Ecotourism as a conservation tool and its adoption by private protected areas in Brazil 总被引:1,自引:0,他引:1
Ecotourism in private reserves combines the establishment of protected areas with an incentive mechanism to conserve biodiversity. Brazil's private reserve system is well-established but little is known about its links to tourism. This study puts the global private protected area into context and quantifies the extent to which ecotourism has been adopted as a sustainable land-use practice on private reserves in Brazil. Our findings demonstrate that small reserves do contribute to conservation and are used for ecotourism. The belief that large reserves are necessary for ecotourism and conservation is challenged. Only 4% (n = 45) of the 1182 reserves are engaged in ecotourism, mainly those within the Atlantic Forest biome and these are generally small in size (<50 ha). Reserves provide modest to basic accommodation as well as education and economic opportunities that include adjacent communities. Hiking and bird watching are the most popular activities but many reserves are threatened by poaching and invasive species. The low adoption of ecotourism appears due to a combination of factors, including lack of landowner interest, constraints imposed by regulations, logistics and anthropogenic threats. Nonetheless, there is potential to expand ecotourism within private reserves as 143 further private reserves are located near those already engaged in ecotourism. 相似文献

This article scrutinizes the much used, but less examined, concept of ‘trickle down' in an urban setting. We make a distinction between the production of and distribution in the city, and argue that trickle down in contemporary urban policy could be regarded as the liberal link between production and distribution. Based on interviews with key figures and document analyses, we look at the transformation of the Swedish city of Malmö from an industrial to a post‐industrial city, where, during the last two decades, we have found three concurrent components: the ideology of trickle down; several urban policy programs and governmental policies to ‘make' money and resources trickle down; as well as increased economic polarization and segregation. A liberal critique of trickle down would argue that market mechanisms cannot by themselves solve distribution, and that government policies therefore are needed. We argue for the need to go beyond a liberal critique of trickle down and stress how unequal distribution is built into the unequal production of the city. 相似文献

The article examines the effect of membership in farmer groups (MFG) on adoption lag of agricultural technologies and farm performance in Burundi, the Democratic Republic of Congo and Rwanda. We use duration and stochastic production frontier models on farm household data. We find that the longer the duration of MFG, the shorter the adoption lag and much more so if combined with extension service delivery. Farmer groups function as an important mechanism for improving farm productivity through reduced technical inefficiency in input use. We discuss policy implications under which farmer groups are a useful channel to reduce adoption lag, and the means through which improved farm performance can be achieved. 相似文献

Abstract This paper studies the impact of a wage subsidy program aimed at long‐term social assistance recipients in Quebec. The program closely mimics the Self‐Sufficiency Project and was implemented for a trial period of one year in 2002.We focus on the labour market transitions of the targeted population starting one year before the implementation of the program and until the end of 2005. Our results show that the duration of spells off social assistance increased, while the duration of social assistance spells decreased slightly. The response to the program varies considerably with both observed and unobserved characteristics. 相似文献

We investigate the relationship between firm strategy and the use of performance measures in executive compensation. Our analysis shows that there is an increased emphasis on sales in the determination of executive compensation for firms pursuing a cost leadership strategy, which seek to achieve their competitive advantage through low price and high volume. In contrast, there is a decreased emphasis on accounting measures in firms pursuing a differentiation strategy, which require investments in brand recognition and innovative products, investments that are subject to unfavorable accounting treatment. These results indicate that compensation committees link executive rewards to firm strategy. 相似文献

The paper challenges the assumptions regarding the adequacy of the organization of information in support of communication and dialogue. Beyond the over simplification of bullet points, and recognition of nested menu items and discussion threads, the question is what further structuring can be envisaged and how can its many possible levels be fruitfully distinguished to enable the emergence of more integrative and mature modes of discourse. The argument is presented as important to the support of higher orders of collective intelligence. Use is made of the weaving metaphor to contrast with the cognitively alienating conventional representation of system diagrams and concept maps. 相似文献

While using financial incentives to increase fertility has become relatively common, the effects of such policies are difficult to assess. We propose an identification strategy that relies on the fact that the variation in wages induces variation in benefits and tax credits among ‘comparable’ households. We implement our approach by estimating a discrete‐choice model of female participation and fertility using individual data from the French Labor Force Survey and a detailed representation of the French tax–benefit system. Our results suggest that financial incentives have had a significant effect on fertility decisions in France. As an example, we simulate the effects of an additional, unconditional child credit of 150 euros per month. The effects are strongest for the third child.

In a previous paper, we showed how a pay-as-you-go social security scheme, based on voluntary contributions, can be an appropriate institution to reach an optimal sharing of risks among generations in the presence of demographic uncertainties. We study here the functioning of such schemes when there are different population strata, with different demographic shocks and wages. We show that while a collective voluntary pay-as-you-go scheme can provide efficient intergenerational risk sharing, it is likely to be destabilized by pensions funds specialized by agents' types. This is true both when there is a complete set of contingent markets, where the risk pooling capabilities of a collective fund are potentially of less interest, and when markets are incomplete. In this last circumstance, a collective fund may help the living agents to share their intragenerational risks. However, we show that the resulting allocation does not Pareto dominate the outcome of individual funds by agent types, and that there are incentives for agents to separate from any collective organization. 相似文献

We study the economic consequences of alternative hedge accounting rules in terms of managerial hedging decisions and wealth effects for shareholders. The rules we consider include the fair-value and cash-flow hedge accounting methods prescribed by the recent SFAS No. 133. We illustrate that the accounting method used influences the manager's hedge decision. We show that under no-hedge accounting, the hedge choice is different from the optimal economic hedge the firm would make under symmetric and public information. However, under a certain definition of fair-value hedge accounting, the hedging decision preserves the optimal economic hedge. We then demonstrate that long-term and future shareholders prefer a certain definition of fair-value hedge accounting to no-hedge accounting, while short-term shareholders prefer either approach depending on risk preferences and the level of uncertainty. We speculate about circumstances in which a manager would choose not to adopt fair-value hedge accounting when he has the option not to do so. 相似文献
