An experimental investigation of explanations for inconsistencies in responses to second offers in double referenda 总被引:1,自引:0,他引:1
Anthony C. Burton Katherine S. Carson Susan M. Chilton W. George Hutchinson 《Journal of Environmental Economics and Management》2003,46(3):472
This paper demonstrates the potential for induced preference experiments to test previously unverified explanations of observed behavior in contingent valuation surveys. The NOAA Panel on Contingent Valuation called for experimental evidence on potential biases in the double referendum format. We test Carson, Groves, and Machina's (Incentives and informational properties of preference questions, Plenary address to the European Association of Resource and Environmental Economists, Oslo, Norway, June 1999) simple cost uncertainty and weighted averaging explanations of inconsistent responses to follow-up offers in such double referenda against a baseline of certainty and truthful preference revelation. The results find evidence to support the Weighted Average hypothesis. Results regarding the cost uncertainty hypothesis are more ambiguous and merit further investigation. 相似文献

Mikael Skou Andersen 《Sustainability Science》2007,2(1):133-140
This paper provides an introduction to some of the fundamental principles and approaches in environmental economics which
are of significance to achieving an integrated sustainability science. The concept of a circular economy, introduced by the
late David Pearce in 1990, addresses the interlinkages of the four economic functions of the environment. The environment
not only provides amenity values, in addition to being a resource base and a sink for economic activities, it is also a fundamental
life-support system. Environmental economists have suggested that, taking these four functions as an analytical starting point,
unpriced or underpriced services should be internalised in the economy. In Europe significant advances have been achieved
in the pricing of externalities by means of truly interdisciplinary analysis which accounts in detail for the environmental
consequences. The monetary estimates reached as a result of such interdisciplinary research are gradually being applied to
the economic analysis of environmental policy priorities. Although such figures provide only a partial and incomplete picture
of the environmental costs at stake, they support and inform the analysis of the virtues of a circular economy for individual
resources as well as for sustainability as a future trajectory. 相似文献

Economic development and environmental protection: an ecological economics perspective 总被引:5,自引:0,他引:5
Rees WE 《Environmental monitoring and assessment》2003,86(1-2):29-45
This paper argues on both theoretical and empirical grounds that, beyond a certain point, there is an unavoidable conflictbetween economic development (generally taken to mean 'materialeconomic growth') and environmental protection. Think for a moment of natural forests, grasslands, marine estuaries, salt marshes, and coral reefs; and of arable soils, aquifers, mineraldeposits, petroleum, and coal. These are all forms of 'natural capital' that represent highly-ordered self-producing ecosystemsor rich accumulations of energy/matter with high use potential (low entropy). Now contemplate despoiled landscapes, eroding farmlands, depleted fisheries, anthropogenic greenhouse gases,acid rain, poisonous mine tailings and toxic synthetic compounds.These all represent disordered systems or degraded forms of energy and matter with little use potential (high entropy). The main thing connecting these two states is human economic activity. Ecological economics interprets the environment-economyrelationship in terms of the second law of thermodynamics. The second law sees economic activity as a dissipative process. Fromthis perspective, the production of economic goods andservices invariably requires the consumption of available energy and matter. To grow and develop, the economynecessarily 'feeds' on sources of high-quality energy/matter first produced by nature. This tends to disorder and homogenizethe ecosphere, The ascendance of humankind has consistently been accompanied by an accelerating rate of ecological degradation, particularly biodiversity loss, the simplificationof natural systems and pollution. In short, contemporary political rhetoric to the contrary, the prevailing growth-oriented global development paradigm is fundamentally incompatible with long-term ecological and social sustainability. Unsustainability is not a technical nor economic problem as usually conceived, but rather a state of systemic incompatibilitybetween a economy that is a fully-contained, growing, dependent sub-system of a non-growing ecosphere. Potential solutions fly inthe face of contemporary development trends and cultural values. 相似文献

Incorporating natural capital into economy-wide impact analysis: a case study from Alberta 总被引:1,自引:0,他引:1
Patriquin MN Alavalapati JR Adamowicz WL White WA 《Environmental monitoring and assessment》2003,86(1-2):149-169
Traditionally, decision-makers have relied on economic impactestimates derived from conventional economy-wide models. Conventional models lack the environmental linkages necessary for examining environmental stewardship and economic sustainability, and in particular the ability to assess the impact of policies on natural capital. This study investigatesenvironmentally extended economic impact estimation on a regionalscale using a case study region in the province of Alberta knownas the Foothills Model Forest (FMF). Conventional economic impactmodels are environmentally extended in pursuit of enhancingpolicy analysis and local decision-making. It is found that theflexibility of the computable general equilibrium (CGE) modelingapproach offers potential for environmental extension, with a solid grounding in economic theory. The CGE approach may be the tool of the future for more complete integrated environment andeconomic impact assessment. 相似文献
