The paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation.Using a recursive specification of time preferences, we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation. We examine the relationships between economic growth and environmental quality. Endogenous discounting provides new insights in the economic dynamics underlying the environmental Kuznets curve. By treating growth as endogenous, we examine how externalities and economic growth interact with each other. We investigate how economic development can contribute to an increased demand for environmental preservation. As an important new result, we also show how poverty can contribute to environmental degradation.  相似文献

This paper examines the impact of various socio-economic factors on consumption in rural West Bengal, an eastern state of India, using a regression-based technique reformulated in a spatial framework. The difference of incidences of poverty (head count ratios) in two parts (North and South) of rural West Bengal is then decomposed using the familiar Oaxaca decomposition methodology into an aggregate characteristics effect, which is interpreted as a resource effect and an aggregate coefficients effect, which is interpreted as an efficiency effect. An important observation from the present analysis is that the poorer North Bengal has a scarcity in terms of availability of characteristics (resources) compared to that in South Bengal and the resource scarcity in North Bengal is the dominant factor causing the poverty gap between the two parts of West Bengal. Thus, attention needs to be paid to North Bengal with respect to enhancement of important policy variables like education level, Government aid, and employment opportunities.  相似文献

Campbell (1980) and following authors have discussed a limited resource extraction capacity as an augmentation of the well‐known Hotelling model. We integrate a limited extraction capacity and related investments in the endogenous growth model of Tsur and Zemel (2005) to study its effect on economic development. The capacity constraint gives rise to three effects. On the one hand, higher energy costs and the reallocation of production towards capacity investments decrease production available for consumption, research and/or capital investments (energy costs and reallocation effect). On the other hand, research investments may increase, which boosts available production (research effect). Depending on the capital endowment and the strength of the effects, long‐run consumption may be boosted or depressed. In particular, the capacity constraint may render everlasting consumption growth non‐optimal in a resource‐rich economy. Furthermore, we find that capacity investments may be postponed to later points in time if the capital endowment is high.  相似文献

Fiscal considerations may shift governmental priorities away from environmental concerns: finance ministers face strong demand for public expenditures such as infrastructure investments but they are constrained by international tax competition. We develop a multi-region model of tax competition and resource extraction to assess the fiscal incentive of imposing a tax on carbon rather than on capital. We explicitly model international capital and resource markets, as well as intertemporal capital accumulation and resource extraction. While fossil resources give rise to scarcity rents, capital does not. With carbon taxes, the rents can be captured and invested in infrastructure, which leads to higher welfare than under capital taxation. This result holds even without modeling environmental damages. It is robust under a variation of the behavioral assumptions of resource importers to coordinate their actions, and a resource exporter’s ability to counteract carbon policies. Further, no green paradox occurs—instead, the carbon tax constitutes a viable green policy, since it postpones extraction and reduces cumulative emissions.  相似文献

The “subsistence fund” was once an integral part of Austrian business cycle theory to indicate the resource constraint on the ability to complete investments. Early agrarian and industrial economies were constrained by resource availability in a manner consistent with that alluded to by the subsistence fund. This link became more tenuous as the growth of the financial economy in the twentieth century removed the apparent importance of pre-saved goods to complete investments. At this point the subsistence fund came to be used only as a metaphor and was jettisoned from Austrian business cycle theory. The present paper points to the merits of the subsistence fund in explaining the turning point of the business cycle as compared to alternative explanations. It also works out the deficiencies in historical expositions of the Austrian theory based on the subsistence fund, and traces the evolution of the resource constraint at the core of Austrian economists´ treatment of the business cycle.  相似文献

In many developing countries, decentralization programmes for natural resource management aim to induce incentives for sustainable resource management at the local level. The effectiveness of such programmes has, however, suffered from weak property rights to the resource and by the presence of externalities. Growing economic integration among countries has exacerbated these problems by increasing the exposure of local user groups to commercial actors interested in resource extraction. In this paper, the interplay of decentralization and globalization in affecting environmental outcomes and community welfare is analysed through a game-theoretic model of community-firm interactions. The results highlight the complexities of policy design. First, by raising the extractive value of the resource, globalization may lead to communities negotiating resource extraction agreements with firms. Second, with a lack of effective state enforcement of community resource rights, communities may be unable to assume de facto ownership over the resource, while commercial actors succeed in exploiting resources without community consent. No single policy option provides a panacea to counteracting these negative effects. Instead, a mix of policies, combining incentive payments along with the provision of more secure property rights and poverty alleviation is shown to have the potential to improve both environmental outcomes and community welfare.  相似文献

