We examine the implications of migration and insecure property rights to land use and deforestation in tropical frontier forests. Three forms of property rights risks are introduced to basic land-use forms. Illegal logging risk is associated with forest plantations, a land expropriation risk affects land in agriculture and plantation forestry, and illegal logging risks threaten native forest land. Public and private landowners can reduce these risks by employing costly enforcement effort. We show how that migration, expropriation, and illegal logging risks lead to deforestation by promoting agricultural expansion, and illegal logging. Higher public enforcement reduces illegal logging, but higher private enforcement may or may not reduce deforestation depending on migration pressures. Higher timber prices have an ambiguous effect on deforestation, but an increasing value of non-timber benefits decreases or leaves deforestation unchanged depending on the incentive structures of illegal loggers.

This paper offers a theory of the environmental Kuznets curve (EKC) based on the scarcity of capital relative to environmental quality. In a unified treatment of both market and transition economies of the former Soviet Bloc, we characterize a dynamic economy subject to two sources of market failure: a pollution externality and a pure public good ‘environmental quality’. We derive a policy rule to implement the social optimum in market and transition economies and show how, in general, a pollution tax or tradable permits can only implement the social optimum if accompanied by other taxes on consumption or profits.

Many poor countries remain trapped in a cycle of poverty and environmental degradation. Understanding how people react to existing and proposed solutions most likely can be improved using the methods of experimental economics. Experiments provide researchers a method to test theory, look for patterns of behavior, testbed economic institutions and incentives, and to educate people. Herein we explore how experimental economics has been used and could be used to help guide decision making to increase prosperity without overexploiting the resource base and environmental assets needed for basic survival.

The demand for environmental quality is often presumed to be low in developing countries due to poverty. Less attention has been paid to the possibility that lack of awareness about adverse health effects of environmental pollution could also keep the demand low. We use a household survey from urban India to estimate the effects of schooling, exposure to mass media, and other measures of awareness on home water purification. We find that these measures of awareness have statistically significant effects on home purification and, therefore, on willingness to pay. These effects are similar in magnitude to the wealth effects. Average costs of different home purification methods are used to generate partial estimates of willingness to pay for better drinking water quality.

This study revisits and updates a 1999 economy-wide analysis predicting that increases in tourism would result in rapid economic as well as demographic growth on the Galapagos Islands. The following six years witnessed sharp growth in tourism; a restructuring of tourism around larger cruise ships and new, larger hotels; and rapid population growth. Our findings indicate that total income (that is, the gross domestic product) of the Galapagos increased by an estimated 78 per cent between 1999 and 2005, making the Galapagos economy among the fastest growing in the world. Tourism continued to be far and away the major driver of economic growth. Nevertheless, population growth via new migration to the islands nearly erased the effect of economic growth on per-capita household income. These findings raise questions about the compatibility of ecotourism and conservation in this unique ecological setting.

Game theory has been useful as an analytical framework for assessing environmental and resource regulations and policies. The papers in this volume provide the latest methodological and applied works in game theory to a wide range of natural and environmental resource problems such as fishing, grazing, pollution, climate change, water allocation, and stochastic production processes. The findings in the papers suggest that game theory is an effective tool for the analysis of the efficient use of shared natural resources; it can be used to identify stable agreements between parties to a resource conflict, and show how non-cooperation over global public goods/bads has a high social cost tag.

A lack of information on environmental protection values, especially non-market values, has contributed to wetland degradation in the Mekong River Delta. To fill this information gap, this study uses choice modelling to estimate the biodiversity protection values of Tram Chim National Park, a typical wetland ecosystem of the Delta. The estimated net social benefit of a proposed protection program ranges from USD0.52 million to USD1.84 million. This suggests that the program's implementation would improve social welfare. Some choice modelling issues, including the use of focus groups, aspects of questionnaire designs, and different survey modes, are discussed in the context of a developing country application.

