As we investigate distributional effects, our results show that crops related to familiar agriculture suffer more from drought shocks. We follow our investigation by testing heterogeneity effects and show that adequate water provision and maintenance of forest cover help in reducing the impact of drought shocks.

This paper investigates how openness resulting from the adoption of the open-door policy influences air quality in urban China. City-level information is used to minimise the impacts of data inconsistency and data measurement problems. The intensity of international trade is used as a proxy for openness to examine how freer trade influences urban air quality. Several alternative measures of openness are adopted to investigate how different forms of openness can influence urban air quality. Our findings show that technique effects are the key to reversing the degradation of urban air quality and that openness is not necessarily a problem for urban air quality in China.

The current paper offers a new explanation of the emergence of multiple equilibria, for which the high (low) income equilibrium is associated with high (low) environmental quality. This new explanation rests on endogenous technological choice in the presence of emission taxes – an idea whose foundations find strong support from existing empirical evidence. Thus, the interactions between environmental policy and technology choice, within a framework that accounts for the health effects of pollution, may suggest a possible mechanism behind some of the observed differences in income, life expectancy and environmental quality among countries.
