This article addresses the societal and cultural aspects of bioreserves and environmental restoration programmes. It begins with a discussion of bioreserves, then uses the example of a Man and Biosphere (MAB) inspired study of the US Everglades to illustrate how land has been shaped historically by culture and technology. It then demonstrates how current conflicts of values and culture, from both inside and outside the region, from interest groups with both pragmatic and emotional stances, are determining the future of an environment—the Everglades. The article thereby shows how human values and perceptions impact on the development of a sustainable Everglades, using the findings of surveys and public meetings to highlight the interests of the competing communities, ethnic and interest groups involved. If bioreserves are to survive they cannot become alienated from the people in the regions in which they are located. 相似文献

Steven R. Tabor 《Bulletin of Indonesian Economic Studies》1989,25(2):31-51
Aggregate agricultural commodity demand parameters are estimated, based on an application of the Deaton and Muellbauer Almost Ideal Demand System to a seventeen year Indonesian time-series data set of prices, expenditures and consumption availability. The statistical results are generally significant and correctly signed. The revealed demand relationships imply that the Indonesian food Staples are normal goods. Expenditure elasticities are higher for the higher value foodstuffs than for the lower value starchy staples. Furthermore, the demand for rice has become highly inelastic to both own and cross-price interventions. This implies that rice price interventions will require a high degree of fine-tuning in order to stabilise prices effectively, and that low urban rice prices cannot be regarded as an appropriate, or even second best policy instrument for improving nutritional status.
A high degree of Substitution between rice and secondary food crops, and amongst groups of secondary food crops, is identified. The significance of the cross-price elasticities for the secondary food crops suggests that single-market interventions will have non-trivial budget-mediated effects in other commodity markets. The management of a multi-commodity food policy requires that the spillover effects from commodity pricing policy must be taken into account in order to optimise the effects of price policy interventions. 相似文献

Optimal new-product pricing in regulated industries 总被引:1,自引:0,他引:1
Intertemporal pricing issues faced by regulated monopolists in market settings characterized by high rates of innovation have received little attention in the regulatory economics literature. Most analyses of regulatory pricing have focused on monopolies characterized by a stable multiple-good product set. In a regulated industry characterized by technological change in the form of new products and services (such as telecommunications), optimal pricing decisions may also reflect intertemporal market and production factors. In this paper, two such intertemporal factors are modeled: learning curve effects on the firm's cost function, and customer demonstration effects on the demand side of the market. Inclusion of these factors leads to an intertemporal pricing rule that may conflict with the standard regulatory practice whereby each product or service must recoup its own resource costs period by period. Our results suggest that this regulatory practice can result in efficiency losses, since it results in a rate of technological diffusion that is too low. 相似文献

The critical state of the hospital industry, as previously described, generates a difficult decision environment for the materiel manager and those in the purchasing function. The unique life- and death circumstances of hospitals impose a further onus on those who manage them. In the name of saving lives, they can find a convenient excuse to disregard all moral principles, forgetting the Socratic dictum "it is not enough that one lives, but that one lives well." Without the moral "right stuff," they can easily give in to the seductions of momentary gains and glory through ethical short-cuts. There is wisdom and consolation in the words that "nice guys may appear to finish last, but usually they're running in a different race." Studies have established a direct relationship between corporate excellence and ethical values. The reality of competition in the hospital industry dictates that the integration of ethics into the life of the organization should happen by design and not by accident. This is what is meant by strategy. If hospitals would strive for excellence to survive and grow, they should have a strategy with a mission statement that also embodies its moral values and moral agenda. Such an approach does not guarantee that an organization will become immune to moral contamination, but it does provide an antidote. 相似文献

"A model of household formation by the young is specified and estimated. It was found that the headship rate for the young in the United States depends on income, the cost of housing, the number of families receiving AFDC payments, the age at first marriage for females and for males, and the percentage of males enrolled in college. Household formation by the young is much more sensitive to changes in income and the price of housing than household formation by the entire adult population. The estimated results are used to examine the change in the headship rate from 1961 to 1979 and from 1979 to 1987." 相似文献