The Pollution Haven Hypothesis (PHH) states that with weak environmental policies a country can create comparative advantage in the polluting sector. This paper formulates a 3-good-3-factor model where the abatement input is a pure intermediate good. In our model, the PHH as well as the neoclassical trade theorems are valid only when environmental policies are distribution neutral. Inspired by the US Clean Air Act, we develop and estimate a dynamic panel model. We find that US environmental policies are consistent with distribution neutrality. Our results indicate that lowering abatement standards in all industries is the only way the US can become a pollution haven. In the context of our model, the PHH has damaging implications for the world environment.

This paper is not concerned with advances in game theory. Rather, the paper is concerned with the relevance, if any, of game theory to a major resource management issue, namely the management of internationally shared fishery resources. It is argued that the economics of the management of such resources cannot, in fact, be understood, other than through the lens of game theory. The paper discusses several elementary game theory concepts that are of utmost policy relevance, but which are, as of yet, poorly understood by most policy makers. The paper does, in addition, discuss a key policy problem in the management of shared fishery resources that demands a game-theoretic analysis. The required analysis, however, has yet to be developed.

This paper examines the double dividend hypothesis in the presence of labour income uncertainty. Empirical evidence shows that uncertainty over labour income is particularly significant in developing, while not negligible in developed countries. Under uncertainty, and assuming incomplete capital markets, the tax system plays a role in providing social insurance, and a green tax reform influences its effectiveness. We show that the increase in environmental tax reduces consumption risk, while the balanced budget decrease in labour income tax increases income risk. We find that the total welfare effect of a green tax reform differs substantially from the case of certainty. The critical parameters determining the existence of a second dividend are the lump-sum transfers, the relative substitutability of the two goods for leisure, and the initial tax rates relative to their optimal that determine also the response of labour supply to a change in the tax mix.

In Namibia, as in many parts of Africa, households are highly dependent on forest resources for their livelihoods, including energy needs. Using data originally collected for Namibia's forest resource accounts and insights from a non-separable household model, this paper estimates household fuelwood demand. Specifically, the factors underlying the substitution between fuelwood collected from open access forest resources, cow dung, and fuelwood purchased from the market are analysed. Heckman two-step estimates show that households respond to economic scarcity, as measured by the opportunity costs of collecting fuelwood, by reducing energy consumption slightly more than by increasing labour input to collection. There is limited evidence for substitution from fuelwood to other energy sources, particularly with declining availability of forest stocks. Market participants may be more sensitive to price changes than non-participants. All estimated elasticities are low, similar to those observed in previous studies.

Common property resources are often used by households of developing countries as insurance in case of economic stress. The aim of this paper is to consider the potential poverty-trap implications of this use. If the capacity of the resource is low, or if the population in need of insurance is too large, the households are trapped in CPR extraction activity and cannot get more than their subsistence requirement. In this context, cooperation between households and the introduction of a cooperative insurance mechanism may sustain an equilibrium outside the poverty trap and relax pressure on the resource. Moreover, private insurance schemes could also be a potential solution to this poverty trap.

The mopane worm, which is the caterpillar form of the Saturnid moth Imbrasia belina Westwood, is – like other edible insects and caterpillars – a vital source of protein in southern African countries. The worms live and graze on mopane trees, which have alternative uses. With increasing commercialization of the worm, its management, which was hitherto organized as a common property resource, has been degraded to almost open access. This paper uses a bioeconomic modelling approach to show that for some optimal allocation of the mopane forest stock, the restrictive harvest period policy advocated by community leaders may not lead to sustainable harvesting of the worm.

