Comparisons of the costs of reduced-impact (RIL) and conventional logging (CL) based on new data from Gabon and 10 previously published studies revealed that some tropical forest operators should adopt RIL out of financial self-interest but many may require other motivation. Among the comparisons in which costs were expressed per cubic meter of harvested timber, three reported lower costs for RIL, one showed identical costs with CL, and six reported RIL to be more costly. 相似文献

Although balancing work-related and non-work-related time demands is an ongoing concern for many hotel workers, there is a dearth of research examining workers’ satisfaction with their work schedule flexibility. Using a sample drawn from nine different hotel properties in South Korea, this study finds that workers’ levels of emotional intelligence and overall job satisfaction serve as antecedents of their schedule flexibility satisfaction. Moreover, the study also finds that decreased turnover intent is a consequence of schedule flexibility satisfaction. Based upon these findings, both managerial and research implications are presented. 相似文献

For allocation problems with one or more items, the well-known Vickrey–Clarke–Groves (VCG) mechanism (aka Clarke mechanism, Generalized Vickrey Auction) is efficient, strategy-proof, individually rational, and does not incur a deficit. However, it is not (strongly) budget balanced: generally, the agents' payments will sum to more than 0. We study mechanisms that redistribute some of the VCG payments back to the agents, while maintaining the desirable properties of the VCG mechanism. Our objective is to come as close to budget balance as possible in the worst case. For auctions with multiple indistinguishable units in which marginal values are nonincreasing, we derive a mechanism that is optimal in this sense. We also derive an optimal mechanism for the case where we drop the non-deficit requirement. Finally, we show that if marginal values are not required to be nonincreasing, then the original VCG mechanism is worst-case optimal. 相似文献

The Amazon rain forest harbors some of the world's richest biological diversity. During the twentieth century, two types of actors cleared that forest: native Amazonians and outside encroachers. Of the two actors, we know more about what drives outside encroachers to clear forest than about what drives native Amazonians to clear forest. The past research focus has served well because during the twentieth century outside encroachers cleared most of the Amazonian forest. But the past research focus needs to be expanded because native Amazonians are claiming de jure stewardship of the forests they inhabit, and with tighter jurisdiction over those forests will likely come changes in the amount of forest native Amazonians clear. Prior research in rural areas of low-income nations suggests that household income affects household forest clearance. To estimate the effects of household real income on the total forest area (old-growth + fallow) cleared by households we use a panel composed of five annual household surveys (2002-2006, inclusive) from 324 households of a native Amazonian society in Bolivia (Tsimane'). We control for household and village fixed effects and use an instrumental variable for household income. We find positive and significant household real income elasticities of forest clearance of 0.35 and 0.47 and an increase in forest clearance of 5.3%/year. The main finding stood up well to sensitivity analysis. These estimates suggest that in the near future, the forest in the Tsimane' territory will likely face increasing pressure from the Tsimane' themselves, not just from outside encroachers. 相似文献

Identifying Ecotourists in Belize Through Benefit Segmentation: A Preliminary Analysis 总被引:1,自引:0,他引:1
Vincent Palacio 《Journal of Sustainable Tourism》2013,21(3):234-243
Understanding the perceived benefits of nature-based or ecotourism is an important step in providing products usable to the visitor and in developing a sustainable tourism policy. There are few published studies segmenting the nature-based tourism market using a benefit segmentation approach. This study, based on a sample of visitors to Belize, a widely known ecotourism country, identifies tourist segments, based on a multivariate analysis. Ecotourists' comprised less than 20 of the random sample of visitors taken during the tourist season. Ecotourists differed from other segments in terms of social-demographic and trip characteristics, but had similar levels of activity participation. The results suggest several implications for nature-based product promotion and development, and implementation of a sustainable tourism policy. 相似文献

Seasoned equity offering (SEO) underpricing has increased dramatically since the early 1980s. While previous research has examined the determinants of SEO underpricing, these studies have not explored the effect of insider ownership on discounts. We find that this effect is twofold. First, higher insider ownership reduces float, thereby increasing price pressure and SEO underpricing. This effect is greatest in firms with low liquidity. Second, the greater the percentage of secondary shares offered, the lower the underpricing, suggesting that manager's pressure banks to reduce underpricing when their personal wealth is at stake. However, we find that this negative relation is mitigated if the firm employs a prestigious underwriter. 相似文献

Urban Sprawl and Farmland Prices 总被引:1,自引:0,他引:1
Grigorios Livanis Charles B. Moss Vincent E. Breneman Richard F. Nehring 《American journal of agricultural economics》2006,88(4):915-929
A theoretical model of farmland valuation is developed to explicitly account for three effects of urban sprawl: conversion of farmland to urban uses, effect on agricultural returns, and speculative effect as represented by farmland conversion risk. This model is estimated using county-level data in the continental United States. Evidence is found for all three effects of urban sprawl on farmland values. Counties more accessible to major urban centers have higher net agricultural returns. Subsidiary evidence supports that the latter effect may be attributed to survival of (or conversion to) high-valued agriculture around urban centers. 相似文献
