Natural capital contributes to the quality of life of a region in two complementary ways: first, by directly providing environmental services that cannot be imported, and second, by supplying the natural resources that, through a human controlled production process, become valuable to humans. The evolution of the combination of these two components of the quality of life determines the path of development a region takes. Environmental services also determine the ability of natural capital to regenerate itself. Ecosystems and other components of the regional natural capital produce environmental services that provide life-support functions necessary for natural capital reproduction. The destruction of this critical natural capital impairs the internal sources of improvement of the quality of life of a region, leading to a non-sustainable path of development. This article describes a model of the relationship between natural capital and quality of life that provides a stricter definition of sustainable development through explicit characterization and classification of natural capital according to its ability to produce life-supporting environmental services, by its substitutability, and by its possible reconstruction. Application of this model then shows that there are 51 possible regional development paths, only 32 of which are sustainable and only 14 of which are sustainable while also providing improvements in quality of life. Only six of these 14 sustainable development paths are attained with economic growth, however, while the other eight paths increase quality of life by increasing the production of environmental services. The model could help in the development of institutional interventions that would promote regional development paths that are sustainable. 相似文献

A new valuation question: analysis of and insights from interval open-ended data in contingent valuation 总被引:1,自引:1,他引:0
Cecilia Håkansson 《Environmental and Resource Economics》2008,39(2):175-188
This paper introduces a type of open-ended valuation question where respondents state their willingness to pay in the form
of an interval rather than a point estimate. Allowing the response to be expressed as an interval has advantages compared
to traditional valuation questions: it captures potential valuation uncertainty, facilitates interpretation of uncertainty
and most importantly, provides a richer set of information about individuals’ preferences. Furthermore, an open-ended willingness
to pay format has advantages if a survey is carried out in more than one country. Too little is known about valuation uncertainty
to represent willingness to pay only as an exact value. Therefore, this value should be complemented by upper and lower boundary
estimates. In this paper I present new methods for estimating these different values. The methods are illustrated with results
from a survey concerning wild salmon in the Vindel River, northern Sweden. The results suggest that the upper and lower boundaries
provide a kind of confidence interval for the willingness to pay, which is encouraging for estimating these values to characterise
willingness to pay. The results also illustrate that some earlier criticism in the literature of open-ended questions does
not apply to the question presented in this paper. 相似文献

Most economists have not yet grappled with the demands of intersectional scholarship, which recognizes the intertwined nature of gender, race, class, caste and other influences on the economic situation of individuals and groups. Among economists, feminist economists may have made the most progress and be best positioned to break further ground, though we can do better and much remains to be done. This article synthesizes the case for intersectional work, reviews the state of the economic literature, describes the contributions of the articles in this special issue of Feminist Economics on "gender, color, caste and class," and sketches directions for the future. 相似文献

This article develops and tests a segmentation scheme for the U.S. Hispanic market based on the extent and nature of acculturation. Acculturation is conceptualized as driven by language preferences and two dimensions of cultural identification, Hispanic and American. Structural equation modeling develops and assesses the proposed scales, and a latent class clustering procedure (latent discriminant analysis) tests propositions on a sample of 403 U.S. Hispanics. Consistent with theory, four clusters of U.S. Hispanics emerge: retainers, biculturals, assimilators, and non-identifiers that vary according to language preference and cultural identification. 相似文献

Los autores dan cuenta de una investigación sobre los perfiles personales y académicos de hombres y mujeres con responsabilidades directivas en empresas españolas, su situación profesional y su postura respecto a la igualdad de género. Las directivas españolas son más jóvenes que sus homólogos masculinos, pero los alcanzan o superan en cualificación profesional y tienen menos hijos que ellos. Sin embargo, siguen luchando contra las barreras que impiden el aprovechamiento pleno del enorme capital humano femenino. A pesar de las medidas tomadas, más de nueve de cada diez puestos directivos siguen ocupados por hombres. 相似文献