Traditional pastoralist land management institutions in sub-Saharan Africa have been stressed by an increasing human population and related forces, including private enclosure of grazing land; government-sponsored privatization; and the increasing prevalence of violent conflicts and livestock theft. We model the incompleteness and flexibility of traditional grazing rights using fuzzy set theory. We compare individual and social welfare under the traditional system to individual and social welfare under a private property system and a common property system. Whether the traditional system is preferred to private property depends on whether the value of mobility, as defined by the traditional system, is more valuable than the right of exclusion inherent in private property. We find that under some conditions the imprecision which characterizes traditional rights can result in higher social returns than a common property regime characterized by complete symmetric rights across all members of the user group and complete exclusion of non-members.

Based on multiple rounds of household survey data collected in the year after the 1998 massive flooding in Bangladesh, we investigate the role of private transfers as a social coping response to natural disasters. We also explore the role of private transfers (gifts) as an informal insurance mechanism to smooth consumption in the face of an adverse covariate shock caused by the flooding. The level of transfers made is shown to be altruistically calibrated to the severity of flood exposure. As an indicator of the economic importance of such gifts, the amount of transfers received is shown to significantly contribute to reducing household consumption variability. We discuss the policy implications of our findings in a developing country context.

This paper measures environmental efficiency (EE) and environmental productivity (EP) in 38 countries over the period 1971–92 and analyzes differences in these across countries. It explores several macro-economic factors that could explain these differences, such as income levels and the degree of openness in these countries. The average EE and EP indexes are found to be almost steady over the period 1971–92. In the annex-I countries, an increase in income levels initially leads to an increase in the average EE but subsequently to a decline in EE. In non-annex I countries, EE is increasing over the range of income in these countries. This study also finds an EKC type relationship between EP and per capita GDP in annex-I countries. The degree of openness has a significant positive impact on EE in annex-I countries.

This paper, based on a computable general equilibrium model of the Indian economy, shows that a domestic carbon tax policy that recycles carbon tax revenues to households imposes heavy costs in terms of lower economic growth and higher poverty. However, the decline in economic growth and rise in poverty can be minimized if the emissions restriction target is modest, and carbon tax revenues are transferred exclusively to the poor. India's participation in an internationally tradable emission permits regime with grandfathered emissions allocation is preferable to any domestic carbon tax option, provided the world market price of emission permits remains low. Even better would be if India participated in a global system of tradable emission permits with equal per capita emission entitlements. India would then be able to use the revenues garnered from the sale of surplus permits to speed up its economic growth and poverty reduction and yet keep its per capita emissions below the 1990 per capita global emissions level.

We study the economic performance of Benthic Resource Management Areas (BRMAs) in central-southern Chile. The analysis considers 26 managed areas with Agreements of Use declaring Chilean abalone (Concholepas concholepas) to be the main exploited benthic resource from 2001 to 2003. Our analysis explores the role played by several characteristics thought to be potential BRMA performance determinants. These variables were defined and grouped into four types: economic, environmental–biological, institutional–organizational, and organizational leader. Our results indicate that the price of Chilean abalone, the size of the habitable area, the target resource density, the density of other resources, and leader experience are determinant factors for the economic performance of the BRMAs under study.

We estimate annualized values of access to home tap water in three cities in El Salvador, and marginal ‘barrios’ in four Guatemalan cities, using a hedonic price method for studying changes in capitalized home values from obtaining a water connection. A tap water connection is found to add from 10 per cent to 52 per cent to sales values of homes in our sample. The estimated mean values of gaining tap water access represent 1–5 per cent of real household income, differing by city and with generally higher values in El Salvador. On average this gain eliminates between 1 per cent and 3 per cent of the initial difference in real incomes between the groups of connected and unconnected households. We also find large differences in the value of a tap connection depending on the main source of non-tap water, with lowest values when the source is a private well in El Salvador.

Lake Victoria fisheries are important to Tanzanian food security, employment, and foreign exchange, but they have experienced declining performance, largely due to overfishing. This paper studies technical efficiency and skipper skill using Tanzanian fishery data for the two major species, Nile perch and dagaa. The relative level of efficiency is high in both fisheries and several observable variables linked to skipper skill significantly explain the efficiency level.
