Place attachment,host–tourist interactions,and residents’ attitudes towards tourism development: the case of Boa Vista Island in Cape Verde

A clear understanding of residents’ attitudes towards tourism development and its determinants is a crucial pillar for designing tourism development strategies to promote sustainable development. The literature on the influence of host–tourist interactions and place attachment on residents’ attitudes towards tourism development in developing countries is still scarce. To extend knowledge in this field, this study aims at developing and testing a structural model to examine direct and indirect causal effects of place attachment, host–tourist interaction, and perceived positive and negative tourism impacts on the residents’ attitudes towards tourism development in an island tourism destination – Boa Vista Island in Cape Verde. Results suggest that the residents’ attitudes are positively affected by place attachment, host–tourist interaction, and perceived positive impacts; and negatively affected by perceived negative impacts. Host–tourist interaction emerges as the strongest (direct and indirect) determinant of the residents’ attitudes towards tourism development. Moreover, although both positive and negative perceptions of tourism impacts have significant impacts on the residents’ attitudes, the influence of the former is stronger than that of the latter. The paper ends with relevant theoretical and practical implications to promote positive residents’ attitudes towards tourism development in Boa Vista.     

Impact analysis of September 11 on air travel demand in the USA

This study uses an intervention model to look at the impact of the September 11, 2001 terrorist attack on air transport passenger demand in the US. The result showed that both domestic and international air traffic was significantly impacted for 1 and 2 months, respectively. The impact pattern was thus abrupt and temporary, instead of gradual and permanent. The approach also provides better forecasts than the seasonal ARIMA benchmark.

Government Engagement,Environmental Policy,and Environmental Performance: Evidence from the Most Polluting Chinese Listed Firms

This study empirically examines the implementation of environmental policies and how government engagement impacts on a firm's environmental performance based on a sample of Chinese listed firms in the eight most polluting industries over a 10‐year period. The findings of the study demonstrate that government engagement, measured as ownership structure, is positively correlated with environmental performance, measured by environmental capital expenditure, for state‐owned firms, but no significant relation is found for non‐state‐owned firms. In addition, non‐state‐owned firms are more likely to perform better in terms of environmental investment after the 2006 enactment of a new policy explicitly linking environmental issues with political incentives to regional governments. This study also reports that corporate environmental performance impairs firm value for state‐owned firms but has no impact on firm value for non‐state‐owned firms, suggesting that investors negatively respond to environmental investments made by state‐owned firms as a result of government engagement/political pressure.

工资差异均值分解的一种新改进

本文在评述Oaxaca、Blinder、Cotton和Neumark等学者关于"指数基准问题"(index number problem)研究之演进及其局限的基础上,提出并论证了一种更具解释力的"无歧视工资结构"新形式,以更准确地推断Oaxaca-Blinder分解中歧视的大小程度。文章在对指数基准进一步挖掘、矫正和逼近的同时,从理论抽象和现实操作两个层面优化了工资差异的均值分解,深化了对歧视的理解和刻画。     

The dynamic welfare cost of seignorage tax and consumption tax in a neoclassical growth model with a cash-in-advance constraint

Using a public finance approach, this study investigates welfare costs between seignorage and consumption taxes in a standard growth model. One of these two taxes is used to finance exogenous public spending to balance the government budget. The steady-state welfare cost of consumption taxes is lower if the consumption effect dominates the leisure effect. This paper compares equilibrium along transitional dynamic and steady-state paths and finds that because of lower consumption and leisure and thus higher welfare costs of consumption taxes during early periods, the welfare cost of consumption taxes is larger than the welfare cost of seignorage taxes.     

The implications of environmental costs on air passenger demand for different airline business models

Various environmental measures, including both regulations and fiscal instruments, have been used at airports globally to reduce the impacts of aircraft noise as well as aircraft engine emissions. Internationally, it is recognized that the costs of environmental and social externalities of air transport must be internalized and paid for by the aviation industry and its users. The use of noise related charges or taxes, which theoretically should be based on their respective social costs, has been proved to be effective at some European airports. This research aims to investigate the impacts of environmental costs, through environmental charges, on air passenger demand for different airline business models. The paper presents the mathematical models measuring the social costs of aircraft noise and engine emissions as a basis for setting up environmental charges. Six intra-European short-haul routes in two city pairs, namely London–Amsterdam and London–Paris, are selected for the empirical analysis. The environmental charges are then hypothetically applied to airlines with two different business models, full service carriers (British Airways and Air France-KLM) and low cost airlines (EasyJet). The results show that the potential percentages of demand reduction for both leisure and business passengers would be higher for Easyjet's markets, although with less environmental cost per passenger.     

商品贸易结构变动对劳动收入份额的影响

本文从贸易结构变动出发为研究我国劳动收入份额变动的原因提供一种新的视角。近年来我国商品贸易结构发生了重要变动。理论分析表明,对外贸易不仅通过国际分工和专业化对劳动收入份额产生直接影响,还通过要素密集度变化和技术进步偏向等机制产生间接影响;实证研究发现,出口发展对我国劳动收入份额具有显著的负向作用,进口发展则具有正向作用。进出口贸易对不同要素密集度行业的影响程度与方向存在差异。