The role of agriculture in development remains much debated. This paper takes an empirical perspective and focuses on poverty, as opposed to growth alone. The contribution of a sector to poverty reduction is shown to depend on its own growth performance, its indirect impact on growth in other sectors, the extent to which poor people participate in the sector, and the size of the sector in the overall economy. Bringing together these different effects using cross-country econometric evidence indicates that agriculture is significantly more effective in reducing poverty among the poorest of the poor (as reflected in the $1-day squared poverty gap). It is also up to 3.2 times better at reducing $1-day headcount poverty in low-income and resource rich countries (including those in Sub-Saharan Africa), at least when societies are not fundamentally unequal. However, when it comes to the better off poor (reflected in the $2-day measure), non-agriculture has the edge. These results are driven by the much larger participation of poorer households in growth from agriculture and the lower poverty reducing effect of non-agriculture in the presence of extractive industries.  相似文献

Assessing poverty-deforestation links: Evidence from Swat, Pakistan   总被引:1,自引:0,他引:1  
This paper contributes to the debate on the links between poverty and forestry degradation; the view that due to poverty and the meeting of subsistence needs the poor use natural resources more intensively and hence cause them to degrade. Using the case of the forest rich Swat district, Pakistan, the paper addresses the issue empirically, historically, and institutionally. We do not find empirical support for the “poverty-environment nexus”, in that the poor and other income groups are equally resource dependent and also show that resource degradation is not associated with poverty. Our historical and institutional analyses provide alternative explanations for resource degradation. Selective and rotating ownership patterns, starting with the 17th century, provided limited incentive for resource conservation. It also created tension between de jure and de facto owners, that has persisted, and is one source of forest degradation. Ill-defined resource rights have also exacerbated the impacts of several other factors contributing to forest degradation which is compounded by poor management, corruption, and perverse incentives.  相似文献

Inter-provincial migration and inequality during Vietnam's transition   总被引:2,自引:0,他引:2  
Vietnam's economic boom during the transition to a market economy has centered on very rapid growth in some sectors and provinces, yet poverty has diminished across the entire country. With capital investments highly concentrated by province and sector, geographic labor mobility may be critical in spreading the gains from growth. Conversely, rising income inequality may be attributable in part to impediments to migration. We first use census data to investigate migration patterns and determinants. We then examine the role of migration as an influence on income ratios between pairs of provinces. The former analysis robustly confirms economic motives for migration but also suggests the existence of poverty-related labor immobility at the provincial level. Examination of income ratios between pairs of provinces reveals that the impact of migration on inequality can be either negative or positive. A robust inequality-reducing impact of migration is found for migration flows into provinces where most of Vietnam's trade-oriented industrial investments are located.  相似文献

论退耕还林与减缓山区贫困的关系   总被引:2,自引:0,他引:2  
现有扶贫开发模式以改善贫困地区生产条件和开发资源为导向,但是对生态较为脆弱的大多数贫困山区来讲,若不考虑社区生态系统的保护,开发式扶贫有可能导致越扶越贫。本文在分析山区贫困的一般特征基础上,通过对有关环境与贫困相互关系的理论认识,结合正在推进的退耕还林工程实践,提出林业扶贫是减缓山区贫困的有效途径,指出应从落实山区林权制度、建立生态移民制度、改善农业补贴制度以及强化山区扶贫管理体制等方面创新山区扶贫开发模式。  相似文献

This paper investigates how cooperation among users can achieve a better management of groundwater in the presence of environmental externalities. Cooperation allows users to internalize the damages caused by their activities and reduce extractions. The paper develops a game theoretical framework to assess the value of cooperation in an aquifer that is divided into three sub-aquifers that are being overly exploited. Two types of externalities are modeled: first, water extractions in each sub-aquifer impact water levels in neighboring sub-aquifers (extraction externality). Second, the three sub-aquifers are also connected to an ecosystem and thus decisions in each sub-aquifer affect the health of the ecosystem (environmental externality). A cooperative game theory model is applied. The model empirically shows how the uncontrolled extractions in each sub-aquifer affects neighboring groundwater users but also cause severe impacts to the linked ecosystem. The model is tested empirically in one of the most important aquifers in Spain, the Eastern la Mancha aquifer. The results illustrate how both extraction and environmental externalities interact in affecting the likelihood of cooperation among the users. The paper estimates the value of cooperation and its stability with and without the environmental externality.  相似文献

The tourism sector's contribution to economic development depends upon complex and dynamic socioeconomic, environmental, and institutional factors. Policymakers require objective evidence to base decisions on which public policies or investments to pursue. In this paper we develop an economy‐wide approach to assessing public investments in tourism. The approach is powerful in that it considers all inter‐sectoral linkages that are critical for tourism‐sector analysis. This framework is linked to a microsimulation module that enables estimation of household‐level and destination‐specific impacts and the distribution of benefits. To illustrate the framework and the insights it can generate, we apply it to a public investment in Belize's Cayo District. Our findings show that the overall level of economic activity increases while an appreciation of the real regional exchange rate results in slower growth in traditional nontourism exports. Greater availability of capital and labor to meet increased demand would reduce this effect. The investment results in a reduction in the poverty headcount on the order of 0.7 percentage points, though there is a small increase in inequality that is a function of the skill requirements of the new positions created as a result of the investment.  相似文献

This paper investigates the impact of economic growth, and more specifically robust economic growth along with other macroeconomic determinants, on poverty levels using both the U.S. official measure of poverty and an estimated time series of Sen indices of poverty. The results reveal that the period of robust economic expansion that the U.S. economy experienced during the 1990s did not have a significant impact on poverty using either measure. In addition, we find that the impact of growth and other macro controls is dramatically different when a subset of the poverty population, namely non-white poverty, is investigated. The percentage of households headed by women is shown to be a significant factor in examining poverty for this subgroup.  相似文献

An attempt is made in this article to demonstrate that Alfred Marshall and John Maynard Keynes erected a number of signposts that point in the direction of a normative, institutional and policy-oriented social economics of labor. They opined that dysfunctioning institutions had thrown most members of the working class into an abyss of poverty. According to Marshall, poverty was caused by institutional neglect of education for the masses. Hence he recommended a drastic overhaul of those institutions that impinged on education. Keynes argued that the rentiers were the villains because they had intentionally reduced their funding of entrepreneurial investments. Consequently, investments dwindled and unemployment caused working-class poverty to rise above its customary levels. Keynes's solution was public investment in private enterprises, which he called socialization of investment. This would cause euthanasia of the anti-social rentiers. Because of their recommendations, Marshall and Keynes called themselves socialists.  相似文献

China has been heavily investing in transportation infrastructure since the 1990s. Consequently, connectivity has been significantly improved, both within China and between China and other countries. Such large‐scale investments have been made possible by various financing mechanisms from the central government, local governments, and the private sector. Research findings generally indicate that these infrastructure investments bring economic prosperity to the country, affect the distribution of economic activities, reduce poverty to a certain extent, and promote economic integration. The future trends of connectivity changes in China and relevant policy recommendations are also discussed in this paper.  相似文献

Emergy theory and method are used to evaluate the feasibility of an irrigation improvement project in China and its contribution to local agricultural development. An emergy method for evaluating the costs and benefits of the project and a composite index named the emergy cost-benefit ratio (EmCBR) were developed. The emergy evaluation shows that the major costs associated with the proposed project come from earthwork (77.4% of the total cost) and concrete work (15.4%), and that water saving (43.0% of the total benefit) and agricultural yield increase (56.9%) are the most important contributions. The calculated EmCBR is 0.97 (the lowest value for a feasible project is 1.0) which indicates that this project would not be feasible in emergy terms. The regional agricultural system could not benefit from the proposed project, according to several emergy indices: emergy yield ratio (EYR), emergy investment ratio (EIR), environmental load ratio (ELR) and environmental sustainability index (ESI). The results show that conventional cost-benefit analysis could fail to provide an adequate decision-making framework because it is unable to value resources and environmental impacts properly. More additional emergy evaluations should be completed on other alternatives to the proposed project to provide adequate guidelines for selecting the best alternative that contributes most to agricultural development with limited environmental impact.  相似文献

When measuring poverty in developed countries, the poverty line used to identify the poor is usually relative and set as a percentage of the median (or of the mean) of the total income. In consequence, when poverty is analyzed over a period of time, changes in the poverty level depend on the impact of evolving standards. To eliminate this effect, sometimes, an anchored poverty line is used. Furthermore, changes in the mean of the distribution and in the inequality among the poor may also affect the poverty levels. This note proposes a decomposition of the changes in poverty as the sum of four terms. The first two reflect the impact in poverty of changes in living standards and the other two measure the effect of the distributional growth and redistribution. This decomposition will help policymakers in the implementation of a more specific antipoverty agenda. An application with data from the European Union Survey on Income and Living Conditions shows the potential of the decomposition proposed.  相似文献
